In the Jan. 12 issue of ESPN the Magazine, Peter Keating breaks down a number of different reasons why teams enjoy an advantage at home. The entire article is worth a read (though you’ll have to buy a copy since the article isn’t available online), but the part that jumped out at me was a study that was done on soccer officials back in 2007.
In every major pro sport over the past five years, home teams have benefited from a differential in calls made by the officials. Before you send irate e-mails to David Stern or Roger Goodell about zebras on the take, know this: Researchers say it’s likely that officials are subconsciously channeling fans’ preferences. “Referees get a lot of abuse, and as far as crowds are concerned, the only good decisions they make are those that help the home team,” says Paul Ward, a cognitive psychologist at Florida State. “If you’re looking for a way to deal with the stress of quick decisionmaking, favoring the home team is a way to reduce anxiety”
To test this hypothesis, Ward and his colleagues strapped a group of soccer refs, coaches and players to EKGs and asked them to call videotaped games. Half watched games with crowd noise, the other half without. The results, published in 2007, showed that the participants subjected to crowd noise reported more mental anxiety–and called 21% fewer fouls on the home team.
Bingo! This is why the intensity of crowds generates an advantage for home athletes. More fan frenzy equals more ref anxiety.
It makes sense that if an official is calling a game in front of a packed house of 20,000 screaming fans, that it’s not unlikely that the ref will eventually bend to the fans’ will. They may have every good intention of calling the game right down the line, but it’s human nature to try to reduce your own stress, and the easiest way to do that is to make the people around you happy.
So if you’re ever at a game and wondering if it’s worth the effort to stand up and cheer (or boo your fool head off), now you have your answer.
