Just noticed a slight typo, fixed now. Also, at that point, most of the tests are useless and distinguishing the differences.

It's also quite weird. To me, it's completely normal. It actually took significant mental training to match up with how others think. I knew I was quick, but not that quick.

Unfortunately, it's also a coping mechanism (adhd + autism + a few more quirks). My brain handles certain tasks abnormally. E.g. I can't read emotions intuitively. I have to brute force it with general intelligence methods. I also have memory issues, again, compensated for with brute calculations.

It's a bit like being terrified of riding vehicles. You learn to cope. You then get slightly surprised when people complain how hard marathons are. You jog the 15 miles to work and back everyday! It's not that hard. You develop the skills because you need them.

Intelligence (particularly IQ) is also only a subset of being smart. I know people far smarter than me. Their IQ might not be at the same level, but they can leverage it massively more than I can. I'm a hot rod, amazing on a 1 mile track, crap on normal roads.
