Did you know these things about heritability?
- Genes, By Themselves, Can't Determine Anything: read how genes are developed through the interaction between genes and environment(s).
- Parents Matter, And Will Always Matter: read how twin studies do not proof at all that parenting and other environmental factors do not impact development.
- Heritability Depends Entirely On Context: read how the heritability of a characteristic is higher in one type of environment than in another environment.
- The Actual Heritability Value Simply Does Not Matter: just because something is heritable doesn't mean it's immutable. Which environmental factors contribute to the development of which characteristics to what extent is still largely unknown.
- Heritability Doesn't Necessarily Have To Do With Biology: Environmental factors influence the development of highly heritable traits just as much as they influence the development of non-heritable traits
- Heritability Says Nothing About Whether Intelligence Is More Determined By Genes Or The Environment: It makes no sense to ask whether a particular individual's intelligence has been more determined by nature or by nurture
- Twin Studies Do Not Reveal The Causes Of Intellectual Development: Because adoption and twin studies are always correlational, they reveal nothing about the causes of the appearance of the traits
- Heritability Is Not The Same As Heredity: Heritability does not tell us how likely it is that people's characteristics will be inherited by their children
