The facts you don't know about IQ

Poverty makes it difficult for you to achieve good results in IQ tests. Meanwhile, the average IQ of a country also affects GDP per capita.

According to Business Insider on May 23, although researchers have not been able to determine the level of IQ affecting each person's success, they have discovered that many factors in life can affect IQ and reverse. again.

1. Breastfed babies can achieve higher IQ

According to a small study in 2016, scientists tracked 180 breastfed babies or formula milk during the first 28 days of their birth. At the age of 7, breastfed babies performed better in cognitive tests.

2. Children under 3 years of age eat a lot of harmful things that are worse in IQ tests

Children under 3 years of continuous eating harmful foods (high sugar, high fat) are less effective than their peers in Wechsler's intellectual measurement tests (WISC), performing five of them 8 years old. Diets rich in vitamins and minerals have the opposite effect.

3. Material deprivation can lead to poor results in IQ tests

A small 2013 study at Princeton University (USA) pointed out that "a person's cognitive function is reduced by trying hard to deal with a low-cost situation, such as avoiding paying bills. or cut costs ".

4. Relationship with GDP per capita

If a country's average IQ increased by 1 point, per capita GDP increased by $ 229 and could rise to $ 468 for each additional point.

A 2011 study of Psychological Science found that when surveyed in 90 countries, " the intelligence of people, especially the most intelligent 5%, contributed greatly to the country's economic power . " Intelligence is determined by many factors such as science and technology test scores, Nobel prizes .

In the 2015 book Hive Mind, economic professor Garett Jones also argued that a nation's IQ is a basic indicator of economic success.

5. There may be a link between intelligence and life expectancy

Many studies in the world show the relationship between intelligence (measured by cognitive tests) and human lifespan. There is even a field of study called cognitive epidemiology to understand this relationship. Specifically, smart people are said to be more likely to live longer than others. However, this has not been thoroughly proven.

6. Intellectuals related to social skills

IQ may be related to EQ (emotional intelligence), according to a 2013 study published in Social Cognitive & Affective Neuroscience.

Aron Barbey, a neuroscientist at the University of Illinois, co-author of the study, said: "Intelligence in a broad sense depends on basic cognitive ability such as concentration, memory, language. But it It also depends on the ability to interact with others. "
