Not everything we believe is true. We may act like it is and it may be uncomfortable to think otherwise, but it’s inevitable that we all hold a substantial number of beliefs that aren’t objectively true. It’s not about opinions or different perspectives. We can pick up false beliefs for the simple reason that we’ve heard them a lot. If I say that the moon is made of cheese, no one reading this is going to believe that, no matter how many times I repeat it. That statement is too ludicrous. But what about something a little more plausible? What if I said that moon rock has the same density as cheddar cheese? And what if I wasn’t the only one saying it? What if you’d also seen a tweet touting this amazing factoid, perhaps also heard it from a friend at some point, and read it in a blog post?
