Nope: there is also no law or force that magically pulls things back towards the mean. Regression to the mean is merely a tautology: If the numbers don’t move back towards the mean, the mean moves to keep with the numbers!
When Babe Ruth hit 29 home runs in 1919, that was more than double what anyone had hit before in a season. Do you think the next year a magical force called “regression to the mean“ pulled his numbers back to the previous mean?
And by the way, sports writers get this completely wrong all the time, and use “regression to the mean“ as if it was some magical force influencing actual performance
Very well said.
And by the way--for you gamblers--this myth about some kind of "regression to the mean" correcting force is one of the concepts that the sports books use to take your money. They know it doesn't exist, but half-smart second-half bettors will keep playing it until they are broke.
