The dirty truth is that once IQ gets above 140 (genius level) and certainly 145, people seem to get progressively weirder with each point climb on the brain scale.
A recent study focused on so called very high IQ people. The cutoff was 160, so they were looking at people with IQ’s of 160 and above. As you would expect, most of these 160+ IQ types were men.
Many of these men were nearly dysfunctional, living alone, never dating or marrying and rarely if ever having sex, painfully introverted to the point of crippling social phobia and just generally seem pathologically quiet and rather weird. Many of them were working at low paying jobs and living at low incomes or even living in poverty. You can have too much of anything believe it or not, and I would imagine that at levels like that, you are just too damn smart for your own good.
Sadly, many pf these men had become misanthropes. It almost seemed to go with the territory. A feeling that they were surrounded by retards or borderline retards was very common, and it was not a pleasant feeling. Most disliked their condition and said they wished they were much less intelligent than they were so they could function and be at home with ordinary people. There’s nothing fun about feeling like a freak, even if the thing you are an outlier in is a talent rather than a handicap.
Once IQ goes over 160, many people simply have got too much brains, too many cells, way too many connections. They are actually too smart. They’re going 120 while everyone else is going 35. You do that enough and of course you crash. These people are so gifted that you’re not even adaptive anymore. Their record-breaking IQ is crippling them instead of helping them. It’s a rather sad picture.
In the last century, a number of very high IQ men were found in Europe working at very menial jobs into late age. They were garbagemen, janitors, factory workers, security guards, lumberjacks, postal workers, low level clerks, truck drivers, or bar bouncers. Many had extremely boring jobs that would drive anyone else mad from the inactivity. Commonly they said that they liked the menial jobs because it gave them time to think. They wanted to run Olympic marathons in their heads all day long, and the best way to do that was to get a very menial job.
These are people to whom thinking and intellectual exercise is nearly a sensual activity (something you experience with and feel in your body) like sex, parties, dinner parties, sports, scuba diving, hiking, bike riding, skiing, hobbies, etc. Dumping trash and running around in their heads all day is the equivalent of a Caribbean cruise for regular people. They can go anywhere they want in the whole world, and they never have to leave their own heads. Not to mention the airfare savings.
