Since the beginning of the 20th century, scientists have been measuring IQ. Since then, it has been steadily rising in highly developed countries - this development is called the Flynn effect.

Reasons for the steady rise in the 20th century have been suggested to be a richer and healthier diet, improved medical care, and a higher level of education.

A recent study by Norwegian scientists comparing IQ tests of more than 700,000 Norwegian men born between 1962 and 1991 was published. In 1962 births the IQ was 99.4, in those born in 1975 102.3, in 1989, average IQ fell below 100 again.

Similar studies from Denmark, Great Britain, France, Netherlands, Finland and Estonia confirm this trend.

To date, the scientists can only speculate on the reasons why the IQ has dropped again in recent years. They suspect environmental factors such as increased media consumption (video games, the Internet, etc.), less reading and unhealthy diet in the form of fast food.

Because we've rewired our brains for shallow and scattered thinking, and not complex and deep thought. This is mostly from a movement away from the printed word which is consumed in a linier manner, and towards hyper-text which is non-linier. The prevalence of video is also a factor.
