You may be smarter than you've ever thought, though the fact that no one can really measure one's intelligence. Yes, some tests, studies, and studies have been done to find out the truth of one's high intelligence or IQ.
A person's intelligence is usually seen from how the person receives information, the capacity to use his logic, to understand, to keep himself, creativity, and to learn something to solve problems. However, there are some signs of high intelligence or IQ that you never know,
1.Mental illness
A study found an association between certain proteins with memory and curiosity was associated with bipolar disease and schizophrenia. Even other studies suggest that a person's ability to know complex mathematical equations and information with rapid processes can also put the person at risk for other mental illnesses.
2.Swearing
If you find yourself cursing more often than others, this does not mean something bad, science says the opposite. In a study published in Language Studies found that people who cursed often had a larger vocabulary, associated with higher intelligence or IQ, than those who never swore.
3.Taking risks
A study in Finland found that people who are open to new challenges and not afraid to take risks tend to be intelligent people. The study used a driving simulation and found that participants who made risky decisions during the test had more white matter, brain areas associated with cognitive function.
4.Lazy
A study from Florida Gulf Coast University found that intelligent people tend to be more lazy, because they have a long attention span. People who have bigger brains feel they do not have to keep doing something, they prefer to sit and think.
5.Birth order
Almost everyone understands that the eldest child in a family tends to be the one who can get anything, because they get great attention from the parents.
A study found that older children tend to have more rules to follow and more intense scrutiny, especially in terms of homework.
6.Restlessness
A study at Suny Downstate Medical Center, New York found that people with high IQ tended to be more anxious. Because you are constantly thinking about things, situations, and seeing the past as something that can affect your future. However, you are also very good at solving problems, critical thinking, and abstract reasoning.
