Zimbardo and colleagues randomly as

Zimbardo and colleagues randomly assigned male volunteers to play the roles or either guards or prisoners in a 2-week prison simulation experiment.
The students quickly assumed these roles—to such an extent that the researchers ended the experiment after only 6 days.
Many of the guards became quite abusive, thinking of creative ways of verbally harassing and humiliating the prisoners.
The prisoners became passive, helpless, and withdrawn.

Zimbardo dan rekannya acak laki-laki relawan untuk bermain peran atau penjaga atau tahanan di penjara 2 minggu simulasi percobaan.Siswa cepat-cepat berasumsi peran ini — sedemikian rupa bahwa para peneliti berakhir percobaan setelah 6 hari. Banyak penjaga menjadi cukup kasar, memikirkan cara-cara kreatif secara lisan melecehkan dan mempermalukan para tahanan. Para tahanan menjadi pasif, tak berdaya, dan ditarik.
