Examples of regression toward the mean can be found in every aspect of life. If a basketball player scores 50 points in a game, a personal best, it is highly likely that he will score fewer points the next game. And similarly, if he scores three points, his worst game in two years, it is almost certain that he will do better the next game. Children of seven-foot-tall basketball players are tall—but not usually as tall as that. And so forth.
