So what is the “best match” for an ISTP?This is tough to pinpoint but I will try to name a few types and back it up with some sound reasoning. Most personality theorists agree that when it comes to relationships, opposites don’t attract. It is our similarities that bind us together, because let’s face it, people like themselves first, and then everybody else. A little bit of difference is good, but complete opposites in MBTI usually have a hard time understanding each other. This means that ISTPs will get along well with other ISTPs and with ESTPs too (perhaps even better). Of course, that doesn’t mean you will automatically love every ISTP and ESTP you meet, but statistically you’ll “click” with these kinds of people more often than with ENFJs, for example. When we talk about similarities in MBTI, we need to focus on Jung’s judging functions behind the 4 letter MBTI type because that is the core of each person’s personality. The important functions for ISTPs are introverted thinking (Ti) and extroverted feeling (Fe). Another important similarity in relationships is the N-S dichotomy because it dictates the way we communicate. ISTPs will communicate easier with other S personalities. All this leads to the conclusion that ISTPs should get along good with ISFJs and ESFJs, because they both prioritize Fe and Ti, and are both sensing personalities, just like the ISTP. These relationships can bring that little bit of difference we mentioned earlier that can spice things up but the judging functions (Ti and Fe) are the same so there will be lots of common ground too. ISTPs also tend to like ENTJs, INTPs, ENTPs and ISTJs, but mostly in friendship, buddy or coworker relationships.
