Trust is a Continuum. I have relatives who grew up in places where you didn't need to lock the door at night and those who have to lock the door at night but that's enough and those for who that is not enough.

I am reminded of a story I read lately of a woman who was shocked when her passport and purse were stolen from the beach while she was swimming. Somehow she had the perception that she was in a high trust worthy zone even though she had been doing her doctoral thesis work in a low trust society.
