The Power of Attention

The Flynn effect, named after the work of Kiwi intelligence researcher James Flynn, observed rapid rises in intelligence quotient at a rate of about three IQ points per decade in the 20th century. But new research suggests these heady boom days are long gone. An analysis of some 730,000 IQ test results by researchers from the Ragnar Frisch Center for Economic Research in Norway reveals the Flynn effect hit its peak for people born during the mid-1970s and has significantly declined ever since.
