A study performed at the University of Leipzig found that first-born children tended to be slightly smarter than their younger siblings. However, this is thought to be due to nurture rather than nature, as a higher social status in the family may account for the slightly higher IQ.
People who are left-leaning also tend to be slightly smarter, research has shown. A British study found that kids with higher intelligence scores were more likely to become liberal adults who vote for Democratic politicians, regardless of socioeconomic status.
Atheists are generally more likely to rely on concrete data and scientific evidence, whereas religion tends to require faith in the unknown, and often times religious beliefs are directly contradictory with scientific evidence.
That being said, of course there are plenty of very intelligent religious people and not-so-smart atheists!
It’s hard to think that anything good could come from having what is often a debilitating mental disorder, but evidence suggests that people who worry a lot are often times smarter than their happy-go-lucky counterparts.
AsSlateputs it, “a worried mind is a searching mind, and smarter people may have the cognitive agility to examine multiple angles of any situation, for better or worse.”
People who crack jokes constantly are more likely to be of high intelligence, according to a 2011 study performed at the University of New Mexico. The study had 400 students partake in assessments of verbal intelligence and abstract reasoning ability before writing captions for cartoons. The captions that were perceived as the funniest were written by the students who scored the highest on these assessments.
Contrary to popular belief, those with learning disabilities like dyslexia or ADHD are often times of very high intelligence, as there is generally a large discrepancy between the student’s actual ability and their performance in school. In fact, about one-third of students with learning disabilities are classified as “gifted.”
Swearing can actually be a sign of a good vocabulary and verbal fluency, which are traits associated with intelligence. So the next time someone criticizes you for dropping an F-bomb, just show them this page.
Good news for all of you night owls out there! Historically, humans have gone to bed and woken up with the sun, but evidence suggests that smart people go to bed later and wake up later as a subconscious defiance of the norm.
Sleeping in late might not be a sign of laziness after all.
That’s right, more intelligent people tend to question things, including their own intelligence, whereas unintelligent people tend to overestimate how smart they are. Smart people even tend to overestimate the IQs of people who are of the same intelligence as they are.
