i've always believed that mood affects outcome. specifically that a positive mood is more likely to yield a positive outcome than is a negative mood (within the realm of that which can be influenced by you). flipping a coin happily is unlikely to yield a greater occurrence of the chosen side than flipping that same coin angrily; the same, i believe, cannot be said of shooting free throws. in a positive mood, challenges present opportunities; in a negative mood, obstacles. as a fan, you have the ability to influence the game. it is a small influence, indeed, but it is still a potential influence. either by booing or by cheering, fans can alter the atmosphere of a game, turning it into either a positive or a negative. that characteristic of the atmosphere can influence the way the players play the game, as is alluded to often enough. players pressing, or playing loosely. trying too hard, or going with the flow. i believe that this atmosphere can affect the outcome of plays in subtle ways. take, for instance, a ground ball to the shortstop. if the crowd has been unrelenting and unforgiving of a lack of performance by the home team, the batter may think 'fuck, i'm going to get thrown out, and they're gonna grill me' and, presupposing the outcome to be negative, perhaps the player doesn't hustle, or slows up as the play is made. if the crowd has been encouraging and supportive, the player may think 'maybe he'll boot it. maybe i can get him to rush and throw it away' and the player runs ever so slightly harder to first, perhaps fulfilling that prophecy. the player reactions, despite their being 'professionals' and paid to play a game' are all natural human responses to the environment. positive environments bringing about a greater likelihood of positive responses to the environment, and a greater likelihood of turning challenges into opportunities which are increasingly taken advantage of, as opposed to negative environments brining about greater likelihood of negative responses to the environment, and a greater likelihood of turning challenges into obstacles which are increasingly stumbled over. given all that philosophical mumbo jumbo, booing the home team is dumb, as it is unlikely to make the team perform better, and is more likely to make the team perform worse. i want my team seeing opportunities, not obstacles. won't you please help them? feel free to boo from home, though. i'm not nuts enough to think that the negative energy you create in your tv room, basement, or the local bar, is going to have any impact on the game - you can't influence it if you're not there.
