Sure, we may stumble a little, asking ourselves "Why does somebody in the Dallas plant need to see the new product plans?" or "Could it hurt anything to give out the name of the server it's on?" So we ask another question or two. If the answers appear reasonable and the person's manner is reassuring, we let down our guard, return to our natural inclination to trust our fellow man or woman, and do (within reason) whatever it is we're being asked to do.
