DNA and IQ: The Genetic Apocalypse By Brian Simpson

     DNA tests for IQ are fast approaching, but these tests may not be flattering for most people once they realize that they are not supper-geniuses but… morons:

     Now, you tell me how intelligent it is to have a URL that long! Surely they can shorten something? Didn’t man walk on the moon, or was that a conspiracy to? Anyway, IQ genetic testing will fast reveal that IQ is now in free fall, as humanity seems set to revert back to caveman savagery, although, in despair perhaps I am exaggerating a wee bit:

“A new study, conducted by Norwegian scientists, shows that IQ scores of today’s young people are in decline, putting an end to the post-war trend of rising intelligence. After the Second World War young people’s IQs were steadily rising. It was dubbed the Flynn effect after New Zealand intelligence researcher James Flynn. This phenomenon saw average IQ scores rise about three points per decade. But researches from the Ragnar Frisch Centre for Economic Research in Oslo say the Flynn effect is now past its peak. In a paper, published in the PNAS journal, Norwegian scientists Ole Rogeberg and Bernt Bratsberg analyzed the data from standardized IQ tests of about 730,000 men, born between 1962 and 1991, who underwent mandatory IQ tests to join the national service.

The study revealed that the IQ points of those tested peaked among those born in 1975, while people born in 1991 scored five points lower. According to the scientists, this shift could be due to many factors, including the way children are brought up and educated. For example there is less drilling in subjects like mathematics and languages and the total amount of time spent watching television or using technology has increased.
However, Dr Ole Rogeberg emphasized low IQ should not necessarily be interpreted as stupidity, but rather children adapting to the new reality of digital technology, skills that cannot be so easily accessed or evaluated by a standardized IQ test.”

     Whether this is genetic or environmental, and at this site we have had articles documenting the ill effects of pesticides on IQ:

     The fact remains, that intelligence is on the way down. Society may become ultimately too complex for the primitives of the future to manage. Someday, they may look with wonder at the decaying ruins where they live, and wonder whether Gods made these cities. Strange devices with funny material will be worshipped as religious icons. It is what happens when people become world weary and lazy from over-civilisation and too much material comfort.
