While approaches to child development that emphasize nature over nurture may appear to be more grounded in science than in behavior modification, both nature and nurture have scientific foundations that are paired with environmental controls.

In terms of Nature vs. Nurture, how much of people's behavior is the result of genetics (nature), and how much is the result of the physical and social environment (nurture)? But this is a hard claim to test unless environmental differences are large often enough, and unless various other statistical conditions are met.

Strictly speaking, a single well-authenticated case of identical twins reared apart between whom a dramatic difference appears should be enough to invalidate the hypothesis that ''heredity is destiny.'' He then gave the test records, with all identifying information removed, to another psychologist, who correctly matched only two sets of twins. It only implies that the evidence we have for saying nature is now stronger. "Nature vs. Nurture." (May 2013). This article is not about a study, but rather it gives a more personal account of a set of twins separated at birth and raised in very different .

She simply points out that the other studies were conducted at a time when the easiest way to collect data on identical twins reared apart was to advertise widely (as James Shields did on television for his British study), asking people to come forward.

The hereditarians' claim is, rather, that although both heredity and environment play a role in shaping development, differences in heredity are far more important than differences in environment. Dr. Farber says in her chapter on psychosis, ''The best-separated set in the literature ... still is so poorly separated that the original paper speaks specifically to the issue of whether the twins' knowledge of each other, which they interwove in their delusional systems, was significant in the onset, course, and content of their paranoid states.'' Shafran, Gallan and Kellman weren’t the only adoptive babies included in the study, with many others likely completely ignorant of the fact that they have identical siblings. Twin and adoption studies are two instances of a much broader class of methods for observing nature-nurture called quantitative genetics, the scientific discipline in which similarities among individuals are analyzed based on how biologically related they are.
