In 1971, StanÂford psyÂcholÂoÂgy proÂfesÂsor Philip ZimÂbarÂdo underÂtook a study to deterÂmine whether sitÂuÂaÂtions deterÂmine behavÂior or whether a person’s disÂpoÂsiÂtion leads to behavÂior regardÂless of their sitÂuÂaÂtion. As seen in the above trailÂer for the StanÂford Prison ExperÂiÂment, a new film adapÂtaÂtion of Zimbardo’s conÂtroÂverÂsial study, it was explained thusÂly: peoÂple actÂed like prisoners–lashing out at authorÂiÂty, angry, maladjusted–purely by dint of being put in prisÂons. And peoÂple abused their authorÂiÂty when put in the posiÂtion of authorÂiÂty. The hypothÂeÂsis had its basis in the past: the action of Nazi guards at the conÂcenÂtraÂtion camps. The results have ramÂiÂfiÂcaÂtions through to the present: witÂness the conÂfesÂsions of the guards who torÂtured inmates in Abu Ghraib.
The trailÂer plays like a psyÂchoÂlogÂiÂcal thriller, but so far it looks true to the record. Prof. ZimÂbarÂdo–havÂing just earned tenure at StanÂford (and played in the film by BilÂly Crudup)–chose 24 healthy stuÂdent subÂjects and ranÂdomÂly assigned them either the role of guard or of prisÂonÂer. The PsyÂcholÂoÂgy DepartÂment’s baseÂment was turned into a mock prison, with holdÂing cells, guard rooms, soliÂtary conÂfineÂment, and an exerÂcise yard. CamÂeras recordÂed all that went on, observed by ZimÂbarÂdo and his crew. The “guards” could come and go accordÂing to shifts, but the “prisÂonÂers” could not. While the “guards” could not use physÂiÂcal force on the “prisÂonÂers,” they could use as many psyÂchoÂlogÂiÂcal tacÂtics as posÂsiÂble to break the will of their felÂlow stuÂdents. HowÂevÂer, the “prisÂonÂers” were not told exactÂly what would hapÂpen to them. When, on the first day, the “prisÂonÂers” were “arrestÂed” in the mornÂing, stripped, searched, shaved and deloused, they were already in a state of shock. An earÂly docÂuÂmenÂtary exists on the experÂiÂment and its results here:
SufÂfice it to say (and you may have seen this comÂing) the stuÂdent guards realÂly got into their roles, and the “prisÂonÂers” rebelled. All the while Prof. ZimÂbarÂdo wantÂed to keep going for the planned one to two weeks. Only because of the objecÂtions of ChristiÂna Maslach, a gradÂuÂate stuÂdent and Prof. Zimbardo’s girlÂfriend, did the group abanÂdon the study after six increasÂingÂly frightÂenÂing days. (ProvÂing as well that Prof. ZimÂbarÂdo was affectÂed by the experÂiÂment in ways simÂiÂlar to his subÂjects, as he was unable to iniÂtialÂly stop someÂthing out of conÂtrol.)
The study was fundÂed by the U.S. Office of Naval Research to “study antiÂsoÂcial behavÂior.” The stuÂdent subÂjects were paid $15 a day for their help and half quit the experÂiÂment before it was finÂished. All of the guards stayed on. As detailed in the offiÂcial FAQ on the study, none of the stuÂdents showed any lastÂing trauÂma, though Prof. ZimÂbarÂdo said:
“I was guilty of the sin of omisÂsion — the evil of inacÂtion — of not proÂvidÂing adeÂquate overÂsight and surÂveilÂlance when it was required… the findÂings came at the expense of human sufÂferÂing. I am sorÂry for that and to this day apolÂoÂgize for conÂtributÂing to this inhuÂmanÂiÂty.”
The experÂiÂment is now used in psyÂcholÂoÂgy textÂbooks as an examÂple of the “psyÂcholÂoÂgy of imprisÂonÂment.” Prof. ZimÂbarÂdo turned his sciÂence to helpÂing peoÂple, lookÂing at proÂmotÂing heroÂism in daiÂly life, helpÂing vetÂerÂans norÂmalÂize into social life, workÂing with shy peoÂple, and, comÂing full cirÂcle, tesÂtiÂfyÂing durÂing the court marÂtial of Sgt. Ivan “Chip” FredÂerÂick, who was charged with crimes durÂing his time at Abu Ghraib. ZimÂbarÂdo has since retired and recentÂly advised on the upcomÂing film. ChristiÂna Maslach latÂer marÂried Prof. ZimÂbarÂdo and is curÂrentÂly Vice Provost for UnderÂgradÂuÂate EduÂcaÂtion at the UniÂverÂsiÂty of CalÂiÂforÂnia, BerkeÂley.
And if Prof. Zimbardo’s experÂiÂment sounds a bit like StanÂley MilÂgram’s 1961 experÂiÂment in obeÂdiÂence to authorÂiÂty, well, it’s no coinÂciÂdence. StanÂley MilÂgram and Philip ZimÂbarÂdo were high school friends.
HowÂevÂer, there’s some interÂestÂing difÂferÂences. For one, the “vicÂtims” of MilÂgram’s experÂiÂment were actÂing the elecÂtric shocks they supÂposÂedÂly received. Despite that levÂel of fakÂery, MilÂgram was denied tenure at HarÂvard. The City UniÂverÂsiÂty of New York GradÂuÂate CenÂter, on the othÂer hand, knew a psyÂcholÂoÂgy superÂstar when they saw one and gave him tenure.
