Sources

There are many different sources we can find for a research paper, article, or maybe even a movie with non-fiction element. However, it is difficult to know which one is good or trustworthy. Usually a primary source is more trustworthy than a secondary source because it comes from a person that lived through the experience and witness the event. That is first-hand source and it's the best source unless the person is not reliable. A primary source means that the source comes directly from the person that experienced the event to the receiver of the information. For example, if someone lived through the extinction of dinosaurs and they write it in their journal. That would be a primary source because it is from the person that lived the experience directly to the receiver of the information. A secondary source would be a person gathering one or more information from the people that lived through the experience, compressed and distribute to the receiver. This is very dangerous because often what happens to secondary source is that the writer that gathers the information include their own thought and making the information, otherwise neutral, bias. This can be bad when we want a very neutral source and we just want the original information. It's okay if the primary source is bias because it tells the receiver the experiencer's state of mind during the event, but if the secondary source is bias, it is really bad.
