How do we know what we know about the past?

The human brain works in such a way that we tend to take the information given to us and make inferences based on our prior knowledge. For example, Buzzfeed Unsolved. Although Buzzfeed Unsolved isn’t a historical film, it does cover the basics to prove my statement true for two fundamental reasons. First, the hosts, Ryan Bergara and Shane Madej, interpret information based on inferences made from primary sources. Based on research obtained through reading news stories, finding scientific reports, and interviews to support their topics, the hosts connect ideas to assume what really happened in the past. Though the real cause of the incident may be unsolved, the information provided are real facts. Second, the inferences made are always corroborated. All of the extensive research shown in all the episodes are backed up by either one or two more evidences. For instance, in the case about the strangest disappearances in the Bermuda Triangle, three disappearances are given and within those three disappearances, three to four quotes, recordings, videos, and interviews with professors are presented. Therefore, because inferences are not facts and not all facts presented are true, in order to really know what we know about the past, it is essential to have claims backed up with more than one evidence and then checked against other sources.
