Practicing these skills through formal schooling can lead to higher test scores.Growth mindset : When students are taught that their intelligence is malleable and can grow, rather than fixed, they become more motivated to learn and take on challenges. Studies have shown that this shift in mindset can result in cognitive gains.Societal effect : Increases in average IQ scores worldwide over the past century, a trend known as the "Flynn effect," have been partially attributed to widespread improvements in education, nutrition, and environmental complexity.Mechanism : A 2018 meta-analysis combining 28 studies found that an additional year of schooling is associated with a gain of 1 to 5 IQ points, with effects lasting into old age. The analysis employed different study designs to account for the possibility that smarter people simply seek more education. These included:Educational policy changes : Research examining reforms that increased the minimum compulsory schooling age found corresponding increases in IQ scores for the affected cohorts.Natural experiments : Some studies compare students with similar backgrounds who received slightly different amounts of schooling due to age-based admission cutoffs.Early childhood intervention : High-quality early childhood education has been shown to produce significant gains in intelligence, particularly for children from disadvantaged backgrounds, with some studies showing the effects persist for years. However, the long-term persistence of IQ gains from some intensive early programs is debated.
