As much as it would make the world easier to understand, things like career success and advanced degrees don’t always actually mean someone is intelligent. But that doesn’t mean it’s impossible to identify someone’s mental abilities.
We’ve collected interesting and sometimes subtle examples of signs that someone is actually super smart from across the internet, from the ability to communicate with anyone to a superhuman skill at grasping new concepts. Get comfortable as you scroll through, upvote your favorites and be sure to share your own thoughts in the comments section down below.

POST Frank Ropen Frank Ropen Community Member • points posts comments upvotes FollowUnfollow 3 hours ago Nope, even intelligent people can be stubborn. Science advances often happen because better theories outlive the scientists

When they are able to explain what they want to communicate succinctly and clearly, while having an awareness of the knowledge level of the audience they are speaking to.
I've had it happen in multiple fields that I see a colleague talking to someone outside the industry using industry-specific terms and expecting people to know what the heck they're talking about. I feel that comes from a level of emotional intelligence too to consider the understanding of the listener.

Finding a connection between two VERY VERY unrelated concepts/topics. LIKE YOUR BRAIN REALLY EXPLORED THAT FAR IN A SPLIT SECOND?
i see this when they're presenting and they just make these really uncommon similes and metaphors that just make them stand out to people.
good communicators, too, oftentimes... until you let them talk about something they're really passionate about, then it's a lot of rambling and word vomit because they're too excited.

All these answers are just what an average intelligent person would do. Ask questions, don't try to sound smart etc... high intelligence is scary and unsettling when you actually witness it. It's like you realize "yea, we're definitely not created equal". The speed at which they grasp a complicated concept, put their spin on it and come up with new ideas from that concept. Their memory, processing speed and innovation just to name a few things. That usually comes with a few eccentricities though.

They inherently take into account second and third order of effects. It’s not always some genius idea but rather an idea that takes the consequences and the consequences of the consequences into account with the decisions they make.

POST Riley Quinn Riley Quinn Community Member • points posts comments upvotes FollowUnfollow 1 hour ago Good point. Many a time I've come up with an idea only to nix it after logically following through with it and realizing it either wouldn't work or would actually complicate things.

Humor. Catching a joke fast means to me they were paying attention, understand multiple angles of a subject, think very quickly, and recognize and appreciate the absurd aspect of something presented as normal.
If you tell a quick joke and a bystander laughs fast but the person you're talking to takes a while you know which one is sharper.

I think EQ is as important as IQ. Showing humility and accountability. Being self aware. Being able to admit when you got something wrong. Reflection. Understanding other people. Being in a room full of others where everyone seems fine but you can read who isn’t fine.

They’re able to understand hypotheticals and analogies. When you’re having a conversation (or debate) with someone and you make an analogy with metaphors, an intelligent person will quickly jump in and continue on the analogy. As soon as someone says ”but X is not Y” or ”but that’s not the same thing”, you know they’re not very bright.
POST Cerulean Cerulean Community Member • points posts comments upvotes FollowUnfollow 19 hours ago I agree with this only to some extent, bc analogies and metaphors can be traps. A human society is not a single human body ( needing a head etc, eg Leviathan) and your image of the human body may be wrong anyway. An atom is not a solar system at another scale. Cancer is not a human war. I love analogies, but you gotta be d**n careful to watch the built-in assumptions that slip through.

POST I am not you I am not you Community Member • points posts comments upvotes FollowUnfollow 2 hours ago My dog has eureka moments several times a week. He is doing something, and suddenly he remembers where he has hidden the bone, or other things. Then he goes and gets it, and starts looking for new places to hide them. After that he continues with what he was doing,as if nothing had happened.

If they can intuitively identify first principles. They might not even know that they’re doing it in the moment, but you can always tell from their questions. These are natural systems thinkers and potential polymaths.

When they rise above. Example they say something is this way but the “smart” person is adamant to prove them wrong. They will say “oh maybe you are right” because it shows they don’t want to argue and waste their time on a halfwit.

They see what others overlook. They possess unusually high-quality thoughts, recognize their own blind spots, and learn faster than expected. They absorb information quickly, adapt constantly, and understand situations at a deeper level.
A highly intelligent person can walk into a room, read the dynamics, identify what truly matters, and adjust their approach accordingly without needing recognition or showing everyone how much they understand.

A type of eye contact during conversation. There is a certain look in a person's eyes when they engage you in conversation that instantly reveals how intelligent they are. Hard to describe, but definitely discernable.

I’ve found a correlation with intelligence and being able to understand more accents & odd ways of explaining something. Intelligent people are also naturally more cultured.

They don't disagree with you and just nod. The only time you will hear their opinion is IF you ask them directly, and when you do, he puts in a lot of disclaimers before he states it. Normally they approach things structurally instead of normal logical progressive thought. They also often start with definitions.
tanginato , Sophia Richards Report
POST SM SM Community Member • points posts comments upvotes FollowUnfollow 3 hours ago "They don't disagree with you and just nod." This is stupid. It seems like a lot of these the people are equating "highly intelligent" with "highly sociable"; they aren't the same thing.

They try atleast to do things with good, kind and clever intent. High positive impact on structure/society/systems, atleast tries to. Often quite kind but no nonsense. Organized, understands what it is like being a beginner at something and learns how to get experience, uses past experiences to adapt in the present. Questions things.

Book smart: when they can tell you for a long time about their favorite subjects in detail
Social smart: when they tell you what they like and ask what you like?
Street smart: when they say "who asking"
Smart people also have a higher chance of becoming crazy.
pikapiki2006 , Getty Images Report
POST Kelly Scott Kelly Scott Community Member • points posts comments upvotes FollowUnfollow 2 hours ago I think I skipped all the others and went straight to crazy. The only thing I do is remember what I've read. Someone will ask me how I know a certain word and I can tell them that I read it in such-and-such a book and if I find the book, I can find the word or the phrase. Like the word "howsomever". I first read that in "The Phantom Filly" and I still get some people telling me I made that word up, even if I show them the book. But that's not being smart, it's just having a good memory.

Geobugi🇰🇷🇰🇭 Geobugi🇰🇷🇰🇭 Community Member • points posts comments upvotes FollowUnfollow 10 hours ago This is a long list of what people wish intelligent people would be. I think everybody knows somebody who is pretty clever and i bet they are different in character like everyone else. Why would they be all the same? I know one guy who is a cardiologist and he is very good in his field. It feels like there is nothing he does not know about the heart but he can never, ever admit when he is wrong. He very rarely is, that is maybe the problem, he is not used to it. Another guy who has a doctor in physics and another one in mathematics does not care a bit if somebody does not understand what he is talking about, their problem. I could go on with this list for another hour but the point is, people are all different, some are very nice and some are absolute .....holes no matter how intelligent they are. Same is true for people who are not very intelligent. Some are very sweet, some are not

Tim Douglass Tim Douglass Community Member • points posts comments upvotes FollowUnfollow 1 hour ago A great many of these are not about fundamental intelligence, but about emotional maturity and the ability to apply ones intelligence in a reasonable and rational way. This will generally only apply to intelligent people who have been well-socialized and broadly educated and have now matured, through years of experience to where they can apply their intelligence. I've worked with some very intelligent people, some who were incredibly bright in their particular area. They were mostly young and were almost universally in the difficult to horrible person category. Brilliance is very close to sociopathy in a lot of cases. Young Bill Gates was a great example. He was undeniably intelligent, but was rude, arrogant, had a superiority complex, and refused to acknowledge that there were limits to his own brilliance. It took years of life experience to overcome most of that.
