There Are Four Personality Types, Scientists Find

The results from over 1.5 million people showed that many clustered around these four types.

There are four distinct personality types that many people fall into, according to research from 1.5 million people around the world.

They are the ‘average’, the ‘reserved’, the ‘role models’ and the ‘self-centred’.

While psychologists usually dislike the idea of personality ‘types’, Professor Luís Amaral, study co-author, said:

“Personality types only existed in self-help literature and did not have a place in scientific journals.

Now, we think this will change because of this study.”

1. Average

Most people are ‘average’, as you would expect: they are relatively extraverted but also a little neurotic.

They are also relatively closed to new experiences, preferring to stick to what they know and not that curious about the world.

2. Reserved

Reserved people tend to be emotionally stable but more introverted.

Set against this, they are also agreeable and conscientious.

This is the quiet, unobtrusive, willing and dependable type.

3. Role Models

Role models tend to have stable emotions and be high in openness to experience, agreeableness, conscientiousness and extraversion.

This means they are friendly, hard-working, outgoing and curious.

Others naturally looked up to them because of their positive personality traits.

Professor Amaral said:

“These are people who are dependable and open to new ideas.

These are good people to be in charge of things.

In fact, life is easier if you have more dealings with role models.”

People are more likely to fit into the role model category as they get older.

Women are also more likely to fall into this category.

4. Self-centred

Self-centred people are extraverted but low in openness, agreeableness and conscientiousness.

Teenage boys are particularly likely to be self-centred, Professor Amaral said:

“We know teen boys behave in self-centered ways.

If the data were correct and sifted for demographics, they would they turn out to be the biggest cluster of people.”

People tend to get less self-centred with age.

The results come from a survey of over 1.5 million people worldwide.

All were given standard tests of the five major factors of personality: neuroticism, agreeableness, conscientiousness, extraversion and openness to experience.

The results showed that many — although not all — people tend to cluster around these four types.

Change is also possible between the groups, Professor Amaral said:

“When we look at large groups of people, it’s clear there are trends, that some people may be changing some of these characteristics over time.

This could be a subject of future research.”

The study was published in the journal Nature Human Behaviour (Gerlach et al., 2018).
