It seems to me there are two sides to questioning things, you may do so out of curiosity and wonder, which implies an acknowledgement of something unknown and a desire for understanding, or it may disturb you to question beliefs you have held, assumptions you have come to regard as certainties, which often seems to involve fear and denial. I'd like to get a discussion going on this, perhaps there is more to it. Does it fit into any existing psychological theory? C'mon people fire up those neural nets. :)
