In general, an IQ score is defined with a median and mean of 100. Scores above 130 are labeled as above average or “very superior,” while scores under 70 would be considered below average or labeled as “borderline impaired.” Most people have an average IQ between 85 and 115.
High IQ people are likely to be flexible, curious, and open-minded. But because personality traits can vary widely among people with high IQ, there aren't necessarily clear outward signs that indicate that someone has high IQ.
Key Facts:
Researchers discovered that people with higher IQs are quicker when solving simple tasks but slower when dealing with complex problems. The research was based on personalized brain simulations of 650 participants from the Human Connectome Project.
However, intelligence has drawbacks too. For example, studies have found that higher IQ is associated with more and earlier drug use. Studies have also found that higher IQ is associated with more mental illness, including depression, anxiety, and bipolar disorder.
IQ peaks and stops increasing at around 20 years of age and then is mostly fixed for life. IQ peaks at around 20-years-old and later effort will not improve it much beyond this point, research finds.
Talking to yourself, it turns out, is a sign of genius. The smartest people on earth talk to themselves. Look at the inner monologues of the greatest thinkers. Look at poetry!
Lack of Sleep Won't Make You Smarter
A study published in the journal Sleep found that sleep is important for cognitive performance and that individuals who have better sleep quality tend to have higher intelligence scores.
Furthermore, people with depressive symptoms tended to score lower in exercises of intelligence and cognitive thinking than people with normal, healthy mental conditions. In short, there's also research to suggest that with a low IQ and a lower intelligence comes a higher risk of depression.
Intelligent people tend to appear quiet because they are natural observers. They are listening and watching what's going on around them.
Intelligent people love working alone because it allows them to be in tune with their inner creative selves. They can introspect different fields and even think out of the box. When there are so many people around, it is difficult to think quietly and creatively because there's chaos all around.
According to research, you sound more intelligent if you speak relatively slowly. (Think of it as the Jeff Goldblum effect.) Speaking at a measured pace makes you seem smarter--as if your words are better thought-out (even if they aren't).
Elon's IQ is estimated to be around 155, while Albert Einstein's is 160. With such a slight margin, Musk is undoubtedly an incredibly smart person. Who is the smartest person on earth in 2022? Born in 1975 in Adelaide, Australia is a mathematician, Terence Tao with an IQ score of 230.
What age is your mind the sharpest? The human brain attains peak processing power and memory around age 18. After studying how intelligence changes over time, scientists found that participants in their late teens had the highest performance.
Yes. However, there is heavy debate over exactly how IQ and intelligence change with age. Studies have demonstrated that a person's fluid intelligence tends to decrease starting in their late 20s, while their crystallized intelligence tends to increase as they grow older.
Faces that are perceived as highly intelligent are rather prolonged with a broader distance between the eyes, a larger nose, a slight upturn to the corners of the mouth, and a sharper, pointing, less rounded chin.
People who have genius traits tend to think about problems and concepts in a much more dynamic way. As a result, they are unlikely to accept information and facts on face value. Instead, they will want to defy and test conventional thinking.
Positive signs of high intelligence. Research shows that the signs of intelligence are usually good memory and thinking ability, good attitude and hard-working nature, general and tacit knowledge, language proficiency and reasoning, decision-making, trust, creativity, achievements, good intuition, and problem-solving.
ADHD can make completing tasks such as school work, homework, or work projects much more difficult. However, there is no clear link between ADHD and IQ. A person may have a high, average, or low IQ score and also have ADHD. ADHD may cause a person to interrupt in class or perform poorly on tests.
Research has shown that there is a high correlation between being intelligent and socially anxious. The higher your IQ, the higher the chance your social apprehension is higher than usual. Of course, that doesn't mean that your social anxiety should be classified as a disorder.
Brains and life span
For example, a study of people born in Scotland that was published in 2001 in the British Medical Journal found that the higher people scored on an IQ test at age 11, the more likely they were to survive to at least age 76.
Research suggests that highly intelligent people get bored easily and spend more time thinking, behaviour that comes across as 'laziness'. A study by the Florida Gulf Coast University looked at a group of 'thinkers' and 'non-thinkers', studying their activity levels over the course of a week.
