I've written before about the value and importance of evidence-based thinking. A friend just sent me a link to a rather shocking article by Gary Baum writing in the Hollywood Reporter about rapidly declining vaccination rates in the elite schools of the Westside in Los Angeles (where I live). In popular talks I note that non-scientific thinking is not a 'red' or 'blue' issue--it's rampant and I use the example of low vaccination rates in the Westside. Baum's article is a wake-up call for science-based policy and decision making. Read and discuss it at your next party!
