There is a common misconception that genes are deterministic and that human potential is fixed at birth. This could not be further from the truth. We, as behavioural geneticists, see no evidence whatsoever for genetic determinism in how, what and why children learn.
In the recent debate about genetics and education, and whether those two words even belong in the same sentence, the influence of a child’s “non-shared environment” has largely been overlooked.
To elaborate, if you cloned one child 30 times and sent them into the same class at the same school with the same teacher, the chances are you would see 30 outcomes, all at least slightly different from each other.
We see this in cloned animal litters and in identical twins. The question that behavioural geneticists ask is why. How it is possible for genetically identical organisms to develop differently? And we try to find an answer by looking at experiences which differ between identical twins.
