Whenever we set out to learn something new, or we run across information that seems new to us, what makes us trust the information as being truthful? When it comes to matters that are testable through the scientific process, how can we be sure that the explanation being offered, is the best one? When we feel that someone is telling us the truth, is it because of confirmation biases that lead us to believing those truths? The best explanation should be a factual and reasonable one, but how do we trust facts and reason? Is it because the facts are accepted by the majority? How can we evaluate and trust reason to ensure that it serves us as the ''best'' explanation? What are your ideas on this?
