It’s not just you. People really are getting dumber, according to a new study.

Research published online in the journal Intelligence on Thursday claims the IQ of people in Western nations has fallen by an average of 14.1 points over the past century.

Scientists in Europe used visual response times recorded in Western studies from 1889 to 2004.

The idea is, the faster a person reacts, the smarter you supposedly are.

"Simple reaction time measures correlate substantially with measures of general intelligence and are considered elementary measures of cognition,” wrote researchers Michael A. Woodleya of Vrije Universiteit in Brussels, Jan te Nijenhuisc of the University of Amsterdam and Raegan Murphy of the University College Cork in Ireland.

Their findings showed a decline in general intelligence of 1.23 points per decade.

So why are we supposedly getting dumber?

Previous research has found that women of higher intelligence are having fewer children, meaning women of lower intelligence are driving population growth, according to the study.

Over time, experts say, that would affect the average IQ of a population.

"Victorians were cleverer than modern populations, using high-quality instruments, namely measures of simple visual reaction time in a meta-analytic study. Simple reaction time measures correlate substantially with measures of general intelligence (g) and are considered elementary measures of cognition."

 

Not buying it, the means to measure reaction time has undoubtedly improved over the listed time making the data suspect.
