I don’t think the curve actualy looks like that. There’s a shit ton of stupid people. I think it’s more like a line starting high on the left with low IQ and trending downward to the right and higher IQ.
the curve is ordinal, meaning that most people (68% of people) will score 85-115, give or take 15 - meaning if you take the test 3 times and get 100, 93.and 107… you can consider them all roughly the same score.
That’s because most people wouldn’t struggle with:

It seems that IQ tests are always used with a normal distribution.
I don’t know whether IQ/intelligence is actually normally distributed, but it seems that IQ test results are.
