Placebo Effect applies

The placebo effect involves the idea of “mind over matter”, and in the situation of a sports team playing in their home city, the placebo effect applies mostly because of support from the surrounding crowd. The crowd supports the home team, and in turn, the players’ mentalities grow confident with the support. Because the crowd cheers for the local team so much, the players believe they are doing well, and it influences their overall performance. Players doing well in their local city may also have to do with their familiarity to the area. Depending on the individual, the person may gain a larger sense of confidence because of that familiarity.
