By engineering a "fast track" to closeness, the study redefined how psychologists understand the development of the human social identity.

In 1997, researchers Arthur Aron, Melinat, Aron, Vallone, and Bator published a seminal paper in the Personality and Social Psychology Bulletin titled "The Experimental Generation of Interpersonal Closeness: A Procedure and Some Preliminary Findings".
