We all like to think we keep an open mind and can change our opinions in the light of new evidence, but most of us seem to be geared to making up our minds very quickly. Then we process further evidence not with an open mind but with a filter, only acknowledging the evidence that backs up our original impression. It is too easy for us to fall into the rap of believing that being right is more important than being open to what might be. - Philippa Perry from “How to Stay Sane”
