I saw the logic that they used, and the death of a thousand cuts as experimental scientists slowly chipped away at the belief that the world was an inexplicably powerful, magical place.

I'm of the old-fashioned opinion that shame can be used for all sorts of good in society. An example of this is smoking: When someone lights up around a crowd, people now usually say something. So I don't understand why it's not OK to apply the same logic to other behaviors.
