James Flynn

James Flynn was a cognitive scientist best known for discovering the "Flynn Effect," which shows that average IQ scores have increased steadily over the past century across many countries. This suggests that people are, on average, becoming better at problem-solving and reasoning over time, likely due to improvements in education, nutrition, and environment. Flynn's work highlights the importance of measuring intelligence accurately and understanding how societal changes can influence cognitive abilities. His research has deepened our understanding of intelligence development and the factors that contribute to human cognitive progress.
