Anecdote: My Dad was a MENSA member for a couple of years, but he was mostly taking the piss - he put down his "special interest" as "carved Dravidian lapis lazuli", which is not as far as I know a thing. He was an RAF V-bomber captain and never as far as I could see suffered from depression or other mental health issues (which would have affected his security clearance) - much the reverse. Edit: The lapis lazuli thing is (per Google) actually a thing, but in the early 1960s I don't see how my Dad could have come across it, but obviously he did. I could have joined MENSA (had the IQ) but thought it was all too silly and didn't. I've suffered a lot from depression. Go figure.
