intelligence

Albert Einstein writing on a blackboard.

Can you quickly and easily tell how intelligent someone is? There are some obvious ways to determine if someone is highly intelligent, like when you see them work out a complex trigonometry problem on a blackboard or when they can easily explain the science behind mRNA vaccines or dark matter.

But there are also those we meet at social gatherings who immediately make us think they are very smart. Usually, it isn’t because they are making a long-winded speech about the fall of the Roman Empire or explaining quarks. We know they are intelligent because of the way they interact with people and ideas.

A Redditor named SomethingAbout2020 asked people on the AskReddit forum to share the “non-obvious signs” that people are intelligent. Many of their responses centered on highly intelligent people being open-minded, curious, and not wasting their time arguing with others.

Brilliant people are confident in what they know, consider other people’s opinions, and readily admit when they don’t know the answer.


What are 15 'non-obvious' signs that someone is really smart?

1. They know what they don't know

"They acknowledge areas where they lack knowledge."

"'Never pretend to know something when you don't' is something I always teach. It covers lying and ignorance."

2. They consider other people's ideas

"They’ll listen to the other's facts and points and take them into account when giving an objection."

"One of the best developers at my last job and manager of a project I was at is an extremely intelligent person. ... One thing I noticed is how he would take everyone's opinion into account. He would take my opinions into consideration even if I'm not a smarter person or know less about development."

3. They make you feel smart

"Talking to a dumb person will make you feel smart. Talking to a smart person will make you feel dumb. Talking to a very smart person will make you feel smart."

4. They see patterns

"Part of the reason smart people throughout history are well-known is because they discovered something new and figured out how to maximize its potential. Darwin was a guy who discovered a bunch of islands with slightly different animals. He then collected and analyzed that data to come up with the theory of evolution, which was largely correct. Einstein’s theory of relativity was based off of his observation that physics acted on everything equally. He figured out that “exceptions” were because of the way high-speed objects interact with the universe’s speed limit (the speed of light). He recognized these exceptions by gathering them and recognizing the pattern between them all, then created his theory of relativity based on that."

5. They consider multiple intelligences

"They realize not everyone is smart the same way. Your 'stupid hick neighbor' might have dropped out of school in 8th grade, but he can drive your car once and tell you exactly what's wrong, then fix it. That a**hole in school that had no empathy for anyone and showed no emotion made that sci-fi sh*t you thought would never be real. Yeah, she's dingy and her worldview is tiny, but she's the best teacher you've ever met and inspires tons of kids to go on and do great things with themselves. There's no one-size-fits-all answer here, really."

People who are super bright are probably familiar with Howard Gardner's theory of multiple intelligences. The theory suggests that people have more than just one type of just one type of intelligence, like being good at mathematics. Gardener says there are several, including musical, spatial, linguistic, interpersonal, intrapersonal, and kinesthetic intelligence. This theory allows people to appreciate different forms of intelligence that may not be of the academic variety.

6. They choose their battles

"When another person is not able to process something and, therefore, sticks with his opinion, after a few tries, the smart person just gives up. There is no use in trying to make someone understand something while they already have an uneducated opinion."



7. They speak to their audience

"They know how to explain concepts on just about any level, tailoring that level to their intended audience, and without coming across as condescending in any way."

"I heard a saying that went 'you have to be an expert to explain it simply.'"

8. They're confident in their intelligence

"Not constantly bragging about their intelligence. If they truly are smart, people can figure that out pretty quickly without them doing anything to show it."

"You generally only brag about things you're insecure about because you seek validation. If you are very comfortable with your intelligence, then you may not care if someone misinterprets you and makes you look dumb or something. You have nothing to prove. That's not just for intelligence but for anything."

9. They're funny

"I think the smart people are even more funny than stupid people because smart people understand the complexity behind humor and can make their jokes reflect that."

Scientific studies show that funny people, especially those with a dark sense of humor, are more intelligent than their not-so-funny peers. Researchers argue that it takes cognitive and emotional ability to make people laugh, and analysis shows that funny people have higher verbal and non-verbal intelligence.

10. They mind their own business

"This is a big one. They keep to themselves and deal with their own drama."

11. They aren't necessarily great students

"Believe it or not 'average' or 'above average' students are often smarter than those with straight A’s on the report cards. They do enough to pass well and get what they want but don’t let the academic system control them. Life isn’t all about booksmarts. This shows they are independent thinkers and don’t get wrapped up in designed systems. Not all, but many. Many kids who are forced to always be exceptional in school can end up the worst off and can develop deeper issues."

12. They are good listeners

"They actually listen to who they are talking to as opposed to waiting for their turn to talk."

13. Curiosity

"It really does seem to be one of the single greatest differentiators between average and smart."

A meta-analysis of over 50,000 students from around 200 separate studies found that students who are curious do better in their school work over those who are not. Why is curiosity so important when it comes to IQ? “Curiosity is basically a hunger for exploration. If you’re intellectually curious, you’ll go home, you’ll read the books," Dr Sophie von Stumm, the study’s first author, said. "If you’re perceptually curious, you might go traveling to foreign countries and try different foods.”

14. Comfortable in silence

"Being comfortable enough to allow a moment of complete silence while you think when the natural instinct of most is to immediately start replying tells me that you are, at the very least, mindful of what you want to say."

15. Unattached to their opinions

"Most of the smart people I know are not pushy with their opinions; by contrast, most of the opinionated people I know are flaming morons. I don't know if there's a correlation there, but my anecdotal experience has always been that the more eager someone is to state their opinion, the less that opinion is probably worth."

How could Mouse Heaven go so terribly wrong?

In 1968 John Calhoun, a scientist and animal behavioralist, decided to create a "utopia" for mice. It would have unlimited food and water, with beautiful nesting spaces and plenty of materials for the mice to make cozy homes with. Sweet experiment! the mice were probably thinking. Much better than the Maybelline trials we're used to.

However, there was a catch, of course. There was one thing the utopia would be lacking, and that would be physical space. As the mouse population grew, overcrowding would become an issue, and Calhoun wanted to study the problems this would potentially cause. That sound you hear is the collective sigh of the disappointed mice who were stoked about the 24/7 all-you-can-eat buffet.

The experiment, dubbed Universe 25, began when Calhoun introduced four mouse "couples" into the utopian complex. A year or so later, it was overrun and the conditions had turned hellish, even though the mice had not run out of food or water.

Initially, for just the eight original mice, the square box Calhoun built included 256 nesting boxes (or apartments) stacked on top of one another. Water bottles and food dispensers were located all along the nesting spots, and mice could travel throughout the complex at will via mesh tunnels. The starter mice were also screened for diseases and the population was obviously protected from predators. The climate was controlled and comfortable. Conditions were perfect.

The first mouse pups showed up a little over three months later, with the population of the colony doubling every 55 days. Nineteen months later, there were 2,200 mice living inside the box. With such perfect surroundings, the infant mortality rate was practically zero, leading to the rapid rise in numbers.

By month 19, this rodent utopia had become an overcrowded hellscape. Calhoun noticed three alarming trends, in particular.

In short, everything was devolving into chaos and the very society of the mice began to collapse at a rapid rate.

The "Beautiful Ones" and the "Dropouts": Mice have a complex social hierarchy ruled by dominant alpha males. Sam Kean of Science History Institute Museum & Library notes that, in the wild, non-dominant males (the ones who lose macho showdowns) can skip town and start over somewhere else. But in the close quarters of Calhoun's experiment, with nowhere to hide, they were forced to hang around and viciously battle with each other over scraps. Eventually, non-dominant male mice, which Calhoun called the "Beautiful Ones," withdrew from society completely and only ate, slept, and groomed themselves.

Though resources were unlimited, certain aggressive males hoarded them anyway: The alpha males ruled over everything in the once-utopian mouse society. They kept harems of females in the apartments to mate with and fought fiercely to defend their territory. But new waves of hungry young male mice kept coming and coming, and eventually even the most dominant alphas abandoned their posts. This led to more attacks on nursing females, which in turn led to more mothers kicking their pups out of the nest early.

Birth rate declined dramatically: With the non-dominant males giving up completely and focusing on #SelfCare, dominant males too exhausted from endless battles, and females sick and tired of it all (many became asexual hermits by the end), stopped mating and giving birth entirely. Once this happened, the society was doomed. Even with plenty of food still available, cannibalism was rampant.

Calhoun was not shy about drawing parallels between his research and humanity. "I shall largely speak of mice, but my thoughts are on man, on healing, on life and its evolution," he once wrote.

There are aspects of his wild experiment that certainly sound familiar.

We live in a world with plenty of resources for everyone, but a few select people hoard more than their fair share. When you think of the rodent "apartments," it's hard not to picture densely packed urban environments where people are stacked on top of each other at every turn. Maybe on some level some of us can relate to the “Beautiful Ones” and their urge to not participate in all the ugliness and just sequester and groom themselves. You can make an argument that when the mice stopped having to worry about food and shelter, it removed the element of challenge from their lives and left them lost. Similarly, many of us are lucky enough to not have to wonder where our next meal comes from, and maybe that has something to do with our never-ending search for meaning. Some even go so far as to link more people choosing to delay having children, or not have children at all, with the collapsing society of the mice.

But Calhoun's work has also been heavily scrutinized, with some claiming it's based on shaky science. And in the end, there’s the small matter that humans are not mice. We are infinitely more complicated, and so much better suited to adapting to our environments. Kean writes, "Ultimately Calhoun’s work functions like a Rorschach blot—people see what they want to see."

It's fascinating and thought-provoking nonetheless. Watch this breakdown of the experiment shared by the National Library of Medicine in the early 1970s.

A candidate running for office.

As the old song by The Who goes, “Meet the new boss, same as the old boss.” It’s a sentiment many of us feel every time a new mayor, governor, or president takes office, and we can’t help but feel that we deserve someone better. In a country with so many brilliant scientists, business people, educators, and public policy experts, why do the least impressive of us seem to rise to power?

Philosophy expert Julian de Medeiros, a popular TikToker and Substack blogger, recently wrestled with this question, and it must have been on a lot of people’s minds because the video received over 4.2 million views. “Why does it seem like so many people in power are so dumb? It's like, why can't we get a better class of leaders?” he asked.

@julianphilosophy

Why do stupid people have so much power? #chomsky #philosophy #psychology #power

Why is it that dumb people are always in power?

Ultimately, de Medeiros believes that power and intellect are often at odds. “I've thought about it a bit more, and I think this is my thesis: that power is inherently anti-intellectual. Because what does intellect do? Intellect questions power. It speaks truth to power. It critiques power. And power doesn't like that,” he says. “And so power has to speak to the lowest common denominator. It dumbs everything down."

"It's an anti-intellectual force. And that's why it seems like those in power are also the dumbest,” he concludes his video. The commenters further expanded on de Medeiros' thesis. “Also, intellectual people question and analyse everything. A leader needs to be invested in their opinion and abide by it,” one wrote. “Because those in power or seek power cares about the power only, so they make the decisions that keep them in power no matter what is the output,” another offered.

What is anti-intellectualism?

Another reason people who are a few fries short of a Happy Meal are often voted into office is that there is a deep vein of voters who are skeptical of intellectuals. These people tend to be populists who value “common sense” over intellectualism and may see experts or highly educated people as dangerous and out of touch with the common man. So, candidates position themselves against the “intellectuals” by either being their proud, dumb selves or by taking their IQ down a few notches while in public.

Theologian and philosopher Dietrich Bonhoeffer (1906—1945) believed that dumb people often ascend to power because evil people have difficulty getting elected. So, they champion someone who may be more charismatic or connected and ride their coattails into power.

Finally, much like de Medeiros, Bonhoeffer believes there is a big difference between intellectualism and power. Therefore, once one attains power they are highly lifely to look like a buffoon. It’s as if, “Slogans, catchwords and the like… have taken possession of him. He is under a spell, blinded, misused, and abused in his very being,” Bonhoeffer says.

It’s sad to realize that the very nature of power means that those who hold office, whether we voted for them or not, will probably disappoint us at some point. But the good news from this understanding is that we are freeing ourselves from the constant disappointment of having leaders appear rather dumb. Now, whenever we meet the new boss, we can assume he's just like the old boss and be positively delighted if they wind up slightly smarter.

Highly intelligent people come in all types. Some have no problem bragging about their smarts or accolades, while others are more humble because they don’t need to call attention to their brilliance. However, without tooting their own horn, certain hallmarks of intelligence are noticeable in how they approach people and situations. It seems that having a big brain is a hard thing to hide.

One of the undeniable characteristics of someone very intelligent is that they exhibit mental flexibility. They change their opinions when they don’t have enough information on a topic and can apply what they’ve learned from one subject to another. They also tend to have a great sense of humor, proving that their brain can easily connect different ideas.

A Redditor asked people on the ProductivityCafe subforum to share the “subtle signs that someone is intelligent.” It created great conversations about the characteristics of intelligent people and how their smarts seem to influence every part of them, from their personality to their ability to avoid unnecessary conflict.

Here are 15 subtle signs that someone is very intelligent.

1. Curious about multiple subjects

"They like to learn about any and everything."

"And remember details and concepts later. A desire to understand and curiosity about the subject at hand."

2. They change their minds

"They can change their mind when presented with new information."

"This is definitely the best / most noticeable answer. Intelligent people agnostically process new information. They don’t just “automatically” deny anything that they don’t know or is inconsistent with what they already know. Intelligent people - it’s not what they know, it’s how they interpret / process new information."

"As John Nash, the mathematician allegedly once said; when the facts change, I change my mind!"

3. They process humor quickly

"They get the joke sooner than most people. Happens once in a while in movies or group settings: one person starts to laugh way ahead of everyone else. That’s one with a super fast processing mind (I know one). It is totally unconscious, so cannot be faked."

4. They like being corrected

"When you correct them, they're actually happy about it because they get to learn something new."

"100%. This is often referred to as growth mindset."


5. Great sense of humor

"Humor is a marker for intelligence. Truly dumb people aren’t funny."

"Agreed but I would add that witty or dark humor is more intelligent than mean, cruel, gross humor. If someone’s 'wit' is just the same structure of putting other people down or being gratuitously shocking or gross, then no."

"A really good sense of humor. To be really funny, you have to be very observant and able to see things in ways that others don’t."

6. They make you feel smart

"They explain some things to you in a way that makes you feel intelligent."

"Einstein said, 'If you can't explain what you are talking about to a six-year-old, you don't fully understand it yourself.'"

7. They think before they respond

"They don't react. There is always a delay... and then, they respond."

"They observe, they pause, and then comes the long encyclopedic reply."

8. They know when to be quiet

"Yes, I have come across people with no filter, and have to argue about everything, and that can be exhausting."

"Never miss a good opportunity to shut the f**k up."

9. They're great at banter

"Yes, and quick word play/good puns."

10. They ask about your thought process

"If someone is inquisitive. They want to know how and why you think the way you do. Most people don’t do this."

11. They know what they don't know

"Even very intelligent people don't know about every topic. They understand this and don't pretend to be an expert or speak to things they don't specialize in. Or they use analogies to connect it to things they do understand.They understand that there is a lot they do not know, especially about their given specialties."

"Some people have so much ego, that they have an inability to say that they don’t know the answer to a question. They’ll either give a bullsh*t answer, or try to shrug off the patient’s concerns entirely. Nobody knows everything. If you don’t know, there’s no fault in admitting that, and then using resources to find the answer."


12. Physical intelligence is important, too

"I wish people could understand intelligence in many forms—being good with your hands is intelligence. Being able to learn elaborate choreography is intelligence. Being emotionally responsive and understanding microexpressions is intelligence. It’s not just regurgitating facts. I’m a fact regurgitator myself, but I have a lot of respect for things I can’t do."

13. They don't get into drawn-out arguments

"Not raising their voice during a disagreement. Shouting over each other is to try and win an argument with intimidation rather than logic."

"Argue with an idiot and there's two idiots."

14. They think for themselves

"They don’t have herd mentality. Specifically in politics, religion, and pseudoscience."

"I remember the first time that I understood that not picking a side was a valid option for many situations. It was like a record skip moment in my head."

15. They use a bidet

"They own a bidet and don’t use toilet paper."
