Well, let's get back to reality. We were talking about the way normal people think, remember?

So consider a normal person. When, in the course of his typical life, does he have to make choices in a PD situation? At work? When he's drinking beer and watching the game with his buddies or when she's watching a show and gossiping with her girlfriends? When looking for a mate? In relationships with parents or kids?

PD is a neat construct and certainly occurs in real life -- rarely. But for your regular bloke or gal it's a non-issue and they don't spend time thinking in terms of a theoretical situation they don't care about.
