<P> A post-experimental debriefing is now considered an important ethical consideration to ensure that participants are not harmed in any way by their experience in an experiment . Though Zimbardo did conduct debriefing sessions, they were several years after the Stanford Prison Experiment . By that time numerous details were forgotten; nonetheless, many participants reported that they experienced no lasting negative effects . Therefore, under current standards, the debriefing process should occur as soon as possible to assess what psychological harm, if any, may have been done and to rehabilitate participants, if necessary . If there is an unavoidable delay in debriefing, the researcher is obligated to take steps to minimize harm . </P> <P> Psychologists Alex Haslam and Steve Reicher conducted the BBC Prison Study in 2002 and was published in 2006 . This was a partial replication of the Stanford prison experiment conducted with the assistance of the BBC, which broadcast events in the study in a documentary series called The Experiment . Their results and conclusions differed from Zimbardo's and led to a number of publications on tyranny, stress, and leadership . The results were published in leading academic journals such as British Journal of Social Psychology, Journal of Applied Psychology, Social Psychology Quarterly, and Personality and Social Psychology Review . The BBC Prison Study is now taught as a core study on the UK A-level Psychology OCR syllabus . </P> <P> While Haslam and Reicher's procedure was not a direct replication of Zimbardo's, their study casts further doubt on the generality of his conclusions . Specifically, it questions the notion that people slip mindlessly into role and the idea that the dynamics of evil are in any way banal . Their research also points to the importance of leadership in the emergence of tyranny of the form displayed by Zimbardo when briefing guards in the Stanford experiment . </P> <P> The Stanford prison experiment was in part a response to the Milgram experiment at Yale beginning in 1961 and published in 1963 . </P>
