Hubris is the enemy of skepticism because skepticism begins with recognizing how our thinking can go awry, not just Ben Carson or other cranks but you, me, everybody. Critical to that recognition is having the humility to recognize that we all believe things without evidence and to begin to test our most deeply held beliefs against reality in order to determine which ones are supported by evidence and which ones aren’t, testing that must involve seeking out disconfirming evidence. Most importantly, we must have the humility to be able to admit when we are mistaken and be willing to change our minds when the evidence does not support our beliefs.
