There's always someone pointing to some psychiatric study that it predicts some kind of future performance, despite the fact most of them can't be reproduced.

Out of all the subjects out there, I find psychiatric studies to be the most bullshit out of all of them. It's whatever you want it to be. I am sure if I was motivated, I would find another study that says the complete opposite.

I am a Mensan and even I find these IQ tests pointless and stupid.
