At the core, INTJ and ENTJ are very similar and hence one type often gets confused for the other. They are both visionary doers who prioritize external measurable results. Both often are straight-shooters who dislike politics and small talks.

ENTJ’s superpowers: effectiveness and vision

The reason I put ENTJ first is because their inner workings are probably easier to imagine than that of INTJ. They are over-represented among CEOs and corporate managers, often pictured as smart, decisive and even ruthless about profit and bottom lines.

ENTJ’s superpower in leadership and strategy is derived from Extraverted Thinking (Te). Te is adept at recognizing and applying the rules of the system. It is energized by external, socially-approved rewards. Te-dominant personalities like ENTJ and ESTJ, or even INTJ and ISTJ, work really hard and are industrious. They look for measurable results and can be impatient with explanation or speculation. Their motto is “ What matters is the results, not the process”.

But what distinguishes ENTJ from ESTJ is their auxiliary function, Introverted Intuition (Ni). Ni helps ENTJ to be more imaginative and visionary. If ESTJ is more of a traditional manager, ENTJ are often innovators and change-makers who can realize and turn new technology or invention into profitable enterprises. 

Bill Gates and Napoleon Bonaparte are said to be of ENTJ types. Napoleon was well-known as an effective and ruthless conqueror, but he was also a forward-thinking law-maker who spearheaded various changes to the legal, military and political landscape of France.

The most mature ENTJs even go beyond the pull of their typical competitive and controlling Te and become magnanimous and forgiving. They are extremely protective of their team, employees, and friends. They have the vision and disciplines to push the entire company towards goals but are also flexible and open-minded enough to give individuals under them space to perform with autonomy and trust.

INTJ’s superpowers: patience, vision and integrity

INTJ’s dominant function, however, is Introverted Intuition (Ni). The chief purpose of Ni is understanding, not external achievements. It seeks clarity and truth. Especially during the younger years where Te is not yet developed, INTJs will often indulge in Ni, spending hours daydreaming and contemplating. They are voracious readers of both fiction and non-fiction and often enjoy computer games and fantasy genre when young.

As INTJ becomes more mature , their more developed Te allows them to become more engaged with the external world. They learn to channel their fountain of unique perspectives into achieving real-world objectives. If their extraverted counterparts seem like brash go-getters, INTJ’s superhuman strength lies in his extraordinary patience to plan and wait to execute with relentless precision, when all the pieces fall into the right place.

INTJ’s penchants for logic and planning often allow them to be great engineers and scientists. The more socially-inclined and ambitious type often find resounding success in the commercial world, conducting their business with cutting-edge technology and uncompromising integrity. Yes integrity is very true for INTJ who is also very much influenced by their third function, Introverted Feeling, which is the epitome of integrity and moral character.

However, logic and precision are not enough to describe INTJ’s ingenuity and potential contribution. Leading with Ni, their understanding are global and highly objective. They are forward-looking visionary leaders who can make the impossible happen for society at large. Think about Mark Zuckerberg. Though Facebook can be controversial nowadays, it is undeniable that Mark’s ambition and strategic mind have enabled an once college-campus social network to boom into a global phenomenon. 

A really good place to understand INTJ’s inner workings is the Cold-war classic Atlas Shrugged. Most of the heroes and heroines in the book are INTJ (and maybe INTP) and the author, Ayn Rand, herself is said to be an INTJ.
