Controls: Just as scientists and researchers attempt to put parameters on their experiments in order to limit such factors as margin of error and unreliability, PPI investigators will exact such controls on the environment of the investigation so that our analysis will lead to more reliable results. Controls may be as simple as limiting the number of individuals within the venue, to more sophisticated matters such as triangulation of audio sources. Controls are considered an essential feature to any application of the Scientific Method.
