Comments on an article by Twenge on the issue of psychological traits that may differ with culture and ethnicity in discussing the partial replication of Milgram's obedience research (Burger, January 2009). But since a major stimulus for Milgram's research was the destruction of European Jewry (Benjamin & Simpson, January 2009; Blass, 2009), what about the "elephant in the room" of differences in European national groups on obedience, aggression, locus of control, and related factors? The five-factor model as applied across cultures offers a way of looking at European national differences in personality (Allik & McCrae, 2004). The results can be used to explore the possibility that personality traits that may be related to obedience might differ partly along cultural lines, with the considerable caveats that such traits probably change over time and generations, are subject to situational and historical variables, and interact with individual differences. The emphasis on situational determinants in discussions of the Milgram paradigm and its partial replication by Burger (2009) should not obscure possible cultural factors. Cultural factors in obedience to authority are worthy of further exploration.
