Types of Conformity
Compliance, identification, and internalization — Kelman's three depths of social influence
Conformity is changing behavior or belief to match a group, and Herbert Kelman (1958) divided it into three increasingly deep forms. Compliance is public behavior change with private disagreement, driven by reward or punishment — it disappears when surveillance ends. Identification is change to maintain a valued relationship with a person or group; it lasts as long as the relationship matters. Internalization is genuine private acceptance, anchored in the person's own value system, and is the most durable. Solomon Asch's line-judgment studies (1951, 1956) demonstrated compliance, with about 75% of participants conforming at least once on unambiguous trials despite the group being clearly wrong. Sherif's autokinetic studies (1935) showed internalization through ambiguous norm-formation.
- Three typesCompliance, identification, internalization (Kelman 1958)
- Asch baseline~37% mean conformity rate; 75% conformed at least once
- Two motivesNormative (fit in) vs informational (be right) — Deutsch & Gerard 1955
- Sherif autokineticNorms form even on illusory stimuli, persist alone
- Group-size effectPlateaus at 3-4 confederates (Asch)
- Cultural variationHigher in collectivist cultures (Bond & Smith 1996, k=133)

Why conformity types matter
- Organizations. Predicting whether new policies will outlast surveillance or stick when leaders leave depends on whether they were complied with or internalized.
- Public health. Mask-wearing or vaccination compliance fades without enforcement; identification or internalization sustains the behavior.
- Education. Surface compliance with classroom rules differs from internalized academic values; only the latter predicts long-term outcomes.
- Marketing. Identification campaigns (lifestyle branding) build deeper loyalty than discount-driven compliance.
- Therapy. Internalized change in cognitive-behavioral therapy outlasts client-pleasing compliance with the therapist.
- Politics. Vote suppression vs ideological persuasion — different conformity depths produce different durabilities.
- Conflict resolution. Peace agreements anchored only in compliance collapse; those rooted in identification or internalized norms last.
Common misconceptions
- Conformity is always bad. Most cooperative behavior, traffic norms, and social trust depend on it; only blind conformity to harmful norms is problematic.
- Asch participants were duped. Most knew the answer was wrong; their conformity was conscious accommodation, not perceptual error.
- Compliance and conformity are the same. Compliance is one of three depths; treating them as equivalent obscures durability differences.
- Strong individuals never conform. Asch found roughly 75% conformed at least once; the bias is broad, not a marker of weak character.
- Internet anonymity ends conformity. Online conformity is robust — upvote cascades and pile-ons mirror Asch dynamics with strangers.
- Bigger groups always increase pressure. Effects plateau around three or four; what matters more is unanimity than sheer size.
Frequently asked questions
What are the three types?
Compliance is going along publicly while disagreeing privately, driven by rewards or sanctions. Identification is changing because you value membership in a group or relationship — you adopt the views as long as the relationship matters. Internalization is true acceptance of the new view because it fits your own value system. The three differ in depth, durability, and what removes them. Kelman (1958) introduced this taxonomy in a seminal Journal of Conflict Resolution paper.
What did Asch find?
Solomon Asch (1951, 1956) had participants judge which of three lines matched a target. Confederates unanimously gave wrong answers on 12 of 18 critical trials. About 37% of judgments conformed to the wrong majority and roughly 75% of participants conformed at least once. Most reported they knew the answer was wrong — pure normative compliance. Variation in confederate unanimity mattered more than group size beyond three or four.
Normative vs informational influence?
Deutsch and Gerard (1955) split conformity motives in two. Normative influence is conforming to fit in and avoid social rejection — it produces compliance. Informational influence is conforming because others seem to know more — it produces internalization, especially under ambiguity. Sherif's autokinetic experiment showed informational influence; Asch's line task isolated normative influence by removing ambiguity.
Does group size matter?
Up to a point. Asch found conformity rises sharply from 1 to 2 to 3 confederates and then plateaus. Latane's social impact theory (1981) predicts diminishing returns: each added person contributes less. A single ally — even one who gives a different wrong answer — drops conformity dramatically (to about 10%) because unanimity is broken.
Are there cultural differences?
Yes. Bond and Smith's (1996) meta-analysis of 133 Asch-type studies across 17 countries found higher conformity in collectivist cultures (Asia, Africa, South America) than individualist ones (US, UK, Western Europe). Effect sizes ranged roughly 25-58%. Conformity in the US has also declined since the 1950s, paralleling broader individualist trends.
What's a real-world example?
Adolescent peer drinking shows all three. A teen who drinks at a party while wishing they could leave is complying. One who drinks because friend-group identity demands it is identifying. One who comes to genuinely believe drinking is fun and worthwhile has internalized. Each predicts different behavior away from the group: only internalization persists when peers are absent.
How can conformity be reduced?
Explicit minority dissent, even by one person, is the strongest tool — it breaks unanimity. Anonymous responses cut normative pressure. Pre-commitment to a position before hearing others reduces drift. Diverse-background groups conform less. In organizations, structured devil's-advocate roles or independent first-pass votes (used by some juries and surgical teams) reduce groupthink and hidden compliance.
