1. ## Type compatibility (according to answers on OkCupid)

I took everyone that stated their type on OkCupid (~65,000 people, 1/3rd female) and matched them with each other (straight males with straight/bi women, bi males with bi males and straight/bi women, etc), and some numbers popped out. What do you think?

Male 1 (INTP) was matched with female 1 (INFJ), for example, then the resulting match percentage (how much of what the INTP male wants is given by the INFJ female) was stored in the ("m:intp", "f:infj") bucket. Then the reverse happened, and it was stored in the ("f:infj", "m:intp") bucket. Once everyone was matched with everyone else, the values in each bucket were averaged together. Once averaged, the average and standard deviation for the ("m:intp", ...) results were calculated, for example, then used to normalize those results. Once normalized, the lower of ("m:intp", "f:infj") and ("f:infj, "m:intp") was stored as the match percentage for that type and gender.

>= -0.4615: above average
>= 0.4470: great
>= 1.3555: exceptional

2. I'm an INTP male and the best match seems to be an INTP Female (1.3350). I'm not sure who to choose out of @Madrigal, @Lurker, @Sloth or @gator. Maybe Sloth. I think my wife is ENFP which is a score of 0.5428.

4. So based on self-reporting, people generally want someone just like themselves - surprise! I have no doubt this works for compatibility, but less so for attraction. Generally speaking, attraction is about differences, and that can be hard to predict because people often don't expect to like something very different from themselves. I am not surprised that when it comes to actual couples, a 2 letter dichotomy match is the most frequent pairing. There are a lot of reasons that could be, but I suspect it's the sweet spot for having enough differences to cause attraction, but enough similarities to be adequately compatible.

This is why OKCupid's matching system didn't work too well for me, especially when I answered MANY questions. I found that answering no more than 300 or so questions and focusing on 70-80% matches produced more attractive options than high matches after answering 1000 questions.
Either way, OKC also seemed to dredge up all the single INFJ males within a 100 mile radius and direct them to my inbox. Want to meet the fabled INFJ male? Hang around an INTP woman; we're catnip for those dudes.

When matches are similar, gaps in abilities/preferences may remain unfilled. That is, the relationship may work well, but they may not be as able to deal with problems or cover each other's weaknesses. On the other hand, it doesn't matter how well two types complement each other if they aren't happy together. It makes sense that similar types would be most compatible (in the above result), as most are likely to accept the answer they chose.

6. I think it is inaccurate and dehumanizing. You can get along with almost anyone if you really want to as long as you are not an arrogant self absorbed fool. Then you can only get along with yourself thinking you are developing relationship skills. Ha how silly. People are far too complicated and far too intricate to be reduced to 4 letters. Only a person that values and respects individuals that are less or more and different than they are can achieve the skill of relating and connecting to others.

7. I am an XNTP but generally sway more ENTP as a whole. My wife is ISXJ, which doesn't seem like it would be a good match at all on this list.

That being said I love my wife to death. She really does complement me any and every way.
