What Makes You Who You Are? The Factors That Shape Us

What makes you who you are? This is a question that has puzzled philosophers, scientists, and everyday people for centuries.

Is it your genetic makeup, your environment, your personal choices, your psychological makeup, or your physiological factors?

The answer is not straightforward, as all of these factors and more can contribute to shaping who you are as a person. Let’s explore more below.

Key Takeaways

  • Who you are is shaped by a combination of genetic factors, environmental factors, personal choices, psychological factors, and physiological factors.
  • Your genes can influence your physical characteristics, personality traits, and behaviors, but they are not the only determining factor.
  • Your environment, personal choices, psychological makeup, and physiological factors can all contribute to shaping who you are as a person.

Genetic Factors That Shape Who You Are

Genetic factors play a significant role in shaping who a person is. These factors are determined by the genes that a person inherits from their parents. While environmental factors can influence how these genes are expressed, genetic factors are largely responsible for a person’s physical and mental traits.

Inherited Traits

Inherited traits are physical or behavioral characteristics that are passed down from one generation to the next through DNA. These traits can include things like eye color, height, and hair texture. Inherited traits are determined by the combination of genes that a person inherits from their parents.

Inherited traits can also include personality traits, such as shyness or extroversion. While there is some debate over whether personality traits are completely determined by genetics or if environmental factors also play a role, research suggests that genetics do play a significant role in shaping a person’s personality.

Environmental Factors That Shape Who You Are

Environmental factors can play a significant role in shaping an individual’s personality and behavior. These factors encompass a broad range of experiences that a person encounters throughout their life.

This section will explore two sub-sections of environmental factors that can influence an individual’s development: cultural influence and social interactions.

Cultural Influence

Culture refers to the shared beliefs, values, customs, behaviors, and artifacts that a group of people use to make sense of their world and communicate with one another. Cultural influence can shape an individual’s personality and behavior in many ways.

For example, the language that a person speaks can shape the way they think and perceive the world around them. The cultural norms and expectations of a society can also shape an individual’s beliefs and values.

Furthermore, cultural influence can affect an individual’s development through the media. The media is a powerful tool that can shape a person’s perception of the world and their place in it.

For example, exposure to violent media can lead to aggressive behavior, while exposure to positive role models can lead to prosocial behavior.

Social Interactions

Social interactions refer to the relationships that an individual has with others. These relationships can include family, friends, peers, and colleagues. Social interactions can shape an individual’s personality and behavior in many ways.

For example, positive social interactions can lead to increased self-esteem and confidence, while negative social interactions can lead to anxiety and depression.

Furthermore, social interactions can affect an individual’s development through social learning. Social learning refers to the process by which individuals learn from observing others. For example, children can learn social skills and norms by observing their parents and peers.

Personal Choices That Shape Who You Are

Personal choices play a significant role in shaping who a person is. These choices can range from education to career to lifestyle.


Education is one of the most important personal choices a person can make. It not only provides knowledge and skills but also helps in developing a person’s personality. Education can be formal or informal, but both have their benefits.

Formal education provides a structured learning environment, while informal education allows for more flexibility and self-directed learning.


Career choices can greatly impact a person’s life and identity. Choosing a career that aligns with one’s interests and values can lead to job satisfaction and a sense of purpose.

On the other hand, choosing a career solely for financial gain can lead to dissatisfaction and a lack of fulfillment. It’s important to consider both personal and practical factors when making career choices.


Lifestyle choices can also shape a person’s identity. This includes everything from hobbies to daily routines to relationships.

A healthy lifestyle can lead to physical and mental well-being, while an unhealthy lifestyle can have negative effects on both. It’s important to make conscious choices about lifestyle habits and to prioritize self-care.

Psychological Factors That Shape Who You Are

There are several psychological factors that contribute to making a person who they are. These factors include personality, emotions, and beliefs.


Personality refers to the unique set of characteristics, traits, and behaviors that make up an individual. It is generally thought to be a combination of genetic and environmental factors, with some researchers suggesting that genetics may play a larger role in determining personality than previously thought.

One popular theory of personality is the “Big Five” model, which identifies five broad dimensions of personality: openness, conscientiousness, extraversion, agreeableness, and neuroticism. Each of these dimensions is thought to represent a range of traits and behaviors that are relatively stable over time.

Emotions play a significant role in shaping a person’s identity. Emotions are complex psychological experiences that involve a range of physiological, cognitive, and behavioral responses. They can be positive or negative, and can vary in intensity and duration.

Research has shown that emotions can influence a wide range of cognitive processes, including attention, memory, and decision-making.

For example, positive emotions like happiness and joy have been linked to better memory and cognitive flexibility, while negative emotions like anxiety and fear can impair these processes.


Beliefs are another important psychological factor that contribute to a person’s identity. Beliefs refer to the cognitive representations of the world that individuals use to make sense of their experiences.

They can be conscious or unconscious, and can be shaped by a variety of factors, including culture, religion, and personal experience.

Beliefs can influence a wide range of behaviors and attitudes, including political beliefs, moral values, and social norms.

For example, individuals who hold strong religious beliefs may be more likely to engage in certain behaviors or avoid others, based on their religious teachings.

Physiological Factors That Shape Who You Are

Physiological factors are those that are related to the physical body and its functions. They play a significant role in shaping an individual’s personality and behavior.

This section will discuss two sub-sections of physiological factors that contribute to making an individual who they are: Health and Physical Abilities.


Health is a crucial physiological factor that affects an individual’s personality. Good health is essential for a person to function optimally in their daily life. Poor health can lead to a lack of motivation, depression, and anxiety. It can also affect an individual’s self-esteem and confidence.

Several factors contribute to good health, including a balanced diet, regular exercise, and adequate sleep. A balanced diet provides the body with the necessary nutrients to function correctly.

Regular exercise helps to maintain a healthy weight and strengthens the body. Adequate sleep is essential for the body to rest and repair itself.

Physical Abilities

Physical abilities are another physiological factor that contributes to making an individual who they are. Physical abilities refer to an individual’s natural talents and skills.

For example, some people may have a natural talent for sports, while others may excel in music or art.

Physical abilities can also be developed over time through practice and hard work. For example, an individual may not have a natural talent for sports, but they can develop their physical abilities through regular exercise and training.

Final Note

In conclusion, understanding what makes a person who they are can be a complex and multifaceted topic. While genetics and upbringing certainly play a role, there are also many other factors that contribute to a person’s identity, including their experiences, beliefs, and values.

It is important to remember that each person is unique and that their identity is shaped by a combination of factors that are specific to them. While there may be some commonalities among people, it is ultimately up to each individual to determine who they are and what they stand for.

Overall, the journey of self-discovery is ongoing and can be a lifelong process. By exploring different aspects of themselves and reflecting on their experiences, individuals can gain a better understanding of who they are and what makes them unique. This can help them to live more fulfilling and authentic lives, and to make a positive impact on the world around them.
