Examples, anecdotes, single cases, and testimonials are all potentially deceptive. According to numerous testimonials, believers in the power of the “secret” described above have been showered with money, success, and happiness immediately after viewing the video. Unfortunately, such individual cases (or even several) tell us nothing about what is true in general (Stanovich, 2010). How many people didn’t win the lottery after buying the video? How many people bought the “magic necklace” to no avail? Similarly, studies of large groups of people show that smoking increases the likelihood of lung cancer. It is less relevant if you know a lifelong heavy smoker who is 95 years old. The general finding is the one to remember.
