Although the results of Elms and Milgram suggest a link between authoritarian personality and obedience, these results are correctional and it is therefore difficult to draw meaningful conclusions about the exact cause of the obedience. In addition, there are many other situational factors that contribute to obedience, including proximity, uniform and location. Therefore, although it is likely that authoritarian personality contributes to obedience, a range of situational variables can affect the level of this contribution.
