Correlation Does Not Imply Causation
quote
You may have heard anecdotes about people who happened to get cold and flu symptoms around the time that they got the flu vaccine and blame their illness on the vaccine. Just because two events happened in succession, or are correlated, doesn't mean that the first actually caused the second. Statisticians use the phrase correlation does not imply causation to describe this fallacy.
