Think about watching a sports match between two teams, where one team is more confident than the other.
The members of the more confident team know that they have a good chance of winning. As a result, everyone on the team makes good decisions, and the players work together seamlessly. Meanwhile, the other team's confidence is shaky. Players doubt their abilities, they hesitate, and they don't commit fully to any particular course of action.
When this happens, it's likely that the more confident team will win.
