What does the Flynn Effect refer to?

The Flynn Effect refers to the observed phenomenon of rising IQ scores over time across generations. This trend was first identified by psychologist James Flynn, who analyzed various IQ tests and noticed that scores have increased significantly throughout the 20th century and into the 21st century. The reasons behind this increase are thought to be complex and may involve factors such as improved nutrition, increased access to education, better healthcare, and more stimulating environments, including exposure to technology and media. This increase indicates that intelligence, as measured by these standardized tests, can be influenced by environmental factors rather than being strictly determined by genetics.
