Campus Reform | Historic decline in IQ could stem from poor education, study shows

• A recent study suggests that, for the first time in nearly 100 years, Americans’ average intelligence quotient (IQ) is declining.
• The professors who authored the study theorize that the quality of education could play a role in reversing the IQ gains enjoyed by previous generations...
• Professors from Northwestern University in Evanston, Ill., and the University of Oregon in Eugene explain the Flynn effect: starting in 1932, average IQ scores increased roughly three to five points per decade. In other words, “younger generations are expected to have higher IQ scores than the previous cohort.”
