Try to keep in mind one of the fundamental aspects of science: letting the evidence form belief rather than belief select evidence. - Greg Craven

My students have described this process of testing ideas in science as: “Hit it with a sledgehammer and see if it breaks. Whatever survives is the best we've got." Science is a very adversarial activity! Hence the old adage among physicists: Physics is a contact sport.

I’ve found that if I can't come up with even an inkling of how my mind might be changed, then I'm not really thinking at all; I'm just set on holding on to my current beliefs.

Knowing how to combat your own confirmation bias helps remove that huge handicap that we all share—the tendency for our beliefs to drift toward what we want to be true.
