Arguing that common genetic variants explain much of the variation in general intelligence, they suggested that the effects of individual variants are so small that very large samples are required to reliably detect them. [78] Genetic diversity within individuals is heavily correlated with IQ. [79]
Intelligence quotient (IQ) tests do correlate with one another and that the view that the general intelligence factor (g) is a statistical artifact is a minority one. IQ scores are fairly stable during development in the sense that while a child's reasoning ability increases, the child's relative ranking in comparison to that of other ...
Environment and intelligence research investigates the impact of environment on ... Even if there was enough genetic material to code neural connections, it is ...
Hereditarianism is the research program according to which heredity plays a central role in determining human nature and character traits, such as intelligence and personality. Hereditarians believe in the power of genetic influences to explain human behavior and solve human social-political problems.
The degree to which intelligence test scores can be linked to genetic heritability increases with age. There is presently no explanation for this puzzling result, but flaws in the testing methods are suspected. A study of Dutch twins concludes that intelligence of 5 year olds is 26% heritable, while the test scores of 12-year-olds is 64% heritable.
Genetic research on human behaviour has long been linked with eugenics and continues to attract interest from far-right groups. Blueprint by Robert Plomin: latest intelligence genetics book could ...
In 2018, in response to a resurgence of public controversy over race and intelligence, the geneticist and neuroscientist Kevin Mitchell made a statement in The Guardian that described the idea of genetic IQ differences between races as "inherently and deeply implausible" because it goes against basic principles of population genetics. There he ...
