If you could take a drug that would erase only your bad memories and memories of being afraid, would you take it? Metyrapone is a drug that could do just that. While there are some obvious advantages to not remembering certain experiences, the negative side effects could outweigh the positive.
This drug could be a boon to therapists trying to help people deal with trauma. But it's also terrifying when you consider how it could be used to rewrite the way people remember what's happened to them. Instead of mistrusting somebody who hurt you, you'd have nothing but neutral feelings about them. And instead of learning from your painful mistakes, you'd be left in a constant state of ill-informed naiveté.?
