Eye-Opening Facts About Every Myers-Briggs® Personality Type

For as popular as the Myers-Briggs® Type Indicator is, very few people have done the work to actually crack open the MBTI® Manual itself. If they did, they’d find themselves thoroughly immersed in facts, validity studies, reliability reports, and hundreds of pages of information about how each personality type excels differently in education, careers, marriage, and more. Let’s take a look at some of them…

Eye-Opening Facts About Every Myers-Briggs® Personality Type


According to the MBTI® Manual, of all the teachers in the world, ENFPs are the teachers least likely to see student behaviors as a serious problem. They also are the teachers who promote an internal system of belief about discipline. This means that they believe children develop from an unfolding of inner potential, as opposed to ST types who are more likely to believe that children develop as a result of external conditions or SF types who believe it’s a combination of the two. ENFPs, along with ESTJs, also have the highest coping resource scores of all the types!

In a study comparing the ranks of the 16 personality types and their aptitudes, ENTPs ranked highest in IQ among 8th graders. Male ENTPs also scored highest on two out of three measures of creativity, while females scored among three highest on one out of two measures of creativity. I guess when you think about rumored ENTPs like Leonardo da Vinci, Richard Feynman, and Steve Wozniak, this all makes sense!

According to neuroscience expert Dario Nardi, INFPs can listen in holistic ways that involve all regions of the neocortex. While other types tend to work out their responses while the other person is still speaking, INFPs wait patiently and keep listening before forming an agenda.  In fact, of all the types Nardi studied, INFPs were able to listen the longest – holding an open, receptive listening state for ten minutes or more. Nardi says that because of this “INFPs may really get to the core of a person’s psychology.”

In a psychometric assessment called SYMLOG (“System for the Multiple Level Observation of Groups”), INTPs scored highest on the value, “Tough-minded, self-oriented assertiveness” as well as “Rugged, self-oriented individualism” and “Passive rejection of popularity, going it alone”. They also scored lower than most other types on “Obedience to the chain of command, complying with authority.” This all correlates with studies in type theory showing that INTPs prefer independent thought to “group think” activities and even prefer learning alone as opposed to learning in large groups.

In a national sample, ENFJs ranked highest in “Belief in a Higher Spiritual Power”. This coincides with their over-representation in religious fields. In the religious arena, ENFJs are able to use their gift for empathy and understanding along with their inherent grasp of abstract concepts and spirituality.  Many famous ENFJs have had a strong spiritual side to them; people like Martin Luther King Jr., Johann von Goethe, Matthieu Ricard, and Maya Angelou.

When I found that I knew not only that there was God but that I was a child of God, when I understood that, when I comprehended that, more than that, when I internalized that, ingested that, I became courageous.”
– Maya Angelou

According to the MBTI® Manual, ENTJs are overrepresented among behavioral psychologists. While this may confound people who associate ENTJs with their stereotypes (“harsh, domineering types with zero empathy”), this actually makes complete sense. Behavioral psychology is concerned with discovering patterns in human behavior. Behavioral psychologists want to understand why people behave the way they do and are concerned with finding patterns in actions. They want to use this knowledge to create better habits, improve companies, and develop a better world for communities. As extraverted thinking (Te), introverted intuitive (Ni) types, behavioral psychology seems like a natural fit for ENTJs. Their thinking process wants to understand cause and effect, while their intuition wants to see patterns and predict outcomes.

According to the MBTI® Manual, INFJs ranked second lowest of all the types in “Positive affectivity”. Positive affectivity is a human characteristic that describes how much people experience positive sensations, emotions, and sentiments. High levels of this trait are marked by frequent feelings of cheerfulness, enthusiasm, and energy. There was no explanation given as to why INFJs scored so low on this trait, but perhaps science has an answer! Neuroscience expert Dario Nardi says that INFJs show higher-than-average activity in the prefrontal brain region fp2. This region admits negative input and allows us to reflect on the input at the risk of becoming sad or depressed. Nardi says “This region helps us explore and deal with information that is counter to what is typical or desirable. When we hear critics, take in violent or depressing content, or otherwise receive disruptive data, we can use this region to delve into that information, considering its meaning and how it applies to us.” Perhaps because INFJs show such strong use of this region they spend more time dwelling on the “darker” side of things (just a theory!). This would correlate with the huge numbers of INFJs who have asked me why they are interested or drawn to sad things.

In a case study, ESTPs ranked highest in “Positive affectivity” of all the 16 personality types.

They also have a penchant for playing “the good samaritan” in crisis situations.


According to the MBTI® Manual, ISFPs are overrepresented in health care and law enforcement careers. This makes sense when you study the ISFP’s cognitive functions.

These two favored functions give them a leg up in emergency fields that involve improving the quality of life for people in make-or-break situations.
