It may seem like a meme, but Idiocracy did actually nail it. Dumb and aggressive with no attention span.

Honestly, its always been anti-intellectualism. Sure not all smart people are good people, but in general empathy is a sign of intelligence, while malice and stupidity go hand in hand.

Edit: There’s also the fact that the smart tropey villains also often happen to be wealthy, and as we all know being wealthy means someone is smart/s

If they were intelligent, we wouldn’t even figure out they’re villains

Dr Evil is pretty dumb, he only surrounded himself with intelligent people. Still not an equivalent since DT is hiring idiots.

Fun fact: DT can mean alcohol withdrawal and the symptoms resemble Trump. “Severe alcohol withdrawal symptoms such as shaking, confusion, and hallucinations.”
