text: When I say that there might be someone with better knowledge about the topic, I mean that someone might have a better thought out and reasonable answer. For example if you ask someone if they think that Football is safe to play. Would you to ask a middle school student who plays Football for their school or a coach of an NFL team? I'm not saying that the middle school football players opinion would not be a good one, I am just saying that an NFL coach would have a more informative opinion than the middle school student. Just because someone has the best knowledge for one question doesn't mean they have the best knowledge for all questions. another example would be if you wanted to know something about middle school Football, then you would ask the middle school student who plays Football and not the NFL coach. All that you need and want is to get the best answer possible for your question.
