Introvert Personality: Signs, Types And Causes

Last updated on December 1st, 2023 at 08:11 am

The introvert personality is the most misunderstood group of people. Their quiet and reserved nature makes them objects of misconception and they don’t care.

Here is a video by Practical Psychology on what an introvert is:

Introverted people are seen as lacking in communication ability, being awkward in mixing with people and having poor confidence and self-esteem.

But They have something different to say about themselves as they find great joy in being who they are.

The introvert personality thrives in solitude and finds comfort in their own company or with a close-knit group, than a large one and it’s not a disorder.

An extrovert might find an introvert weird and tries to change them while the introvert might think the extrovert is an attention seeker.

Extrovert personality is more outgoing and is energized by what happens externally while being with more people.

There are many misconceptions surrounding introverted persons even though they make up about 30 to 50% of the world’s population.

Being introverted or extroverted depends on how you see, process, and digest the world around you.

These and more we are going to discuss in this article. Feel free to use the table of contents to navigate.

What is an introvert person like?

You might have heard that an extrovert is a nerd, shy, quiet, or finds it difficult to make friends or socialize.

While these attributes may be true, they are different people inside his comfort zone from what they could be outside.

They might actually be unbearable talkative when with their close-knit friends or family, the absolute opposite of what they are in public.

They focus more on what is happening in their minds and are less concerned or moved by what happens externally though they observe and keep tabs.

The Introversion personality is not impressed with large crowds or noisy environments, even if they do, they prefer to be on their own and observe rather than participate.

What are the 4 types of introverts?

Introversion personality is not a one-size-fits-all situation. It is believed that introversion is a spectrum where the sub-types have spots along the scale.

What this means is that some of them are more introverted than others. Studies indicate there are four sub-types of introversion:

  • The social introvert
  • The introspective or thinking introvert
  • The anxious introvert and
  • The inhibited introvert

The social introvert

This is the predominant sub-type personality who prefers to spend time with themselves and will strive to make sure nothing comes between them and their solitude.

If at all they have to spend time with others, it is always with very close and trusted friends or family. They enjoy their solitude and are not apologetic about it.

This behaviour is not caused by shyness or anxiety, aloofness or even indifference but by a way of life that suits them.

They set boundaries naturally by virtue of their personality and this helps filter out unwanted energies around them.

The introspective sub-type

This type almost always lives in their heads. They are intellectual and like to think and analyse every situation they come across.

Their secluded world is rich and beautiful to them and is averse to the outside world. They pretty well can judge and predict a situation by merely observing.

Their self-consciousness is high and so know how to exert themselves and avoid ugly situations long before it comes close.

Thinkers might be mistaken to be self-absorbed but truly, they think critically and always want to have a grip of all the nitty-gritty of a situation.

The anxious sub-type

This is the type that gives other introverted persons away as awkward in social situations as they struggle with interactions with others.  

They find it difficult to be active in large gatherings of people and are jittery when invited to invents because they are too anxious about crowds, people and unfamiliar spaces.

This is the type that needs to build their confidence and self-esteem. Behavioural therapy or more time in the crowd usually helps.

Restrained or inhibited sub-type

Though this type is common, you will only notice if you pay attention to them enough. They restrain themselves and study the situation taking their time before warming up to people.

This type might also appear to be afraid of socializing, but they are not. They like to meet new people but they don’t just jump in, they are selective of whom they interact or open up to.

They prefer to restrict themselves and open up to people who have earned their trust. This is why they move with a kind of mystery around them.

If you earn their trust, you earn it for a long time.

Causes of introvert personality

Introverts love solitude and find pleasure by themselves

Just like other personality types, introvert personality develops as a result of coming together of two factors – genetic and environmental or what we can also call nature and nurture.

  • The effect the environment has on our body determines our responses and this also determines if we are introverted or extroverted. The environment we grow in or how we are treated in childhood will also play a part in the type of personality we would develop.
  • Biological parents pass genes to their offspring. This means that an introverted parent can produce children with the same personality type.
  • Another determinant of introversion is the parenting style of the caregivers. A child that is restricted from socializing and making friends is likely to grow up being an introvert. On the other hand, a child who mixes up without restrictions would see socializing as a normal way of life and sees it as awkward to stay indoors.
  • Experiences with peers also have a significant effect on whether a child would be an introvert. Kids who are bullied in school would reclude and withdraw from their peers to stay safe. They find succour in their own company and grow with it.

Brain chemistry

Brain chemistry also has a role to play in determining introversion. A study conducted on dopamine system genes and behaviour in 2007 reveals that dopamine transmission plays a role in forming behaviours that have to do with impulses occasioned by stimulation.

One of the differences between introverts and extroverts is how their brains respond to dopamine, a neurotransmitter and chemical that determines pleasure and makes us have euphoria.

Extroverts are endowed with more dopamine and its receptors and so seek stimuli that release dopamine.

On the other hand, introverts have fewer dopamine receptors and are more sensitive to the low effects of exciting situations.

This is why they leave the party early to seek quiet time alone to recover from the noise and overstimulation.

Also, a different study by Fischer, R., Lee, A. & Verzijden, M.N. reveals that dopamine strongly shapes personality traits after studying 127, 685 people who participate from different parts of the world.

From the above study, researchers have a theory that the result points toward avoiding risk by the introvert.

Having a low dopamine system, introverts are inclined to avoid people and scenes to have an elevated sense of safety.

The Role of the Reticular Activating System RAS

According to Verywellmind, RAS, is a neural network in the brain that regulates arousal levels including sleeping and waking.

Psychologist Eysenck Hans of Verywellmind posits that the arousal level is a continuum.

He suggests that introvert personalities have elevated levels of arousal which explains why they seek to escape to the high stimulation that solitude gives them to reflect and digest the situation.

Myths and Misconceptions about Introverts

There are many misconceptions about the introvert personality which are a result of people grappling to understand them more.

Their rather secretive and somewhat mysterious life make people speculate and make up different thoughts about them.

Here are some of the myths about introvert personalities.

They are shy people: Introverts are not shy, they only don’t like small talking or engaging in any conversation or social situation available.

They actually engage in quality social situations that are worth their time.

Introverted personalities are not shy, they just don't like the crowd

They don’t like people: Introverts are not anti-people; they just love to be in their solitude as this is how they draw energy.

When socializing, they do so with people who understand and support their needs.

They battle with social anxiety: No! They are comfortable being who they are. It does not have anything to do with anxiety, though some introvert behaviours can be traced to that, generally, they are socially normal.

They need to change their lives and be more social: No! They prefer their lifestyle and people who understand them are not bothered.

Social situations sap their energy just as solitude saps the energy of extroverts. It gives them comfort to be so and they don’t need to change their lives to be what they don’t enjoy.

Being introverted does not stop them from being successful.
