The nature vs. nurture debate is the long-standing argument over whether heredity (nature) or environment (nurture) plays a greater role in developing human characteristics and behaviors. 

Nature refers to the biological characteristics we are born with, including genetic predispositions toward certain traits. In contrast, nurture includes external influences that shape us, such as culture, relationships, and everyday experiences.

For example, when it comes to personality development, some people believe that genetics play a stronger role than environmental factors; this would be considered a nature-focused perspective. 

Others may view the environment as more important. In this case, a nurturing upbringing could help individuals develop their personalities. Therefore, both sides can have valid arguments for their respective positions in the debate.

The Nature Perspective

In the context of the nature vs. nurture debate, nature refers to biological heredity and genetic predispositions inherited by individuals from their parents at birth. 

Buheji (2018) states that:

“in the “nature vs. nurture” debate, nature refers to an individual’s innate qualities (nativism)” (p. 221).

This includes physical characteristics such as eye color, facial features, personality traits, and behavioral tendencies.

Genes determine the unique physical characteristics of each individual while also influencing psychological and social behavior.

Some research implies that roughly 50% of an individual’s personality and disposition are pre-determined by genetics (Bouchard & Loehlin, 2001).

However, Krueger and colleagues (2008) state that the interplay between gene-environment interactions has a consequential effect on one’s character traits. Hence, the heritability of personality isn’t always precisely 50%.

So, nature is the hereditary and genetic characteristics pre-determined at birth and influence a person’s behavior.

The Nurture Perspective

Nurture, in the context of the nature vs. nurture debate, is used to describe environmental factors that influence an individual’s development. 

According to Coon and Mitterer (2014), nurture:

“…refers to the sum of all external conditions that affect a person” (p. 100).

This includes a variety of influences such as parenting style, educational experiences, cultural background, and exposure to different environmental conditions over time.

While “nurture” may naturally invoke ideas of childhood and parental care, environmental components and life experience can shape human mental, emotional, and physical health throughout their lives (Harsha et al., 2020).

For example, lifestyle choices have been found to impact a person’s risk for developing certain diseases and their level of immunity against illness. 

Furthermore, addiction susceptibility can be impacted by environmental factors such as peer group that has been observed throughout an individual’s life (Ducci & Goldman, 2012).

Simply, nurture is an umbrella term for any environmental influences that shape the development of a person’s mental, physical, and emotional health. 

Examples of Nature vs Nurture

Nature examples.

• Eye color : A person’s eye color is determined by their genetic makeup and inherited from their parents.
• Height : As with eye color, height is a physical trait that is determined by a person’s genes and largely determines an individual’s adult height.
• Risk of D iseases : A person’s risk for developing certain diseases can be partially attributed to their genetic predisposition for that illness and influenced by lifestyle factors and personal environment.
• Immune S ystem F unctionality : Genetic predisposition plays an important role in determining an individual’s resistance to disease through the strength of their immune system. However, lifestyle choices can also influence this trait over time (e.g., diet and exercise).
• Hair Color: Hair color is determined by genetic factors. Recessive genes, like the red hair gene, generally have to be present in both parents for the recessive gene to become dominant.
• Balding: Going bald is an inherited trait. Some groups – such as male British Anglo-Saxons – are more likely to go bald in their 30s than the average.
• Adrenaline response : An individual’s ability to react quickly in dangerous situations—their “fight or flight” response—tends to be innate in all of us.

Nurture Examples

• Ethics and Parenting style : An individual’s upbringing and the parenting style they are exposed to can shape their behavior, emotional reactions, and psychological outlook throughout life.
• Linguistic Determinism Theory : In this theory, the language we are taught as a child will determine the ways we think and interact with the world. It goes some way to explaining how people of differing language groups may have differing values and belief systems .
• Values and Cultural background : Depending on their cultural background, different individuals may be exposed to different values and belief systems, which can impact their attitudes toward certain issues or topics/ideas/beliefs.
• Anxiety and Exposure to T rauma : Experiences with violence or traumatic events can have long-term effects on an individual’s psychology which could manifest outwardly as symptoms of anxiety or difficulty coping under pressure in later stages of life.
• Positivity and Social E nvironment : The people an individual interacts with can either positively or negatively affect their development. Individuals need to surround themselves with positive influences while avoiding those that might lead them down the wrong path in life.
• Relationship E xperiences and Sense of Security : Positive relationships throughout a person’s life will tend to improve outlook and well-being. In contrast, unhealthy relationships could leave long-term psychological damage that might need professional help before it can be addressed adequately by an individual suffering firsthand.

Nature and Nurture Examples

• Personality traits: The role of genetics (nature) in determining personality traits, such as extraversion or conscientiousness is balanced against the influence of upbringing and life experiences (nurture).
• Aggression: There is debate over whether aggressive behavior is primarily influenced by genetic factors (nature) or by environmental factors, such as upbringing, social learning , and exposure to violence (nurture).
• Athletic ability: The role of genetics (nature) determines a lot of our natural talent in sports but the importance of training, motivation, and exposure to physical activity (nurture) takes us the rest of the way.
• Musical talent: Musical ability may be affected by genetic predisposition (nature) but also environmental factors, such as exposure to music at a young age, education, and practice (nurture).
• Attachment styles: It is debatable whether a person’s attachment style (secure, anxious, or avoidant) is impacted by genetics (nature) versus the influence of early childhood experiences and caregiver relationships (nurture).
• Empathy and emotional intelligence: The capacity for empathy and emotional intelligence is debatably determined by both genetics (nature) and the result of upbringing, social exposure, and life experiences (nurture).
• Spiritual beliefs: Theological determinism holds that god has pre-selected his chosen people who will be true believers (nature) while others think that belief in god is a choice and we must raise our children to maintain a belief in god (nurture).
• Learning styles: In the 1980s, there was extensive debate over whether preferred learning styles, such as visual, auditory, or kinesthetic, are determined by genetic factors (nature) or influenced by educational experiences and personal development (nurture). Today, most education theorists believe that learning preferences are based on nurture over nature.
• Addiction susceptibility : Scientists have identified genes related to addiction susceptibility, even though this trait is also heavily influenced by the environment (Ducci & Goldman, 2012).
• Intelligence : Education can significantly impact traits such as intelligence levels and knowledge base, with certain experiences inspiring curiosity or creativity in individuals later in life.

Origins of Nature vs. Nurture Debate

The debate surrounding the extent to which human development is influenced by nature (heredity) or nurture (environmental factors) has been around since ancient times.

Plato, the renowned Greek philosopher, argued that beneficial traits in humans were attributable to both nature and nurture. He believed people could adapt to external occurrences throughout their lifetime (Englander, 2010).

However, his mentor Socrates leaned more towards genetics as the primary factor of human development – a notion known as Nativism, which was coined by both philosophers together.

In the late 1800s, Charles Darwin’s theory of evolution and Sir Francis Galton’s article “Hereditary Talent and Character” sparked a resurgence in interest in this topic (Galton, 1865)

So, Galton (1865) suggested hereditary influences to be at least as important as the environment when determining an individual’s outcomes in life.

The debate continued through subsequent decades, with psychologist John B. Watson’s revolutionary suggestion that environment—what he called “nurture”—was more important than hereditary factors or biology (Herrnstein, 1998).

In recent years, researchers have realized that both internal (genetic) and external (environmental) factors play a role in how individuals develop physically and psychologically. 

As such, most experts now subscribe to an approach that looks at how both genetic inheritance and environmental influences work together throughout life to shape each person’s unique character traits and behaviors.

The Role of Epigenetics in the Nature vs. Nurture Debate

Epigenetics is the study of changes in gene expression caused by environmental factors, such as diet and exposure to toxins, without altering the underlying sequences of DNA .

It is an emerging field of research that has been gaining prominence in recent years as scientists try to uncover how and to what extent the environment can shape genetic expression (Harvard University, 2019).

Epigenetic influences are now considered a significant factor in the nature vs. nurture debate, particularly in how individuals develop physically and psychologically throughout life. 

Evidence suggests that epigenetic mechanisms can be used to modulate gene expression depending on the environment, thus having a direct influence on an individual’s characteristics and behaviors (Harvard University, 2019).

This means that while both genetics and environment may play a role in determining an individual’s outcomes in life, epigenetics provides an additional layer of complexity by allowing environmental factors to interact with gene expression.

Nature vs. nurture is a decades-old debate that continues to be studied in various fields. 

Nativists state that genetics play a major role in determining characteristics and behaviors. For example, a person may have inherited certain traits from their family. 

However, empiricists suggest that external factors, such as upbringing and lifestyle choices, can also have a significant influence.

From ancient philosophers to modern-day scientists, this debate has gone through various iterations and continues to evolve today with the introduction of epigenetics. 

More recently, epigenetics have emerged as a key factor in the debate. Its  mechanisms can be used to modulate gene expression depending on the environment, thus having a direct influence on an individual.

So, it appears that both nature and nurture are important factors in determining an individual’s outcomes in life.

What Are Nature vs. Nurture Examples?

How is nature defined, how is nurture defined, the nature vs. nurture debate, nature vs. nurture examples, what is empiricism (extreme nurture position), contemporary views of nature vs. nurture.

Nature vs. nurture is an age-old debate about whether genetics (nature) plays a bigger role in determining a person's characteristics than lived experience and environmental factors (nurture). The term "nature vs. nature" was coined by English naturalist Charles Darwin's younger half-cousin, anthropologist Francis Galton, around 1875.

In psychology, the extreme nature position (nativism) proposes that intelligence and personality traits are inherited and determined only by genetics.

On the opposite end of the spectrum, the extreme nurture position (empiricism) asserts that the mind is a blank slate at birth; external factors like education and upbringing determine who someone becomes in adulthood and how their mind works. Both of these extreme positions have shortcomings and are antiquated.

This article explores the difference between nature and nurture. It gives nature vs. nurture examples and explains why outdated views of nativism and empiricism don't jibe with contemporary views.

In the context of nature vs. nurture, "nature" refers to genetics and heritable factors that are passed down to children from their biological parents.

Genes and hereditary factors determine many aspects of someone’s physical appearance and other individual characteristics, such as a genetically inherited predisposition for certain personality traits.

Scientists estimate that 20% to 60% percent of temperament is determined by genetics and that many (possibly thousands) of common gene variations combine to influence individual characteristics of temperament.

However, the impact of gene-environment (or nature-nurture) interactions on someone's traits is interwoven. Environmental factors also play a role in temperament by influencing gene activity. For example, in children raised in an adverse environment (such as child abuse or violence), genes that increase the risk of impulsive temperamental characteristics may be activated (turned on).

Trying to measure "nature vs. nurture" scientifically is challenging. It's impossible to know precisely where the influence of genes and environment begin or end.

How Are Inherited Traits Measured?

“Heritability”   describes the influence that genes have on human characteristics and traits. It's measured on a scale of 0.0 to 1.0. Very strong heritable traits like someone's eye color are ranked a 1.0.

Traits that have nothing to do with genetics, like speaking with a regional accent ranks a zero. Most human characteristics score between a 0.30 and 0.60 on the heritability scale, which reflects a blend of genetics (nature) and environmental (nurture) factors.

Thousands of years ago, ancient Greek philosophers like Plato believed that "innate knowledge" is present in our minds at birth. Every parent knows that babies are born with innate characteristics. Anecdotally, it may seem like a kid's "Big 5" personality traits (agreeableness, conscientiousness, extraversion, neuroticism, and openness) were predetermined before birth.

What is the "Big 5" personality traits

The Big 5 personality traits is a theory that describes the five basic dimensions of personality. It was developed in 1949 by D. W. Fiske and later expanded upon by other researchers and is used as a framework to study people's behavior.

From a "nature" perspective, the fact that every child has innate traits at birth supports Plato's philosophical ideas about innatism. However, personality isn't set in stone. Environmental "nurture" factors can change someone's predominant personality traits over time. For example, exposure to the chemical lead during childhood may alter personality.

In 2014, a meta-analysis of genetic and environmental influences on personality development across the human lifespan found that people change with age. Personality traits are relatively stable during early childhood but often change dramatically during adolescence and young adulthood.

It's impossible to know exactly how much "nurture" changes personality as people get older. In 2019, a study of how stable personality traits are from age 16 to 66 found that people's Big 5 traits are both stable and malleable (able to be molded). During the 50-year span from high school to retirement, some traits like agreeableness and conscientiousness tend to increase, while others appear to be set in stone.

Nurture refers to all of the external or environmental factors that affect human development such as how someone is raised, socioeconomic status, early childhood experiences, education, and daily habits.

Although the word "nurture" may conjure up images of babies and young children being cared for by loving parents, environmental factors and life experiences have an impact on our psychological and physical well-being across the human life span. In adulthood, "nurturing" oneself by making healthy lifestyle choices can offset certain genetic predispositions.

For example, a May 2022 study found that people with a high genetic risk of developing the brain disorder Alzheimer's disease can lower their odds of developing dementia (a group of symptoms that affect memory, thinking, and social abilities enough to affect daily life) by adopting these seven healthy habits in midlife:

• Staying active
• Healthy eating
• Losing weight
• Not smoking
• Reducing blood sugar
• Controlling cholesterol
• Maintaining healthy blood pressure

The nature vs. nurture debate centers around whether individual differences in behavioral traits and personality are caused primarily by nature or nurture. Early philosophers believed the genetic traits passed from parents to their children influence individual differences and traits. Other well-known philosophers believed the mind begins as a blank slate and that everything we are is determined by our experiences.

While early theories favored one factor over the other, experts today recognize there is a complex interaction between genetics and the environment and that both nature and nurture play a critical role in shaping who we are.

Eye color and skin pigmentation are examples of "nature" because they are present at birth and determined by inherited genes. Developmental delays due to toxins (such as exposure to lead as a child or exposure to drugs in utero) are examples of "nurture" because the environment can negatively impact learning and intelligence.

In Child Development

The nature vs. nurture debate in child development is apparent when studying language development. Nature theorists believe genetics plays a significant role in language development and that children are born with an instinctive ability that allows them to both learn and produce language.

Nurture theorists would argue that language develops by listening and imitating adults and other children.

In addition, nurture theorists believe people learn by observing the behavior of others. For example, contemporary psychologist Albert Bandura's social learning theory suggests that aggression is learned through observation and imitation.

In Psychology

In psychology, the nature vs. nurture beliefs vary depending on the branch of psychology.

• Biopsychology:  Researchers analyze how the brain, neurotransmitters, and other aspects of our biology influence our behaviors, thoughts, and feelings. emphasizing the role of nature.
• Social psychology: Researchers study how external factors such as peer pressure and social media influence behaviors, emphasizing the importance of nurture.
• Behaviorism: This theory of learning is based on the idea that our actions are shaped by our interactions with our environment.

In Personality Development

Whether nature or nurture plays a bigger role in personality development depends on different personality development theories.

• Behavioral theories: Our personality is a result of the interactions we have with our environment, such as parenting styles, cultural influences, and life experiences.
• Biological theories: Personality is mostly inherited which is demonstrated by a study in the 1990s that concluded identical twins reared apart tend to have more similar personalities than fraternal twins.
• Psychodynamic theories: Personality development involves both genetic predispositions and environmental factors and their interaction is complex.

In Mental Illness

Both nature and nurture can contribute to mental illness development.

For example, at least five mental health disorders are associated with some type of genetic component ( autism ,  attention-deficit hyperactivity disorder (ADHD) ,  bipolar disorder , major depression, and  schizophrenia ).

Other explanations for mental illness are environmental, such as:

• Being exposed to drugs or alcohol in utero 
• Witnessing a traumatic event, leading to post-traumatic stress disorder (PTSD)
• Adverse life events and chronic stress during childhood

In Mental Health Therapy

Mental health treatment can involve both nature and nurture. For example, a therapist may explore life experiences that may have contributed to mental illness development (nurture) as well as family history of mental illness (nature).

At the same time, research indicates that a person's genetic makeup may impact how their body responds to antidepressants. Taking this into consideration is important for finding the right treatment for each individual.

 What Is Nativism (Extreme Nature Position)?

Innatism emphasizes nature's role in shaping our minds and personality traits before birth. Nativism takes this one step further and proposes that all of people's mental and physical characteristics are inherited and predetermined at birth.

In its extreme form, concepts of nativism gave way to the early 20th century's racially-biased eugenics movement. Thankfully, "selective breeding," which is the idea that only certain people should reproduce in order to create chosen characteristics in offspring, and eugenics, arranged breeding, lost momentum during World War II. At that time, the Nazis' ethnic cleansing (killing people based on their ethnic or religious associations) atrocities were exposed.

Philosopher John Locke's tabula rasa theory from 1689 directly opposes the idea that we are born with innate knowledge. "Tabula rasa" means "blank slate" and implies that our minds do not have innate knowledge at birth.

Locke was an empiricist who believed that all the knowledge we gain in life comes from sensory experiences (using their senses to understand the world), education, and day-to-day encounters after being born.

Today, looking at nature vs. nature in black-and-white terms is considered a misguided dichotomy (two-part system). There are so many shades of gray where nature and nurture overlap. It's impossible to tease out how inherited traits and learned behaviors shape someone's unique characteristics or influence how their mind works.

The influences of nature and nurture in psychology are impossible to unravel. For example, imagine someone growing up in a household with an alcoholic parent who has frequent rage attacks. If that child goes on to develop a substance use disorder and has trouble with emotion regulation in adulthood, it's impossible to know precisely how much genetics (nature) or adverse childhood experiences (nurture) affected that individual's personality traits or issues with alcoholism.

Epigenetics Blurs the Line Between Nature and Nurture

"Epigenetics " means "on top of" genetics. It refers to external factors and experiences that turn genes "on" or "off." Epigenetic mechanisms alter DNA's physical structure in utero (in the womb) and across the human lifespan.

Epigenetics blurs the line between nature and nurture because it says that even after birth, our genetic material isn't set in stone; environmental factors can modify genes during one's lifetime. For example, cannabis exposure during critical windows of development can increase someone's risk of neuropsychiatric disease via epigenetic mechanisms.

Nature vs. nurture is a framework used to examine how genetics (nature) and environmental factors (nurture) influence human development and personality traits.

However, nature vs. nurture isn't a black-and-white issue; there are many shades of gray where the influence of nature and nurture overlap. It's impossible to disentangle how nature and nurture overlap; they are inextricably intertwined. In most cases, nature and nurture combine to make us who we are.

The Nature vs. Nurture Debate

Genetic and Environmental Influences and How They Interact

Verywell / Joshua Seong

• Definitions
• Interaction
• Contemporary Views

Nature refers to how genetics influence an individual's personality, whereas nurture refers to how their environment (including relationships and experiences) impacts their development. Whether nature or nurture plays a bigger role in personality and development is one of the oldest philosophical debates within the field of psychology .

Learn how each is defined, along with why the issue of nature vs. nurture continues to arise. We also share a few examples of when arguments on this topic typically occur, how the two factors interact with each other, and contemporary views that exist in the debate of nature vs. nurture as it stands today.

Nature and Nurture Defined

To better understand the nature vs. nurture argument, it helps to know what each of these terms means.

• Nature refers largely to our genetics . It includes the genes we are born with and other hereditary factors that can impact how our personality is formed and influence the way that we develop from childhood through adulthood.
• Nurture encompasses the environmental factors that impact who we are. This includes our early childhood experiences, the way we were raised , our social relationships, and the surrounding culture.

A few biologically determined characteristics include genetic diseases, eye color, hair color, and skin color. Other characteristics are tied to environmental influences, such as how a person behaves, which can be influenced by parenting styles and learned experiences.

For example, one child might learn through observation and reinforcement to say please and thank you. Another child might learn to behave aggressively by observing older children engage in violent behavior on the playground.

The Debate of Nature vs. Nurture

The nature vs. nurture debate centers on the contributions of genetics and environmental factors to human development. Some philosophers, such as Plato and Descartes, suggested that certain factors are inborn or occur naturally regardless of environmental influences.

Advocates of this point of view believe that all of our characteristics and behaviors are the result of evolution. They contend that genetic traits are handed down from parents to their children and influence the individual differences that make each person unique.

Other well-known thinkers, such as John Locke, believed in what is known as tabula rasa which suggests that the mind begins as a blank slate . According to this notion, everything that we are is determined by our experiences.

Behaviorism is a good example of a theory rooted in this belief as behaviorists feel that all actions and behaviors are the results of conditioning. Theorists such as John B. Watson believed that people could be trained to do and become anything, regardless of their genetic background.

People with extreme views are called nativists and empiricists. Nativists take the position that all or most behaviors and characteristics are the result of inheritance. Empiricists take the position that all or most behaviors and characteristics result from learning.

Examples of Nature vs. Nurture

One example of when the argument of nature vs. nurture arises is when a person achieves a high level of academic success . Did they do so because they are genetically predisposed to elevated levels of intelligence, or is their success a result of an enriched environment?

The argument of nature vs. nurture can also be made when it comes to why a person behaves in a certain way. If a man abuses his wife and kids, for instance, is it because he was born with violent tendencies, or is violence something he learned by observing others in his life when growing up?

Nature vs. Nurture in Psychology

Throughout the history of psychology , the debate of nature vs. nurture has continued to stir up controversy. Eugenics, for example, was a movement heavily influenced by the nativist approach.

Psychologist Francis Galton coined the terms 'nature versus nurture' and 'eugenics' and believed that intelligence resulted from genetics. Galton also felt that intelligent individuals should be encouraged to marry and have many children, while less intelligent individuals should be discouraged from reproducing.

The value placed on nature vs. nurture can even vary between the different branches of psychology , with some branches taking a more one-sided approach. In biopsychology , for example, researchers conduct studies exploring how neurotransmitters influence behavior, emphasizing the role of nature.

In social psychology , on the other hand, researchers might conduct studies looking at how external factors such as peer pressure and social media influence behaviors, stressing the importance of nurture. Behaviorism is another branch that focuses on the impact of the environment on behavior.

Nature vs. Nurture in Child Development

Some psychological theories of child development place more emphasis on nature and others focus more on nurture. An example of a nativist theory involving child development is Chomsky's concept of a language acquisition device (LAD). According to this theory, all children are born with an instinctive mental capacity that allows them to both learn and produce language.

An example of an empiricist child development theory is Albert Bandura's social learning theory . This theory says that people learn by observing the behavior of others. In his famous Bobo doll experiment , Bandura demonstrated that children could learn aggressive behaviors simply by observing another person acting aggressively.

Nature vs. Nurture in Personality Development

There is also some argument as to whether nature or nurture plays a bigger role in the development of one's personality. The answer to this question varies depending on which personality development theory you use.

According to behavioral theories, our personality is a result of the interactions we have with our environment, while biological theories suggest that personality is largely inherited. Then there are psychodynamic theories of personality that emphasize the impact of both.

Nature vs. Nurture in Mental Illness Development

One could argue that either nature or nurture contributes to mental health development. Some causes of mental illness fall on the nature side of the debate, including changes to or imbalances with chemicals in the brain. Genetics can also contribute to mental illness development, increasing one's risk of a certain disorder or disease.

Mental disorders with some type of genetic component include autism , attention-deficit hyperactivity disorder (ADHD), bipolar disorder , major depression , and schizophrenia .

Other explanations for mental illness are environmental. This includes being exposed to environmental toxins, such as drugs or alcohol, while still in utero. Certain life experiences can also influence mental illness development, such as witnessing a traumatic event, leading to the development of post-traumatic stress disorder (PTSD).

Nature vs. Nurture in Mental Health Therapy

Different types of mental health treatment can also rely more heavily on either nature or nurture in their treatment approach. One of the goals of many types of therapy is to uncover any life experiences that may have contributed to mental illness development (nurture).

However, genetics (nature) can play a role in treatment as well. For instance, research indicates that a person's genetic makeup can impact how their body responds to antidepressants. Taking this into consideration is important for getting that person the help they need.

Interaction Between Nature and Nurture

Which is stronger: nature or nurture? Many researchers consider the interaction between heredity and environment—nature with nurture as opposed to nature versus nurture—to be the most important influencing factor of all.

For example, perfect pitch is the ability to detect the pitch of a musical tone without any reference. Researchers have found that this ability tends to run in families and might be tied to a single gene. However, they've also discovered that possessing the gene is not enough as musical training during early childhood is needed for this inherited ability to manifest itself.

Height is another example of a trait influenced by an interaction between nature and nurture. A child might inherit the genes for height. However, if they grow up in a deprived environment where proper nourishment isn't received, they might never attain the height they could have had if they'd grown up in a healthier environment.

A newer field of study that aims to learn more about the interaction between genes and environment is epigenetics . Epigenetics seeks to explain how environment can impact the way in which genes are expressed.

Some characteristics are biologically determined, such as eye color, hair color, and skin color. Other things, like life expectancy and height, have a strong biological component but are also influenced by environmental factors and lifestyle.

Contemporary Views of Nature vs. Nurture

Most experts recognize that neither nature nor nurture is stronger than the other. Instead, both factors play a critical role in who we are and who we become. Not only that but nature and nurture interact with each other in important ways all throughout our lifespan.

As a result, many in this field are interested in seeing how genes modulate environmental influences and vice versa. At the same time, this debate of nature vs. nurture still rages on in some areas, such as in the origins of homosexuality and influences on intelligence .

While a few people take the extreme nativist or radical empiricist approach, the reality is that there is not a simple way to disentangle the multitude of forces that exist in personality and human development. Instead, these influences include genetic factors, environmental factors, and how each intermingles with the other.

The nature vs. nurture debate in psychology concerns the relative importance of an individual’s innate qualities (nature) versus personal experiences (nurture) in determining or causing individual differences in physical and behavioral traits. While early theories favored one factor over the other, contemporary views recognize a complex interplay between genes and environment in shaping behavior and development.

Key Takeaways

• Nature is what we think of as pre-wiring and is influenced by genetic inheritance and other biological factors.
• Nurture is generally taken as the influence of external factors after conception, e.g., the product of exposure, life experiences, and learning on an individual.
• Behavioral genetics has enabled psychology to quantify the relative contribution of nature and nurture concerning specific psychological traits.
• Instead of defending extreme nativist or nurturist views, most psychological researchers are now interested in investigating how nature and nurture interact in a host of qualitatively different ways.
• For example, epigenetics is an emerging area of research that shows how environmental influences affect the expression of genes.

The nature-nurture debate is concerned with the relative contribution that both influences make to human behavior, such as personality, cognitive traits, temperament and psychopathology.

Examples of Nature vs. Nurture

Nature vs. nurture in child development.

In child development, the nature vs. nurture debate is evident in the study of language acquisition . Researchers like Chomsky (1957) argue that humans are born with an innate capacity for language (nature), known as universal grammar, suggesting that genetics play a significant role in language development.

Conversely, the behaviorist perspective, exemplified by Skinner (1957), emphasizes the role of environmental reinforcement and learning (nurture) in language acquisition.

Twin studies have provided valuable insights into this debate, demonstrating that identical twins raised apart may share linguistic similarities despite different environments, suggesting a strong genetic influence (Bouchard, 1979)

However, environmental factors, such as exposure to language-rich environments, also play a crucial role in language development, highlighting the intricate interplay between nature and nurture in child development.

Nature vs. Nurture in Personality Development

The nature vs. nurture debate in personality psychology centers on the origins of personality traits. Twin studies have shown that identical twins reared apart tend to have more similar personalities than fraternal twins, indicating a genetic component to personality (Bouchard, 1994).

However, environmental factors, such as parenting styles, cultural influences, and life experiences, also shape personality.

For example, research by Caspi et al. (2003) demonstrated that a particular gene (MAOA) can interact with childhood maltreatment to increase the risk of aggressive behavior in adulthood.

This highlights that genetic predispositions and environmental factors contribute to personality development, and their interaction is complex and multifaceted.

Nature vs. Nurture in Mental Illness Development

The nature vs. nurture debate in mental health explores the etiology of depression. Genetic studies have identified specific genes associated with an increased vulnerability to depression, indicating a genetic component (Sullivan et al., 2000).

However, environmental factors, such as adverse life events and chronic stress during childhood, also play a significant role in the development of depressive disorders (Dube et al.., 2002; Keller et al., 2007)

The diathesis-stress model posits that individuals inherit a genetic predisposition (diathesis) to a disorder, which is then activated or exacerbated by environmental stressors (Monroe & Simons, 1991).

This model illustrates how nature and nurture interact to influence mental health outcomes.

Nature vs. Nurture of Intelligence

The nature vs. nurture debate in intelligence examines the relative contributions of genetic and environmental factors to cognitive abilities.

Intelligence is highly heritable, with about 50% of variance in IQ attributed to genetic factors, based on studies of twins, adoptees, and families (Plomin & Spinath, 2004).

Heritability of intelligence increases with age, from about 20% in infancy to as high as 80% in adulthood, suggesting amplifying effects of genes over time.

However, environmental influences, such as access to quality education and stimulating environments, also significantly impact intelligence.

Shared environmental influences like family background are more influential in childhood, whereas non-shared experiences are more important later in life.

Research by Flynn (1987) showed that average IQ scores have increased over generations, suggesting that environmental improvements, known as the Flynn effect , can lead to substantial gains in cognitive abilities.

Molecular genetics provides tools to identify specific genes and understand their pathways and interactions. However, progress has been slow for complex traits like intelligence. Identified genes have small effect sizes (Plomin & Spinath, 2004).

Overall, intelligence results from complex interplay between genes and environment over development. Molecular genetics offers promise to clarify these mechanisms. The nature vs nurture debate is outdated – both play key roles.

Nativism (Extreme Nature Position)

It has long been known that certain physical characteristics are biologically determined by genetic inheritance.

Color of eyes, straight or curly hair, pigmentation of the skin, and certain diseases (such as Huntingdon’s chorea) are all a function of the genes we inherit.

These facts have led many to speculate as to whether psychological characteristics such as behavioral tendencies, personality attributes, and mental abilities are also “wired in” before we are even born.

Those who adopt an extreme hereditary position are known as nativists.  Their basic assumption is that the characteristics of the human species as a whole are a product of evolution and that individual differences are due to each person’s unique genetic code.

In general, the earlier a particular ability appears, the more likely it is to be under the influence of genetic factors. Estimates of genetic influence are called heritability.

Examples of extreme nature positions in psychology include Chomsky (1965), who proposed language is gained through the use of an innate language acquisition device. Another example of nature is Freud’s theory of aggression as being an innate drive (called Thanatos).

Characteristics and differences that are not observable at birth, but which emerge later in life, are regarded as the product of maturation. That is to say, we all have an inner “biological clock” which switches on (or off) types of behavior in a pre-programmed way.

The classic example of the way this affects our physical development are the bodily changes that occur in early adolescence at puberty.

However, nativists also argue that maturation governs the emergence of attachment in infancy , language acquisition , and even cognitive development .

Empiricism (Extreme Nurture Position)

At the other end of the spectrum are the environmentalists – also known as empiricists (not to be confused with the other empirical/scientific  approach ).

Their basic assumption is that at birth, the human mind is a tabula rasa (a blank slate) and that this is gradually “filled” as a result of experience (e.g., behaviorism ).

From this point of view, psychological characteristics and behavioral differences that emerge through infancy and childhood are the results of learning.  It is how you are brought up (nurture) that governs the psychologically significant aspects of child development and the concept of maturation applies only to the biological.

For example, Bandura’s (1977) social learning theory states that aggression is learned from the environment through observation and imitation. This is seen in his famous bobo doll experiment (Bandura, 1961).

Also, Skinner (1957) believed that language is learned from other people via behavior-shaping techniques.

Evidence for Nature

• Biological Approach
• Biology of Gender
• Medical Model

Freud (1905) stated that events in our childhood have a great influence on our adult lives, shaping our personality.

He thought that parenting is of primary importance to a child’s development , and the family as the most important feature of nurture was a common theme throughout twentieth-century psychology (which was dominated by environmentalists’ theories).

Behavioral Genetics

Researchers in the field of behavioral genetics study variation in behavior as it is affected by genes, which are the units of heredity passed down from parents to offspring.

“We now know that DNA differences are the major systematic source of psychological differences between us. Environmental effects are important but what we have learned in recent years is that they are mostly random – unsystematic and unstable – which means that we cannot do much about them.” Plomin (2018, xii)

Behavioral genetics has enabled psychology to quantify the relative contribution of nature and nurture with regard to specific psychological traits. One way to do this is to study relatives who share the same genes (nature) but a different environment (nurture). Adoption acts as a natural experiment which allows researchers to do this.

Empirical studies have consistently shown that adoptive children show greater resemblance to their biological parents, rather than their adoptive, or environmental parents (Plomin & DeFries, 1983; 1985).

Another way of studying heredity is by comparing the behavior of twins, who can either be identical (sharing the same genes) or non-identical (sharing 50% of genes). Like adoption studies, twin studies support the first rule of behavior genetics; that psychological traits are extremely heritable, about 50% on average.

The Twins in Early Development Study (TEDS) revealed correlations between twins on a range of behavioral traits, such as personality (empathy and hyperactivity) and components of reading such as phonetics (Haworth, Davis, Plomin, 2013; Oliver & Plomin, 2007; Trouton, Spinath, & Plomin, 2002).

Implications

Jenson (1969) found that the average I.Q. scores of black Americans were significantly lower than whites he went on to argue that genetic factors were mainly responsible – even going so far as to suggest that intelligence is 80% inherited.

The storm of controversy that developed around Jenson’s claims was not mainly due to logical and empirical weaknesses in his argument. It was more to do with the social and political implications that are often drawn from research that claims to demonstrate natural inequalities between social groups.

For many environmentalists, there is a barely disguised right-wing agenda behind the work of the behavioral geneticists.  In their view, part of the difference in the I.Q. scores of different ethnic groups are due to inbuilt biases in the methods of testing.

More fundamentally, they believe that differences in intellectual ability are a product of social inequalities in access to material resources and opportunities.  To put it simply children brought up in the ghetto tend to score lower on tests because they are denied the same life chances as more privileged members of society.

Now we can see why the nature-nurture debate has become such a hotly contested issue.  What begins as an attempt to understand the causes of behavioral differences often develops into a politically motivated dispute about distributive justice and power in society.

What’s more, this doesn’t only apply to the debate over I.Q.  It is equally relevant to the psychology of sex and gender , where the question of how much of the (alleged) differences in male and female behavior is due to biology and how much to culture is just as controversial.

Polygenic Inheritance

Rather than the presence or absence of single genes being the determining factor that accounts for psychological traits, behavioral genetics has demonstrated that multiple genes – often thousands, collectively contribute to specific behaviors.

Thus, psychological traits follow a polygenic mode of inheritance (as opposed to being determined by a single gene). Depression is a good example of a polygenic trait, which is thought to be influenced by around 1000 genes (Plomin, 2018).

This means a person with a lower number of these genes (under 500) would have a lower risk of experiencing depression than someone with a higher number.

While still limited in predictive power, polygenic risk scores provide a way to quantify innate genetic risk, allowing researchers to study how this interacts with environmental factors to influence outcomes.

The high polygenicity of psychiatric disorders (many genes each contributing small effects) revealed by genetic architecture studies shows that there isn’t a simple genetic determinism for most psychiatric conditions. 

This complexity is further increased when you consider how these genes might interact with each other (epistasis) and with environmental factors. The same genetic profile might lead to different outcomes in different environments.

The Nature of Nurture

Nurture assumes that correlations between environmental factors and psychological outcomes are caused environmentally. For example, how much parents read with their children and how well children learn to read appear to be related. Other examples include environmental stress and its effect on depression.

However, behavioral genetics argues that what look like environmental effects are to a large extent really a reflection of genetic differences (Plomin & Bergeman, 1991).

People select, modify and create environments correlated with their genetic disposition. This means that what sometimes appears to be an environmental influence (nurture) is a genetic influence (nature).

So, children that are genetically predisposed to be competent readers, will be happy to listen to their parents read them stories, and be more likely to encourage this interaction.

Interaction Effects

However, in recent years there has been a growing realization that the question of “how much” behavior is due to heredity and “how much” to the environment may itself be the wrong question.

Take intelligence as an example. Like almost all types of human behavior, it is a complex, many-sided phenomenon which reveals itself (or not!) in a great variety of ways.

The “how much” question assumes that psychological traits can all be expressed numerically and that the issue can be resolved in a quantitative manner.

Heritability statistics revealed by behavioral genetic studies have been criticized as meaningless, mainly because biologists have established that genes cannot influence development independently of environmental factors; genetic and nongenetic factors always cooperate to build traits. The reality is that nature and culture interact in a host of qualitatively different ways (Gottlieb, 2007; Johnston & Edwards, 2002).

Instead of defending extreme nativist or nurturist views, most psychological researchers are now interested in investigating how nature and nurture interact.

For example, in psychopathology , this means that both a genetic predisposition and an appropriate environmental trigger are required for a mental disorder to develop. For example, epigenetics state that environmental influences affect the expression of genes.

What is Epigenetics?

Epigenetics is the term used to describe inheritance by mechanisms other than through the DNA sequence of genes. For example, features of a person’s physical and social environment can effect which genes are switched-on, or “expressed”, rather than the DNA sequence of the genes themselves.

Epigenetics refers to changes in gene expression that don’t involve alterations to the DNA sequence itself. Instead, these changes affect how genes are read and translated into proteins.

Mechanisms of Epigenetic Modification

Epigenetic modifications provide a direct biological mechanism by which environmental experiences (nurture) can alter how our genes (nature) function. This challenges the idea of genes as a fixed, unchangeable blueprint.

Epigenetic changes can occur throughout life, but certain periods (like early development or adolescence) may be particularly sensitive to these modifications.

There are several ways epigenetic changes can occur:

• DNA methylation : Adding methyl groups to DNA, typically suppressing gene expression.
• Histone modification : Changes to the proteins that DNA wraps around, affecting how tightly or loosely genes are packaged.
• Non-coding RNA : RNA molecules that can regulate gene expression.

Environmental Stressors

Environmental stressors have been shown to induce epigenetic changes, with substantial evidence from both animal and human studies (Klengel et al., 2016).

These stressors can include malnutrition, exposure to toxins, extreme stress, or trauma, leading to alterations in DNA methylation patterns, histone modifications, and changes in non-coding RNA expression (Bale, 2015).

Transgenerational Epigenetic Inheritance

Some epigenetic modifications may be passed down to future generations, suggesting that environmental influences on one generation could affect the genetic expression of subsequent generations.

One such example is what is known as the Dutch Hunger Winter, during last year of the Second World War. What they found was that children who were in the womb during the famine experienced a life-long increase in their chances of developing various health problems compared to children conceived after the famine.

Epigenetic effects can sometimes be passed from one generation to the next, although the effects only seem to last for a few generations. There is some evidence that the effects of the Dutch Hunger Winter affected grandchildren of women who were pregnant during the famine.

Therefore, it makes more sense to say that the difference between two people’s behavior is mostly due to hereditary factors or mostly due to environmental factors.

This realization is especially important given the recent advances in genetics, such as polygenic testing.  The Human Genome Project, for example, has stimulated enormous interest in tracing types of behavior to particular strands of DNA located on specific chromosomes.

If these advances are not to be abused, then there will need to be a more general understanding of the fact that biology interacts with both the cultural context and the personal choices that people make about how they want to live their lives.

There is no neat and simple way of unraveling these qualitatively different and reciprocal influences on human behavior.

The Concept of “Memories” Being Passed Down

While there’s evidence that environmental stressors can induce epigenetic changes that might affect future generations, the concept of specific “memories” being passed down is not supported by current scientific evidence.

This concept often stems from misinterpretation of studies showing behavioral or physiological changes in offspring related to parental experiences.

Some animal studies have demonstrated that offspring of stressed parents exhibit altered stress responses or behavioral changes.

For example, Dias and Ressler (2014) showed in mice that fear responses to specific odors can be passed down to subsequent generations. However, these are not “memories” in the conventional sense, but rather alterations in stress response systems or sensory sensitivities.

Human studies in this area are much more complex and limited. Research has examined children of trauma survivors (e.g., Holocaust survivors, 9/11 survivors) and found differences in stress hormone levels or risk for PTSD (Yehuda et al., 2016).

However, these studies face significant challenges in separating genetic, epigenetic, and social/cultural factors.

The challenges in interpreting human studies are substantial. Humans have complex social structures and cultural transmission of information, making it often impossible to separate the effects of biological inheritance from social learning and shared environments (Heard & Martienssen, 2014).

The longer lifespan and generation time in humans also make it challenging to study transgenerational effects. What’s often observed is not the transmission of specific memories, but rather altered predispositions or sensitivities.

For example, children of trauma survivors might have an altered stress response system, making them more sensitive to stress, but they don’t inherit specific memories of the trauma (Bowers & Yehuda, 2016).

While specific memories aren’t passed down, changes in gene expression related to stress response systems could potentially be inherited. These could affect how future generations respond to stress or process sensory information (Zannas et al., 2015).

Epigenetics: Licking Rat Pups

Michael Meaney and his colleagues at McGill University in Montreal, Canada conducted the landmark epigenetic study on mother rats licking and grooming their pups.

This research found that the amount of licking and grooming received by rat pups during their early life could alter their epigenetic marks and influence their stress responses in adulthood.

Pups that received high levels of maternal care (i.e., more licking and grooming) had a reduced stress response compared to those that received low levels of maternal care.

Meaney’s work with rat maternal behavior and its epigenetic effects has provided significant insights into the understanding of early-life experiences, gene expression, and adult behavior.

It underscores the importance of the early-life environment and its long-term impacts on an individual’s mental health and stress resilience.

Epigenetics: The Agouti Mouse Study

Waterland and Jirtle’s 2003 study on the Agouti mouse is another foundational work in the field of epigenetics that demonstrated how nutritional factors during early development can result in epigenetic changes that have long-lasting effects on phenotype.

In this study, they focused on a specific gene in mice called the Agouti viable yellow (A^vy) gene. Mice with this gene can express a range of coat colors, from yellow to mottled to brown.

This variation in coat color is related to the methylation status of the A^vy gene: higher methylation is associated with the brown coat, and lower methylation with the yellow coat.

Importantly, the coat color is also associated with health outcomes, with yellow mice being more prone to obesity, diabetes, and tumorigenesis compared to brown mice.

Waterland and Jirtle set out to investigate whether maternal diet, specifically supplementation with methyl donors like folic acid, choline, betaine, and vitamin B12, during pregnancy could influence the methylation status of the A^vy gene in offspring.

Key findings from the study include:

Dietary Influence : When pregnant mice were fed a diet supplemented with methyl donors, their offspring had an increased likelihood of having the brown coat color. This indicated that the supplemented diet led to an increased methylation of the A^vy gene.

Health Outcomes : Along with the coat color change, these mice also had reduced risks of obesity and other health issues associated with the yellow phenotype.

Transgenerational Effects : The study showed that nutritional interventions could have effects that extend beyond the individual, affecting the phenotype of the offspring.

The implications of this research are profound. It highlights how maternal nutrition during critical developmental periods can have lasting effects on offspring through epigenetic modifications, potentially affecting health outcomes much later in life.

The study also offers insights into how dietary and environmental factors might contribute to disease susceptibility in humans.

Challenges in Epigenetic Research:

• Epigenetic changes can be tissue-specific, making it challenging to study in the living human brain
• The causal direction (whether epigenetic changes cause disorders or result from them) is often unclear
• The complexity of interactions between multiple epigenetic mechanisms and genetic variants

What does nature refer to in the nature vs. nurture debate?

In the nature vs. nurture debate, “nature” refers to the influence of genetics, innate qualities, and biological factors on human development, behavior, and traits. It emphasizes the role of hereditary factors in shaping who we are.

What does nurture refer to in the nature vs. nurture debate?

In the nature vs. nurture debate, “nurture” refers to the influence of the environment, upbringing, experiences, and social factors on human development, behavior, and traits. It emphasizes the role of external factors in shaping who we are.

Why is it important to determine the contribution of heredity (nature) and environment (nurture) in human development?

Determining the contribution of heredity and environment in human development is crucial for understanding the complex interplay between genetic factors and environmental influences. It helps identify the relative significance of each factor, informing interventions, policies, and strategies to optimize human potential and address developmental challenges.

Nature vs. Nurture Debate: What Really Matters in Psychology

Is your life and personality shaped by your genes or environment? This is the big question of the nature vs. nurture debate, science has the answer.

Subscribe to our weekly newsletter

Are you simply a product of your environment, or do your genes have the final say? This is the ultimate question of the nature vs. nurture debate. Take a deep dive into the origins of the debate, and learn how epigenetics has upended the argument once and for all.

What is Nature vs. Nurture?

Nature vs. nurture can be defined as the difference between the genetics that people inherit (nature) vs. the environmental influences that accumulate over a lifetime (nurture). For years, many people have believed that nature rules supreme and reject the idea that environment or parenting has a large role in shaping people. 

The big question in the debate is this––how much of a person’s personality is a result of genes, and how much is related to environment and experiences? People have been arguing about this for years for political, personal, and social reasons. 

So, what’s the answer…are we shaped by nature or nurture? The answer is both, and it depends on which traits. Read on for the science of nature or nurture below.

Examples of Nature vs. Nurture

Let’s look at some examples to see how nature and nurture impact a person’s development. 

Examples of Nature Impacting Human Development:

• Genetically predisposed to be tall.
• Inherited red hair and blue eyes from the maternal side of the family.
• ADHD, when it appears together with conduct disorder, is attributed to genes 1 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3303131/ .
• Genes contribute to genetic disorders such as Edwards syndrome, Patau syndrome, and Warkany syndrome.
• Anxiety and depression occurring together 1 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3303131/ are considered to be connected to a genetic predisposition.

Examples of Nurture Impacting Human Development:

• The mother experienced high amounts of prenatal stress 2 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9676865/#:~:text=Overall%2C%20maternal%20anxiety%20and%20depression,2017%3B%20Takegata%20et%20al.%2C , contributing to a fearful personality in the child, who is likely to express positive emotions. 
• Lack of healthy attachment to the caregiver impacts relationships with others throughout life.
• Growing up malnourished 3 https://www.frontiersin.org/articles/10.3389/fpsyg.2019.01886/full can stunt height and contribute to obesity.
• A supportive community environment 4 https://digitalscholarship.unlv.edu/cgi/viewcontent.cgi?article=1583&context=jhdrp contributed to feelings of confidence and the ability to succeed.
• Growing up during political instability causes heightened aggression and revenge-seeking 5 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3712526/#:~:text=There%20is%20now%20convincing%20documentation,disorders%2C%20fear%20and%20panic%2C%20poor later in life. 

How Has Nature vs. Nurture Changed Over Time? 

Nature vs. nurture has changed in many ways, perhaps the most significant change being the understanding of nurture. Early developmentalists saw nurture as the care given to the child by their parents (usually with an emphasis on the mother). Today scientists continue to discover that nurture includes many environmental influences––from prenatal to end-of-life. 

While the nature vs. nurture debate was once hotly disputed, most human developmentalists agree that both nature and nurture have a hand in shaping individuals. 

What you should know: The study of epigenetics 6 https://developingchild.harvard.edu/resources/what-is-epigenetics-and-how-does-it-relate-to-child-development/ has changed the nature vs. nurture debate landscape. Genes are not static but are impacted by nurture (environment), making it possible to change and override gene expression. 

We’ll get to even more examples below, but let’s look at a couple of scenarios of how nurture can impact genes.

Scenario 1: You are genetically predisposed to obesity, but your mom had excellent dietary health during pregnancy; this impacts your epigenome 7 https://ehp.niehs.nih.gov/doi/10.1289/ehp.8700?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed , reducing the risk for obesity and increasing your lifespan. 

Scenario 2: In early childhood, you have several negative experiences that deeply impact you. These experiences have the ability to override your natural gene expression 8 https://www.sciencedirect.com/science/article/abs/pii/S0306452212003028?via%3Dihub and “increase the risk not only for poor physical and mental health outcomes but also for impairments in future learning capacity and behavior.”

Everything from social interactions to diet to air quality can impact how genes interact and are expressed. 

“Contrary to popular belief, the genes inherited from one’s parents do not set a child’s future development in stone.” — Harvard Center on the Developing Child

The question, as we’ll see, isn’t nature or nurture, but rather nature and nurture. 

What Does Nature vs. Nurture Have to Do With Psychology, Sociology, and Genetics?

The nature vs. nurture debate has both been influenced by and has influenced psychology, sociology, and genetics. 

• Psychology is largely concerned with the mind and behavior of the individual.
• Sociology is concerned with the collective experiences and behavior of society.
• Genetics studies how genes and traits are passed down through families. 

Ultimately, all three are concerned with studying how and why people behave the way they do. But this isn’t just about behavior; nature vs. nurture has been extensively studied in relation to the body. Scientists want to know how genes and the environment impact everything from low back pain 9 https://pubmed.ncbi.nlm.nih.gov/23335362/ to obesity 10 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3224976/ . 

Let’s dive deeper so you can decide for yourself how much nature or nurture may have had a hand in shaping your own personality. 

How To Set Better Goals Using Science

Do you set the same goals over and over again? If you’re not achieving your goals – it’s not your fault! Let me show you the science-based goal-setting framework to help you achieve your biggest goals.

Who Came Up With Nature vs. Nurture?

Sir Francis Galton is credited with first coining the nature vs. nurture phrase. To better understand the beginning of the nature vs. nurture debate, we have to go back to the 1800s to look at why Galton came up with “nature vs. nurture” in the first place. Hold on because it’s not pretty.

Galton was a particularly unlikable anthropologist who gave us fingerprinting (great!) and invented eugenics (why was he knighted?). 

He sought to defend his beliefs with science and set out to prove that nature, not nurture, determined the intelligence and “excellence” of a person 11 https://galton.org/books/hereditary-genius/ . His cousin, Darwin, gave his stamp of approval on the “capital account” 12 https://galton.org/letters/darwin/correspondence.htm given by Galton in his book, Hereditary Genius 13 https://galton.org/books/hereditary-genius/text/v5/galton-1869-hereditary-genius-v5.htm#_Toc68688332 . 

In the book, Galton used the nature over nurture argument to propose and legitimize the ultimate elimination of criminals, “worthless” individuals, and “inferior” races (including Africans, Australians, Jews, working-class women in London, etc.) by controlling who could procreate and who couldn’t.  

While it’s unfortunate Galton had such a negative impact on science, it provides important context. Understanding where the debate originated helps us understand the ethical implications of how an unbalanced view of nature has been used to justify ongoing injustice both in policymaking and the treatment of individuals. 

Even though the argument for nature had a sordid start, let’s not throw it out completely! There is a lot we can learn about  ourselves, as both nature and nurture have a hand in shaping who we are. 

How Nature and Nurture Impact Human Development & Personality

Most developmentalists believe each person is unique and responds to a situation or experience based on many factors. As you try to understand the impact of nature and nurture on yourself or others, please remember while human development is a refined science, people are not computers. People can, and often do, defy the expectations of science, either becoming more or less resilient in the face of challenges. 

How Nature Impacts Personality

Now remember, nature involves the genetics that impact a person’s development and personality. Studies have found a person’s genes impact 30-60% of personality 14 https://www.nature.com/articles/s41380-018-0263-6 . If this sounds like a broad range, it is! But, we must consider all the variables that interact with a person’s genes. 

• A number of studies 15 https://journals.sagepub.com/doi/10.1111/j.0963-7214.2004.00295.x have found a connection between genetics and emotional well-being. 
• While personality seems to be heritable, to some extent, researchers are still trying to understand the actual “genetic basis of personality 16 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7012279/ .”

What this really means: Researchers would like to attribute personality traits like neuroticism or extroversion to a specific gene in your body, but, at the end of the day, they can’t. Studies have linked genetics with certain behavior and traits, but studies are often difficult to replicate 16 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7012279/ and may have gaps in the research. Nature clearly impacts a person, but science isn’t as hard and fast as some might think. 

Watch our video below to learn what type of personality you have:

How Nurture Impacts Personality

Remember the variables we mentioned that impact nature? Those variables are largely introduced by nurture. Here are some examples of how nurture can impact personality. 

• Maternal stress during pregnancy 17 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5052760/ has been found to increase the child’s stress. This, in turn, impacts the temperament of the child 18 https://srcd.onlinelibrary.wiley.com/doi/abs/10.1111/j.1467-8624.1995.tb00851.x . 
• A study in Germany 19 https://pubmed.ncbi.nlm.nih.gov/22275337/ found that military training decreased agreeableness in personalities, and this change persisted even after a person left the military and re-entered the workforce.  
• Social expectations create the most profound personality changes 20 https://pubmed.ncbi.nlm.nih.gov/21859226/ in the young and the elderly. 
• Food insecurity harmfully impacts mental health 21 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7282962/ , causing everything from anxiety to maternal depression. Interestingly, food insecurity also increases the risk of obesity 3 https://www.frontiersin.org/articles/10.3389/fpsyg.2019.01886/full . 

As you can see, nurture isn’t just how much a mother holds and comforts her baby! This is a limited view of nurture when in reality, there are so many external factors involved. The psychologist Urie Bronfenbrenner identified six key ecological systems that profoundly impact a person. All of these systems are an element of nurture. 

• Microsystem: Immediate social relationships, including family and peers.  
• Exosystem: Local institutions such as school, churches, temples, mosques, etc.
• Macrosystem: The larger setting that a person inhabits, such as culture, economics, and politics, creates a sense of shared beliefs and expectations of behavior. 
• Mesosystem: How other systems are interconnected.
• Chronosystem: The historical context that a person lives in, including values, events, technologies, and birth cohort (e.g., Boomer, Gen X, Millennial, Gen Z).
• Bioecological: The internal biology of a person. 

The ecological systems don’t just impact a person during childhood development. Psychology recognizes that people change through all phases of life! Personality is not set in stone 22 https://pubmed.ncbi.nlm.nih.gov/12757147/ . As a person ages and lives in various environments, this impacts how the person experiences the world around them. 

“In the real world, there is no nature vs. nurture argument, only an infinitely complex and moment-by-moment interaction between genetic and environmental effects” — Gabor Maté, Physician and Author

Can You Change Your Genes? 

At the end of the day, your genes (nature) are directly impacted by your environment (nurture). This means you have the power to change your genes! 

If that doesn’t make sense and you’re still wondering which is more important––nature or nurture, the delightful world of epigenetics has the answers. Let’s start with this beautifully explained infographic from Harvard 6 https://developingchild.harvard.edu/resources/what-is-epigenetics-and-how-does-it-relate-to-child-development/ .

Image: Harvard Center on the Developing Child

Essentially, epigenetics put to rest the old question of whether nature or nurture is more important in shaping identity and personality. Because of how epigenetics work in your body, nature, and nurture have a symbiotic relationship––one impacting the other and creating an ebb and flow in personality. 

You can change your genes by changing your behavior and your environment. 

Pro Tip: Studies have found you can begin to modify your epigenetic patterns 23 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3752894/ when you…

• Adjust your diet
• Add in physical exercise
• Reduce alcohol consumption
• Remove tobacco
• Limit exposure to environmental pollutants
• Learn to manage stress
• Avoid working night shifts 
• Have supportive, safe relationships

How Nature and Nurture Impacted Your Own Development

As you think about how nature and nurture have impacted you, we encourage you to reflect on your experiences both in the past and the present. Think about the experiences of your parents. What was it like for your mom when she was pregnant with you, the environment you grew up in, and where you find yourself today? 

Your life is an intricate story woven with tiny threads of your experiences, the experiences of your environment and community, and the experiences of your ancestors. The past had a hand in shaping the person you are today, but you have the amazing ability to change the direction of who you will become. 

The Highlights:

• Inherited genes may impact things like height, personality, and health.
• Experiences and environment impact how genes are activated and released. This is epigenetics and impacts everything from what triggers you to how you respond in social situations. 
• Safe relationships and supportive environments can positively impact the epigenome. 
• As much as possible, choose to be in positive environments. Surrounding yourself with beauty, clean air, nature, and healthy relationships builds your capacity for change. 

As you identify the areas of your life that you’d like to improve or change, emotional intelligence is an excellent place to start. This is a skill that will help you connect with yourself and others. Check out our article on 10 Emotional Intelligence Traits to Master for Self-Growth .

Nature Versus Nurture Essays

1. introduction.

The question of how nature and nurture interact to influence human development has been a question of interest to virtually all genetic and developmental researchers. Indeed, the question of how much of human development is due to either heredity, environment, or the interplay of both factors has generated significant debate, particularly in light of new discoveries about the genetic side of the equation. With the mapping of the human genome and the development of other new and powerful genetic technologies, researchers have advanced dozens of hypotheses about just how much of all human traits are strictly under genetic control (and thus should be "immune" to change), how much of human traits are modulated by the environment (both physical and social), and the variety of other thinking about the nature and nurture issue (e.g., the relationship of genes to early emerging traits). The current volume emphasizes the growing acceptance that in reality, nature and nurture are constantly interacting with one another to shape the course of human development. Indeed, the kinds of questions about nature and nurture and their interaction that are currently being addressed are fundamentally different from those that were even conceivable to address only a few years earlier. For example, the focus of the papers included in this volume range from considering questions that are primarily methodological in nature (e.g. What was the relative contribution of the Sex Chromosome genes versus the Autosomal genes involved in sex-biased changes in children's personality?) all the way to those that focus on the nature and nurture of different types of traits (e.g. Is there something special about the genetic component of personality development?). As a result, the various authors provide a perspective on the "yin and yang" of nature and nurture that spans a range of different thinking about how nature and nurture are related.

1.1. Background of the Nature Versus Nurture Debate

The nature versus nurture debate, which has an ancient history, continues with contemporary psychologists, medical scientists, and biologists studying not only health outcomes but also environmental and genetic factors affecting health. It is no longer a debate about the choice or necessity of one or the other but an acceptance of the fact that many health outcomes are due to the interplay between genetic and environmental factors. Among the earliest documented recorded historical debates of nature versus nurture is seen during the time of the ancient Greeks. Education Philosophy, a well-known book by Plato, discusses the nature versus nurture debate and provides societal entitlement and environmentalist views on the nature versus nurture debate. A similar debate about choice/nature and nurture/fate can be distinguished in many other regional cultures including Chinese, Indian, Islamic, and Near East societies. Archaeological evidence of Blombos cave indicates that early humans had significant aesthetic ability and that stone tools used in this time period were being made differently. In 1857, Charles Darwin started his On the Origin of Species book, the premise of which is governed by the ideas of adaptation of species to different environments and the acquisition of characteristics that are inherited by the descendants. During the 19th century, the idea of environmentalism took various forms and also has been applied to the fields of anthropology and sociology.

1.2. Purpose and Scope of the Essays

The central aim of this dissertation is to examine, through the use of behavioral genetic methods and molecular genetic methods, how the environment moderates genetic influence on behavior. Of particular interest are differences in genetic influence on behavior across levels of a putative environmental moderator. These questions are explored in three separate papers. In this introductory chapter, the purpose and main ideas of each paper are presented. The first essay (Chapter 2) evaluates and meta-analytically reviews G × E interaction studies in behavioral genetics. A directory of quantitative G × E interaction research from 1997 to 2003 conducted with humans was assembled. Results from the statistical interaction tests were archived, and the relationships between the types of genetic influences examined, variables used as proxies for environmental differences, and the methodological characteristics of the studies were assessed. In the meta-analysis, the mean effect sizes were found to vary across the three types of G × E hypotheses, and these findings provide initial directions for future research. Additionally, the effect coded for the results of G × E interaction studies, the methodological attributes of the research and, in many cases, the broader theoretical concern that relative environmental theoretical difference might be placing on behavior, are discussed.

2. Theoretical Frameworks

In Part I, we explore a number of researches that provide the background for the ideas presented in this book. For researchers, practitioners, and updating readers, research literature, research tools, and material offering historical perspective are primary sources. It is hoped that as these essays evolved through the research process, the groundwork supporting the theory lent a depth and sophistication not characteristic of other debates. Finally, it would be a most sustainable gesture if these introductory essays contribute at least in part to making concerted debate in the area of developmental and behavioral genetics, with its predictable societal discriminatory potential, more debatable through enhanced understanding and appreciation of real issues and their real implications. Proper goals are rarely achieved without an understanding of what is involved, but misunderstanding too can be destructive of the well-being of individuals, and society's failure to deal effectively with issues that are both genetically influenced and environment sensitive too can be destructive. The issue of "genetic opportunity," its absence, and its potential politically and socially uses is as central as any theme underlying Nature Versus Nurture. This book explores the very essence of this juxtaposition. It is designed to serve as an update for practitioners; as an alternate supplement for a text that still majored in advances and methodology; as a rudimentary yet sophisticated resource for your undergraduate course in genetics.

2.1. Historical Perspectives on Nature and Nurture

Nature and nurture scores of years following the formulation of the nature vs. nurture representation in-depth results of countless studies on environmental development, the position is still not clear. Some authors argue that development is less a matter of genes than previously believed. Others argue that genetic influences and upbringing count for roughly 50-50 each. And in some quarters people express resignation that the question may never be answered with an appropriate level of detail and certainty. Publication of results demonstrating the importance and malleability of early experience and showing causality and biological potential in the genes, brains, and behaviors of typical people of different genetic backgrounds has great capacity to inform practice and policy on matters central to human welfare and social justice. Historical Perspectives on Nature and Nurture We often hear social and personality development described as interacting nature and nurture. This characterization of the field of development is far more deeply rooted than interest in molecular genetics on the part of developmental psychologists or their use of genetic methodologies. Indeed, twin research on the sources of intelligence and temperament and the potential for developmental process research to examine reciprocal and interactive effects of people and environment, unmeasured genetic and environmental influences, nonadditive as well as multiplicative and threshold utility of genetic predispositions has gone on for many decades. Early studies, including those of Leo Kanner's circle and Rustin Tizard, the point of departure for subsequent studies, Behavior of genetic and environmental influences on development in historical perspective.

2.2. Contemporary Theories in Genetics and Environmental Influences

There are a number of contemporary theories which provide an account of the dynamic interplay of genetic and environmental influences on development and its outcomes, taking into account the complex network of gene-environment correlations and interactions operating within the context of the developing individual. In brief, twin studies exploit the variety of difference between identical and non-identical pairs of twins to estimate genetic and environmental effects on individual differences. A number of reports of biometric studies provide a complete update on findings from a number of twin and other biometric studies. Socialization research focuses largely on the process of parental socialization, and the influence of genetic factors on the socialization process, and the extent to which environmental experiences and genetic factors in combination contribute to the diversity of individual development within families. Genetic dominance and the environment: additive and interactive theories focus on the nature of genetic dominance and the environment and whether or not environmental factors interact with genetic dominance to affect individual development in different ways. Development decision research investigates the interplay between development decisions and environmental constraints and the ways in which individuals invest their resources in children in various behavioral contexts. The developmental systems paradigm seeks to analyze how an array of complex gene actions and interactions, together with environmental factors, contribute to the development of diverse phenotypic outcomes.

3. Empirical Evidence

We review historical approaches to cloning and contrast the traditional heritability-nurture dichotomy with recent advances in molecular genetics. We examine new directions for the heritability issue, including gene-environment interactions and structures that go beyond simple additive and dominance genetic effects. We discuss the estimation of production functions and the determinants of knowledge pertaining to the causes of human differences. Summarization of the closest studies is presented, considering gestation and nurture in the form of parental time and goods. Our approach concentrates upon the skills embodied in living individuals. Early manifestations of skill, the environment: gestation and nurture, embodies skills versus purchased goods versus parental time, the nature of the skill production function, the evidence on nature so far, inferences from twin studies, adoption studies, reproductive technology, and cloning: historical perspectives and future prospects, and the new genetic research are presented. Additional auditory capabilities, tales of twins: anomalous results, the mechanics of estimating a genetic production function, the biometry of genetic transmission, contemporaneous family composition effects, handling the environment, matching siblings in ability, and econometric features of the estimates are discussed. In the economics of human development production function, information on pertinent aspects of gene structures is the stupendous breakthrough. Thinking in production function terms, sibling structures for identifying additive genetic production functions, and estimating an additive genetic production function are presented. At the minimum, nature is a term more inclusive than approximate genitive that is used thus far. Given the estimates of the additive genetic production function, we can analyze compensated welfare effects of potential technological changes. In the new frontier, the meager beginnings of a biotechnological policy perspective also apply our intellectual infrastructure to cloning.

3.1. Twin Studies and Adoption Research

We also develop arguments in this chapter, but the focus is empirical methodology, twin studies, and adoption comparisons. There are many points of contact between these two research strategies with respect to cause-of-phenotypic variation investigation. Both neatly extricate genetic and environmental sources. There are, however, important methodological and conceptual differences between them. These mainly concern the remarkable similarity between the pre- and post-natal environment of an adopted individual and the dissimilarity in the environment shared by the members of a twin pair. Such evidence appears to make the genetic argument much stronger than twin data alone. Therefore, EA is often called Applied Behavioral Genetics, which is really a sub-field. These concepts, valuable for distinguishing approaches based on the classification of traits and modeling considerations, do little more than label different but equivocal sex- and age-related environmental effects. It is a general malady of EA and T that design features derived from specific niche nudges are infrequently exploited by hypothesis tests versus alternative predictor variables such as parental characteristics.

3.2. Gene-Environment Interaction Studies

The nature of the interaction between genetic and environmental factors contributes to our understanding of the nature and nurture debate and informs our understanding of the underlying processes leading to development outcomes. It is widely accepted that the bevy of complex human development phenotypes, such as intelligence, mental health, and academic achievement, are the result of an adroit interplay between genetics and environmental factors. With this consumption and vote of confidence from the general public, researchers regularly set out to answer the question: How do genetics and environment interact to influence the development outcomes in which we are interested? The answer to this question usually involves the use of the rich and often complex nature-nurture data in which the researcher has the opportunity to analyze the way the relation of genetic and environmental measures is related to a specific outcome of interest. This chapter is not unlike many others in pursuing an answer to the question of how genetics and the environment interact, except that its focus is somewhat more specialized. Specifically, we are focused on farm-related variables, such as owning cows, pigs, or sheep, and hours spent with farm animals, and how those two farm-related types of environment measures might interact with genetics to influence a variety of development outcomes.

4. Critical Analysis

This collection of essays reflects how the eminent scholars writing here think about several of the most important questions in human development. Such underlying questions as whether the environment influences development and performance as much as we give it credit for, or whether the individual's genetic endowment does or does not set limits on life's possibilities, are the central concerns of each of the chapters. All of the contributors are attempting to further the field's understanding of the sources of and the alternatives within human development. The diverse but enlightened viewpoints represented in this volume reflect a state of confusion in the field, if not yet outright chaos. There is a growing perception that most of the earlier studies on nature/nurture are dismissed as a "just so" question. That is, if some hypothesis is important, it will be proven to be so through a variety of lenses. That is, much of the earlier work on whether or not children resemble their parents was so underwhelming in its results, that the whole enterprise usually gets dumped into the ash bin of intellectual history. It seems clear that this present uncertainty is not a desirable condition for the field of human genetics. Most of us have grown weary of the pendulum-like swing of the biobehavioral that ranges from extreme, completely environment-driven determinism over to complete genetic predetermination. The nature/nurture debate can be about anything (intelligence, personality, sexual preference, or handedness) and the issues are the same. Despite the popularity of nature/nurture over the years, and the notoriety of nature/nurture feel good stories where twins separated at birth and raised in separate houses by totally different families just like each other, little has been proven. This lack of rigor in much of the nature/nurture literature comes as a result of two key, identified problems. First, studies of human monozygotic and dizygotic twins leads to seriously flawed research because as Bouchard discusses, the separation experience of most monozygotic twins is directly proportional to the strength of the monozygote genetic predeterminism research strategies. That is, parents of monozygotic twins are more likely to separate them at birth, which increases concordances (almost a perfect 100%) for most behaviors. Second, most twin research and all family studies of human behavior are confounded and based on bias, which lead most studies to the incorrect conclusion that environments—and not genotypes—are overwhelmingly the sole reason for inbred average behavior ratings.

4.1. Strengths and Limitations of Genetic Research

While the genetic generalist model of human development finds support from the research, this does not mean that human development is entirely predetermined by one's genes. The complexity of genetic effects and the importance of individual environment assures that environmental factors play a role in development. In particular, trends from the studies summarized in this volume support the idea that environmental risks are ubiquitous, while some genetic factors only come into play under conditions of greater environmental adversity. Thus, not only do environmental conditions help determine which individuals are at greatest biological risk, but from some aspects of development, they appear to be the most critical consideration. Looking across the authors' essays, aside from the fascinating findings on specific areas of cognitive and non-cognitive development, the important fact is that genes and environment are both critical determinants of pediatric outcomes. From a policy perspective, this scientific progress has important implications. The nature-versus-nurture debate has a long history in science, dating back to the ancient Greeks who engaged in discussions on the topic of genes and environment. Developmental theories and research programs have been strongly influenced by the accumulated evidence, as well as by changing views on the relative importance of genes and environment in shaping human development. It certainly seems that the pendulum is swinging back towards an understanding of the interplay of genes and environment in human development.

4.2. Implications for Education and Public Policy

This paper revisits an old question with a novel approach: Given two individuals with identical natural abilities who perform equally well, how much does improving the performance of one individual increase the performance of the other? Four different settings are explored: (1) Team production that can be described by a fixed payoff or a production function with diminishing returns. Megastar production, a special case of the fixed payoff model when the best performer gets the prize. (2) Signals that are completely informative, completely uninformative, or of intermediate informativeness. In the intermediate case, the more informative signal is less noisy. 2.1. Summary of the results: Consider two individuals with identical abilities who do equally well, or equally bad: their objective performance levels are the same. We will ask whether improving the performance of one individual can increase the performance of the other when they do well. We are not willing to cause harm to one individual whose advantage comes at the cost of another. Fallibility or the healthy mind does not apply. And we will only answer the question in the affirmative. If we can be convinced of the validity of welfare judgments that give preference to better outcomes, we must be prepared for the equality constraints to be overturned.

5. Conclusion

In this essay, we have taken advantage of a vast body of research literature to examine some aspects of the nature versus nurture controversy. Heredity and environment are known to have a profound and widely divergent impact on human aptitudes and social skills. Without reviewing all of that evidence, we have provided a series of vignettes on relatively independent topics of significant interest. Some of these presentations argued for the preponderance of environmental influence, some concluded that heredity plays the more dominant role, and others concluded that each source of influence plays an essential part. Our principal substantive findings are as follows: - Environmental influences substantially impact the expression of human sexual orientation and some sexual behaviors. - Although several researchers have found substantial sex differences in cognitive abilities, these findings have been neither consistent nor conclusive. - The "Flynn-effect" provides conclusive evidence that environment and experience have a substantial impact on cognitive abilities, even late in life. - Genotype plays a significant role in influencing the course and creative accomplishments in human lives. What is less widely recognized, however, is the potential role for unique and extreme experience to interact with genotype to produce superior creative outcome. These findings might suggest that most serious human attributes have been influenced to some degree by both heredity and environment. But what is also clear from this exploration is the fact that conclusions drawn from any singular study often depend on the researcher's point of view when designing the study such that the findings are likely to reinforce that original predisposition. Yet even though such a presentation may not give us a definitive answer to any of the questions posed, papers of this sort can produce a more comprehensive answer by providing evidence from a very large set of diverse studies together in a single sitting. There is no substitute for thorough, disciplined empirical investigation to the scientific process, and thinking and learning such as this can provide a helpful guide for further exploration of the nature-nurture phenomenon.

5.1. Summary of Key Findings

Nature and nurture have always been seen as opposing determinants of human development. It is time to end this absurd dispute and accord both nature and nurture their due place in the process. Both are necessary and indispensable. There is essentially no such thing as a separate structure or function of "nature" because all structures and functions are formed in interaction with the "nurture" the system is receiving. Human development is actually the interaction of innumerable forces of nature and nurture. It is this dynamism that gives life, possibilities, and diversity of development. In the end, the very essence of being human is that it is not nature or nurture but what comes from the interplay of the two. What is fixed and final and what is malleable and changeable, the possibilities of development, and the capabilities and limitations — all arise from the dynamic interplay of nature and nurture. The ancient debate on nature versus nurture has had a limited outlook. It has generally been focused on the internal processes that go on in the creation of human beings. In the more recent past, this debate has been resolved to a great extent. There is hardly any psychologist, sociologist, or human development scholar who would argue today that human development arises solely from genetic inheritance or where the environment is perceived as merely a passive transcriber of genetic activity. Preferential attention is now being given to the processes by which changes in the environment lead to transformations in either or both the genetic heritage and behavior of human beings. Despite this awareness, the societal interest in the nature-nurture debate continues, mainly because an uninformed interpretation of either perspective can lead to potentially serious misapplications of science.

5.2. Future Directions for Research

In conclusion, this book has touched on only a few areas of human development and in only the most cursory of fashions. There are so many fascinating connections between biology and environment as they converge in development and, in my opinion, much opportunity for developing a more nuanced, biologically informed understanding of developmental processes. At present, however, we are in a stage of learning how to work together to explore the nature, nurture, and their interplay in human development and in raising thoughtful questions about why it is that nature and nurture come in the packages that they do. Precisely, how is it that environment works in tandem with genetic endowment, and why is it that genetic material is distributed among individuals in the ways that it is? It will be a long time before we truly unlock the secrets of development, but in making earnest efforts to study the intimate dance between genetic and environmental influences over time, for these are complementary processes that bring about both the diversity and the similarity of human development. In demonstrating the simultaneous roles of nature and nurture in human development. None of this means that biological notions will be unduly influential relative to substantive, normative, or other domains of intellectual argument. It is clear, however, that we will do better to understand and address the very important environments unique to people, by appreciating that these unique environments are deeply shaped by the unique individuals who create them.

Sample critical essay on nature vs. nurture.

Select network

There has long been a debate about whether nature or nurture matters more in determining the traits an individual will have. In other words, do genetics or environment play a more formative role in the development of one’s personality? Nature says that our traits are influenced by genetic inheritance and similar biological factors while nurture is meant as the influence of environmental factors after conception.

We know that physical characteristics like eye color, hair color, and height can be attributed to specific genes within our DNA. But what about emotional or behavioral traits?  This sample biological essay from the essay writing services at Ultius examines the question that while some behavioral traits can be traced to certain genes, does our environment play a role in activating those genes?

Our genetic makeup

Science tells us that certain traits are most definitely attributed to genetic causes. Our eye color, skin pigmentation, and certain diseases like Tay-Sachs or Huntingdon’s chorea are all direct results of the genes we inherit from our parents. Other traits to which we can be genetically predisposed include weight, height, life expectancy, hair loss, and vulnerability to certain illnesses (McLeod 2007). Because these characteristics can be definitively connected to our biology, many speculate on whether or not genetic factors can contribute to behavioral tendencies, mental abilities, and personality traits .

Nativists, those who believe that every characteristic we have is determined only by nature, assume that the characteristics of the human species as a whole are simply a product of evolution and that the things that make us unique are a result of our own specific genetic code. They believe that the characteristics that are not observable at birth, such as personality traits, emerge later as the product of maturation.

We each have a biological clock inside us that turns certain behaviors on and off in a way that is preprogrammed from birth. An example of this would be the way our bodies change during puberty. Nativists also believe that:

“maturation governs the emergence of attachment in infancy, language acquisition, and even cognitive development as a whole” (McLeod 2007).

Bowlby’s theory of attachment views the bond between the mother and child as being an innate process that aids in our survival as a species. Likewise, Chomsky believed that language is learned through the use of an innate language acquisition device that all humans are born with (McLeod 2007). In addition, Freud speculated that traits like aggression are engrained in our DNA. 

Fraternal twins as evidence of nature over nurture

Similarly, it is often debated whether or not criminal activity can be linked to a genetic disposition. One of the biggest pieces of supporting evidence for the nature over nurture is the fact that fraternal twins exhibit similar characteristics even when they are raised apart. Often times, these twins will share behavioral traits as if they were raised together in the same place. Mental health is undoubtedly affected by our biological dispositions.

For example, bipolar is approximately five times as likely to develop when there is a family history of the condition (“Nature vs. Nurture Debate”). There are similar statistics available for a wide number of mental health conditions . Researchers also tend to place more emphasis on nature when it comes to addiction. Alcoholism, for example, can recur in families and it has been found that certain genes may influence the development of alcoholism and the way alcohol effects the body.

Alternatively, to nativists, empiricists believe that the human mind is a blank slate at birth and any characteristics we develop are a result of our experiences and environment. With point of view speculates that psychological characteristics and our behavioral tendencies are things we learned during our development. While the concept of maturation applies to the biological development we experience, any psychological growth is a result of the way we are brought up.

Attachment of infants as evidence of nurturing

An example of this would be the way infants form attachment. The formation of attachment is a direct result of the love and attention a child receives. If they are not given love and attention, the attachment will not develop. Similarly, we learn language by mirroring the speech we hear from others.

Our cognitive development is dependent on the environment and civilization in which we are reared (“Nature vs. Nurture”). Bandura’s social learning theory states that aggression is a characteristic that we learn through observation and imitation. In addition, Skinner believed that language is something individuals learn from others via behavioral shaping techniques.

Watson's ideas on environmental learning

John Watson, one of the most well-known psychologists to propose environmental learning as the dominating factor in the nature versus nurture debate, feels that our behavioral traits are purely a result of our surroundings and experiences. He felt that he could condition a new behavior in a child or alter an already existing behavior that is considered to be unfavorable (Sincero 2016).

Watson believed that he could randomly choose any baby out of a group of twelve infants and raise the child to become any type of specialist he chose. He stated that he could train any child to be anything, regardless of the individual’s talents, potentialities, and social groups.

Benefits of nurturing on mental health

Just like nature, nurture affects our mental health, as well. While someone may have a genetic disposition for one condition or another, there still needs to be an environmental trigger for that condition to develop. If there is a genetic indication that a mental condition may develop, the individual can be ‘nurtured’ in a way that can prevent the condition from developing or lessen its severity.

A neuroscientist named James Fallon discovered that he possessed the brain of a psychopath and believed that being raised in a loving and nurturing environment helped ensure that he never fully developed enough sociopathic traits for them to affect his success (“Nature vs. Nurture Debate”).

The foundations of addiction

In a similar way, the basis for addiction is not entirely determined by genetics. Certain environmental aspects, such as the habits of our friends, partners, and parents, can contribute significantly to the development of addiction. A genetic predisposition to alcoholism becomes entirely more significant when the individual in question is frequently exposed to alcohol abuse and comes to view the harmful behavior as normal.

A study conducted at the University of Liverpool found that a family history of mental health conditions was only the second strongest indicator that a mental condition would develop (“Nature vs. Nurture Debate”). The strongest predictor was life events and experiences that contributed to the development of the mental condition, such as abuse, bullying, or childhood trauma.

Meeting in the middle

Today, most people agree that our characteristics are a result of a combination of both nature and nurture. There is enough support for both sides to completely count either side out. For example, if one twin develops schizophrenia gene , the other twin has only a fifty percent chance of also developing the same condition (“Nature vs. Nurture Debate”). Clearly, both nature and nurture can affect the development of certain disorders.

The question then shifted from ‘which one’ to ‘how much?’ We know that both play a role, but which force is more important? Francis Galton was the first to pose this question during the late nineteenth century. A relative of Charles Darwin, he felt that intellectual ability was mostly attributed to genetics and that the tendency for genius to be a familial trait was the result of natural superiority (McLeod 2007).

Arthur Jenson on intelligence testing

Many others have agreed throughout history, which has spurred an influx of intelligence testing; in particular, on separated twins and adopted children. Arthur Jenson is an American psychologist who is a modern proponent of nature over nurture. Jenson cites average IQ scores in which black Americans scored significantly lower than white participants and suggested that as much as eighty percent of intelligence is inherited (McLeod 2007).

Not surprisingly, controversy developed surrounding Jenson’s claims due to the logical weakness of his argument. It was widely agreed that his study was tainted by social and political implications that are often drawn from various studies that claim to represent natural inequalities between race and other social groups. Differences in IQ scores between various ethnic groups can be explained by biases in testing methods and social inequalities in access to resources and opportunities (McLeod 2007). Similarly, it is hotly debated whether or not alleged intelligence difference in male versus female results is a consequence of biology or culture.

The importance of both nature and nurture

Now, however, the scientific world has come to understand that trying to place a numerical value on nature and nurture to judge which is more important is not really the right approach (Davies 2001). Intelligence, for example, is a complex human characteristic that can exhibit itself in a wide variety of ways from genius to basic common sense .

By attempting to place quantitative values on the separate factors, we fail to focus on the fact that biology and environment interact in a host of important and intricate ways (Ridley 2003). Today, most people agree that neither biology nor environment act independently of one another. Both are necessary for any characteristic to manifest. Because they are dependent on each other and interact in such a complex manner, it is illogical to attempt to think of them separately. 

How nature and nurture combine in the individual

Rather than defending nativists or empiricists, most psychologists are now more interested in researching the ways in which nature and nurture interact with each other to develop characteristics and traits. In psychotherapy, this means that not only does there need to be a genetic disposition required for mental disorders to develop, but there also needs to be an environmental trigger, as well (Feller 2015).

The recognition of this important relationship is especially important given the genetic advancements made during the twenty-first century. The Human Genome Project and advent of bioengineering sparked wide interest in tracing types of behavior to particular strands of DNA found on certain chromosomes (McLeod 2007). Scientists expect to soon find specific genes that are linked to criminality, alcoholism, and other characteristics.

Conclusion 

Psychologists have been debating the influence of nature versus nurture over human characteristics for a very long time. After the scientific world came to recognize that biology and environment both play a role, the emphasis shifted to determining which was more important. Now though, as we have come to truly understand the complexity of the relationship between our genetic dispositions and environmental triggers, we no longer focus on one versus the other, but rather the way they interact with and affect each other.

While it is certainly helpful in the development of certain conditions for there to be a genetic disposition, there almost always needs to be an environmental trigger that causes the characteristic to manifest in an individual. This is only a small part of this complex discussion and an example of what you can expect when you buy a critical essay from Ultius.

Nature Vs Nurture Essay for Students and Children

500+ words essay on nature vs nurture.

The topic of nature vs nurture is always a great topic of debate among people. There are great men who did work hard to achieve great heights . But still, they are some people who didn’t work that hard yet still managed to be successful.

In other words, it is a debate between hard work and talent. In the grooming of a person, the nurturing is essential. However, still, there are some individuals who were never born in a great environment . Yet by their sense of knowledge and intellectualism created a special place in the hearts of people.

Nature has given us many things in life and one of them is talents. Either we are born as the only individual in our family or it is in our genes. Furthermore, nature plays a vital role in deciding the future of a child. Many singers in this era are born with beautiful voices. They did not need any nurturing. Their talent took them to heights they couldn’t even imagine.

For instance, some of the great legends like Lata Mangeshkar, Asha Bhosle, Kishor Kumar had soulful voices. Also, they were the ones who sang from their childhood days. They started their careers and became successful at a very early age. Moreover, they did not get much teaching but still are the legends of all time.

Apart from singing, there are other talents that nature has given us. Various scientists like Albert Einstein , Isaac Newton , Galileo Galilei, started their work in their teenage years. They had amazing intellectualism, because of which they got recognition in their entire world. Furthermore, these scientists did not get any mentoring. They did everything on their own. Because they had extraordinary intelligence and ambition in life.

On the other hand, the nurturing of a person is important. Because hard work beats talent. With proper mentoring and practice, a person can achieve success in life. If a person has an environment in which everybody is in the same profession and are successful in it.

Then there is a great chance that the person will land up in the same profession and will achieve heights. Because in that environment he will get proper nurturing.

Furthermore, he will also be able to perform better over the years. “ Hard work always pays off ”. This idiom is always true and nobody can deny that. If a person has true dedication then it can beat talent. Various singers, dancers, musicians, businessmen, entrepreneurs did work really hard for years.

And because of that, they got recognition in the entire world. In these categories, musicians are who achieved heights only with their hard work and constant practice.

It is true that there are no shortcuts to success. Various known legends like Bob Dylon. Lou Reed, Elvis Persley, Michael Jackson worked hard throughout their lives. As a result, they were some of the great personalities in the entire world.

Q1. What is the meaning of nurture?

A1. Nurture means the way a person grooms himself. This is done in order to achieve success. Nurturing is essential in a person’s life because it can be a way a person can cross the barrier and do something great. Moreover nurture also means the mentoring and care a person is getting in an environment.

Q2. What is the difference between Nature and Nurture?

A2. The main difference between nature and nurture is, nature is the talent a person inherits from his parents or is God gifted. While nurturing is hard work and mentoring of a person in a particular field. So that he may excel in that field.

Essay Sample: Nature Versus Nurture

26 March, 2020

7 minutes read

Author:  Kate Smith

This sample is a great example of the compare and contrast essay writing. It presents two points of view on what influences the development of a personality the most - genetics or environmental factors. Don't hesitate to read it to see what such a type of essay should look like when written professionally!

Nature and nurture is a hotly contested argument concerning what influences the behavior and personality attributes of individuals. Nature is entirely dependent on the genetic combination of an individual which dictates their character and appearance. On the other hand, nurture is dependent on the environmental factors that an individual gets exposed to which end up shaping his or her personality. Nature and nurture influence individuals to a certain extent because individuals get exposed to both of them in one way or the other dictating their development process.

Nature principle holds that biological characteristics of individuals get inherited from the genetic makeup in their lineage. Character traits such as height, weight, vulnerability to certain illnesses and skin complexion are inherited and determined by the genetic combination of individuals. Such biological combination is usually similar amongst individuals who are blood relatives, and for this reason, they tend to have almost a uniform genetic combination. Moreover, other behavioral, mental and personality attributes are also a reflection of our genetic makeup and usually inherited from individuals’ close blood relatives (Kong et al. 2018). Through the traits, it is easier to identify closely related individuals just by looking at their appearance and conduct.

Besides, specific characteristics do not become evident during birth, and when a person reaches a certain age, for instance, during puberty, that is when the hidden attributes begin showing up. The biological clock guides such characteristics, and when the right time comes, the physical and behavioral attributes mature and become conspicuous. Such traits get programmed in a way that for them to grow visible, they will take a certain period to develop. Moreover, they are also dependent on other biological factors within our bodies for them to manifest. However, the traits still maintain the genetic combination and the similarity of a specific lineage.

On the contrary, through nurture, an individual acquires specific attributes from the environment that surrounds them. When a child is born, for instance, its mind is black and empty. It is through its interaction with the surrounding and the people around it that will make the infant acquire some of their traits through learning, observation and aping their conducts. In other words, nurturing is dependent on the environment, experience, and learning as the individual interacts with the environment with time (Vazsonyi, Roberts, Huang & Vaughn, 2015). The way an individual was nurtured or brought up will influence their aspect of child development. Maturation will only affect biological development. The environment plays a vital role in the development process.

Similarly, the type of relationships also plays a crucial role in the nurturing, especially during child development. For instance, an infant develops an emotional attachment to its parents because of the love and affection it receives. Moreover, children who are given proper care and affection will reciprocate the same while growing up. On the contrary, infants who receive harsh treatment from their parents will develop withdrawal symptoms while growing up. Also, the infants also try and learn how and what to talk by studying the speech of those around them. The cognitive development comes from the exposer that the infant receives and conditions surrounding it.

Correspondingly, certain traits are acquired based on what an individual went through. Children who got abused or molested when growing up develop specific antisocial characteristics, for instance, being high tempered, harsh and develops particular disorders. For example, bipolar disorders manifest because an individual underwent harsh treatment which affects their psychological stability after that. Some of them become abusers and molesters in their future relationships as a way of imitating and justifying what they experienced while growing up. Imitation is a way of implementing what the individual has learned during the nurturing process by putting the lessons into practice.

Striking a Balance

However, after careful analysis, psychologists have discovered that both nature and nurture are responsible for the development of an individual. Both factors interact with each other and play a crucial role in shaping up the conduct of an individual (Lux, 2014). For example, in psychopathology, it is argued that both hereditary factors and environmental conditions contribute to the development of mental disorders in individuals. The biological combinations of people closely interact with the socio-cultural set up surrounding them. Individuals are now left to make their own choices in dictating what is suitable for them and what should be left out. Nature and nurture complement each other in shaping an individual.

Conclusively, nature and nurture are broiling discussion, and both sides have valid points to justify their stands. Nature is purely based on the fact that genetic makeup influence how an individual behaves and thinks. Similarly, the natives hold that genetic factors dictate factors such as the appearance, particular illness, and intelligence levels. On the contrary, individuals who believe in nurturing hold that environmental factors are majorly involved in the development process of individuals. Children acquire traits through learning from the people surrounding them and will try to imitate the behavior after that. However, psychologists are trying their level best to strike a balance between the two school of thoughts since both sides hold valid arguments, but both nurture and nature interact with each other during the development process. Nature and nurture cannot get treated in isolation.

Nature vs. Nurture

Reviewed by Psychology Today Staff

The expression “nature vs. nurture” describes the question of how much a person's characteristics are formed by either “nature” or “nurture.” “Nature” means innate biological factors (namely genetics ), while “nurture” can refer to upbringing or life experience more generally.

Traditionally, “nature vs. nurture” has been framed as a debate between those who argue for the dominance of one source of influence or the other, but contemporary experts acknowledge that both “nature” and “nurture” play a role in psychological development and interact in complex ways.

• The Meaning of Nature vs. Nurture
• The Nature-vs.-Nurture Debate
• Identifying Genetic and Environmental Factors

The wording of the phrase “nature vs. nurture” makes it seem as though human individuality— personality traits, intelligence , preferences, and other characteristics—must be based on either the genes people are born with or the environment in which they grew up. The reality, as scientists have shown, is more complicated, and both these and other factors can help account for the many ways in which individuals differ from each other.

The words “nature” and “nurture” themselves can be misleading. Today, “ genetics ” and “environment” are frequently used in their place—with one’s environment including a broader range of experiences than just the nurturing received from parents or caregivers. Further, nature and nurture (or genetics and environment) do not simply compete to influence a person, but often interact with each other; “nature and nurture” work together. Finally, individual differences do not entirely come down to a person’s genetic code or developmental environment—to some extent, they emerge due to messiness in the process of development as well.

A person’s biological nature can affect a person’s experience of the environment. For example, a person with a genetic disposition toward a particular trait, such as aggressiveness, may be more likely to have particular life experiences (including, perhaps, receiving negative reactions from parents or others). Or, a person who grows up with an inclination toward warmth and sociability may seek out and elicit more positive social responses from peers. These life experiences could, in turn, reinforce an individual’s initial tendencies. Nurture or life experience more generally may also modify the effects of nature—for example, by expanding or limiting the extent to which a naturally bright child receives encouragement, access to quality education , and opportunities for achievement.

Epigenetics—the science of modifications in how genes are expressed— illustrates the complex interplay between “nature” and “nurture.” An individual’s environment, including factors such as early-life adversity, may result in changes in the way that parts of a person’s genetic code are “read.” While these epigenetic changes do not override the important influence of genes in general, they do constitute additional ways in which that influence is filtered through “nurture” or the environment.

Theorists and researchers have long battled over whether individual traits and abilities are inborn or are instead forged by experiences after birth. The debate has had broad implications: The real or perceived sources of a person’s strengths and vulnerabilities matter for fields such as education, philosophy , psychiatry , and clinical psychology. Today’s consensus—that individual differences result from a combination of inherited and non-genetic factors—strikes a more nuanced middle path between nature- or nurture-focused extremes.

The debate about nature and nurture has roots that stretch back at least thousands of years, to Ancient Greek theorizing about the causes of personality. During the modern era, theories emphasizing the role of either learning and experience or biological nature have risen and fallen in prominence—with genetics gaining increasing acknowledgment as an important (though not exclusive) influence on individual differences in the later 20th century and beyond.

“Nature versus nurture” was used by English scientist Francis Galton. In 1874, he published the book English Men of Science: Their Nature and Nurture , arguing that inherited factors were responsible for intelligence and other characteristics.

Genetic determinism emphasizes the importance of an individual’s nature in development. It is the view that genetics is largely or totally responsible for an individual’s psychological characteristics and behavior. The term “biological determinism” is often used synonymously.

The blank slate (or “tabula rasa”) view of the mind emphasizes the importance of nurture and the environment. Notably described by English philosopher John Locke in the 1600s, it proposed that individuals are born with a mind like an unmarked chalkboard and that its contents are based on experience and learning. In the 20th century, major branches of psychology proposed a primary role for nurture and experience , rather than nature, in development, including Freudian psychoanalysis and behaviorism.

Modern scientific methods have allowed researchers to advance further in understanding the complex relationships between genetics, life experience, and psychological characteristics, including mental health conditions and personality traits. Overall, the findings of contemporary studies underscore that with some exceptions—such as rare diseases caused by mutations in a single gene—no one factor, genetic or environmental, solely determines how a characteristic develops.

Scientists use multiple approaches to estimate how important genetics are for any given trait, but one of the most influential is the twin study. While identical (or monozygotic) twins share the same genetic code, fraternal (or dizygotic) twins share about 50 percent of the same genes, like typical siblings. Scientists are able to estimate the degree to which the variation in a particular trait, like extraversion , is explained by genetics in part by analyzing how similar identical twins are on that trait, compared to fraternal twins. ( These studies do have limitations, and estimates based on one population may not closely reflect all other populations.) 

It’s hard to call either “nature” or “nurture,” genes or the environment, more important to human psychology. The impact of one set of factors or the other depends on the characteristic, with some being more strongly related to one’s genes —for instance, autism appears to be more heritable than depression . But in general, psychological traits are shaped by a balance of interacting genetic and non-genetic influences.

Both genes and environmental factors can contribute to a person developing mental illness. Research finds that a major part of the variation in the risk for psychiatric conditions such as autism spectrum disorder, anxiety disorders, depression, and schizophrenia can be attributed to genetic differences. But not all of that risk is genetic, and life experiences, such as early-life abuse or neglect, may also affect risk of mental illness (and some individuals, based on their genetics, are likely more susceptible to environmental effects than others).

Like other psychological characteristics, personality is partly heritable. Research suggests less than half of the difference between people on measures of personality traits can be attributed to genes (one recent overall estimate is 40 percent). Non-genetic factors appear to be responsible for an equal or greater portion of personality differences between individuals. Some theorize that the social roles people adopt and invest in as they mature are among the more important non-genetic factors in personality development.

Nature-Nurture Debate: Behavioural and Biological Approaches Essay

Biological Psychology: Nature

Behavioural psychology: nurture, new perspectives on the nature-nurture debate.

Ever since Francis Galton coined the name for the two central concepts influencing human psychology in 1874, the nature-nurture debate has infiltrated all the various schools and approaches of psychology, forcing scholars to choose the most important factor (Spahn, 2010, p. 1-2). For instance, the biological approach clearly stands on the side of nature, believing that the innate qualities developed by humans through the historical process of adaptationism and contained in humans’ genetic sequence have the most significant influence on our behaviour (Spahn, 2010, p.2). Behavioural psychology, on the other hand, stresses the importance of environment and interaction with the outside world in the formation of self, almost entirely disregarding the influence of nature, except for acknowledging the innate ability to learn: “According to this perspective, explanations of behavior rely only on observable phenomena; in the most radical version of this position, no inferences regarding internal, unobservable events are made” (Gerber & Wankoff, 2010, p. 68). In the last decade, however, many scholars have developed a rather compromising view on the discourse, accepting the importance of the influence of both factors on human psychology and behaviour (Gleitman, Gross, and Reisberg, 2011, p. 17), as well as introducing new concepts and thoughts on the subject of influence.

For most biological psychologists, there is no debate: biological approach is founded on the belief that all scenarios of human behaviour are written in our DNA: “From a biological point of view also the ‘negative’ drive of ‘destruction’ must have a positive or adaptive function for the organisms and cannot be seen as an anti-biological drive of (self-)destruction” (Spahn, 2010, p. 7). In his argument for this viewpoint, Spahn (2010) explains the biological mechanism behind aggressive behaviour: “‘aggression’ is simply a necessary feature of life, not something that is externally induced by frustration or stimuli” (p. 7).

Moreover, he states that aggression in the animal kingdom generally has an active function, as it helps to preserve certain species and eliminate weaker individuals, therefore promoting natural selection. Another example of biologically determined behaviour is altruism. Spahn (2010) uses monkeys as an example of altruistic behaviour in animals, showing how “it might be good to have courageous individuals that are willing to aggressively fight against other groups (for instance in order to defend territory and resources)” (p. 9). And, whereas such behavioural pattern creates “a conflict between activities that are good for the group and those that are beneficial for the individual” (Spahn, 2010, p.8), it is considered to be more efficient in ensuring the overall survival of the group than egoistic behaviour. Both qualities, therefore, are deemed to be innate and conforming to the principles of biological psychology.

There are, however, some significant drawbacks to the biological psychologists’ view on the influence of nature. For example, as Miller (2011) states, “violent delinquents should not be held responsible, according to nature, because they are genetically programmed to act in that manner” (p. 36). Indeed, this side of the discourse provides justification for any undesirable traits, such as violent or criminal behaviour, cheating or dishonesty, and so on. Other social issues surrounding the concept of nature include the need for proper education: “If nature was the source of one’s intelligence, for example, why waste money or other resources on teaching children who were genetically inferior and thus destined for scholastic failure and social debauchery?” (Miller, 2011, p. 35). Apparently, the use of nature as the single factor defining human behaviour and personality poses a lot of limitations, which is why behaviourist approach stands on the opposite side of this debate.

Behaviourism, on the contrary, advocates the side of nurture: the very basis of this approach is the stimuli-response model, where human behaviour is seen as a response to an external stimulus. Gerber & Wankoff (2010) use the process of speech learning in children as an example of a behaviourist development pattern: “the acquisition of speech and language relied heavily on the role of imitation as well as paired associations between unconditioned stimuli (e.g., food or a bottle) and unconditioned responses (e.g., physiological vocalisations) […] Language acquisition was viewed as the result of gradual or systematic reinforcement of desirable or target behaviors” (p.69).

In general, behavioural psychologists accept the value of nature as a factor influencing the person’s ability to learn (Spahn, 2010, p. 7). However, several scholars theorise how external factors can have an impact on the very structure of the human brain. For instance, Wang (2010) explains, “the brain has the potential to be molded by environmental factors (nurture), in either a beneficial, functionally positive direction, or in a deleterious, functionally negative direction” (p. 9). He uses Down syndrome as an example of beneficial influence of nurture, due to the apparent positive impact of the environment on the patients despite the unchanging natural conditions of the syndrome: “today, children with Down syndrome typically grow up with their own family, they receive extensive early intervention and special educational support, and their cognitive and functional capacities are far greater than they were a generation ago” (Wang, 2010, p. 7).

Despite the obvious differences in approach, limitations of the behaviourists’ stand on the nature-nurture debate are the same as in the case with biological psychology: “it remains true that ‘shifting the power away from genes’ to a somewhat more autonomous understanding of ‘cultural evolution’ is not in itself a claim for any autonomy of human behaviour” (Spahn, 2010, p. 16). In support of this claim, Miller (2011) argues that, if a serial rapist was raised in a violent and sexualized environment, from a nurturist’s point of view he is not responsible for his actions (p. 37). Instead, the blame is on his family and society, even though it is unclear as to who should bear the punishment for the crime. Both approaches, therefore, shift the responsibility for the person’s actions to external factors, and this might have significant repercussions for the society.

Recent work on the nature-nurture debate has signified a new stage of thought development on the subject: “it is further likely to assume, that ‘human nature’ has in part been shaped by ‘human culture’ and that a causal interdependence or co-evolution was in fact crucial in the evolution of mankind” (Spahn, 2010, p.15). Indeed, the merging of the two opposing opinions seems to be a prevailing tendency in modern research. Moore (2011) agrees, “genetic and non-genetic factors really do interact to produce all of our traits, whether they are biological traits like eye color and brain structure or psychological traits like schizophrenia, shyness, or alcoholism” (p. 2).

Miller (2011), however, is sceptical about the merging of the two approaches: “neither of these arguments gives an individual control over one’s course of action and behaviour” (p. 34), and offers an entirely new concept to be added to the equation: the noetic. He explains that the noetic would balance the limitations of the nature and nurture viewpoints by stressing moral responsibility of an individual over his own actions, as well as the right to choose independently of external factors: “psychologists need to recognize the possibility that the noetic perspective, or the ‘soul’, may be the factor that accounts for personal differences and discrepancies not explained by nature and nurture, such as differences in dispositions and spirituality” (Miller, 2011, p. 36). Spahn (2010) also addresses the need for “a theory that incorporates the peculiar ability of man to follow and question reasons, to live out and to distance himself from his own drives, preferences, prejudices, influences and pre-determinations” (p. 16) to provide a more in-depth evaluation of human motivations and behaviour. The noetic approach stresses the value of free will in the decisions of an individual; however, certain aspects of it still depend on the concepts of nature and nurture. For example, the goals that people set for themselves in noetic are considered to be examples of free will, but Miller (2011) acknowledges that nature and nurture may at times act as limiting factors: “goals can be influenced socially and/ or genetically, but there must remain the capacity of the individual to choose to ignore such influences if desired and choose other goals” (p. 37). Thus, it is difficult to evaluate this new approach to the nature-nurture debate until more distinctive research has been done.

Clearly, both nature and nurture have a significant influence on the person’s behaviour, and there is no definite answer to the debate. Some believe that the discourse itself is “misleading” (Gleitman et al., 2011, p. 587), whereas others, on the contrary, claim that the solution to the dispute lies in seeing both nature and nurture as influential factors (Wang, 2010, p. 5). Clearly, it would be impossible for all of the scholars to agree on a single approach; however, the stream of new thoughts in the nature-nurture debate signifies a potential to “grant greater and deeper comprehension into human nature” (Miller, 2011, p. 37) through further research and the development of psychology.
