17 Signs You’re Intelligent Even If It Doesn’t Feel Like It

Stupid people tend to overestimate their competence, while smart people tend to sell themselves short. As Shakespeare set it in “As You Like It“: “The fool doth think he is wise, but the wise man knows himself to be a fool.”

That conventional wisdom is backed up by a Cornell University study conducted by David Dunning and Justin Kruger. The phenomenon is now known as the Dunning-Kruger effect.

So, if you’re not too sure about your own intellect, it actually might be a indication that you’re pretty intelligent thoughtful enough to realize your limitations, at least.

Here are some subtle signs that you are considerably smarter than you think.

You Took Music Lessons

Research suggests that music helps kids’ intellects develop in a few styles 😛 TAGEND

A 2011 analyse found that scores on a test of verbal intelligence among 4- to 6-year-olds rose after merely a month of music lessons.

A 2004 analyse led by Glenn Schellenberg found that 6-year-olds who took nine months of keyboard or voice lessons had an IQ boost compared with kids who took drama lessons or no class at all.

Meanwhile, a 2013 analyze, also led by Schellenberg, suggested that high-achieving kids were the ones most likely to take music lessons. In other words, in the real world, musical educate may only improve cognitive changes that already exist.

You’re The Oldest

Oldest siblings are usually smarter, but it’s not because of genetics, one study discovered.

Norwegian epidemiologists employed military records to examine the birth order, health status, and IQ ratings of nearly 250,000 18 – and 19 -year-old men born between 1967 and 1976. Outcomes showed that the average firstborn had an IQ of 103, compared to 100 for second children and 99 for third children.

The New York Times reports: “The new findings, from a landmark analyse published[ in June 2007 ], goes to show that eldest children had a slight but important edge up IQ an average of three points over the closest sibling. And it found that the difference was not because of biological factors but the psychological interplay of parents and children.”

For this and other reasons, firstborns tend to be more successful( but not that much more successful )~ ATAGEND than their siblings.

You’re Thin

For a 2006 analyze, scientists gave roughly 2,200 adults intelligence test over a five-year period and results suggested that the bigger the waistline, the lower the cognitive ability.

Another analyze published that same year found that 11 -year-olds who scored lower on verbal and nonverbal tests were more likely to be obese in their 40 s. The survey authors say that smarter kids might have sought better educational opportunities, landed higher-status and higher-paying tasks, and therefore ended up in a better position to take care of their own health than their less intelligent peers.

Meanwhile, a more recent analyze found that, among preschoolers, a lower IQ was linked to a higher BMI. Those researchers also say environmental factors are at play, since the relationship between BMI and smart-aleckies was mediated by socioeconomic status.

You Have A Cat

A 2014 examine of 600 college student found that individuals who identified as “dog people” were more outgoing than those who identified as “cat people, ” according to a testthat measures personality and intelligence.

But guess what? Those same cat peoplescored higher on the part of the test that measures cognitive ability.

You Were Breastfed

2007 research is demonstrated that babies who are breastfed might grow up to be smarter kids.

In two examines, the researchers looked at more than 3,000 children in Britain and New Zealand. Those children who had been breastfed scored nearly seven phases higher on an Iq test but only if they had a particular version of the FADS2 gene.( That version of the gene was present in roughly equal numbers among kids who were and weren’t breastfed .)

Figuring out the exact mechanism of this relationship between FADS2, breastfeeding, and IQ will require further study, the scientists noted in their paper on the finding.

You’ve Use Recreational Drugs

A 2012 examine of more than 6,000 Brits born in 1958 observed a link between high IQ in childhood and the use of illegal drugs in adulthood.

“In our big population-based cohort study, IQ at 11 years was associated with a greater likelihood of using selected illegal drugs 31 years later, ” wrote researchers James W. White, Catharine R. Gale, and David Batty.

They conclude that “in contrast to most analyzes on business associations between childhood IQ and later health, ” their findings suggest “a high childhood IQ may inspire the adoption of behaviors that are potentially harmful to health( i.e ., excess alcohol consumption and drug use) in adulthood.”

You’re Left-Handed

Left-handedness used to be associated with criminality, and researchers are still unclear as to whether and why there are slightly more lefties among criminal populations.

More recent research associates left-handedness with “divergent thinking, ” a form of creativity that allows you to come up with novel ideas from a prompt at the least among men.

In her its consideration of a 1995 newspaper, New Yorker reporter Maria Konnikova writes 😛 TAGEND

The more differentiates the left-handed predilection in a group of males, the better they were at exams of diverging thought.

Left-handers were more adept, for instance, at combining two common objects in novel ways to sort a third for example, utilizing a pole and a tin can to make a birdhouse. They also excelled at grouping listings of words into as many alternate categories as possible.

You’re Tall

A 2008 Princeton study of thousands of people found that taller people scored higher on Iq test as kids and earned more money as adults.

The researchers write: “As early as age 3 before schooling has had a chance to play a role and throughout childhood, taller children perform significantly better on cognitive tests.”

You Drink Alcohol Regularly

Evolutionary psychologist Satoshi Kanazawa and colleagues found that, among Brits as well as Americans, adults who had scored higher on IQ tests when they were kids or teens drank more alcohol, more often in adulthood than those who had scored lower.

You Learned To Read Early
In 2012, researchers looked at virtually 2,000 pairs of identical twin in the UK and found that the sibling who had learned to read earlier tends to rating higher on exams of cognitive ability .

The study writers suggest that reading from an early age increases both verbal and nonverbal( e.g. reasoning) ability, as opposed to the other way around.

You Fret A Lot

A growing body of research is demonstrated that anxious someones may be smarter than others in certain ways, according to Slate’s coverage of several different analyzes on anxiety.

In one study, for example, researchers asked 126 undergrads to fill out questionnaires in which they indicated how often they experienced fret. They also indicated how often they engaged in rumination, or guessing continuously about the aspects of situations that upset them, as psychologist Dr. Edward Selby reported in Psychology Today.

Results goes to show that people who tended to worry and ruminate a lot scored higher on measures of verbal intelligence, while people who didn’t do much worrying or ruminating scored higher on exams of nonverbal intelligence.

You’re Funny

In one examine, 400 psychology students took intelligence tests that measured abstract reasoning abilities and verbal intelligence.

Then they were asked to come up with captions for several New Yorker cartoons, and those captions were reviewed by independent raters.

As predicted, smarter students were rated as funnier.

You’re Curious
In University of London business psychology professor Tomas Chamorro-Premuzi’s post for Harvard Business Review, he discussed how the curiosity quotient and having a hungry intellect attains one more inquisitive .

Regarding the importance of CQ, he wrote that, “It has not been as deep analyse as EQ and IQ, but theres some evidence to suggest it is just as important when it comes to managing intricacy in two major ways. First, individuals with higher CQ are generally more tolerant of ambiguity. This nuanced, sophisticated, subtle thinking style defines the very essence of intricacy. Second, CQ leads to higher standards of intellectual investment and knowledge acquisition over time, particularly in formal domains of education, such as science and art( note: this is of course different from IQs measurement of raw intellectual horsepower ). “

A Goldsmiths University of London studyfound that intellectual investment, or “how people expend their day and endeavor in their intellect, ” plays a major part in cognitive growth.

You’re Messy

A study published in “Psychological Science”by the University of Minnesota Carlson School of Management’s Dr. Kathleen Vohs revealed that working in an untidy room actually fuels creativity.

In the study, 48 participants were asked to come up with unusual uses for a pingpong ball. The 24 someones working in neat rooms came up with substantially less creative responses than the individuals working in cluttered rooms.

So if you are a pack rat, tell everyone you’re only fueling your sense of imagination and invention the next time someone tells you to clean up your act.

You Didn’t Have Sex Until After High School

High schoolers with higher IQs are more likely to be virgins than those with median or lower IQs, according to a study from the University of North Carolina Chapel Hill. The core sample looked at 12,000 teens from the 7th to the 12 th grade.

Not merely were the teens with the highest IQs more likely to be virgins, they were also least likely to kiss or hold hands with a romantic partner. A number of rationales have been put forward by the science blog Gene Expression to explain this gap, including suggestions that smart people possess lower sex drives, are risk adverse, or simply less able to find sexual partners.

You’re A Night Owl
One analyze published in the “The Official Journal of the International Society for the Study of Individual Differences” found that, when all other variables are factored out, night owls tend to beat out early birds in terms of intellect. It concluded that ethnographic proof indicates that “nocturnal activities” were rarer in the ancestral surrounding. That means that more intelligent someones are more likely to stay up late because smarter people are more likely to “espouse evolutionarily novel values.”

You Don’t Always Have To Try Hard

This isn’t to say that laziness is a sign of being smart. But it is fair to say that smart people simply don’t always have to try as hard as “strivers” who fight to build up their skills at least in certain fields.In an sentiments piece for The New York Times, psychologists David Z. Hambrick and Elizabeth J. Meinz quoth a Vanderbilt University study of highly intelligent young person.

The study tracked 2,000 people who scored in the top 1% of the SAT by the age of 13. Hambrick and Meinz wrote that, “The remarkable finding of their study is that, compared with the participants who were only in the 99.1 percentile for intellectual ability at age 12, those who were in the 99.9 percentile the profoundly gifted were between three and five times more likely to go on to earn a doctorate, procure a patent, publish an article in a scientific journal or publish a literary work. A high level of intellectual ability gives you an enormous real-world advantage.”

They to indicate that while striving to be smarter is commendable, there are certain innate abilities that can’t always be learned.
