"As humans, we reflexively reject arguments that contradict what we would like to be true."

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

“Scientists are trained to not give absolute answers. It is interesting that in recent years, some have started to do so when talking with the media, because they've learned that whenever they include the very scientific words possibly, perhaps, and uncertainty, their conclusions are interpreted by the media and public as simple guesswork.”

“The clever part is that it changes the question from, Who should I believe? to, What should I do? After all, the physical world is unaffected by our beliefs. It reacts only to our actions.”

“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.”

“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.”

“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.”
