Jonah Lehrer revisits the "tendency of many exciting scientific results to fade over time":
One of the sad ironies of scientific denialism is that we tend to be skeptical of precisely the wrong kind of scientific claims. Natural selection and climate change have been verified in thousands of different ways by thousands of different scientists working in many different fields. (This doesn’t mean, of course, that such theories won’t change or get modifiedthe strength of science is that nothing is settled.) Instead of wasting public debate on solid theories, I wish we’d spend more time considering the value of second-generation antipsychotics or the verity of the latest gene-association study.
