Why we get smarter: James Flynn @ TED

 Youtube Direktflynn

James Flynn erklärt auf der TED-Konferenz den nach ihm benannten Flynn-Effekt, den man bei IQ-Tests festgestellt hat und der belegt, dass die Menschheit immer intelligenter wird und kognitive wie kombinatorische Fähigkeiten immer schneller, größer und genauer werden. Mit jeder nachwachsenden Generation müssen die Tests neu justiert werden, grob alle 15 Jahre. Flynn erklärt das mit technologischem Fortschritt und komplexer werdenden Anforderungen. Superspannender Vortrag inklusive einem kleinen Ausflug in die Geschichte des Denkens.

In 1900, only 3% of Americans practiced professions that were deemed “cognitively demanding.” Today, 35% of us do, and we have all learned to be flexible in the way that we think about problems. In this fascinating and fast-paced spin through the cognitive history of the 20th century, moral philosopher James Flynn makes the case that changes in the way we think have had surprising (and not always positive) consequences.

Flynn argues that the effect comes down to three types of thinking we currently practice that we didn’t a century ago: “classification, using logic on abstractions, taking the hypothetical seriously,” as he puts it. In other words, kids are tested in school on their ability not just to recite facts, but to apply logic to abstract scenarios. These types of thinking are also demanded by our jobs, as cognitively demanding professions have risen in popularity and importance. “Some of the habits of mind that we have developed over the twentieth century have paid off in unexpected areas,” he says.
