Answer:
During the Stanford prison experiment, the participants' acceptance of the fictional social roles they had been assigned to such an extent that they subscribed to norms that could be considered as morally reprehensible and acted according to the scripts they had about the context of imprisonment.
Explanation:
Both guards and prisoners enacted their social roles by accepting that guard were in charge and prisoners had to obey.
The way all of them acted derived from scripts developed from the common knowledge about imprisonment: guards became aggressive and cruel, while the prisoners resorted to trashing their cells as a way of rebellion.
This experiment relates to everyday life because it demonstrates that blindly following social norms can be dangerous and one should always keep a critical perspective.
Philip Zimbardo, the conductor of the Stanford Prison Experiment in 1971, has established a comparison between that event and the Abu Ghraib prison in Iraq, in which army troops and CIA personnel abused the prisoners of war in 2003, so that´s a great example of a recent event in which people started fulfilling a role and became abusive.
