Sanctioned fighting has played an integral role in the National Hockey League (NHL) since its early days. Proponents argue that this practice helps teams win games. More specifically, they contend that when a player triumphs decisively in a fight, the outcome creates momentum or a spark for his teammates and thus increases his team’s odds of victory. We used on-line fans’ voting (validated by objective fight data) to assess fight outcome and demonstrated that “winning” the fight did not lead to winning the game when the score was tied. Additionally, in contrast with the “change in momentum” hypothesis, prevailing in a fight did not sway game outcome when the home or away team was one goal behind early enough in the game. Lastly, prevailing in a fight was not associated with scoring the next goal. We discuss the results in light of the strong conviction held by NHL players that fighting boosts momentum and explain possible mechanisms working to preserve this false belief. |
