Which study demonstrates the ally effect in reducing conformity?

• A. Milgram's experiment
• B. Asch's conformity study
• C. Moscovici's study
• D. Zimbardo's prison study

Answer: (B)

The ally effect is about how having a dissenter in a group can reduce conformity by providing social support and easing the pressure to align with the majority. In Asch’s line-judgment studies, participants faced a clear majority giving incorrect answers. When a single ally also gave the correct line, conformity dropped sharply because the dissenter offered a alternative viewpoint and reduced the perceived need to conform. This shows how normative social influence can be undermined by even one ally, helping individuals trust their own judgments. Milgram’s work focuses on obedience to authority, not the presence of an ally reducing conformity. Moscovici studied minority influence and consistency in color perception, which is about how a persistent minority can influence the majority, not the specific ally-delivered reduction in conformity. Zimbardo’s prison study examines how situational roles and deindividuation shape behavior in a simulated prison environment, not the effect of an ally on conformity.
