Personality Types – A Deeper Knowledge

Now that we’ve a basic idea on the classification of personality types, let us take the next big step.


Personality Types

Nature loves change. It relishes variation. As we evolved there was an exponential increase in the way how our intro-species traits i.e. the variation of traits among the individuals of a species. Not only did we change physically, but also changed psychologically. An interesting thing to know is that even apes (Our ancestors – at least according to Darwin ) like chimps and gorillas, exhibited introversion/extroversion characteristics.

Personality Types

So with evolution even more complex psychological traits such as ‘intuition’, ‘Feeling’ and so on developed. And these are what led to the different personalities classified based on these traits. There are more, but these traits (Explained in the previous article as “functions”) are sufficient to classify the whole of human race into 16 personality types, the same way we classify based on races based on physical traits(like Chinese, Caucasian, Indian and so on).

And Why such an amount of diversification? Why can’t we all have a single personality and live without any kind of change of opinion or tastes? The world would be a better place, don’t you think? Actually it’s a big “NO”. Well I call this, the theory of “Apples and Oranges”. If everyone in the world loved only oranges nature’s apples get wasted. And the consumption rate of oranges would get so high, which wouldn’t support the healthy survival of any species. So I guess you would’ve caught my drift by now.


A basic mistake done among all those who take the test for the first time is that, they start judging people by their real personality by the four letter alone. If someone says he’s an ENFP, they are just taken to be extroverted people who are intuitive, decide based on feelings and are open minded. There is much more than just that. There comes the “stacking order of cognitive functions”, which do all the work of deciding on a person’s complete personality.

We discussed eight preferences in the previous article. Of those, Extroversion and introversion do not actually come under functions. It’s the way in which our energy is directed. Extroverts direct their energy outward. Their thoughts, actions seems to be focused outward. And introverts on the other hand have an inwardly direction of their actions and thoughts.

So Carl Jung(Refer previous article), classified not only the individuals as introverted and extroverted but suggested that even their functions(judging, intuition ,feeling and others) take up introverted and extroverted roles.

So the functions can now be subdivided as (Explanations later on):


  • Introverted Thinking (Ti)
  • Extroverted Thinking (Te)
  • Introverted Feeling (Fi)
  • Extroverted Feeling (Fe)


  • Introverted Sensing (Si)
  • Extroverted Sensing (Se)
  • Introverted Intuition (Ni)
  • Extroverted Intuition (Ne)


These functions are stacked for each personality type in the order of the strength of each function on defining a character. The stack order consists of:

  1. The Dominant function
  2. The Auxiliary function
  3. The Tertiary Function
  4. The Inferior Function

The Dominant function has the most influence on your personality and the inferior function has the least influence.

For an example let us consider the two personalities INFP and INFJ:

Personality Types

The stack is in the order of the biggest bubble to the smallest. The biggest bubble represents the dominant function and so on.

Here if we consider the perception function of these two types which is “Intuition” we can see that INTJs have introverted intuition (They tend to be intuitive in planning their life, deciding their needs and so on) and INTPs on the other hand extraverted intuition (Their intuition is directed outwardly. They dream and innovate on things that could change the world or society as a whole).

The same thing applies for the others too. For example introverted sensors care more about observing their inner experiences and extraverted feelers can be seen expressing their feelings candidly and publicly.

Personality Types

I would encourage anyone reading this to actually think a lot on this, rather than just limiting yourself to the facts given here.  In that way, your understanding of ‘the true you’ would be deeper and much more accurate. Happy thinking.
