What phenomenon describes the overall rise in intelligence test scores over the past century across various demographics?

• A. Spectator Effect
• B. Flynn Effect
• C. Hawthorne Effect
• D. Self-fulfilling Prophecy

Answer: (B)

The phenomenon that describes the overall rise in intelligence test scores over the past century across various demographics is known as the Flynn Effect. This term is named after researcher James R. Flynn, who observed that average IQ scores have been steadily increasing over time in many parts of the world. The Flynn Effect has been documented across different countries and demographic groups, indicating that this trend is not limited to a specific population. Several factors are believed to contribute to this increase, including improvements in education, better nutrition, and more complex environments that stimulate cognitive development. The phenomenon highlights the influences of socio-economic and cultural factors on intelligence testing, suggesting that intelligence is malleable rather than purely determined by genetics. Understanding the Flynn Effect helps researchers and educators consider how test scores can reflect not just individual ability but broader societal changes over time.
