What I find more bizarre is the other suggestion of an ideal relationship type. ESTJ. Wouldn't most INTPs be hell annoyed by the ESTJs comparitive lack of intuitive imagination, strong drive and need for organisation and strong business sense? I think an ESTJ partner would drive me crazy, and I them. It's especially funny considering the friendship section says "INTPs are likely to have friends who share their interests and pursuits. Since the INTP loves theories, ideas, and concepts, they are not likely to have much patience or understanding for people with the Sensing preference, who are not usually comfortable with abstract conceptualizing."
My main experience with an ESTJ guy occurred in an Amateur Press Association back in the 90's. He had been a founding member and acted for many years as Central Mailer (the guy who collates material and sends out issues on a scheduled basis), and he was very diligent in keeping on schedule and doing quite the professional job and was easily the most "responsible" member of the group.
However, he was also very busy and stressing because he was involved in different activities and demanded a high degree of precision/order from himself, so I took over for two years or so. Let us just say our general way of doing things was very different.
The funny thing was that we fought a lot in the early part of our relationship -- he didn't trust my competence (I was too fuzzy), and I thought he needed to get the
stick telephone pole out of his ass -- but after we got into it a few times, he became very aware that I was structured in my own way, was responsible, and was professional, and I could respect his good qualities. I also appreciated the more practical and "tangible" logic he brought to things, which helped cut through the abstract nature of my own; sometimes practical order is helpful to just make sure a job gets done and meets certain criteria consistently.
No, I don't think I could handle an actual marriage partnership with someone like that -- their need for external order would leave me feeling I was in a cage, and the lack of regard and ease for seeing and embracing intangibles on their part would leave me feeling disconnected. But as friends or coworkers, I could appreciate it.
