Problem is there are better ways, more specific ways.
Frankly, in my life experience people with cognitive disabilities don’t need a specific numerical grade, a broader categorization is good. So the IQ metric just doesn’t tell us enough (no indication of specifically how the impairment would be, nor indication about potential other developmental issues that may require accommodation).
The problem is with how it’s used in general, which results in ableism and bigotry.
By a few. Don’t let a few bad apples ruin the bunch.
The point of that saying is once you find bad apples it’s too late for the bunch. You have to throw them all out.

I don’t see the actual utility in IQ outside of very fringe use-cases. It’s over-utilized despite being a poor metric itself.
