There's a great idea floating around science blogs: bring back the White House Office of Technology Assessment:
It used to be, for about 20 years (from 1974 to 1995), there was an office on the Hill, named the Office of Technology Assessment, which worked for the legislative branch and provided non-partisan scientific reports relevant to policy discussions. It was a critical office, one that through thorough and complete analysis of the scientific literature gave politicians common facts from which to decide policy debates. In 1994, with the new Republican congress, the office was eliminated for the sake of budget cuts, but the cost in terms of damage to the quality of scientific debate on policy has been incalculable. Chris Mooney described it as Congress engaging in "a stunning act of self-lobotomy" in his book the Republican War on Science (RWOS at Amazon).
The fact of the matter is that our government is currently operating without any real scientific analysis of policy. Any member can introduce whatever set of facts they want, by employing some crank think tank to cherry-pick the scientific literature to suit any ideological agenda. This is truly should be a non-partisan issue. Everybody should want the government to be operating from one set of facts, ideally facts investigated by an independent body within the congress that is fiercely non-partisan, to set the bounds of legitimate debate. Everybody should want policy and policy debates to be based upon sound scientific ground. Everybody should want evidence-based government.
Seems like a good way to help ensure that policies are made using the best available science (plus it will create a few good science jobs!)
