"Curtain of Distraction"
Home court (and home field) advantage may be one of the most documented and replicated phenomena in the field of psychology. It shows up in every major sporting competition: soccer, football (professional and collegiate), baseball, college basketball, and the NBA. There is a wealth of statistics supporting its existence, literally spanning three centuries.
Since 2010, home teams in the NBA have won 59% of their games, with an average point differential of 2.8 points. While home court advantage has been on the decline, relative to the veritable coach and buggy days of the 1970's (see this chart from ESPN's Tom Haberstroh), rumors of its eventual demise may have been exaggerated.
At this point in the season last year, home teams had an all-time low winning percentage of just 53.7%. It appeared we were in the midst of a home court advantage sea change. NBA teams were finally winning the road battle, thanks to advanced biometrics, disinterested crowds, and sweet, sweet chartered jets.
