People believe in many different superstitions and engage in all kinds of superstitious behaviors. Baseball players and coaches are notoriously superstitious. When the Detroit Tigers went on a winning streak in the summer of 2011, Tigers’ manager Jim Leyland refused to change his underwear, wearing them to the park every day until the winning streak ended. Skinner thought superstitions resulted from the unintended reinforcement of inconsequential behavior.
