Is IQ falling across the West?

From our UK edition

James Flynn's research on the eponymous Flynn Effect, showing massive gains in IQ in 14 nations in the course of the 20th Century, was leapt on by hard-working teachers, social policy wonks and dieticians. It rebutted claims that IQ was immutable and implied that ambitious interventions in families and schools could be effective. The gains Flynn discovered were so large, they suggested an average child would be regarded as a ‘genius’ by their great grandparents. However, Flynn has now changed his mind. In a speech he gave earlier this year at the International Society for Intelligence Research, and now published in Intelligence, a peer-reviewed academic journal, Flynn announced that this forward movement in IQ scores across the West has been slammed into reverse.
