I've written a lot about MBTI in my PGC if anyone is curious about this. There's also this thread that includes a breakdown of personality types on 2p2 among self-reporters:

I'm still not sure how seriously I take it myself, but I have found it useful for understanding people, its whole purpose. For example, I've known three confirmed INTJs very well and each in a different phase of my life, and it makes perfect sense to me that they're all the same type and helps me understand each of them better.
Here are some takes from me re: MBTI and poker, though admittedly I haven't thought much about MBTI in awhile and my understanding atm is pretty rusty (so don't take these too seriously):
The E/I discussion above is pretty misguided. That component affects poker ability the least of any of the four. The "N" preference is almost certainly the most impactful one on poker ability, probably followed by the "T" preference. "S" types are more likely to struggle caring about theory and the long game, and "F" types are more likely to struggle with the cold logic of poker.
INTJs are the best poker players on average, almost to a certainty; the temperament suits poker perfectly. This type is the least likely to have mental game struggles and should have a solid grasp of theory. (think Cole South)
INTPS are capable of being very good but from what I've observed can struggle with some elements of poker such as getting in the heads of opponents. But they can understand some elements of poker theory extremely well. IMO this is a type that will tend to do better in online poker than live poker. (think Sklansky)
ENTPs and ENTJs are capable of being good and excelling at any aspect of the game but might struggle putting in the effort to get good and sustain a high level of play. (think Doug Polk)
INFJs (me) and INFPs are capable of being good but they need to learn how to be more objectively logical (this is probably easier for INFJs than INFPs). These types are probably the best at understanding how opponents think but they might also have the biggest mental game struggles. They're also more likely to struggle with moral issues related to winning $ off others. These types are more likely to excel at live rather than online poker and are also more likely to excel at short handed rather than full ring play. (think DGAF and Sam Abernathy)
