IQ is influenced by both genetics and environment (nature and nurture), with studies estimating heritability between 40% and 80%, meaning it is not exclusively one or the other. Genetic influence increases with age—from about 20% in infancy to 60% or more in adulthood—while early environmental factors like education and nutrition heavily shape cognitive development.

Is IQ actually genetic?

Studies have shown that intelligence has a genetic component, but they have not conclusively identified any single genes that have major roles in differences in intelligence. It is likely that intelligence involves many genes that each make only a small contribution to a person's intelligence.

Can two low IQ parents have a high IQ child?

Can you raise your IQ?

Yes, you can increase your IQ score and general cognitive abilities through consistent learning, mental challenges, education, and lifestyle changes, although substantial increases are difficult and often temporary, with the most significant gains seen from education and early interventions rather than just "brain games," which mainly improve test-taking skills. Factors like diet, exercise, sleep, and reading can improve cognitive function, while activities like puzzles, learning new skills, and strategic games can boost specific skills, even if they don't significantly raise your overall IQ number.

Which birth order has the highest IQ?

Does IQ increase with age?

It has been shown that scores on IQ tests actually decrease with age. This chart shows how scores on Wechsler IQ tests peak between 25 and 29 years old, then decline throughout the rest of adulthood, with a decline becoming more steep after the age of 70.
