Lecture Notes: Conformity, Norms, and Social Influence
Norms and Conformity: Concepts and Cultural Context
Core idea: conformity involves adjusting thoughts, feelings, or behaviors to align with group norms or expectations.
Cultural orientation shapes conformity goals:
Interdependent/collectivistic cultures: emphasis on harmony, belonging, and fitting in with the group.
Independent cultures: emphasis on distinctiveness and individual autonomy.
These orientations influence when and how people conform in social settings.
Hedonic costs of conformity (Dan Ariely & Levov, turn-of-the-century study):
Story concept: ordering first or last, or ordering the same item (e.g., beers) in a group setting.
Idea: conforming to group behavior can carry cost or benefit in terms of personal satisfaction or social ease.
Practical takeaway: social influence can shape mundane choices (e.g., orders in a casual setting).
Number of choices and conformity: Paul Rosen and colleagues (2006):
Study setup: telephone interviews with N=6000 representative adults across multiple countries.
Task: choose between 10 vs 50 ice cream flavors.
Key finding: a higher share preferred 50 flavors, but strong cross-country variation existed.
Cross-country patterns:
USA: about half preferred 50 flavors, showing substantial demand for variety but not universal.
Continental Europe (e.g., Switzerland, France): lower preference for 50 flavors, suggesting stronger communal/collective eating norms.
UK: intermediate attitude, with the smallest value for the 50-flavor option among the studied pairs.
Correlation: expectations about preference for more choices were weakly and positively correlated across countries.
Interpretation: Americans and the British tend to accommodate individual differences more than continental European cultures, which may be more oriented toward shared or collective choices.
Real-world example and cognitive costs of choice:
Casa Gelato (Vancouver) example with 238 flavors illustrates how extreme variety can be appealing yet cognitively costly.
Jam taste-testing studies: choosing from 24 kinds vs 6 kinds:
People who chose from fewer options (6 kinds) were more likely to buy a jam of that kind.
High choice set depletes self-regulatory resources and cognitive load, reducing subsequent task performance.
Link to Barry Schwartz: The Paradox of Choice (talk around ~11 min) discusses how more options can reduce satisfaction and increase indecision, especially for subsequent tasks (e.g., choosing jeans).
Why we conform: potential benefits and costs
Benefits: ease, predictability, social harmony, easier coordination.
Costs: ostracism risk if one deviates; cognitive load from many options; potential loss of personal preference satisfaction.
Ostracism and belonging: evolutionary perspective
Ostracism = social exclusion by a group (peer rejection, bullying, silent treatment, inattentiveness).
Evolutionary argument: detecting and avoiding ostracism has survival value; belonging to a group historically linked to safety and resource access.
Psychological system: sensitivity to social exclusion feeds conformity to regain belonging and functional group integration.
Descriptive vs Prescriptive Norms (Injunctive Norms)
Descriptive norms: what people typically do in a given situation.
Example: at work, a 10:00 a.m. coffee break is the usual behavior; observing colleagues taking breaks around that time reflects a descriptive norm.
Prescriptive (injunctive) norms: what people should do; societal or cultural expectations.
Example: it’s expected to say ‘please’ and ‘thank you’ when requesting help; reflects a prescriptive norm.
Both norms influence behavior and can shape conformity, but their accessibility and salience affect how strongly they sway actions.
Accessibility of norms:
Norms that are highly accessible in the immediate environment exert stronger influence on conformity.
Classic Experiments in Social Influence
Cialdini’s littering experiment (norms and behavior in a real setting)
Design: parking garage environments manipulated to be clean or littered; confederates either littered or did not litter; a prescriptive-norm condition with a disapproving confederate (non-littering).
Findings (descriptive norm salience):
In a clean environment, when a confederate picked up litter, participants were less likely to litter.
In a littered environment, when a confederate littered, participants were more likely to litter (descriptive norm effect).
Pro-littering behavior increased in high-norm-salience littered environments; pro-clean behavior increased in low-salience clean environments.
Prescriptive-norm condition: disapproval of littering reduced littering, highlighting social disapproval as a salient injunctive norm.
Quantitative highlight: in the high-norm-salience littering condition, approximately 54 ext{ ext{%}} of participants littered (illustrating powerful descriptive-norm effects).
Milgram’s “Looking Up” study (public conformity to others’ behavior)
Setting: busy New York City sidewalk; confederates stood looking up at a building.
Manipulation: number of confederates looking up ranged from 1 to ~15.
Outcome: higher the number of confederates, greater the percentage of pedestrians who looked up; with more confederates, the behavior spread through the crowd (public conformity in a real-world, ambiguous situation).
Interpretation: social influence is automatic and often unconscious; people rely on others to infer appropriate behavior when unsure.
Real-world analogy: early pandemic shopping behavior where people followed others’ actions in uncertain situations.
The Look Up study demonstrates how quickly a behavior can spread as a function of group size and ambiguity.
Perception Biases in Social Norms
False consensus effect: overestimating the extent to which others share one's traits or attitudes.
Example: extroverts assuming most others are extroverted; vegetarians assuming most people are vegetarian.
Consequence: strengthens the sense of normalcy and belonging with one’s own group, reinforcing conformity with perceived norms.
Pluralistic ignorance: misperceiving that one’s private attitudes or behaviors are different from those of others in the group.
Example: in situations where no one asks a question, individuals may assume they are the only one who does not understand, leading to continued non-clarification and conformity to perceived norms.
Examples in research:
Prentice & Miller (university students, alcohol consumption):
Method: measured personal attitudes toward campus drinking and estimated peers’ attitudes and consumption.
Finding: a discrepancy existed; many students were less comfortable with heavy drinking than they believed their peers were.
Gender difference: males perceived peers to be more comfortable with drinking than females did.
Behavioral consequence: conformity to perceived norms led to heavier drinking to align with what students thought was the norm.
Lambert et al. (romantic relationships and risky behavior):
Studied how perceptions of a partner’s attitudes and behaviors influenced individuals’ own risky sexual behavior and substance use.
Result: individuals who perceived their partners as engaging in or approving of risky behaviors were more likely to engage in similar behaviors.
Role of perceived norms and relationship commitment in shaping health-related behavior.
Modern social discourse example:
A Twitter post about anti-lockdown protests referenced false consensus and pluralistic ignorance in public opinion: some minority groups may believe they are in the minority (pluralistic ignorance) while appearing as a majority in public discourse; others may believe they are a majority (false consensus) and overestimate support for their views.
Takeaway: Misperceptions of norms can drive conformity and public behavior, sometimes with harmful social or political consequences.
Minority Influence: The Blue-Green Slide Study (Moscovici-style Experiment)
Objective: examine whether a consistent minority can influence majority opinions.
Participants: 172 female participants; groups of 6 (4 true participants + 2 confederates) in a color-perception task.
Procedure: participants viewed 36 slides showing shades of blue and estimated whether each slide was blue or green.
Conditions:
Consistent minority: the two confederates consistently claimed that all slides were green, even though they were blue.
Inconsistent minority: the confederates claimed slides were green only two-thirds of the time.
Findings:
Consistent minority condition: about 8 ext{ ext{%}} of genuine participants reported seeing a green slide; about rac{1}{3} of participants reported seeing at least one green slide.
Inconsistent minority condition: influence was significantly weaker, with only about 1 ext{ ext{%}} reporting green.
Conclusion: a consistent, confident minority can influence majority opinions; inconsistency reduces the minority’s influence.
Implications: highlights how minority groups can foster social change under the right conditions; consistency and confidence are key to exerting influence.
Summary of Key Takeaways (Mini Lecture)
Social influence operates through both nonverbal cues and observed norms, acting as social glue to provide certainty and control.
Private conformity can arise from observing norms to satisfy the need for belonging and avoid ostracism; public conformity is more visible and context-dependent.
Norm accessibility and group size amplify conformity: higher norm salience and larger groups increase conformity, but diminishing returns occur beyond a certain group size (and task/environment matters).
False consensus effect and pluralistic ignorance can distort perceptions of norms, leading to misaligned behavior with actual attitudes.
Perceived social norms strongly influence behaviors, including health-related and relationship behaviors; misperceptions can contribute to harmful conformity.
Minority influence is most effective when the minority is consistent, confident, and perceived as legitimate; extreme inconsistency undermines influence.
Real-world relevance: during crises (e.g., pandemics, social movements), individuals look to others to infer appropriate action, which can accelerate or hinder collective responses.
Ethical considerations: many classic experiments used deception (e.g., Moscovici, Milgram) and confederates; researchers discuss the ethical implications and the need for careful design and debriefing.
Practical and Ethical Implications
In organizational and public policy contexts, understanding norms can guide interventions to promote prosocial behavior (e.g., litter reduction, health behaviors).
Be mindful of normative influence when designing campaigns; emphasize injunctive norms (social approval) alongside descriptive norms to maximize beneficial outcomes.
Recognize that misperceptions about norms can lead to unhealthy conformity; corrective information and normative feedback can help realign behavior with actual norms.
Ethical note: researchers must balance the insights gained from social influence studies with the ethical obligation to minimize harm and ensure informed consent where possible; deception requires thorough debriefing and consideration of participant welfare.
Connections to Foundational Principles
Social learning: conformity emerges from observing and emulating others in ambiguous situations.
Norms and culture: descriptive vs injunctive norms shape behavior across cultures and situations.
Cognitive load and self-regulation: numerous choices can deplete resources and alter subsequent performance.
Evolutionary perspective: the human tendency to conform and detect ostracism has roots in group survival and social cohesion.
Minority influence and social change: consistent, credible minorities can shift majority opinions, revealing mechanisms of social transformation.
