Going to school much increases intelligence?

According to a study of men in Norway, spending a lot of time in school will increase intelligence. The study, which is part of a report by the US National Academy of Sciences, suggests that an additional year of schooling will increase IQ by nearly 4 points.

According to the BBC , the authors of the Norwegian Bureau of Statistics said that the increase in the number of school years has a huge effect on IQ in beginners. However, they do not know this applies to all children or only those in this study.

The relationship between the number of years of schooling and IQ has long been known. However, it is quite complicated to win a lot of time to go to school, because it is very likely that children who are born with high IQ will prefer to spend more time in school. .

Between 1955 and 1972, some local governments in Norway increased the number of compulsory school years from seven years to nine years, which means that students will finish high school at age 16 instead of 14 years old.

The effect of this increase in the number of years of schooling was recorded at the age of 19, when the military gave the male soldiers an IQ test. The researchers 'report said: ' There is a strange increase in the number of years of schooling and an increase in IQ at the same time as the educational reforms were conducted at that time. By taking advantage of the number of years of schooling brought about by comprehensive education reforms, this study can also detect a significant and statistically significant effect on high school years and IQ. in those who have just entered the adult stage in Norwegian men '.

Statisticians are also careful to avoid making too many conclusions when they acknowledge that this only works for Norwegian society or their education system at the time. However, they are discussing whether this will increase intelligence in adolescents.
