Choice overload . . . makes people worry about later regretting the choice they make (If there are twelve things I could do tonight, any one of them might end up being more fun than the one I choose); sets them up for higher expectations (If I choose this party out of those twelve things, it had damn well better be fun); makes them think about the road not taken (Every party not attended could contain someone I wish Id met); and leads to self-blame if the outcome is bad.
