13.1 Principles of Social Influence

Social influence shapes our behavior in countless ways. From conformity to obedience, we often adjust our actions to fit in or follow authority. This topic explores the psychological mechanisms behind these phenomena and how they impact our daily lives.

Understanding social influence is crucial for navigating social interactions. We'll examine key principles like reciprocity, scarcity, and social proof, as well as specific techniques used to gain compliance. Recognizing these tactics can help us make more informed decisions.

1 of 3

• Conformity involves changing one's behavior to match the expectations of a group or society
  • Occurs due to desire for social acceptance or belief in group's superior knowledge
  • Can be conscious or unconscious
  • Includes both public compliance and private acceptance
• Asch's line experiment demonstrated conformity in group settings
  • Participants often gave incorrect answers to match group consensus
• Obedience refers to following direct orders or commands from an authority figure
  • Milgram's shock experiment revealed high levels of obedience to authority
  • Participants continued administering shocks despite apparent harm to others
• Factors influencing obedience include perceived legitimacy of authority and gradual escalation of requests

Compliance and Its Mechanisms

• Compliance involves changing behavior in response to a direct request
  • Differs from conformity as it requires an explicit ask
  • Can be achieved through various persuasion techniques
• Social influence tactics often used to gain compliance
  • Reciprocity principle (returning favors)
  • Commitment and consistency (aligning with past actions)
  • Liking (agreeing with those we find appealing)
• Compliance can be short-term or lead to lasting attitude changes
• Reactance may occur when individuals feel their freedom is threatened
  • Can result in non-compliance or opposite behavior

Factors Affecting Social Influence

Social Norms and Informational Influence

• Social norms guide behavior within a group or society
  • Descriptive norms indicate what most people do in a situation
  • Injunctive norms specify what ought to be done
• Informational influence occurs when people rely on others for accurate information
  • More likely in ambiguous situations or when unsure of correct behavior
  • Can lead to internalization of new beliefs or attitudes
• Social proof principle suggests people look to others' actions for guidance
  • Particularly effective in uncertain or novel situations
  • Explains phenomena like bystander effect and pluralistic ignorance

Normative Influence and Authority

• Normative influence stems from desire for social approval and acceptance
  • Can lead to public compliance without private acceptance
  • More prevalent in cohesive groups or when behavior is visible to others
• Authority figures exert strong influence on behavior
  • Cialdini's principle of authority explains tendency to obey legitimate experts
  • Symbols of authority (uniforms, titles) can increase compliance
• Milgram's variations demonstrated factors affecting obedience to authority
  • Proximity of authority figure
  • Legitimacy of the institution
  • Presence of dissenting peers

Reciprocity and Scarcity

• Reciprocity principle creates sense of obligation to return favors
  • Widely used in marketing and fundraising (free samples, small gifts)
  • Can lead to compliance with larger requests after receiving small favor
• Scarcity principle increases perceived value of limited resources
  • Creates urgency and fear of missing out
  • Explains effectiveness of "limited time offers" and exclusive products
• Both principles exploit psychological tendencies for fairness and loss aversion
• Can be combined with other influence tactics for greater effect

Compliance Techniques

Sequential Request Strategies

• Foot-in-the-door technique involves making a small request before a larger one
  • Initial compliance increases likelihood of agreeing to subsequent requests
  • Based on self-perception theory and consistency principle
  • Effective for charitable donations and volunteer recruitment
• Door-in-the-face technique starts with an extreme request followed by more moderate one
  • Large initial request is typically refused
  • Subsequent smaller request seems more reasonable in comparison
  • Exploits reciprocity principle and contrast effect
• Both techniques manipulate perception of requests and social obligations
  • Can be combined or used in sequence for greater effectiveness
  • Ethical considerations in using these techniques for persuasion

Additional Compliance Strategies

• Low-ball technique involves getting agreement before revealing full costs
  • Often used in sales (car dealerships, subscriptions)
  • Relies on commitment and consistency principle
• That's-not-all technique adds incentives to initial offer before response
  • Creates perception of getting a better deal
  • Utilizes reciprocity and contrast principles
• Ingratiation involves making oneself likeable to increase compliance
  • Flattery, similarity, and cooperation can enhance likeability
  • More effective when perceived as genuine
• These techniques highlight importance of framing and presentation in persuasion
• Understanding these strategies can help individuals recognize and resist unwanted influence attempts
