"I was in a convo with a guy who has a Ph.D. in infectious diseases this summer and asking him about Covid etc. While all of us speculate and regurgitate crap we see online he was so upfront about saying “Well I haven’t seen the data on that so I can’t speak on it.” Or “That’s not my area of study, so I’m not sure.”

It was eye-opening. Out of all of my friends who could give a coherent and educated opinion about this he was the first to take himself out of the convo because he knew what he didn’t know."

"I think intelligent people are more willing to calmly debate/discuss, rather than argue. Like, you explain to them why you disagree, and they listen to you and ask further questions about your viewpoint before offering a different perspective; as opposed to an unintelligent person, who would just resort to insults when other people disagree with them."

When I had a brain tumor diagnosed last year he was the first person I reached out to.

"My paternal grandma is really intelligent, I think. She went to secretarial school in the 1950s but never really worked, so I wouldn't call her highly educated or anything. But I think she could have gone far in higher education if she'd attempted it.

I'll explain something to her, and ask her if I'm making sense. She's 90 years old - I wouldn't be at all surprised if I said something that went over her head from time to time. But she doesn't miss a step. Whenever I describe a situation or concept to her and ask her if I'm making sense, she will repeat the thing I said back to me, using different wording and her own examples to prove she absolutely understood. I don't know many other people who do that.

She also is happy to change her stance on anything when presented with new information. And a lot of times she'll bring it up again months later and thank you for showing her a new perspective. (She isn't just swayed by me because I'm her granddaughter, she's the same way with everyone else I've ever seen her interact with.)."

"They apply knowledge from one realm into a new and relevant situation.

For instance, one person described a situation (might have been on Reddit) where they were a new assistant in an academic research lab and fixed a snag that stumped all the senior researchers including the professor. The team was trying to video record their project using a strobe light and their footage wasn't working as planned.

When no one else made progress at diagnosing or solving the problem, the most junior individual spoke up and suggested that the strobe could be out of phase. They remembered that video typically records at a rate of 24 frames a minute second (thanks for the correction), and explained that along with suggesting a change to the strobe's flash rate so it would coincide with the recording.

This worked. And it really raised that individual's reputation within the group.

Inwardly they were almost embarrassed about the source of this knowledge. They had a gaming hobby back in high school, had taken some video footage of that, and discovered the standard frame rate while playing around with editing software.

But they remembered that detail years later and realized it made a difference in a completely different context.

That is intelligence."

"No joke. The smartest professor I had in engineering school was also the most humble. She was an astounding human being.

By week 2, she knew everyone's names by heart in the intro engineering course. In College. With like 180 students. Later, in upper-division classes, people would occasionally ask some really stupid questions. Like, it happens... you get so deep into some fluid mechanics derivation or something you forget something really basic. People would ask a question like this and everyone would be thinking; "Wow, how did you even make it this far?" but then... it's like she would spot the flaw in their understanding so perfectly, and then respond with such clarity and wisdom that the person asking the question would look less stupid and the whole class would be enlightened.

And here's the thing... I pride myself on being really good at that exact skill. I tutored a lot of people. I was easily one of the brightest among my peers. But that woman was on another level. It was mind-blowing. And it wasn't just her intelligence, but her organizational skills, discipline, consistency...

And yet... she was so humble. She was quiet and physically quite small. But she just exuded competence and immediately commanded every room she walked into. I've never seen anything quite like it."

The way they compose themselves, talk, write, think, explain, etc.

What I find the most interesting is that intelligent people, in my experience, are more likely to be less cold/fact-driven and more theoretical and creative. For example, if an intelligent person were to read a certain stat, fact, idea, etc, they are likely to have very interesting theoretical extrapolations.

My friend qualified for the Mensa membership, and whenever we talk, his mindset always strays towards very interesting outlooks. He has certain ideas that I would never have even thought about.
