What concept did the Stanford Prison Experiment most clearly illustrate?

• A. Individual traits determine behavior entirely.
• B. The environment and assigned roles can produce abusive or submissive behavior.
• C. Authority has little influence on actions.
• D. Group dynamics are irrelevant in controlled settings.

Answer: (B)

The key idea is that situational factors and social roles can powerfully shape behavior. In the Stanford Prison Experiment, ordinary volunteers adopted the roles of guards and prisoners within a realistic prison setting. The environment, the uniforms, the power dynamics, and expectations attached to those roles led guards to behave abusively and prisoners to become submissive and distressed. This shows that actions can be driven as much by context and assigned roles as by personal traits, highlighting how authority and situational pressures shape behavior.

This is why the best choice is that the environment and assigned roles can produce abusive or submissive behavior. The other options misstate the influence of context or authority: behavior isn’t determined entirely by individual traits, authority clearly influenced actions, and group dynamics were central to how the situation unfolded, not irrelevant in a controlled setting.
