PPP’s own Steve Kennedy wrote for Slate that, “even before the installation of its conservative supermajority, the court had long viewed scientific evidence that runs contrary to its policy preferences with contempt.”
“Skepticism of an inconvenient scientific consensus is nothing new for the Supreme Court, particularly for the conservatives. In Stanford v. Kentucky, the 1989 case on the constitutionality of capital punishment for 16- and 17-year-olds, Justice William Brennan pointed out the conservative majority’s “evident but misplaced disdain” for scientific evidence, particularly that of the social sciences. In Lockhart v. McCree, Justice William Rehnquist took it upon himself to disregard 14 of 15 submitted peer-reviewed studies, stating that the only reliable study happened to be the one that supported his position, contrary to the scientific consensus. Chief Justice John Roberts has gone so far as to call certain fields “sociological gobbledygook.”
Conservatives’ dislike of science does not stop at social sciences, though. In recent years, conservative justices have made statements completely at odds with the scientific consensus, including saying that carbon dioxide is not a pollutant, and taking the position that a surface connection between navigable waters is necessary for pollution of wetlands to matter. There is a strong scientific consensus contrary to each of these contentions, but the conservative justices chose to disregard it in favor of their prior opinions.”
