Why are some people afraid to try foods that they don't like? I can understand not liking a lot of foods (this seems like it isn't a choice, at least) but refusing to taste something that you've never had before?
I went to New Haven with a group of friends to try the famous New Haven apizz'. But one of my friends who's a known picky eater would not even taste the white clam pie. Even though we all made fun of him and tried bullying him into tasting it, he just refused. He also refused to explain himself and just kept saying he didn't want to taste it because it looked bad. Do some people just experience a significant amount of pain when they eat something they don't like? Help me understand this please.
