Eh its a meme at this point. Everyone knows to what you’re referring and recognises the shared experience of overconfident stupid people. Everyone educated on the topic understands that it’s a pop psychological misrepresentation of some very interesting work.

I notice it’s prevalent in populations that have had an excess of a certain type of “executive” education. Whether they are poorly educated or not… I leave to the reader.

It’s not a culture fair observation to be sure. Your Nobel prize winners I guess we’re old (hence part of a generation when smoking was more widespread). There are also countries where smoking is more or less universal.
