Who needs the careful application of the scientific method when congressmen with absolutely no scientific training are making decisions?
The conservative attack on science is old and driven by many factors: religious opposition to reason, Barry Goldwater-style anti-intellectualism, corporate muscle, and straight-up Nixonian lies. Nixon liked to play the role of philosopher king, privately conceding that the Vietnam War was unwinnable but declaring the American people unworthy of knowing so. There are some who resist science because of sincere if misguided religious belief, and others who consciously manipulate facts for economic gain. The result, however, is always the same: a stupider America less well-prepared to make good decisions.
