‘Teaching the controversy’ is the best way to defend science, as long as teachers understand the science

The role of science in modern societies is complex. Science-based observations and innovations drive a range of economically important, as well as socially disruptive, technologies. A range of opinion polls indicate that the American public “supports” science, while at the same time rejecting rigorously established scientific conclusions on topics ranging from the safety of genetically modified organisms and the role of vaccines in causing autism to the effects of burning fossil fuels on the global environment [Pew: Views on science and society]. Given that a foundational principle of science is that the natural world can be explained without calling on supernatural actors, it remains surprising that a substantial majority of people report that they believe that supernatural entities are involved in human evolution [as reported by the Gallup organization]; although the theistic percentage has been dropping (a little) of late. This situation highlights the fact that when science intrudes on the personal or the philosophical (within which I include the theological and the ideological), many people are willing to abandon the discipline of science to embrace explanations based on personal beliefs. These include the existence of a supernatural entity that cares for people, at least enough to create them, and that there are easily identifiable reasons why a child develops autism.
