The Reverse Flin Effect on IQ Scores

American IQ scores have rapidly dropped, proving the reverse flin effect. A Northwestern University shows a decline in three key intelligence testing categories. The study used an online survey style personality test called the Synthetic Aperture Personality Assessment Project to analyze nearly 400,000 Americans. Researchers recorded responses from 2006 and 2018 in order to examine how cognitive ability scores were changing over time within the country.
