I have read through a few of the forums which new members asks the older member whether they should start playing basketball because it seems like basketball players are very tall.
The reasoning they probably do is that they see the cause first which they think is playing basketball and then they believe that causes the effect, which is that the players grow taller from it. As the famous quote goes, “one should be intelligence to recognize the difference between correlation and causation”. So the questioner is making a case of causation in this case where it is really a correlation, or even the reverse correlation.
