What does the Flynn Effect refer to?

The Flynn Effect refers to the observed phenomenon of rising IQ levels in industrialized nations over the past several decades, particularly since World War II. This increase suggests that average IQ scores have been steadily improving across generations, indicating that environmental factors such as better nutrition, education, and more stimulating environments play a significant role in cognitive development.

This ongoing trend highlights the impact of societal changes on intelligence testing and emphasizes the adaptability of human cognitive abilities over time, rather than implying that intelligence is solely fixed or genetically determined. The details surrounding the Flynn Effect offer valuable insights into how various factors can influence intelligence and point to the importance of considering context when assessing cognitive abilities.
