For example, when I first started looking into finding a more permanent SO than my SLI ex-wife, I spent some time reading accounts of which types are supposed to do best together. One MBTI site asserted that the best match for ENTJ's (LIE's) was the MBTI type ISTP (LSI). Well, I've had two long-term relationships with LSI's, and they both had exactly the same ups and downs, and they both failed for the same reasons. (Increasing laziness, inability to work together towards a business goal.)
What I imagine caused those MBTI people to advocate for LIE-LSI was that they saw only the initial stages of the relationship, where the distance is easily closed and the participants find that they are sexually compatible and just have a great time together going on vacations or simply doing nothing together.
What they didn't see is that a few months down the road, both types are getting tired of being on a permanent vacation just to get along, and they are starting to clash in the Ti/Te and Fi/Fe areas.
Socionics might not be perfect, but it has better descriptions of interpersonal relationships than any of the other systems I've seen so far. I feel that when it is applied to two healthy individuals, and account is taken of the people's enneagram types (although these tend to align well between Socionics duals) and their instinctual stacks, then you have about 85% of what is needed to predict compatibility.
The last 15% has to do with life goals coinciding, having similar backgrounds and social status, and similar intelligence and health levels. Many of these, though, can start out with great differences and if the two people start living their lives together, some of these social factors will converge.
For example, my best friend in HS was an ESI whose father owned a bank. My family had very little and I had jobs through HS to earn extra money. He was physically gangly and I played sports. This didn't affect our friendship in the slightest, though. We weren't interacting on the money plane. We were supporting each other in our long-term goals. Now, he's a long distance bike rider and I have enough money to pay my bills. So it all blends, and eventually evens out.
