Editing Gambler's fallacy (section)

==== Baseball umpires ====
In the game of [[baseball]], decisions are made every minute. One particular decision made by [[Umpire (baseball)|umpires]] which is often subject to scrutiny is the 'strike zone' decision. Whenever a batter does not swing, the umpire must decide if the ball was within a fair region for the batter, known as the [[strike zone]]. If outside of this zone, the ball does not count towards outing the batter. In a study of over 12,000 games, results showed that umpires are 1.3% less likely to call a strike if the previous two balls were also strikes.<ref name=":0" />
