Get to know smart people through quirky factors

The amount of hair on the body, like eating chocolate, drinking less alcohol, left-handed . can be the factor that contributes to determining the intelligence of each person.

It is often said that intelligence is a godly nature and not everyone has. But that is a concept that is relative. Smart people are partly due to genetics, partly dependent on the environment.

Here are the elements and actions that seem to be very ordinary, but have the assumption that they have much impact on the 'intelligence' of each person .

1. Each person's intelligence depends on . the amount of hair on the body

For men, the amount of hair and hair on the body can tell the guy how smart he is. The one who discovered this connection is Dr. Aikarakudy Alias . Instead of looking at the relationship between human hair and IQ, Alias ​​focuses on analyzing the level of male social success .

According to him, the students and intellectuals have more and more chest hair than those who do manual, normal work. At the same time, among the students, the excellent students are also much thicker in relation to the average students.

Of course, Alias's research still faces mixed opinions. In addition, he has yet to make a general conclusion about human intelligence in general, including women, but only at the level of research on men.

2. "The eldest or the second?" decide intelligence

One thing is for sure, intelligence depends on the social environment a child is born to grow up. According to experts, one of the factors is the birth order. The study by experts from the University of Oslo, Norway in Science magazine concluded that the eldest child had an IQ score of 2-3 points higher than the second.

The responsibilities and expectations put on the shoulders of the eldest son are always heavier.

Their study was conducted on 240,000 Norwegian men, aged 18-19, during the period 1985-2004. Accordingly, the average IQ of the eldest child is 103.2 points, 2 points higher than the second child and the third child 3 points.

Explaining this phenomenon, scientists explain that the problem is due to the behavior of parents with their children. The eldest is often treated as the 'owner' of the future of the family, is given more responsibilities and expectations so often has a higher IQ than the second child.

The most obvious proof is that according to Norwegian experts, in the families where the oldest child died, the next second child with an IQ is almost on par with his or her late sister.

3. Smart people who eat a lot of chocolate

For those who are sweet, chocolate is an attractive dish that cannot be missed. However, few people know, the frequency of eating chocolate is closely related to the intelligence of each individual.

Chocolate is a good food for human health. In the right dosage, it improves the psychological condition for patients with mild cognitive impairment - a symptom of old age dementia. This stimulates Columbia University scientists to study the connection between the human brain and eating chocolate.

"When we compare chocolate consumption and the number of Nobel laureates averaging per capita, we see that they have a close relationship , " according to the results of a study published in the New England Journal of Medicine. Specifically, Switzerland is the most chocolate consuming country in the world and surprisingly, this is also the country with the most Nobel laureates in the world.

Some good examples are the case of Christopher Pissarides - the 2010 Nobel laureate or Robert Grubbs who won the Nobel Prize in 2005. Both are believers of chocolate, eating this food. daily and almost every spare time.

However, this relationship is still controversial among experts. Because Sweden is a country with the second highest number of Nobel laureates in the world, this country consumes chocolate only at an average level. In addition, there are many scientists who do not like to eat chocolate but still get success with Nobel prizes like Rolf Zinkernagel.

4. People with high IQ do not believe in religion

Beliefs in beliefs and intelligence are considered unrelated. However, through recent research by scientists, the truth is completely different.

From a national perspective, it is statistically possible that the highest IQ is in atheist countries , ie, do not believe in gods or gods. From a personal perspective, a 2008 study showed that the more people who did not believe in religion were more intelligent.

In the intelligence rankings, it is noticed that atheists often appear at the top, followed by a list of agnostic, free believers and eventually religious believers.

5. Left-handed

The brain is divided into 2 hemispheres and uneven size. In humans and many other mammals, one side of the hemisphere will grow and be larger in size, which is what makes us different. Some studies have shown that this is related to intelligence, left-handed people often have higher scores and complete faster on IQ tests than right-handed people.

6. Eccentric people

Humans often have strange behaviors related to social norms. However, history has proved that the source of creative knowledge is eccentricity, researcher Montaigne said: "Obsession is a source of genius and madness" , maybe eccentric people Usually have a corresponding intelligence.

7. Homosexuality

A study by evolutionary psychologists Satoshi Kanazawa found a link between homosexuality and intelligence. Not that homosexuality itself is a feature of intelligence, Kanazawa's research results suggest that people who have multiple homosexual partners may become smarter. They often have high scores in intelligence tests. Children who show signs of homosexuality may turn to intellectual pursuits, and may feel a greater urge to strive for achievement in the field they are accepted.

8. Bipolar disorder

Perhaps this is the craziest notion that originated in ancient times. Many studies show that there is an intimate relationship between bipolar disorder and the ability to create both artistic and scientific talents around the world. A Swedish researcher compared the academic performance and mental health outcomes of students, who found that high-achieving students were at increased risk of bipolar disorder. 4 times in life.

Students with high academic results are at four times the risk of bipolar disorder in their lives.

9. Drink alcohol

According to some studies in children and some characteristics in their maturation process, there is a link between alcohol and intelligence. You can predict your child's alcohol use based on their intelligence.The more intelligent a child is, the less alcohol they drink than the other less intelligent children.
