It's only human to want to know how you stack up against your peers.
That's especially true when it comes to intelligence.
Below are 13 common traits and behaviors only the smartest people display, drawn largely from a Quora thread and supported by scientific evidence. Read on and see which describe you.
The paper describes two small studies that found people with higher scores on an IQ test were slower to recognize large background movements in an image. That's likely because they focus on the most important information and filter out the rest.
The smarter you are, the more you're inclined to stay up into the wee hours of the morning, according to research.
One study, published in 2009 in the journal Personality and Individual Differences, looked at the link between childhood IQ and sleep habits among thousands of young adults. Sure enough, smarter individuals said they stayed up later and woke up later on both weekdays and weekends.
Another study, published in 1999 in the same journal, looked at about 400 US air force recruits and yielded similar findings.
Several Quora users noted that intelligent people are flexible and able to thrive in different settings. AsDonna F Hammett writes, intelligent people adapt by "showing what can be done regardless of the complications or restrictions placed upon them."
Recent psychological researchsupports this idea. Intelligence depends on being able to change your own behaviors in order to cope more effectively with your environment, or make changes to the environment you're in.
The smartest folks are able to admit when they aren't familiar with a particular concept. AsJim Winer writes, intelligent people "are not afraid to say: 'I don't know.' If they don't know it, they can learn it."
Winer's observation is backed up by aclassic studyby Justin Kruger and David Dunning, published in the Journal of Personality and Social Psychology, which found that the less intelligent you are, the more you overestimate your cognitive abilities.
In one experiment, for example, students who'd scored in the lowest quartile on a test adapted from the LSAT overestimated the number of questions they'd gotten right by nearly 50%. Meanwhile, those who'd scored in the top quartile slightly underestimated how many questions they'd gotten right.
Albert Einstein reportedly said, "I have no special talents, I am only passionately curious."
Or,as Keyzurbur Alas puts it, "intelligent people let themselves become fascinated by things others take for granted."
A study published in 2016, in the Journal of Individual Differences,suggests that there's a link between childhood intelligence and openness to experience — which encompasses intellectual curiosity — in adulthood.
Scientists followed thousands of people born in the UK for 50 years and learned that 11-year-olds who'd scored higher on an IQ test turned out to be more open to experience at 50.
Smart people don't close themselves off to new ideas or opportunities.Hammett writesthat intelligent people are "willing to accept and consider other views with value and broad-mindedness," and that they are "open to alternative solutions."
Psychologists say that open-minded people — those who seek out alternate viewpoints and weigh the evidence fairly — tend to score higher on the SAT and on intelligence tests.
At the same time, smart people are careful about which ideas and perspectives they adopt.
"An intelligent mind has a strong aversion to accepting things on face value and therefore withholds belief until presented with ample evidence,"says Alas.
Dipankar Trehan points outthat highly intelligent people tend to be "very individualistic."
Interestingly,recent research from the British Journal of Psychology suggeststhat smarter people tend to derive less satisfaction than most people do fromsocializing with friends.
Zoher Ali writes that smart people are able to overcome impulsiveness by "planning, clarifying goals, exploring alternative strategies and considering consequences before [they] begin."
Scientists have found a link between self-control and intelligence. In one2009 study, published in the journal Psychological Science, participants had to choose between two financial rewards: a smaller payout immediately or a larger payout at a later date.
Results showed that participants who chose the larger payout at a later date — i.e., those who had more self-control — generally scored higher on intelligence tests.
The researchers behind that study say that one area of the brain — the anterior prefrontal cortex — might play a role in helping people solve tough problems and demonstrate self-control while working toward goals.
Advita Bihani points outthat highly intelligent people tend to have a great sense of humor.
University of New Mexico scientists agree. One study they conducted found that people who wrote funnier cartoon captions scored higher on measures of verbal intelligence. Another study they ran found that professional comedians scored higher than average on measures of verbal intelligence.
Smart people can "almost feel what someone is thinking/feeling," says one Quora user.
Some psychologists argue that empathy, being attuned to the needs and feelings of others and acting in a way that is sensitive to those needs, is a core component ofemotional intelligence. Emotionally-intelligent individuals are typically very interested in talking to new people and learning more about them.
Mahesh Garkoti sayssmart people are likely to procrastinate on quotidian tasks, mainly because they're working on things that are more important.
That's an interesting proposition — but some scientists would say that smart people procrastinate even on work they find meaningful. Wharton psychologist Adam Grant suggests that procrastination is key to innovation, and that Steve Jobs used it strategically.
As Grant told Business Insider's Rachel Gillett, "The time Steve Jobs was putting things off and noodling on possibilities was time well spent in letting more divergent ideas come to the table, as opposed to diving right in with the most conventional, the most obvious, the most familiar."
According to Ram Kumar, intelligent individuals "wonder a lot about [the] universe and meaning of life." What's more, Kumar writes, "they always [ask] what's the point of everything?"
That existential confusion may be one reason why smart people are more likely to be anxious.As David Wilson reported in Slate, intelligent people may be better equipped to consider situations from a range of angles, meaning they're always aware of the possibility that things will go awry. Perhaps their anxiety also stems from the fact that they consider a given experience and wonder: Why bother going through it in the first place?
