This graph summarizes the data, with “average Americans” in tan, football fans in maroon, and other fans in olive. Now since the survey methodology reports a survey of 1,011 adults—not just sports fans—I assume that the data below represent a subset of those Americans who follow sports. But, according to the data, that is 89% of all Americans (I’m one of the other 11%).

Yes, exactly half of the fans (and 55% of football fans) see supernatural influences in sports.
