A lot of what we believe to be true is based on trust rather than in-depth understanding and verification. This is not a failing of people. Even the most educated person can only have so much understanding. We must use proxies such as credibility to determine who to trust. This reminds me of the time that I discover a discrepancy of facts about when variolation was discovered. One source said 11th century, and the other is 15th century. Which is true? Unfortunately, I wasn't able to ascertain the truth of the matter, for I am not a historian and don't possess infinite time for fact verifications. I was only able to do the most superficial of fact checking, seeing if the sources agree with each other and that was time consuming enough.
