The Impact of Crowd Noise on Referee Decisions

Crowd noise significantly influences referee decisions during football matches, as demonstrated by a study where referees awarded fewer fouls against home teams when crowd noise was present. Researchers divided referees into two groups; one watched a match with crowd noise, while the other did so with the sound muted. The findings revealed that those who heard the noise were 15% less likely to penalize the home team for fouls. This highlights how cognitive biases, influenced by the crowd, can alter perceptions and decisions in high-pressure situations.
