TEDtalk: James Flynn: Why our IQ levels are higher than our grandparents
“Think how different America would be if every American knew that this is the fifth time Western armies had gone to Afghanistan to put its house in order. And if they had some idea of exactly what had happened on those four previous occasions. And that is they had barely left and there wasn’t a trace in the sand”
James Flynn, in this resounding and brilliant TEDtalk, calmly and patiently makes a very clever point about exactly why IQ scores have been improving. He astutely cites our increasingly common ability to apply logic to abstraction; to deal sincerely in the hypothetical and casts this concept into a very impressive talk.
