The reasons for the population-level increases in intelligence test scores over time are unclear but may reflect the increased reliance on certain skills like abstract thinking and logical analysis. It is not necessarily the case that children today are actually smarter than their parents were, as intelligence is a complex and multifaceted construct that cannot be reduced to test scores alone. Furthermore, the increase is unlikely to be solely due to people being better test takers, as the Flynn effect (i.e., the term used to describe the increase in intelligence test scores over time) has been observed across a variety of different types of tests and for different age groups. While lower levels of stress experienced by today's youth compared to the youth of the 1930-1950's may be a contributing factor, it is not the most likely explanation for the Flynn effect.
