Also the same guy who bashes established disorders like ADHD publicly and the whole field of psychiatry(calling them engineers) saying the disorder has deep psychological roots, while himself taking anti-depressants to treat his depression isn't someone worth listening to for anything substantial. This dude thinks a disorder like ADHD is just bad conscientiousness that can be fixed by reading his 12 step book.
Perhaps for some the placebo effect is enough, and Peterson becomes their savior with devotees.
I don't know, I've listened to some of his stuff and what doesn't come across as simplistic platitudes has baked in assumptions that seem unnecessary, like defining truth to be an evolutionarily useful principle.
That he inspires people doesn't surprise me, the religion of my youth did the same and was more hokum than Peterson's mythological substrate mappings.
