We Are All Getting Dumber, New Science Proves, and No One Is Sure Why | Inc.com
It probably shouldn’t worry us if some pocket of the population saw a decline in IQ as things like education and diet affect IQ and these factors can vary from one group or time to another. But according to this new study it doesn’t appear to be some small segment of the population whose IQ is going down. It appears to be the entire nation of Norway.
When scientists from the Norway’s Ragnar Frisch Centre for Economic Research analyzed some 730,000 IQ tests given to Norwegian men before their compulsory military service from 1970 to 2009, they found that average IQ scores were actually sinking. And not just by some miniscule amount. Each generation of Norwegian men appear to be getting around seven IQ points dumber.
