INFP and ISTJ: Compatibility, Love, Marriage, and Romance

INFP and ISTJ are nearly opposites. The rigid and authoritative ISTJ might chafe with the creative and flexible INFP, and their shared introversion can serve only to worsen the problem.

These two types tend to enjoy working alone or in smaller groups in general. This can make conversation between these two parties a bit challenging unless they are talking about a shared interest.
