The old trope is that there is a "fine line between genius and insanity". I was testing with above average IQ at a young age (6th grade, 11yrs old) of 160 or in that range many times since. But I have noticed that many of my family members, friends, associates and coworkers seem to look at my behavior with skew towards that bias. In my view, I think this idea that genius and insanity or abnormal behavior has been so ingrained in peoples minds that when they meet someone with elevated IQ they look for indicators to support their bias (bias confirmation). I think I am no weirder than other people, I know several people who clearly do not have elevated IQ's and they seem to "get away with" various strange behaviors but because they are "normal" it goes without notice. In my experience, once you are labeled with the big brain you come under more scrutiny than norms. Also, I don't think Mensa is a good sample, my experience is that people who seek the big brain recognition through things like Mensa may also have personality traits that trend towards those types of disorders. A true double blind study would need to be peer reviewed before I would lend any credence to this hypothesis.
