Why is it so tempting to pick at scabs?

Is it the "reverse psychology" of that we know we should't do it, or is it something completely different?

Actually, not everyone does this. It's a compulsive behavior and, like other compulsions, we still don't know exactly why people do it. There is some evidence that it releases endorphins though.

Also, wanting to do something that you shouldn't is not reverse psychology. The term refers to making an argument contrary to the one that you actually want to make so that the other person, in arguing against you, actually makes your point for you. The goal is to have them convince themselves of your point so that they feel like the advice came from within instead of being forced upon them by an external force.
