This case should be decided on the basis of the law, without reliance on the social science studies and authorities that Respondents and their amici will undoubtedly put before the Court. The social and behavioral sciences have a long history of being shaped and driven by politics and ideology. This is partly because researchers often choose to study issues implicating controversial questions of public policy. And it is partly because it is often impossible to perform the kind of objective observations and controlled experiments that are standard in the physical sciences. History is littered with notorious examples of false theories gaining wide acceptance among respected social and behavioral scientists, some of which supported pernicious public policies.
