Suppose, hypothetically, that human brains were such that IQ was capped at 145 … it would look like the correlation between IQ and real world outcomes vanishes after 145
In your hypothetical there would be a lot of warning signs—for example all IQs above 145 would be random, that is, re-testing IQs above 145 would produce a random draw from the appropriate distribution tail.
And I suspect that it should be possible to figure out real-world distributions (the fatness of the tails, in particular), by looking at raw, non-normalized test scores.

Yes, you and I are on the same page, I was just saying that IQ shouldn’t be defined to be normally distributed.
