“What’s true? What’s false? In case you haven’t noticed, the world has pretty much given up on the old Enlightenment idea of piecing together the truth based on observed data. Reality is too complicated and scary for that. Instead, it’s way easier to ignore all data that doesn’t fit your preconceptions and believe all data that does. I believe what I believe, and you believe what you believe, and we’ll agree to disagree. It’s liberal tolerance meets dark ages denialism. It’s very hip right now.”
