So when Reddit useru/Occyzasked: “Whats a subtle sign that someone is very intelligent?”
a lot of people had thoughts on the matter.
Here’s what they said below.

“How often they’re confident in saying ‘I don’t know.'”
“They’re very good at problem-solving.

I’m pretty good at math, but not necessarily geometry.
My mind was blown.
His ability to ‘just do it’ is dumbfounding to me.

There’s also this saying: ‘Only a fool talks in absolute.’
If you compare sentences so known unintelligent people, they lack these conditions and voices absolutes only.”
