- Bearing in mind the outcomes of this research, could an attempt to replicate or extend our study be ethically justified?
- If you had come into the study at a particular point, would you have realised that Prisoners and Guards had started off as matched groups? How have the groups changed over time and why?
- Why did the Guards in our study not use many of the powers that they had? Do these reasons apply to groups in situations outside this study?
- Would giving the Guards any more powers have made any difference to their behaviour?
- Why did the Guards fail to organize themselves? Could this problem have been anticipated (e.g., on the basis of findings from the SPE)?
- What does the impact of the introduction of a new Prisoner on Day 5 tell us about the impact of individuals on society and history?
- At the start of our study, nearly all the participants – Guards as well as Prisoners – rejected even a mild form of inequality. But by the end they were moving towards acceptance of a far more unequal regime. Why did this happen?
