The phenomenon is probably that of the syllogistic fallacy, memorably explained in the following XKCD comic:

I think the difference is that Musk thinks he knows everything due to having one field of expertise, while Trump thinks he knows everything because he surrounds himself with people who tell him he knows everything.

Halo Effect in action too.  Someone even referred to him as “my liege” like fucking Michael Scott talking to David Wallace on the phone. 

So many software engineers think like this. More than any other type of engineer.

most many engineers are like this.

It can be both, man.

I’m upper management at a company deemed essential. We manage fed/state/mun. fleets all over the country. The owner and I traditionally never get along and some would consider him a selfish dick. He’s generous in some ways but he’s hard on staff and generally cheap. He sent me home a week before all of the state…

No, classic example of Narcissistic Personality Disorder.

History will not be kind to the people in power that downplayed COVID-19. The owner of my company is doing the same thing. He has played the “we’re essential” card, keeping the office open. Everyone in the office isn’t set up to work remotely, they all have desktop computers and desk phones. There are older folks with…

Also twist:  “I’m brilliant in one field, therefore brilliant in another after a quick bit of browsing data”

David and Dan, I think it’s fair to say, didn’t really understand A Song of Ice and Fire, and they thought of it more as a collection of really amazing…

Can we please get this account banned? He’s been impersonating another commenter for months now and always has a hateful attitude. He posted this same comment multiple times under different threads.

Game of Thrones tried to play the moral ambiguity game for much of its run. The fact that it ended up being a traditional good guys versus bad guys story at the end was one of its biggest failings. Hopefully, Westworld won’t go down the same path when it gets to whatever endgame the showrunners may or may not have in…

Dude, 12 year old me would be all over this. This would be 2020's Yor, The Hunter from the Future, or maybe even Megaforce!

This movies sounds pitch blech.

Damn it Barry!
