Introversion: nature or nurture?

Introversion: nature or nurture?

A question I often get as a coach is whether introversion is innate or if it develops later in life. However, the answer to this is less clear-cut than you might expect.

Introversion and extraversion are traits that have long been the subject of research. Whether someone is born an introvert or if it develops later is a question that is not easily answered. The answer lies in a combination of your genes and the environment in which you grow up.

Research shows that introversion and extraversion are largely rooted in your genes. This means that if your parents are introverted, you are more likely to be introverted as well. So, you are not born as a blank slate but already have a certain predisposition.

Brain

There are also differences in how the brains of introverts and extraverts work. Introverts, for example, are often better at deep thinking and planning because certain parts of their brains are more active. As a result, they tend to thoroughly think through situations before taking action.

Another important difference has to do with how your brain processes external stimuli. People who are extraverted often actively seek out new experiences and social contacts because their brains find this rewarding. Introverts, on the other hand, become overstimulated more quickly by too much stimulation and feel more comfortable in quieter, less busy environments.

Environment

While you are born with a certain predisposition, your environment also plays a significant role in how introverted or extraverted you ultimately become. How you are raised, the experiences you have, and the people around you can influence your behavior in a certain direction.

For example, a child who has positive experiences in social situations may learn to display more extraverted behavior, even if they are naturally more introverted. This means that your personality is somewhat flexible and can change depending on your environment.

Balance

It's important to know that most people are not entirely introverted or extraverted. Most people are somewhere in the middle and can react differently in various situations. You often notice where your preference lies by how much energy you gain from certain activities. Behavior that doesn't come naturally to you usually takes more energy. By listening to and respecting your own needs, you can maintain better balance.
