Not sure if it should be on the list but I think that epistemic certainty should be on the list as something distinct from personal humility. You can command a room by saying something like "I'm not all that smart, smart people overcomplicate this, but this is so simple..."

I tend to be a "only true wisdom is in knowing you know nothing" sort of guy, but when I run into someone who isn't like that, who seems to have it all figured out and says it with conviction, it definitely pulls at me. It does one of these:

1. Makes me think that I've overcomplicated it

2. Makes me think I have to convince him he's wrong (which is very hard to do unless you're as laser-focused as he is and he's engaging in good faith)

3. Makes me think it's not worth the effort because of what the other two options are

If you follow 1 or 3, you're ceding the argument. 2 is hard to do well.

"This is so simple..."

Reminds me of "One weird trick." Really they're two specimens of the same phenomenon. Some people essentially spam and clickbait the world with ads for themselves.
