Minority Influence: Moscovici's Study (AQA A-Level Psychology): Revision Notes
Minority Influence: Moscovici's Study
Minority influence occurs when a small group of people successfully changes the attitudes, beliefs or behaviours of a larger majority group. Serge Moscovici conducted a landmark study in the 1960s that demonstrated how minorities could influence majorities under specific conditions.
Moscovici's research was groundbreaking because it challenged the prevailing assumption that influence only flows from majority to minority groups. This study opened up an entirely new area of social psychology research.
Moscovici's study details
Participants: Randomly selected participants and confederates
Aim: To observe how minorities can influence a majority
Procedure:
- Laboratory experiment using groups of six people
- Each group contained two confederates (minority) and four real participants (majority)
- All participants viewed 36 blue slides, each displaying different shades of blue
- Participants were asked to identify whether each slide was blue or green
- Confederates deliberately responded "green" on two-thirds of trials, creating a consistent minority viewpoint
- The frequency of times real participants agreed that slides were green was recorded
- A control group with no confederates was also tested for comparison
Key Findings:
- When confederates gave consistent answers, approximately 8% of participants agreed the slides were green
- When confederates answered inconsistently, only about 1% of participants said slides were green
- This demonstrated that consistency is crucial for minority influence to be effective
Key factors for effective minority influence
Consistency
Moscovici's research revealed that consistency is the most important factor for minority influence. There are two types:
Diachronic consistency means the minority group maintains the same position over time without changing their views. This persistence makes the majority take notice and consider that the minority view might have merit.
Synchronic consistency occurs when all members of the minority group share identical views and support each other. This unified front strengthens the minority's credibility.
When minorities remain consistent, they trigger the augmentation principle - the majority assumes the minority must be confident in their position to maintain it despite opposition. This creates doubt in majority members and opens them to influence.
Real-World Example: Civil Rights Movement
The Civil Rights Movement demonstrated both types of consistency:
- Diachronic consistency: Maintained the same message of equality over decades
- Synchronic consistency: Leaders like Martin Luther King Jr. and other activists presented unified positions
- This consistency triggered the augmentation principle - people began to think "they must really believe in this cause to face such opposition"
Commitment
The majority is more likely to be influenced when the minority demonstrates strong commitment to their position. Passionate advocacy and confidence suggest to the majority that the minority view has validity worth exploring. This commitment encourages deeper consideration of the minority perspective.
Flexibility
While consistency is vital, minorities must also show flexibility to avoid appearing rigid or extremist. A completely inflexible minority may seem unreasonable or attention-seeking. Strategic flexibility makes the minority appear more rational and cooperative, increasing their persuasive power.
Research by Martin et al (2003) found that people were less willing to change opinions after hearing minority views compared to majority views, suggesting minority messages are processed more deeply and have more enduring effects.
Evaluation
Strengths
Methodological Advantages:
- Controlled laboratory conditions allowed precise measurement of minority influence effects
- Clear quantitative findings (8% vs 1%) demonstrated the importance of consistency
- Replicable methodology that other researchers could verify
- Practical applications for understanding how social movements create change
Weaknesses
Limitations to Consider:
- Artificial task and stimuli - identifying slide colours lacks mundane realism compared to real-world attitude change
- Limited ecological validity - laboratory setting doesn't reflect how minority groups operate in society
- Ethical concerns - participants were deceived about the true nature of confederates
- Cultural and temporal limitations - conducted with specific populations that may not generalise broadly
Key Points to Remember:
- Moscovici's study used blue/green slides to test how consistent minorities could influence majority judgements
- Consistency is crucial - 8% influence when consistent vs only 1% when inconsistent
- Three key factors: Consistency (over time and between members), Commitment (showing passion), and Flexibility (avoiding extremism)
- Laboratory limitations mean findings may not fully reflect real-world minority influence processes
- Social change occurs when minority influence creates snowball effects that gradually transform majority opinion
