Another well-known distinction between sports fans classifies them as “true fans” vs. “fickle fans.” The Vallerand et al. model sets that aside in favor of the two types of passion in fans. You can be a harmoniously passionate fan who is happy when the team wins and sad when they lose but still enjoy the actual game itself. If you’re an obsessive fan, you’ll make the team’s performance a central part of your entire existence, and therefore need the team to win to feel happy and fulfilled. Obsessive passion is, therefore, a less adaptive stance because your team can never win 100% of the time. Across a series of 3 studies of European football fans, the Canadian researchers examined the contributions of the two types of passion to various outcomes. Obsessive fans were more likely to experience maladaptive emotions such as hate for the opposing team, and they also mocked fans of opposing teams. Harmonious fans were more likely to have high levels of self-esteem and life satisfaction, and more likely to show their feelings in positive fan behaviors, such as celebrating their team’s victories in the streets. Not surprisingly, obsessive fans had poorer relationships with their partners than did harmonious fans, as you might imagine if you’ve seen couples where one partner ignores the other's needs in favor of sports.
