The Will Rogers phenomenon is obtained when moving an element from one set to another set raises the average values of both sets. It is based on the following quote, attributed (perhaps incorrectly) to comedian Will Rogers:
- When the Okies left Oklahoma and moved to California, they raised the average intelligence level in both states.
The effect will occur when both of these conditions are met:
- The element being moved is below average for its current set. Removing it will, by definition, raise the average of the remaining elements.
- The element being moved is above the current average of the set it is entering. Adding it to the new set will, by definition, raise the average.

“The expectation that every neurotic phenomenon can be cured may, I suspect, be derived from the layman’s belief that the neuroses are something quite unnecessary which have no right whatever to exist. Whereas in fact they are severe, constitutionally fixed illnesses, which rarely restrict themselves to only a few attacks but persist as a rule over long periods throughout life.”
—Sigmund Freud (1856–1939)
