But there are an enormous number of policy questions that must be informed by the latest science—energy policy, space exploration, funding for medical and basic science research, just to name a few. The goal of any science debate would be to explore just how well the candidates understand the underlying scientific facts behind these issues. With scientific literacy at its current (depressing) level in the U.S., there's no reason to believe that our would-be leaders have a thorough understanding of the science that must go into making intelligent policy decisions. More important, even if they do possess the understanding, a science debate would force them to articulate how that knowledge would affect their actions as president. Do you understand the science? Does the science matter? That's what I'd like to know from each candidate before I vote.
