Recently, a study conducted by social psychologists David Deng Ning and Justin Kruger of Cornell University provided data support for traditional IQ estimation. Research shows that there are 15 subtle signs that you are smarter than you think!
music lessons
Research shows that music can help children's thinking development. A study of 20 1 1 found that children aged 4-6 improved their scores in language intelligence tests after only one month of music lessons. A study led by Glenn Schellenberg in 2004 also found that the IQ of 6-year-old children who studied music for 9 months was significantly improved compared with those who took drama classes or did not take any courses. At the same time, a study led by Schellenberg on 20 13 shows that children with excellent grades are most likely to take music courses. In other words, music training may enhance the existing cognitive differences.
Brothers and sisters in the family
Studies have found that older brothers and sisters in families are usually smarter, which has nothing to do with heredity. Using militarized records, Norwegian epidemiologists examined the birth order, health status and IQ scores of nearly 250,000 men between 18 and 19, who were born between 1967 and 1976. The results show that the average IQ of the first-born baby in the family is 103, the second-born baby is 100, and the third-born baby is 99. At the same time, this difference is obviously not due to genetic factors, but to the psychological interaction between parents and children.
Thin body
breast feeding
Research in 2007 showed that breast-fed babies may be smarter when they grow up. In two independent studies, researchers studied more than 3,000 children in Britain and New Zealand. Breast-fed children score nearly 7 points higher in IQ tests, provided that they have a specific FADS2 gene (breast-fed and non-breast-fed children are roughly the same). The researchers pointed out that the exact mechanism of the relationship between fashionable breastfeeding and IQ needs further study.
Illegal drugs
In 20 12, a study on more than 6,000 Britons born in 1958 found that there was a link between high IQ in childhood and the use of illegal drugs in adulthood. The researchers said that the IQ at the age of 1 1 is related to the possibility of using illegal drugs after 3 1 year. Children's high IQ urges 1 to try behaviors that may be harmful to health in adulthood (that is, excessive drinking and taking Du products).
left-handed person
A recent study linked left-handedness with divergent thinking. For example, left-handed people are better at combining two objects into new things in novel ways (such as making birdcages with wooden sticks and tin cans), and they are also good at dividing words into as many categories as possible. This creativity enables them to put forward many novel ideas from a single question.
height
A study of thousands of people in Princeton in 2008 found that tall people scored higher in IQ tests. Researchers say that from the age of 3 to childhood, tall children perform better in cognitive tests.
drink
Satoshi Kanazawa, an evolutionary psychologist, found that among the British and Americans, adults who scored higher on IQ tests drank more alcohol as teenagers than those who scored lower.
Early reading
In 20 12 years, the researchers observed nearly 2000 pairs of identical twins in Britain, and found that brothers and sisters who learned to read earlier scored higher in the cognitive ability test. Researchers believe that reading from an early age will improve verbal and nonverbal (that is, reasoning) abilities.
Anxious
Anxious people may be smarter than others in some ways. The results of a study show that those who always worry and think repeatedly score higher in the language intelligence test, while those who don't worry or think too much score higher in the non-language intelligence test. Psychologists believe that thinking repeatedly or constantly will make them feel uneasy.
interest
In one study, scientists tested the abstract reasoning ability and verbal intelligence of 400 psychology students, and then asked them to propose subtitles for several cartoons of new york people, which were examined by independent evaluators. As predicted, the censors think smart students are more interesting.
curiosity
Individuals with high CQ (creative intelligence) are usually more tolerant of ambiguous things. With the passage of time, this meticulous and subtle way of thinking will bring a higher level of intellectual input and knowledge acquisition, especially in the formal education field, such as science and art.
muddled
A study by Kathleen Vohs of the Carlson School of Management at the University of Minnesota shows that working in an untidy room can actually stimulate creativity. In this study, 48 participants were asked to provide unusual uses of table tennis. People who work in clean rooms put forward much less creativity than those who work in messy rooms.
stay up late
Studies have found that people who like to stay up late tend to have better intelligence than those who like to get up early. Evidence shows that "nocturnal activities" are rare in the ancestral environment, which means that smart people are more likely to stay up late because smart people are more likely to "support the novel values of evolution".
make an effort
Smart people don't always work hard, at least in some fields. The study tracked 2,000 people whose SAT scores were in the top 1% when they were 13 years old, and found that these people were three times and five times more likely to get a doctorate, patent, publish articles in scientific journals or publish literary works than others. The results show that although hard work will make you smarter, some natural abilities cannot be acquired through study.
So, are you smart?
