This section Distinguishing INFP and INTP  is to help you verify your type if you're still unsure after doing the test and reading the type descriptions.

Although they appear alike at first sight, INFPs and INTPs are very different personalities. According to David Keirsey’s Temperament Theory, the INFP belongs to the Idealist (NFs) type personality while the INTP belongs to the Rational (NTs) type personality.

As such there are several distinguishing characteristics of both personalities that will easily help you clarify your type.

  • INFPs tend to value harmony more while INTPs enjoy debates.

    INFPs desire inner harmony: they want their outer world to reflect their deeper held inner values. Hence, they appear to be friendly, kind and harmonious. However, when their values are challenged, that’s when you see someone who is stubborn in sticking to their point of view and standing their ground.

    INTPs enjoy debate and discussion of new ideas. In a discussion where sides may have to be taken, INTPs prefer to stand on neutral ground and discuss the merits and cons of each side. In fact, they enjoy these type of discussions a lot, but sometimes they are unaware that others see it as conflict view them as trying to provoke conflict.

  • INTPs have a greater tendency for a temper problem.

    INFPs are more in control of their feelings and use it quite often in their daily lives. They express their emotions through their friendliness and openness to others, although their Introverted self means others may not notice it as much. Under stress, INFPs often go silent or just withdraw from people usually.

    INTPs do not use their emotions as much in their daily lives and hence are not as adept in managing it. Under stress or pressure, an INTP will far more likely burst out in uncontrollable anger or emotion that will surprise even their closest friends. When asked to explain themselves, INTPs will often say that they felt out of control at the moment and just need some time alone.

  • INFPs have a passionate side while most INTPs display a skeptical outlook.

    INFPs have passionate dreams and desires and will share them with the world. That passion often revolves around helping, developing and empowering people in some way or another. They are often involved in the propagation of causes and may be leading a volunteer group of some kind.

    INTPs, while they have dreams, do not display such passion. Instead, they often appear skeptical about most ideas or causes that others present to them. Instead of standing with a cause they believe in, INTPs often prefer to take a skeptical look at most of them and helpfully point out flaws in their ideologies.
