Google makes people less intelligent

What political attitudes people have can also be read from their intelligence quotient - at least on average. In an American long-term study with 15,000 participants, young people who describe themselves as "very conservative" have an average IQ of 95 - five points below the average.

Your peers, who profess to be "very liberal" (in the American understanding of the word, that is progressive in the local understanding), have 106 IQ points.

For the psychologist Satoshi Kanazawa, who teaches at the London School of Economics, the data fit into the picture: intelligence allows people to behave differently from what evolution created them, he argues in Social Psychology Quarterly.

Their higher intellectual performance gives them the freedom to look for new ways in social coexistence. They are more likely to spend resources on people unrelated to them because of their intelligence and are more likely to be on state welfare that requires higher taxes.

Higher intelligence - new ways

Kanazawa's data fit well with a long-term British study: among the 6,000 or more people born in April 1970 and followed by researchers since then, the more intelligent are more likely to vote for Greens or Liberal Democrats than Conservatives or the Labor Party.

The University of Edinburgh psychologist Ian Deary quantified the difference in a 2008 study. The Green voters in the sample had a mean IQ of 108 as children, Conservative supporters 104 and Labor supporters 103. Non-voters and supporters of a right-wing extremist party were each below 100.

"These differences are not great, but they cannot be explained by chance either," says Detlef Rost, intelligence researcher at the University of Marburg. "To be progressive, people need cognitive performance. Whoever stays with the known doesn't have to think twice."

The London researcher Kanazawa explains the results in a similar way. With intelligence, people can turn away from traditions. He also includes the historically new idea of ​​not believing in a god. Among the Americans surveyed, the "not at all religious" had an IQ of 103 and the "very religious" an IQ of 97.
