How Much Does IQ Matter? - Spencer Greenberg - #978

What was this study you did on intelligence? Yeah, so some people say that IQ is a pseudoscientific swindle and other people think it fully captures everything about your intelligence and says who you are as a person fundamentally. And as you probably know, there was a big replication crisis in social science where many studies failed to replicate. And so we thought, hey, we can do our part by trying to replicate a lot of claims about IQ and intelligence. So we recruited over 3,000 people.

We implemented 62 distinct intelligence tasks, which includes everything from like memorization, puzzle solving, math problems, spelling, reaction time, sort of everything you could possibly think about that you could do online automatically. And then we tested about 40 different claims that are made about intelligence and we checked if they held up. Right. Yeah, the it is intelligence is kind of like the barbell chalk and cheese. It's the uh how would you say?

It's like the cognitive Rorschach test. It's like what do you what how you see it kind of tells me probably quite a lot about your priors coming into it. You're right, it's either the fundamental underpinning that explains all of the outcomes that you're going to get in life, or it is a Nazi-ish policy that never had any basis in science and should be totally disbanded? Yeah, it's it's pretty wild.
