Reicher and Haslam BBC experiment.

Reicher and Haslam carried out this study to examine the consequences of randomly dividing men into groups of prisoners and guards within a specially constructed institution over a period of 8 days.

For ethical reasons only people who were well-adjusted and pro-social, scoring at low levels on all social and clinical measures were included in the study.

The 15 participants were randomly divided into two groups of 5 guards and 10 prisoners.

One prisoner was not involved at the beginning of the study.

Prisoners were allocated to lockable 3-person cells and participants could be both video and audio recorded wherever they were. There was also daily psychometric testing. Furthermore, daily swabs of saliva were taken in order to ascertain cortisol levels.

The guards had a series of means by which to enforce their authority, including keys to all doors inside the prison, sole access to an upper level, a ‘guards’ station’ with a surveillance system from which they could see into the prisoners’ cells, resources (including snacks and cigarettes) to use as rewards or withdraw as punishments – and, in addition, the ability to put prisoners on a bread and water diet.

The guards also had far better conditions than the prisoners, including superior meals, extra supplies of drinks and snacks…
