This section Distinguishing INFP and ISFP  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 ISFPs are very different personalities. According to David Keirsey’s Temperament Theory, the INFP belongs to the Idealist (NFs) type personality while the ISFP belongs to the Artisan (SPs) type personality.

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

  • INFPs are much dreamier than the ISFPs who are simple and down-to-earth.

    INFPs may show this by talking candidly about their ideal careers, relationships and life with people they are close to. In this sense, INFPs are future-oriented, and they are often not too concerned about the present.

    ISFPs tend to be simpler people who live in the present. They do not dream about the future often if at all; they are primarily concerned in living in the here and now. When asked about their dreams, ISFP often will give you a blank stare; to them: the intangible is hard to conceive and dreams fall into that realm.

  • INFPs are usually engaged in the arts while ISFPs are engaged in craft-related work.

    Most INFPs are involved in arts of some kind; they may be strong in literature, writing, music, art or poetry. They enjoy the arts because it allows them the self-expression of their imagination and thinking.

    ISFPs are seldom involved in the arts, unless it involves the use of their hands. They enjoy the tangible and may be involved in craft and skill related work like cooking, carpentry, fixing and repairing, sports or the like.

  • INFPs can enjoy theory while ISFPs often dislike the classroom setting.

    INFPs are comfortable with intangible concepts and theories like Economics, Higher level Math, the Sciences that often propose theoretical models to explain the real world. They can grasp concepts quickly and see its application in the real world.

    Because the classroom, especially at higher levels, deal with concepts and theories, ISFPs often have a problem staying engaged. They very much prefer the real and tangible, and prefer learning by doing where classrooms do not offer them that luxury. Hence, they often lean toward studying in vocational institutes.
