The Flynn Effect is the phenomenon in which there is a marked increase in intelligence test score averages over time. They found that the increase of scores of general intelligence stopped after the mid-1990s and declined in numerical reasoning sub-tests.

We have eradicated some major infectious diseases, allowing for better quality of life and more intellectual pursuits. From pictures on the wall to movies to television to video games to computers, each successive generation has been exposed to richer optical displays than the one before and may have become more adept at visual analysis. A Norwegian study found that height gains were strongly correlated with intelligence gains until the cessation of height gains in military conscript cohorts towards the end of the 1980s. One problem with this explanation is that if in the US comparing older and more recent subjects with similar educational levels, then the IQ gains appear almost undiminished in each such group considered individually. Let's examine a few ways that researchers have operationally defined intelligence. The Flynn effect tells us that the human mind is much more adaptable and malleable than we might have thought. For example, a study published in the year 2009 found that British children's average scores on the Raven's Progressive Matrices test rose by 14 IQ points from 1942 to 2008. Substantial portions of IQ tests deal with these abilities. 3 Center for Neuro-Engineering and Cognitive Science, Department of Psychology, University of Houston.
