And that's part of the problem - you're thinking of it like a hammer when it's not a hammer. It's asking someone at a bar a question. You'll often get an answer - but even if they respond confidently that doesn't make it correct. The problem is people assuming things are fact because "someone at a bar told them." That's not much better than, "it must be true I saw it on TV".
It's a different type of tool - a person has to treat it that way.
