text: By asking more then one person you are almost always going to find people of varying knowledge, and by getting people with higher knowledge you have a much lower chance of being misinformed or having to deal with bias. Now as you read that last sentence you probably thought yes of course being misinformed will happen less but bias would still be there yes? No, If the person you ask has more knowledge then why would they change there awnser to fit some political quota that they have instead of just telling you the awnser, If what they know is right why would they tell you something that they know is not right on purpose. By asking lots of people you will be able to like Danny said "Sift through the duds." you will eventually find someone who lacks bias and who has enough knowledge on the subject to help you. Also once you find that special somebody who know about this subject they will probably know about similar subjects, a example of this would be my friend Generic_Name, Generic_Name knows a lot about geography and history as well as some biblical history, so whenever I have a question about Geography, history, or a story in the bible I will just ask him about it. He is a trusted source that I have and by finding him I have basically found a book about history and geography that I can read anytime I need to read it, and something my Generic_Name book does that normal books don't is that he gains knowledge. The more I wait in between asking question the more he will know about something.
