When I think of the words believe and belief, I tend to associate them with prior contemplation and/or experience. With that in mind, I imagine that a person wouldn’t really be stopping to think about their beliefs and assumptions when faced with an emergency like having to lift a car off a child. Because of that, it’s hard for me to grasp the way you’ve explained the above comment.

I open to it, though. How can what you are speaking of be trained?
