> Isn't that a little bit like saying that you shouldn't change your views after reading a book, if you are aware that the book commonly changes views? No, it's closer to changing your belief from "chocolate is bad for you" to "chocolate is good for you" after having a particularly good-tasting piece of chocolate. Unlike reading a book on the health benefits of chocolate, your change in belief does not logically follow from your experiences, at least not in an obvious way. Since drugs aren't going to alter your priors, it seems as though the change in belief is purely emotionally driven. Which is odd.
