IQ supposedly measures general intelligence. Assuming the g-factor exists, why are we using IQ to measure it? IQ tests get tweaked so the end result will always form a normal distribution. I checked wikipedia to figure out why, but while it said some people claim that LCT is a good reason to believe the g-factor will have a normal distribution, it didn’t seem terribly confident (and it also didn’t give a source). Even “The Bell Curve” used an intelligence test that didn’t return a bell curve at all. They said they had to turn it into a bell curve to prevent ‘skew’:
But isn’t this putting the cart before the horse? Surely it would be interesting to see what distributions we would get if we did intelligence testing without a result in mind? I get that it is really difficult to measure, but if a test consistently gave us a different distribution, we could learn valuable insights into how human minds work. So is there a reason why we aren’t testing the hypothesis that general intelligence will follow a normal distribution?
