Flynn effect

The Flynn Effect is a name for the observation that people's intelligence test scores have been gradually increasing over time. This means that if you take an IQ test today, your score is likely to be higher than it would have been if you had taken the same test a few decades ago. The effect is named after James Flynn, an American scientist who noticed this pattern in the 1980s. The precise reasons for the Flynn Effect are not well understood, but some experts believe that as society gets more educated and people have access to more information, they become better at solving problems and understanding complex concepts, which makes them score higher on IQ tests.
