I watched a Jordan Peterson discussion. He used the word "proclivity" approximately 2-3 hundred times per hour.
When they call him a "dumb person's smart guy" I think it would be more accurate to say that he's "the idea of a smart person that dumb people have." kind of like how dumb people picture Mr. Monopoly (with the top hat and monocle) when they think of rich people, or Dr. Frankenstein as a scientist. Because, Jordan Peterson is more like a caricature of an intelligent person who doesn't seem particularly bright - he kept comparing everything from vaccinations to environmentalism to Nazism while slipping the word "proclivity" in there as much as he could.
I describe myself as a little dose of toxic masculinity.
