OK, I changed my mind (three times!)

by Massimo Pigliucci
As regular readers of this column know, I occasionally try to debunk the myth that skeptics are just a bunch of curmudgeons and naysayers, people who have a strong psychological need to feel superior and always right. As a small contribution to this demystification, let me tell you about not one, not two, but three (!!) instances in which I changed my mind about issues of concern to freethinkers and skeptics, and in the process try to learn when it is in fact reasonable to change opinion.
