They include quick learning, interest in unique topics, and the ability to process information fast, among others. Some other habits or behaviors that may indicate a high level of intelligence or genius in an adult are: Tendency to have slightly cluttered living areas and workspaces. Fluency in taboo or " swear" words.
While there are many signs to indicate someone may be highly intelligent, the most common are a pleasant attitude and hardworking nature, excellent memory and recall capacity, good decision-making and problem-solving skills, high curiosity, good language proficiency, and high emotional intelligence.
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.
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.
The faces that look high IQ vs low IQ
“In both sexes, a narrower face with a thinner chin and a larger prolonged nose characterizes the predicted stereotype of high-intelligence, while a rather oval and broader face with a massive chin and a smallish nose characterizes the prediction of low-intelligence.”
Intelligent eyes seem to be for some reason more glossy and reflective than "average" eyes. While some people may look around by rotating their head, intelligent people tend to dart back and forth, as if they were looking between multiple objects.
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.
Early twin studies of adult individuals have found a heritability of IQ between 57% and 73%, with some recent studies showing heritability for IQ as high as 80%. IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults.
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.
“The higher an individual's IQ, the more likely the person is to fit the characteristics of a sensitive person.” This correlation has been observed across a wide range of fields, from the arts to science to business.
Studies have also found that higher IQ is associated with more mental illness, including depression, anxiety, and bipolar disorder.
While they might have high standards and big picture concerns, research shows that people with high IQs are actually more likely to be happy; data from the research showed that people with the highest IQs were much happier than those with the lowest IQs.
Empirical evidence suggests that especially parental education, parental income, and maternal IQ are important predictors of 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.
In short, it is supposed to gauge how well someone can use information and logic to answer questions or make predictions. IQ tests begin to assess this by measuring short- and long-term memory. They also measure how well people can solve puzzles and recall information they've heard — and how quickly.
They inquire about everything, including themselves
Asking questions is a more fundamental aspect of intelligence. A person with intelligence doesn't hesitate to ask questions that others wouldn't even dare to ask or are frightened to doubt a thing.
They successfully start each of their conversations with the right tone and energy. Smart people make eye contact, they pay attention to their body language, they ask smart questions, and they give compliments. They also make you laugh, they really listen, and they tell a great story.
What screams "highly intelligent person"? They will have unusual, deep, or specialized interests and hobbies you don't typically see people having. This is because they are highly curious about how the world works. They may be very quiet, especially if they possess advanced vocabulary.
Geniuses think productively, not reproductively
They tend to come up with many different responses, some of which are unconventional and possibly unique. Leonardo da Vinci believed that to gain deep knowledge about a problem, you have to learn how to restructure it in many different ways.
Definitions of genius in terms of intelligence quotient (IQ) are based on research originating in the early 1900s. In 1916 the American psychologist Lewis M. Terman set the IQ for “potential genius” at 140 and above, a level exhibited by about 1 in every 250 people.
