Introvert, obviously

Most Common: 5w6, 5w4, 6w5

Less Common: 1w9, 3w4, 8w7

Type 5: The aim of this type is omniscience. A complete and total understanding of all things known, and furthermore unknown. INTJs of this type pursue knowledge with a relentlessness. They use their intuition to innovate and glean insight and their Te to operate empirically and to actualize their ideas. INTJ 5s have contributed the most to the sciences, in both the practical and awe-inspiring sense.

Skepticism runs rampant. There is a strong desire to test all things themselves, and if they cannot, they will scrutinize the experiments, yielded data, and conclusions formed by others with a rigorous intensity. At the professional level, they approach their work with the intent of disproving their fondest and most closely held theories, even moreso the theories of others, believing that only the ones left alive hold any merit.

While their Te is certainly pronounced, actively skeptical, and partial to empiricism, they are by no means lacking in imagination, and gladly invite such an activity so long as some sort of testing occurs at a later point. Their outward demeanor is actually a bit deceptive, in that they reside within an internal world that is rich in symbolism, hitting upon their profoundest insights almost through play, rather than extraneous thought. 

5w6 - The Problem Solver

(Isaac Newton - Physicist and Mathematician)

5w6 INTJs are extremely methodical and empirical, frequently checking their ideas against the tangible reality for feedback. For this reason, INTJs that score as 5w6 in the enneagram are the stereotypical scientists; they champion the scientific method and may very well be the embodiment of it.

They remain detached during work, debate, and sometimes even play, viewing things from a transcendent viewpoint that will afford them new data in the most objective sense possible. Even their lead intuitive function, that is irrational in the Jungian sense, works strongly alongside their Te to produce some sort of empirical effect.

They are typically highly competent, supremely rational, excel at problem solving, and display a knack for organization that causes a strong attraction to systems and systemic thinking. Outside of the sciences they can do well in business, especially at the higher ranks, although they typically decline positions of outright leadership. 

5w4 - The Iconoclast

(Nikola Tesla - Inventor and Engineer)

5w4 INTJs tend to lean on and emphasize their Ni more than the archetypal 5w6. There is typically a creative verve to their endeavors that borders on eccentric, and a unique style of thought that is almost purely Jungian; the thinking is almost entirely visual, and seemingly more prone to intuitive leaps and “aha!” moments. 

The 5w4 is also more characteristically concerned with aesthetics. They find beauty in mathematical formulas, feel that their work is somehow personally tied to their very beings, and experience streaks of fanaticism that can range from genius to nonsensical in nature — Nikola Tesla basically invented the 20th century but also wandered around raving about how he was building a death ray and died homeless.

They are lastly, more emotionally vulnerable than the 5w6, more prone to lows of melancholy and highs of optimism. 

Famous 5w6 INTJs: Isaac Newton, Stephen Hawking, Hannibal Barca, Karl Marx, John Maynard Keynes.

INTJ: Best: Insightful voice of reason who just KNOWS what is best for the rest of us and where we should be heading, can convince others with rational, relatable arguments.

Worst: Cult-like leader with a “You’re either with us or against us” mentality. Can be delusional and out of touch with reality and not realize how over-dramatic and theatrical they are. 

INTP: Best: Extremely wise and knowledgeable person who can come off as a borderline idiot savant knowing everything and anything. They can contradict your most cherished beliefs and turn them on on their head in a way that actually makes you think. Worst: Internet troll who probably lives in his parent’s basement attacking people behind the safety of a monitor all in the name of feeling intellectually superior because they haven’t actually accomplished worthwhile in their lives. 

ENTP: Best: That person who can literally find any solution to any of your problems, has a deep sense of community and unity. Their delivery is dry, but you’ll ultimately find it very helpful.

INFP: Best: Iconoclastic person who sees reality in a very unique and interesting perspective, super open minded and dreams of bigger and better things. Always optimistic. Weird in all the right ways. Worst: Uselessly rebellious and defiant and thinks they just know better than anyone yet have probably not accomplished anything in their lives because society just doesn’t “get” them. 

ENFP: Best: Surprisingly realistic person who just seems to have a grasp on the ins and outs of society and reality, yet pushes everyone to be themselves. Sharp, witty, can back up anything they believe in with a million arguments, leaving you with no possible loophole to burst their bubbles. Worst: SJW at it’s worst, aggressively attacking you if you don’t agree with them. ready for any argument yet will run around in circles without even realizing it. Think that spouting off ideals and arguments is just as effective if not, stronger than actually doing something about them.

Worst: Narrow-minded follower of conventions who hates anything new and progressive. Very blunt about dispelling ideals but usually with ignorant, shallow arguments to back them up.

Exceptional family figures. Worst: Goes from dictator to hot mess depending on their mood. May struggle to understand what they stand for and make up for it by attempting to be more competent than others. Can easily get caught in a mid-life crisis when they reach their 40’s all of a sudden wanting to be a 21 year old ESTP :/

ISFJ: Best: Has exceptional balance between wanting to help you but not afraid to call out your bullsh*t. Surprisingly mysterious and deep (hence why many of them are mistyped as INFx). Knows their standards, live by them, yet have this way of gently influencing others without being overbearing.

Has a fun, whimsical side to them. Can spontaneously go off projects that are both on the spur of the moment, yet carefully planned out. Worst: Acts as a social dictator, rallying others against someone they subjectively don’t like. Will absolutely make everything about them and be unable to show one ounce of independence.

Lashes out at others constantly in impatience, probably with profanities. Very low emotional intelligence and impulsive behaviors. 

ESTP: Best: Extremely fun person who constantly wants to drag you out of your comfort zone, but actually knows how to do it without you breaking out in a panic attack. Very generous, charismatic and hell bent on making you the best you can be in the real world. Worst: Essentially the used car salesman prototype who uses their charm to get what they want from others, taking what they need and never looking back with an ounce of remorse, proceeding in self-destruction. 

ISFP: Best: Very kind-hearted and loyal person who expresses their affection to others in low-key but very authentic ways. Essentially embodies the motto “Live and let live” meaning they never ever, judge you if you don’t judge them first. Can be calm, artistic and realistic all at once.

I won’t say there are no stupid questions, because there are stupid questions – however, this is not one of them. ;)

When the world says extrovert, it means: someone social and outgoing, who is always at a party or has a ton of friends. IE, Elle Woods.

When the world says introvert, it means: loner and lost in their own mind.

When MBTI says extrovert, it means: someone who is most fulfilled and stimulated when focused on the external world.

When MBTI says introvert, it means: someone who is most fulfilled and stimulated when focused on their internal world.

You can’t type people based on their behavior; you have to watch where their natural focus and energy goes, to determine introversion or extroversion. An MBTI extrovert might be quiet, shy, withdrawn, have social anxiety, etc., but if their focus is still on the outer world and they become miserable when forced into too much internal reflection, they are still a cognitive extrovert. An MBTI introvert can be charming, outgoing, social, and still prefer time to slow down and internalize their experiences before they socialize again – an introvert.
