“…For example, Lewis Terman’s work in California and the Scottish Mental Survey both illustrated a positive correlation between IQ and longevity ( Deary et al 2008 ; Holahan 2021 ). Wai and Brown ( Wai and Brown 2021 ) using a sample of 48,558 individuals from the US and the UK found that cognitive ability in youth correlated with several positive outcomes in educational, health, social, and occupational attainments. Moreover, the contributions of genetic influences to measured IQ scores appear to increase with age; this may suggest that school-based programming has more influence on younger learners, a view that would support the effectiveness of gifted education and other school-based interventions, or perhaps there are selection effects, motivational differences, or other extraneous variables that influence this relationship.…”
