Aside from creativity (which elon also excels at) and social intelligence (which he does not - or does he) it is a good predictor of intelligence. I mean psychologist or not, you can argue it til you're blue in the face but tests measure aptitude, there's a reason the entire world uses them. Saying someone is "good at tests but not good at the thing" is just a lazy argument.
Temperature measures heat, which is one of many indicators of how it'll feel outside. IQ tests measure "reasoning/problem solving, memory, pattern recognition, and information processing speed." As a psychologist you know that already! Those are a few of the many indicators of a persons intelligence! See how that works?
Carry on!
Is it perfect? Obviously not! But to say it's inaccurate is just wrong.
It's very clear that you "attempted" to call the original commenter out for false information, just 'subtly' in case you were wrong, and got called out yourself for it.
Your defensiveness is just making it more clear. That's why you're getting down voted.
Durr heigen durr durr! See I can German too
Edit: your comment said butthole and wrekt didn't it. Don't lie I know it did.
