A study from the University of Edinburgh found that up to 30% of people who wear glasses have high intelligence and carry genes predisposing them to poor vision. These are just a few of the studies devoted to people with high intelligence. Scientists and psychologists have devoted considerable time to studying the intelligence quotient (IQ) of people with high and low IQs. Some of the results are listed below, and they may shock you, as they reveal a lot about people with high intelligence.
1. Intelligent people are terrible leaders because they do not use transformational and instrumental leadership styles.

In a 2014 blog post, Forward Progressives, It was argued that President Obama was too smart for Republicans to understand because his long-term leadership style was out of sync with what Americans believed they wanted or needed, making him less effective. Research conducted by Antonikis of the University of Lausanne supported this theory. In a study of more than 300 leaders from 30 European countries, he found that while intelligence and good leadership are correlated, the more intelligent a person is, the less effective they are as a leader. This is because highly intelligent leaders don't use leadership styles that would endear them to their followers. However, intelligent leaders can be trusted to do the right thing in the long run, while less intelligent leaders simply can't be trusted to do the right thing. (source)
2. Intelligent people are able to quickly learn and eradicate social stereotypes.

Numerous studies have demonstrated a correlation between intelligence and attitudes toward others, but all of them have yielded conflicting results. Lik, Adam, and Freeman of New York University considered these studies too general and conducted their own study to determine that intelligent people are more likely to internalize and eradicate stereotypes about social groups, and this was confirmed. In one test, participants were told negative things about a person, which they readily believed. In a second test, they were told positive things about the same person, which they readily accepted. Participants discarded what they had previously learned and replaced it with new information, and the more intelligent the participants, the easier it was for them to internalize and eradicate social stereotypes.

3. Smart men, as a rule, have very beautiful wives.

Just as most women prefer to marry a man taller than themselves, they also tend to marry men smarter than themselves. A small study conducted by Dunkel of Western Illinois University and published in the journal« Evolutionary Behavioral Sciences"» , it was found that the more beautiful a woman is, the more intelligent her husband is likely to be. For this study, the researchers used data from the Wisconsin Longitudinal Study, which tracked and studied nearly 10,000 men and women for 54 years (1957–2011). The study also found that a man may be attractive, but it was his intelligence that determined how suitable he was as a partner for highly attractive women. The study also found that more intelligent men married highly attractive women, but this was likely largely due to the woman doing the matchmaking. (1, 2)
4. Very intelligent people tend to be less attractive.

A study conducted by researchers from the University of Western Australia found that the more intelligent a person is, the less attractive they are perceived by a potential partner. The study involved 383 participants, who rated people based on criteria such as kindness, appearance, intelligence, and "easiness to communicate." Although people rated potential partners highly for intelligence, if a person was deemed too intelligent, they became less attractive. Previous research shows that the more intelligent a person is, the less confident others feel, making them less attractive. If a person is also too easy to communicate with, others will perceive them as insecure and lacking ambition. (1, 2)
5. Scientists have found that people with high intelligence tend to live longer.

Scientists have found that more intelligent people live longer, but this is largely due to genes. The study, published in International Journal of Epidemiology, argues that intellectually developed people live longer because their genes make them smart, so they have a low mortality rate. The study, published in BMJ , The study, based on data from 32,229 women and 33,536 men, was conducted. All were born in 1939 in Scotland and, at age 11, took a standard intelligence test, which included 71 tasks testing verbal and nonverbal reasoning skills. The study continued with these same participants for 68 years, recording relevant data on death and age at death. The study found that more intelligent participants lived longer because they knew not to smoke or do anything harmful to their health. Thus, although social status, income, and a healthy lifestyle can influence lifespan, it appears that people with more intelligent genes live longer. (1, 2)
6. Smart people trust other people more than less smart people.

A study conducted by researchers at Oxford University shows that more intelligent people trust more easily than less intelligent people, and this may be due to two factors. First, the smarter a person is, the better they are at understanding people; and second, the smarter a person is, the better they are at assessing situations and possible outcomes to know who to trust and who not to. Their study is based on data analysis. General Social Survey ), which is held in the United States every two years. (1, 2)
7. Intelligent people tend to be sloppy, stay awake longer, and swear more often.

Studies have shown that the more intelligent a person is, the more likely they are to stay up late. Their brains are still working at full capacity, so sleep may not come as quickly. Is your desk always cluttered and you're too lazy to clean it? Research from the University of Minnesota shows that intelligent people are often preoccupied with more important things than organizing their desks. And if you swear a lot, it might be because you're very smart and have a rich vocabulary. (1, 2)
8. More attractive people are smarter. "Very attractive" women are, on average, about six IQ points smarter than "very unattractive" women.

This applies to men too. Satoshi Kanazawa's research shows that attractive people tend to be more intelligent than unattractive ones, and this could be because a) they have excellent genes, or b) an intelligent person married an attractive person, resulting in an even smarter and more attractive child. This is entirely possible, as attractiveness and intelligence can be heritable. The research goes further and shows that if you want to determine someone's intelligence without an IQ test, you can judge them by their attractiveness, and this will give you a similar result as judging them by their years of education. (1, 2)
9. Intelligent people feel happier when alone.

Norman P. Lee and Satoshi Kanazawa conducted research on the "savanna theory of happiness," which posits that we respond to circumstances in the same way our ancestors did because our psychological evolution is based on the needs of our savannah-dwelling ancestors. Their research revealed some surprising results, the most surprising of which was that more intelligent people are happier when alone. They prefer their own company to that of good friends because social interactions bring them less satisfaction. Perhaps the presence of others distracts them from more purposeful pursuits. If you are very comfortable in your own company and have a high IQ, what is the reason for this? (source)
10. Smart people have a great sense of humor.

Research consistently shows that the smarter a person is, the funnier they are. This is attributed to several factors, including a high IQ, high levels of creativity, and impressive reasoning and verbal communication skills. Albert Einstein is known for being incredibly funny. Comedians like Ellen DeGeneres and Trevor Noah are masters of satire, which means they are also very smart. And this great sense of humor isn't limited to just humor. Being able to understand and appreciate jokes, no matter how dark or subtle, is also a sign of high intelligence. A study by Greengross and Miller, researchers at the University of New Mexico, and Martin at the University of Western Ontario, proves that a sense of humor is a sign of strong cognitive abilities and good cognitive preparation. Their study involved a group of college students who were asked to complete a humorous task: creating profiles of people using basic information. The college students were then rated by other participants, and all were asked to take several tests of openness, sociability, conscientiousness, and general intelligence. Those who performed well on the general intelligence tests also scored the funniest on the humorous tasks they had been given earlier. (1, 2)
