The purpose of this brief commentary is to correct some misinformation that appears in many sport psychology writings. As the title of this paper indicates, the author discusses two historical giants in social psychology, Norman Triplett and Kurt Lewin, who are often cited in sport psychology publications. The problem with the typical commentary on these two social scientists and the events they are linked to is that the discussions of them are typically inaccurate, as Strube, Stroebe, and Bedeian indicate and the author next elaborates on.
