Facts and Evidence Make No Difference – or Worse by Burt Perrin
Hi, I’m Burt Perrin and I’d like you to think about how people really react to evidence. In particular, I will highlight the backfire effect that refers to the reality that when facts are presented that show that one’s cherished beliefs are wrong, instead of people changing these (incorrect) beliefs, they become even stronger. This has profound implications for evaluation, with the predominant view still that the role of evaluation is to produce evidence.
