IQ test results strongly predict income, education, health, and longevity, though weaker for individuals (similarity 0.91)
Education strongly predicts adult cognitive test scores in both directions (similarity 0.82)
The generational rise in IQ scores is attributed to environmental factors like improved nutrition, education, and reduced toxin exposure. (similarity 0.81)
With heritability well below 1.00, IQ must be subject to substantial environmental influences, though genetic influence increases with age while shared family environment effects shrink by late adolescence. (similarity 0.80)
IQ has risen across generations worldwide, and the effect must be environmental since genetic mutation could not act that fast, amounting to about 15 IQ points per generation on fluid tests. (similarity 0.80)
