Online Tests Suggest IQ Scores In US Dropped For the First Time In Nearly a Century
A group of psychologists, two from Northwestern University and the third from the University of Oregon, has found via online testing that IQ scores in the U.S. may be dropping for the first time in nearly a century. Phys.Org reports: In this new effort, the researchers studied the results of online IQ tests taken by adults participating in the Synthetic Aperture Personality Assessment Project over a 12-year period. They found that IQ scores have dropped for all age groups, regardless of gender. They also found that the steepest declines were among young people. They also noted that while a few skills, such as spatial reasoning, were better than previous generations, other skills, such as problem solving, numerical series assessments and verbal reasoning, had all grown worse.

The researchers did not conduct any research to try to explain the drop, but suggest it might be linked to changes in the education system. They also did not address the controversial issue of the accuracy of IQ test scores in general as a means of measuring a person’s intelligence. The paper has been published in the journal Intelligence.
