On Favorite Teams

Scott Adams has a theory:

If you wear the jersey of your favorite team, your brain associates the colors and the logo with the good feelings of watching a game. The rational part of your brain might tell you that you wear the team jersey because you look good in those colors, or you support the team. But I think the real reason is a simple association with the stimulation you feel when watching your team compete. It's an accidental subroutine.
