What makes someone curious?

Why do some people question information and others just take it in, believe it as fact and go on about their business?

If we only know what was spoonfed and expected of us, what do we really know? What are we getting out of this belief? Are we willing to ask questions and admit we don’t know everything? Why is what we perceive to know, enough? What research have we done to support our hypothesis that what we choose to believe is right? Why do we stop questioning?

How many times do you silence the little voice inside of you that tells you something is wrong until you don’t hear it anymore?
