I'd like to see some data to support their claim about Mensans, but it doesn't surprise me either. I have been invited to join in the past and I declined because when I interacted with the people involved they were dreary souls with large egos, not exactly the sort of people you want to spend considerable time with. You get much more intellectual engagement making friends through work and hobbies, many of whom maybe wouldn't qualify for Mensa, but are much better to be around and perhaps more intelligent in their own ways. I've certainly had more fun covered in grease at 2AM in a race track parking lot with a few blue collar dudes wrenching over beers than I ever had sitting around with a bunch of people who think being smart for smarts sake is the highest pursuit one can have in life. All that said, the analysis in this article seems very hand-wavey and doesn't really seem to be supported. And at least for myself, I know that many of the people I've had as coworkers over the years, including myself, who are on the higher ends of intelligence have some sort of mental health issue, many of us are also on the autism spectrum (including myself). Certainly it would make sense that if someone is a genetic outlier in one respect they would likely be a genetic outlier in other respects, and not all of them positive traits. To claim otherwise requires stronger evidence which isn't really provided to counter-act the studies that uses Mensa samples.
