The Flynn effect shows that each generation tends to have a higher IQ than the last generation.
What is meant by the Flynn effect?
The rise in standardized intelligence test scores over time known as the "Flynn effect" was noted by Flynn (1984a) in research on increases in IQ scores in the standardization samples of succeeding Stanford-Binet and Wechsler intelligence tests.
Why does the Flynn effect happen?
The Flynn effect idea proposes that advances in nutrition and education are partially responsible for the rise in IQ scores. Along with this, more people are reading, and modern technology like computers and the internet makes people think in more abstract ways. The result of everything is an improvement in IQ score.
What are the 3 possible causes of the Flynn effect?
In his initial proposal, Flynn divided potential explanations into three categories: artifacts (such as sample errors or advancements in early childhood education), test sophistication, and actual increases in intelligence. In order to demonstrate the intricacy of the Flynn Effect, Deary (2001) addresses the flaws in the explanations that have been proposed.
