Scientists find reason behind split-second sporting disputes

Players automatically perceive their own actions ahead of rivals, research shows

Whether it's rushing to push the buzzer on a quiz show or working out who last touched a basketball before it left the court, players often end up squabbling over moments that turn on milliseconds. But now scientists say there is more to the disputes than sour grapes or angling for an advantage.

Researchers have found that when two players press a button simultaneously, they both judge their own action as having taken place about 50 milliseconds before that of their opponent.
