Some of the most retarded people alive are married people who interact with people every day.
Social interaction never helped my parents who are each significantly mentally deficient in their own ways, and in my familial circle I'm one of only two people capable of critical reason.
What social interaction actually does is improve apparent IQ because it gives you conversational practice, but apparent IQ has no bearing on actual IQ, achievement potential, or decision making wisdom.
There's a trend nowadays where people want to believe smart people are also eloquent, and they cite smart communicators like maybe Feynman, Brian Cox, Terence Tao, but in reality they're all coached to speak well and specifically about topics in their field. In real life and for regular topics they're probably average communicators at best.
Plus Musk talks every day and still talks like a sperg, even though he's undoubtedly above average in intelligence, retardedness or not aside.
