We had a previous discussion on this topic, but it is a problem that is becoming increasingly acute in light of some recent political discussions.
Both "sides" of the political scale tend to have certain areas in which they seem to have an unorthodox view of science and how we acquire and use knowledge. The right often objects to explanations using evolution and claims of global climate change; the left often strays into mystical, new-age thinking and evangelical veganism, and, into a "blank slate" view of human nature. While these are grossly over-simplified statements, they seem to provide a starting point for a discussion that might lead to ways to avoid politicizing scientific and intellectual thinking.
Several of us walk across the parking lot after the discussion to have something to eat at El Arroyo on Wood Hollow.
