The Flynn Effect refers to the observed rise in average IQ scores over time across many populations. Named after psychologist James R. Flynn, this phenomenon suggests that each generation scores higher on intelligence tests than the previous one. This increase has been documented in various countries and is thought to be influenced by factors such as improved education, better nutrition, and more complex environments. Researchers have noted that the Flynn Effect is not uniform; it varies by region and demographic groups. While the reasons behind this trend are still debated, it highlights the importance of considering environmental and societal changes when assessing intelligence over time.
