The easiest, but not necessarily the most applicable answer, is that it is possible to wager money on the outcome of sports games. Very large sums of money. Ruinous, life-altering sums.

The more common answer is that this is a sense of personality for some people. They identify with a certain sports team and spend a lot of their time cheering them on and building up the belief that they are the best team, undefeatable under any fair circumstance. When that team loses, they then take it personally. After all, if their team lost, could it mean they’re not actually the best team? Did I choose wrong?

No. Impossible. It’s those damn referees, blind as they are, missing the most obvious fouls and treating my team unfairly, punishing my team’s players more harshly for the tiniest infractions. Nay, not even that; my team didn’t break the rules; it’s that other team’s fault!

&c., &c., until you get bored.

It isn’t reasoning driving these decisions. It’s emotion. And before any of us get too haughty about it, it’s also a very human reaction. Humans were not designed to reason, we were designed to feel. And yes, everyone has a set of circumstances that will cause their logical processing to shut off and allow emotion to take control. It just might not be sports.
