The amount of hair on the body, liking to eat chocolate, drinking less alcohol, being left-handed… can be the factors that contribute to determining the intelligence of each person.
People often think that intelligence is a natural gift and not everyone has it. But that is a relative concept. Human intelligence is partly due to genetics, partly depends on the environment.
Here are the factors and actions that seem very ordinary, but there is an assumption that they have a big impact on the “intelligence” of each person…
For men, the amount of hair and body hair can tell how smart a guy is. The person who found this connection was Dr. Aikarakudy Alias . Instead of looking at the relationship between body hair and IQ, Alias focused on analyzing the social success of men.
According to him, students and intellectuals have more and thicker chest hair than other ordinary, manual workers. At the same time, among students, the excellent students were much more hairy relative to the average students.
Of course, Alias’s research is still met with mixed opinions. In addition, he has not made general conclusions about human intelligence in general, including women, but only at the level of research on men.
One thing is for sure, intelligence depends on the social environment a child is born and raised. According to experts, one of those factors is birth order. A study by experts from the University of Oslo, Norway published in the journal Science concluded that the first child has a 2-3 point higher IQ than the second child.
The responsibilities and expectations placed on the shoulders of the eldest son are always heavier.
Their study was conducted on 240,000 Norwegian men, aged 18-19 years, between 1985 and 2004. Accordingly, the average IQ of the eldest child is 103.2 points, 2 points higher than the second child and 3 points higher than the third child.
Explaining this phenomenon, scientists explain that the problem is due to the way parents behave with their children. The oldest children are often treated as the future “master” of the family, given more responsibilities and expectations, so they often have a higher IQ than the younger children.
The most obvious proof is that according to Norwegian experts, in families where the first child dies, the next second child has an IQ that is almost equal to that of their deceased brother or sister.
For those who love sweet, chocolate is an attractive dish not to be missed. However, few people know that the frequency of eating chocolate is closely related to intelligence in each individual.
Chocolate is inherently a food good for human health. In the right doses, it improves the psychological well-being of patients with mild cognitive impairment, a symptom of senile dementia. This stimulated scientists at Columbia University to study the connection between the human brain and eating chocolate.
According to the team’s findings, published in the New England Journal of Medicine, “when we compare chocolate consumption and the number of Nobel laureates per capita, they are strongly related.” Specifically, Switzerland is the country that consumes the most chocolate in the world and surprisingly, it is also the country with the most Nobel laureates in the world.
A few good examples can be mentioned in the case of Christopher Pissarides – who won the 2010 Nobel Prize in economics or Robert Grubbs who won the 2005 Nobel Prize in chemistry. Both are chocolate followers, both eating this food. everyday and almost all spare time.
However, this connection is still controversial among experts. Because Sweden is the country with the second highest number of Nobel laureates in the world, yet this country consumes chocolate only at an average level. In addition, there are many scientists who do not like to eat chocolate but still have success with the Nobel Prize like Rolf Zinkernagel.
Religious beliefs and intelligence are inherently considered unrelated. However, through recent studies of scientists, the truth is completely different.
From a national perspective, it is estimated that the highest IQ is in countries that follow atheism , that is, do not believe in gods or gods. On a personal level, a 2008 study found that people who don’t believe in religion are smarter.
In intelligence rankings, it was found that atheists often appear at the top, followed by agnostics, liberals and finally religious fundamentalists.
The brain is divided into 2 hemispheres and is of unequal size. In humans and many other mammals, one hemisphere will grow and become larger in size, which is what causes us to be different handed. Some studies have shown that this is related to intelligence, with left-handed people often scoring higher and completing faster on IQ tests than right-handed people.
Eccentric people often have strange behaviors related to social norms. However, history has proven that the source of creative knowledge is eccentricity, researcher Montaigne has said: “Obsession is the source of genius and madness” , possibly eccentrics. usually have a corresponding intelligence.
A study by evolutionary psychologist Satoshi Kanazawa has found a link between homosexuality and intelligence. Homosexuality is not a trait of intelligence in itself, but Kanazawa’s findings suggest that people who have had many same-sex partners may become more intelligent. They often score high on intelligence tests. Children showing signs of homosexuality are likely to turn to intellectual pursuits, and may feel a greater urge to strive for achievement in the field in which they are accepted.
This is perhaps the craziest notion that has its roots in antiquity. Many studies show that there is a strong connection between bipolar disorder and the ability to create both some of the world’s artistic and scientific talents. A Swedish researcher compared the links between academic performance and mental health among students, and found that students with high academic performance were twice as likely to develop bipolar disorder. 4 times in my life.
High-achieving students are four times more likely to develop bipolar disorder in their lifetime.
According to several studies in children, certain traits in their adulthood have shown a link between alcohol and intelligence. You can predict your child’s alcohol use based on their intelligence. More intelligent children drink less alcohol than other less intelligent children.
