Do You Know The Smartest Personality Types? Learn Which Types Are The Brainiest

There is always one in every group. 

The know-it-all who can answer every question at trivia night. 

But are they really that much more intelligent or study that much harder? 

Or do they have a natural-born edge?

According to the research, certain personality types have a head start on the road to the Nobel Prize or winning the lightning round of Jeopardy.

There are several theories revolving around the mutual effect of personality and intelligence. 

From Myers-Briggs’ 16 personality types to the 9 Intelligence types identified by Howard Gardner, it has become apparent that overall intelligence combines traits and experiences.

What is the most intelligent personality type, regardless of how it is measured?

MTBI stands for the Myers-Briggs Type Indicator.

Psychological scientist Isabel Briggs Myers and her mother, Katharine Briggs, developed this classification system to make the Jungian theory of Psychological types understandable and valuable to the general public. 

The Myers-Briggs Type Indicator consists of four categories and six subtypes: introverted (I) or extraverted (E), sensing (S) or intuition(N), thinking(T) or feeling(F), and judging(J) or perceiving(P). 

Each person is said to have one dominant quality supported by the remaining subordinate categories, producing 16 unique personality types that are relatively accurate in explaining a person's approach to daily activities.

The Top 8 Smartest Personality Types

The INTx types are most often listed as the smartest. These personality traits, introvert, intuitive, and thinking, tend to excel in areas that define intelligence or aspects measured by traditional IQ tests: abstract conceptual logic and problem-solving. 

But which personality type is the smartest?

It is hard to know. Intelligence, like a playground see-saw, is a balancing act. And traditional intelligence does not necessarily correlate to success or even happiness.

Are Other Personality Types Less Intelligent?

There is an ongoing emphasis placed on intelligence. Who has the highest IQ? Who is the smartest in the class? We even give awards and titles, such as Valadectorian and Suma Cum Laude

But does a high IQ equate to success and even happiness? According to the MBTI, maybe not.

Several Myers-Briggs personality types show a more social or societal focus, thus scoring lower on IQ tests and earning less income. Many include the sensing and feeling aspects of personality.

ESFP (extrovert, sensing, feeling, perceiving) and ESFJ (extrovert, sensing, feeling, judging) types are statistically the happiest. But why?

ESFPs are typically optimistic, even in challenging circumstances. Their natural positivity can significantly impact how those around them process hard times. 

People are often drawn to the ESFJ personality types because they are good at helping others feel good about themselves.

So does that mean these personalities are less intelligent? Probably not.

But it may give insight into what ESFxs find important to spend their time studying – people. In fact, humans are social creatures. And sensing and feeling play a large part in successful social interactions and positive community development. 

So, here is the big question. If extrovert-sensor types have developed a way to live in the here and now, leading to everlasting happiness or success, are they not the most intelligent types? 

It depends. And just like the nature vs. nurture debate, the argument over street smarts vs. book smarts will be ongoing.
