Not too sound like too much of an armchair psychologist - I think that mentality comes straight from home, and starts at an early age, when the brain begins to sort out the difference between fiction and fact, what is what.
Me, when I was a toddler, and asked why the sky is blue, my mother would tell me the exact truth to HER best ability "Eh.......... well.... it has to do with... vapor, or something... I have NO idea, maybe it says in the encyclopedia... ?"
With this, I learned a valuable lesson - for life - that authority (my mom at the time) does not have the answers SIMPLY by being an authority. Authority, confidence, loudness, does not equal holding answers. I learned that answers are often hard to find, they require effort, and they may take a long time to explain.
Compare to some parents who actually joke a question away; why is the sky blue? "Because you're stupid! HARDY HAR!" This kills curiousity, and you get these dipshits who never even wonder about what or why or where, clueless for life, and fine with it.
Or the worst culprit - when daddy has ALLLL the answers. ALL of them - with authority and with confidence: "The sky is blue because God made it blue. Now eat your dinner."
