However,agentic state theory does not consider other possibilities regarding why people obey against their conscience. Zimbardo's research could indicate that Milgram had detected signs of cruelty amongst his p's,and this is why he chose them. In Zimbardo's experiment,within just a few days,the guards inflicted cruelty on prisoners. Therefore,it could be argued that personality (dispositional) factors are instead the reason why people obey orders,as some people might have a naturally more obedient personality that others,making them more capable of committing cruel acts. Invalid explanation.
