- [Narrator] Hey, Psych2Goers.
How intelligent are you?
There are some interesting signs
that someone is likely more intelligent than others,
ones you may be surprised to hear.
According to the research studies mentioned in this video,
having a messy room or being a chronic worrier
could be subtle signs that you're actually more intelligent
than you might presume.
There are plenty more unique signs.
Do you have any of them?
Watch 'til the end to find out.
Here are six signs you're likely more intelligent
than you think.
Number one: You learned to read at a very early age.
How young were you when you learned to read?
In a 2014 study, researchers examined 2,000 pairs
of identical twins in the UK.
The twin that learned to read at an earlier age
tended to perform better on tests of cognitive ability.
Authors suggest that learning how to read at an earlier age
improves the child's verbal and nonverbal abilities.
In the study, they explain that early remediation
of reading problems
might not only aid in the growth of literacy,
but also may improve more general cognitive abilities
that are of critical importance across the lifespan.
Who know reading "Cat in the Hat" so early
could change your life for the better?
Number two: You're a musician.
Do you play a musical instrument
or maybe you had lessons as a kid?
Well, it's likely aided you long-term.
Several studies have suggested that music assists
in the development of children's minds.
A 2004 study by Glenn Schellenberg
examined a group of six-year-olds
that took nine months of voice or keyboard lessons
and compared them to groups that took drama lessons
or no lessons at all.
According to the study, they found that
compared with children in the control groups,
children in the music groups exhibited
greater increases in full-scale IQ.
Another study published in 2011,
found that even music lessons in a short amount of time
can improve verbal intelligence in children four to six
as compared with children who participated
in a program for visual art.
The study states that after only 20 days of training,
only children in the music group
exhibited enhanced performance
on a measure of verbal intelligence,
with 90% of the sample showing this improvement.
These improvements in verbal intelligence
were positively correlated
with changes in functional brain plasticity
during an executive function task.
Our findings demonstrate that transfer
of a high-level cognitive skill
is possible in early childhood.

Number three: You worry often.
Do you worry (pausing) a lot?
In a 2015 study, researchers had 126 undergraduate students
complete questionnaires indicating how much they worried,
ruminated on worrying thoughts
and thoughts about scenarios that upset them.
What did they find?
Well, students who often spent time worrying
and ruminating on thoughts held a high score
in measures of verbal intelligence.
Those who didn't worry as much
scored higher in nonverbal intelligence.
Number four: You wear eyeglasses.
Are you wearing glasses right now?
Well, you may just be more intelligent than you think.
According to a 2018 study from the University of Edinburgh,
if you're smart, you're more likely
to have bad eyesight genes.
Yeah, if you're intelligent,
you're 30% more likely to have those bad eyesight genes.
So, if you do, it means you'll likely need to be wearing
a pair of glasses as you're watching this;
well, depending on how close you are to the screen.
Are you near-sighted or far-sighted?
Number five: You enjoy being alone more than socializing.
Are you an introvert?
Do you favor the days where you get to spend the evening
in pleasant solitude alone in your room?
Well, you're likely one smart cookie.
Researchers Norman P. Li and Satoshi Kanazawa
had 15,000 individuals 18 to 28 take a survey and IQ test.
The individuals who were highly intelligent
were found to be not as happy with their lives
the more frequently they socialized.
The study states, importantly,
the main associations of life satisfaction
with population density and socialization with friends
significantly interact with intelligence.
And in the latter case, the main association is reversed
among the extremely intelligent.
More intelligent individuals experience
lower life satisfaction
with more frequent socialization with friends.
And number six: You're messy.
Are you messy?
How messy?
Do clothes lie scattered about your floor?
Dust across your countertops?
According to a 2013 study from the University of Minnesota,
subjects had to come up with some unconventional uses
for a ping pong ball.
The ones with the messier rooms had the most creative ideas,
while those who were neat
were not as creative in their responses.
So, are you smarter than you think?
