Psychoeconomics: globalization, markets, crisis - стр. 45

Each psycho-type has its own type of intelligence. It begins to be realized more and more in modern psychology. With this initial reference it is clear that with a change in psyche of people along with the changing cycles of solar activity the results of psycho-diagnosis will also vary by means of one and the same intelligence tests. This thesis fully supports the Flynn effect and the data on its refinement. The essence of the effect is in gradual increasing of the levels of intelligence quotient (IQ) of people in different countries within decades. The publication of data on this was in 1984 (The mean IQ of Americans: Massive gains 1932 to 1978 in the magazine “Psychological Bulletin”). The explanation of this fact with the genetic evolution of humanity that appears to be the “growing clever” is not tenable, since this effect affects the decades and not the change of generations.

The new tested ones with the time difference of 10 or more years since 1932 in the United States (these are the years when resonants came to power), showed higher scores on the old tests. According to Flynn, from 1934 to 1978 the IQ of the average person in the United States increased by 15 points, in other words it grew by 3 points per decade. We should not that in respect to the United States it was the time of the activity of the resonants and postresonants.

There are lots of facts on this matter. And they do not allow us to doubt in accuracy of the conclusions of Flynn, but at the same time they show the historical boundaries of this effect in developed countries.

So, in 2004 the Norwegian scientists (Jon Martin Sundet, et cetera.) from the University of Oslo published in the journal «Intelligence» the article about the evolution of the test results of the conscripts in the period from 1950 to 2002 in collaboration with colleagues from the psychological service of the Norwegian armed forces. According to them during the first two decades Flynn effect took place as even more pronounced than that recorded by Flynn himself. But according to these scientists it was found that the rate of increase in IQ 70-80 years began to slow down noticeably, and by the mid-90's the growth of IQ stopped at all. As for some individual figures, namely, the test results of arithmetic skills began slowly but steadily decline since that time.

The works of Tisdale and Owen conducted in 2005 and again in 2008 the showed that the results of IQ tests of the Danish conscripts grew from 1959 to 1979 by 3 points per decade, and from 1979 to 1989 they grew by only 2 points, from 1989 to 1998 by 1,5 points, but for the period from 1998 to 2004 they decreased by the same 1.5 points. http://ru.wikipedia.org/wiki/Эффект_Филинна
