The authenticity of Myers-Brigg’s Type Indicator

The authenticity of this amazing test:

I can bet that, the first link you get when you type “personality test”, will be that of the Myers-Brigg’s Type Indicator (MBTI) test. There are numerous personality and psychological assessment tests that are really good. But how did this particular test evolve into one of the most sought after and recommended tests of them all? That’s what this article is all about.


Why the MBTI test over the others?

The brain is the most organized part of the human system. At the same time, the most complex one too. That’s the sole reason why, even with such advancements in medical science and instrumentation, scientists are still confused and awed by its himalayan ability and functions.

But they did try their best to explore this beautiful piece of nature’s art. These days we can peek inside and observe every millisecond of our brain’s activity. You can actually watch your brain sending signals, coordinating its various modules and activating every region of it when needed. That’s where the instrument ‘EEG’ comes into play. You would’ve probably seen it in the movies where they attach these really scary circular rubber flaps all over the head and make some deduction out of it. Well that’s the instrument we were talking about. An EEG consists of electrodes attached to the scalp of one’s head. It gives a constant reading about the brain’s activity.


Spending a few hours with an EEG, produces nearly 50 million data points, which are in turn extrapolated to study the brain’s activity. The answers though they were a little messy, did not cease to amaze and inspire.

By such studies, neuroscientists were able to predict the presence of well organised modules inside this amazing piece of 1500g mass. They were able to map every module to various functions like logical reasoning, future planning and intuition. Every function was performed by an individual module, like the various types of instruments in a beautiful piece of symphony.

So every single personalities of the total 16 mbti types can be matched directly the working of the brain. Every type is like a different genre of music, just played in different styles, using different and unique instruments. While INFPs were like jazz, ENFJs were like pop.

A massive study using around 100 subjects was conducted which yielded amazing results. While INFPs had more response from the modules which favour speaking, identity, felling and imagination, INTP’s brain map showed that they favoured modules which were involved in pattern recognition, deduction and various forms of reasoning. It was found out that about 85-95% of the persons with the same personality type had similar brain maps, proving the authenticity of this type of personality classification.


Though at first this classification had its base from observed knowledge and personal myths, it has advanced so well that it is now one of the most scientifically accepted and recommended tests and classification of one’s personality.
