3. The participants did not engage with a meaningful situation in which there were real inequalities of resources and power. The researchers however provide evidence that prisoners did resent their subordinate position from the start of the study and that the guards’ initial conversations focused on the power of the situation.
4. The variables upon which the researchers’ predictions focused (the planned interventions) were not responsible for the effects obtained. Or in other words were the changes in behaviour that occurred a result of the independent variables? The researchers note that their multiple data sources (behavioural and psychometric) enabled them to check whether participants did spontaneously reacted to the interventions. The researchers argue that their quan & qual data suggest that they did.
