If I've known them for about 6 months, and talk with them frequently enough, I can usually make a determination about their intelligence. Education and intelligence are not necessarily the same thing. I know a man who is "slow". He can barely read and write...but when it comes to fixing things, or fabricating things, he is a genius!

He/she supports Manchester United.

That depends on the definition of smart.

Usually by listening to their conversation, word usage and the like...also watch their behavior, esp. problems (or lack thereof) re: amount of discord between words and actions... and also the total effect, ie: including intentions beliefs and outlook...which has an input. Look for levels of skills.

The conventional meaning of smart is probably about overcoming another in a conflict. Smarting is the way we feel after being whipped.

Does your life run smoothly vis a vis all the manager-types in your world? When you are on the other side of the managers desk, how do you feel? You can turn that into a number too, and it should figure in, if you are very comfortable with them you might be LESS smart.

Cowtowing is not a sign of intelligence, getting abused by most managers might be the BEST sign.

In summation I would say u should draw your own conclusions. Its what u will do anyway.

Someone who doesn't follow the crowd or who thinks for themselves or the very few who have common sense 😊

By the decisions they make.
Are they forthright in their decisions, we'll thought out before acting.

Observation.

The way they speak.

How fast they respond.

How they think.

Idk.

If they can get out of tough situations.

Well I know I’m not

I don't determine people's smartness because I know it may take many different forms and that even if someone doesn't get something right away, they will eventually; it's all a matter of growth. It would be terribly unwise of me to undermine someone's capacity.

Just listen

By the decisions they make….the forethought that guides their actions….and whether they have interests in things beyond social media, the TV, and pop culture.

Someone like your self 👍

I talk with them. It's usually obvious within 3 to maybe 7 or 10 minutes.

I believe everyone is smart in something or the other.
If I can't see it immediately, I just wait for it to show up eventually.

By their degree of mental resourcefulness.... not necessarily "book smart", but those who are quick-witted and intelligent.

I have worked with some brilliant people in their scientific and engineering fields, but some of them were totally ignorant when it came to dealing with people. One Ph.D. had absolutely no sense of time, whether on a clock or calendar. The absolute smartest person was a young lady who excelled in every way. She was and is amazing!

I say people who are empathetic And compassionate towards others

Whale! (Stephen Colbert joke)

Treat people as equals , we learn from each other

Except nuclear scientists 👩‍🔬…. I don’t think us peasants are allowed to learn anything from them haha 😵

They post twice for no reason.

They can walk and chew gum at the same time.

Being smart can be over rated, it's common sense that counts.
