In this video, Paul Henne (Duke University) explains the post-hoc-ergo-propter-hoc fallacy. This is an informal fallacy committed when a person reasons that because one event happened after another event, the first event caused the second. He also discusses why it is sometimes hasty to conclude that your cat scratch caused your fever.
