-The '''shadow effect''' occurs when two players each score less points by playing on the same team than they would playing solo. It is a direct result of the fact that every question can be answered by, at most, one player on a team.

-When more than one player is on a team, each player's knowledge base overlaps, however slightly, with each other player's knowledge base.  However, only one player on that team can buzz in and earn points on a tossup.  Therefore, two players whose knowledge bases overlap significantly will each see a large decrease in their [[PPG]] relative to if they had been on separate teams, while two players who specialize in different areas will each see a smaller decrease.  This decrease in PPG is known as the shadow effect.
-The shadow effect is a function of each player's knowledge base and each player's aggressiveness.  However, as a player's knowledge base cannot easily be quantified, an exact formula for the shadow effect cannot be derived.
-The assumption that the shadow effect is roughly the same for all groups of two players is a fundamental flaw in [[PATH]].  Nevertheless, PATH is often considered a more accurate indicator of a player's ability than PPG, which does not account for the shadow effect.
