Home-field advantage is no myth. According to Tobias J. Moskowitz and L. Jon Wertheim, in their book “Scorecasting,” the home team wins more often than the visiting team. Why? The writers state: “Officials’ bias is the most significant contribution to home-field advantage.” The officials respond to the pressure from the fans because they don’t like to get booed. When the contests are close, the officials tend to make calls that favor the home team.
