- Milgram - focuses on how individuals are affected by situational factors. Ps shocked a person up to 400v - potentially death. These were normal people so it would be seen as a result of the situation and the figure of authority being high.
- Piliavin - focus on cost-reward matrix which focuses on human behaviours cognitive processes when put in different social events. These affect the way they behave - diffusion of responsibilty (more people = less responsibility).
- Farrington - most important risk factors are poverty and poor school performance which can be related to peers. Additionally social class will influence criminality.
Strengths and Weaknesses:
Point - Practical interventions Example - Reicher and Haslam Comment - Sometimes hard to change behaviour as people have free will
Point - Good reliability Example - Piliavin Comment - Experiements can jeapordise ecological validity
Point - Takes blame away from individual Example - Milgram Comment - detereministic, nomothetic conclusions
Point - Reductionist Example - Farrington Comment - fails to look at internal behaviours
