Social Influence

Core Concepts & Manifestations

Social influence refers to the ways in which individuals change their behavior, attitudes, or beliefs as a result of real or imagined pressure from others. It is a fundamental concept in psychology.

1

Conformity

Adjusting one’s thoughts, feelings, or behaviors to align with those of a group or social norm.
2

Compliance

Changes behavior publicly while privately disagreeing (superficial and temporary change).
3

Obedience

Following direct commands from an authority figure.
4

Minority Influence

A smaller group or an individual influences the majority to adopt a new attitude or behavior.

Types of Conformity

Solomon Asch’s line judgment experiments are seminal in demonstrating conformity, highlighting two major psychological types:

🤝

Normative Social Influence (NSI)

Conforming to be liked or accepted by the group. It involves compliance with group norms even if privately one disagrees.
🧠

Informational Social Influence (ISI)

Conforming because one believes others have more accurate information, especially in ambiguous situations, leading to internalisation where private beliefs change.

Asch's Line Judgment Study

The Power of Group Pressure

In a task where participants identified which of three comparison lines matched a target line in length, confederates gave incorrect answers. Around 75% of participants conformed at least once, and the overall conformity rate was about 33%.

Asch’s research also identified factors influencing conformity rates: group size (larger groups increase conformity but plateau after about 4 people), unanimity (a break in the consensus reduces conformity), and task difficulty (harder tasks increase conformity due to greater ISI).

Techniques to Increase Compliance

Compliance involves superficial and temporary change and often occurs to gain rewards or avoid punishments. Classic studies demonstrate these techniques:

1

Foot-in-the-Door Technique

Making a small request first (likely to be accepted), followed by a larger request.
2

Door-in-the-Face Technique

Making a large request first, expecting refusal, then making a smaller, more reasonable request.
3

Low-Ball Technique

Agreeing to a request but then changing the terms to be less favorable after compliance.

Milgram's Obedience Experiments (1963)

Obedience to Authority

Obedience involves following direct commands from an authority figure. Participants believed they were delivering electric shocks to another person when instructed by an experimenter. Despite signs of distress from the “learner” (a confederate), around 65% of participants delivered the highest shocks, revealing how strong obedience can be, even when causing apparent harm.

Situational Factors in Obedience

⬆️
Factors that Increase Obedience Proximity of authority figure: Being physically close to the authority figure increased obedience. Location: Prestigious settings (e.g., Yale University) increased obedience compared to less prestigious places. Legitimacy of authority: Authority figures wearing symbols of power (e.g., lab coat) increased obedience.
⬇️
Factors that Decrease Obedience Proximity of victim: Closer proximity decreased obedience. Obedience research raises ethical issues related to deception and participant distress.

Key Processes of Minority Influence

Minority influence leads to internalisation and social change through these processes, often requiring the minority group to display specific behavioral styles:

✓

Consistency

Moscovici’s study showed that consistent minorities were more successful in influencing participants than inconsistent minorities.
✓

Commitment

Showing dedication to the view (e.g., making personal sacrifices).
✓

Flexibility

Being open to compromise.

Social Psychological Explanations

These theories explain the underlying mechanisms of why and how social influence occurs:

⚛️

Social Impact Theory (Latane)

Influence depends on strength (importance of the group to an individual), immediacy (closeness in time and space), and the number of people in the group.
🤖

Agentic State Theory

Individuals experience an “agentic shift,” moving from autonomous state to agentic state (seeing self as an agent for authority). This reduces feelings of responsibility for actions.
👑

Legitimacy of Authority

People obey when authority is perceived as legitimate, often linked to institutional roles or social hierarchies.

Summary of Factors Affecting Influence

Various factors modify the rate and type of social influence experienced by individuals:

1

Group Size

Both conformity and obedience increase with larger groups up to a point.
2

Anonymity

When responses are anonymous, conformity decreases.
3

Culture

Collectivist cultures show higher conformity rates than individualistic cultures due to emphasizing group harmony.
4

Personality

Some people are more resistant to social influence, e.g., those with high internal locus of control or high self-esteem.

Ethical Issues in Research

🛑
Major Concerns (Milgram, Asch) Deception: Participants are often misled (e.g., Milgram, Asch) which raises concerns about informed consent. Protection from Harm: Experiments like Milgram caused significant psychological stress. Right to Withdraw: Participants must be made aware they can leave at any time.
🛡️
Modern Requirements & Mitigations Confidentiality: Participant data should be protected. Modern research studies use debriefing to reduce negative effects and obtain retrospective consent for use of data.

Real-World Applications

🎯

Practical Use Cases: Understanding peer pressure effects in adolescence. Marketing and advertising use compliance techniques. Authority influence explains obedience in contexts like military or workplace. Minority influence is crucial in social movements and promoting progressive attitudes.

Research Limitations & Evaluation

Evaluating the strengths and limitations helps determine the generalizability of findings:

🧐
The insights are deep, but aren't many studies limited by artificial settings?
💡
Experiments like Asch and Milgram involved artificial settings and samples biased towards Western males, which may limit generalizability. Nevertheless, evidence from field studies supports many laboratory findings.

🌸 Social Influence Quiz

1. Which type of social influence involves changing your public behavior but privately disagreeing?

Compliance involves superficial change to gain approval or avoid conflict without private acceptance.

2. Solomon Asch’s experiments demonstrated:

Participants conformed to clearly wrong answers given by confederates.

3. Which factor does NOT increase conformity?

A break in group unanimity usually reduces conformity.

4. The Agentic State Theory explains:

Agentic state reduces personal responsibility, increasing obedience.

5. True or False: Minority influence leads to public compliance but no private belief change.

Minority influence leads to internalisation, altering private beliefs.

6. Which compliance technique involves making a large request first followed by a smaller one?

The large request is expected to be refused, making the smaller one more likely accepted.
