It's Taleb. I've got better things to do than debunk him given how he's obviously become a crank.

As for IQ in general, anyone with a bit of sense can see how obviously some people are just smarter than others, and how children tend to be similarly intelligent as their parents. Intelligence in general is _obviously_ a genetic trait: humans have it in ways animals _clearly_ do not, and different animals _clearly_ have it in different degrees.

As I said, you have to actively fool yourself to convince yourself otherwise; the burden of proof is not on my views here. The only reason there is an IQ denial movement is because IQ (especially the inherited component of it) is so utterly toxic to DEI beliefs. 

 What's DEI? 

 Diversity Equity Inclusion (pretty much on its way out) 

 that intelligence is a thing, that doesn't mean that IQ specifically as a score measures anything worthwhile, general intelligence is hard to nail down (and that it defines someones worth is a very specific view, too) 

 IQ correlates well to success in life, measured in all kinds of ways. It's not the only factor. But it is an important one.

It's just wishful thinking to believe that it doesn't. 

 i think believing that it does is the wishful thinking 🙂 in my experience, the people circlejerking over their IQ, are rarely the people that contribute a lot to anything 

 Circlejerking over IQ has little to do with having IQ. Indeed, you're assuming those people aren't lying about their IQs. 

 The harder thing to swallow is that IQ is inherited. 

 If you believe Jordan Peterson, at least in areas of his expertise, IQ is the best predictor of professional success, especially when coupled with conscientiousness (which, I think, consists of diligence plus industriousness). 

 This.
