intelligence

Your baseline for intelligence has shifted over the decades.

The Flynn effect describes the observed rise in raw IQ scores throughout the 20th century.

Between 1930 and 1990, raw test scores increased significantly across various countries. This was not due to a sudden jump in innate intelligence, but to changes in how we navigate abstract logic, education, and nutrition compared to previous generations.

Environment shapes the cognitive tools you use to think.
