Misinformation can be harmful. What are we going to do about it?

What is misinformation?

Bad information. You know, the sort of information coming intentionally or accidentally from friends or enemies that might harm us in some way. It can harm us in some very small way, like following directions to go left when we really need to go right. It might be life-changing. It might be deadly, like being told that we can smoke cigarettes and not fear the threat of lung cancer. Misinformation is harmful information because it is false.
