Contribution
A chapter-length review of the common in-group identity model as it bears on helping, with two new studies. The model says bias falls when members of two groups come to see themselves as one group. The chapter shows this extends to helping, not only to attitudes. It then adds the model’s second shared representation, the dual identity (subgroups within one superordinate group), and reports that a minority member who expresses it is helped less by majority members, not more.
Key insight
A shared identity extends help across a group line, but only in the form the helper prefers. The authors’ White participants valued a common identity with a Black student. When he described himself as “a Black Colgate student”, which includes the common identity, they treated him like one who described himself only as Black. The enlarged “we” that carries helping is the majority’s assimilationist “we”: “The responses of White participants … were positive and prosocial when a Black person identified himself in a way compatible with an assimilation ideology” (p. 204).
Assumptions
- Social identity and self-categorization theory as the basis (p. 193). Bias is in-group favouritism, so moving out-group members inside the boundary moves favouritism to them.
- Majority help as the case that matters (p. 191), since majority members’ help “is more often required”.
- Dual identity cannot be tested from the minority side (pp. 198, 205). A White person saying “I see myself primarily as a White person” would read as racist, so the authors did not run the mirror condition.
- Helping measures are low-cost acts: posters placed, hours volunteered on a form, agreeing to an interview.
Key results
- The 1989 experiment, as reported (p. 194). Relative to a two-group condition, decategorization (separate individuals) reduced bias by making former in-group members less attractive; recategorization (one group) reduced it by making former out-group members more attractive. No numbers are given.
- Dovidio et al. 1997, helping (pp. 194–195). Two laboratory
subgroups (overestimators and underestimators), induced to a one-group
or two-group representation. A taped student, ill and behind on a
project, asked for help placing posters.
- Two Group: more posters for an in-group than an out-group member, Ms = 4.83 vs 2.25.
- One Group: “no bias against original out-group members” (Ms = 3.08 vs 3.92).
- Commons dilemmas (p. 195). Kramer and Brewer 1984: a salient superordinate identity (same city) raised conservation when resources became scarce. Wit and Kerr 2002: contributions to a six-person fund were highest when participants were framed as one group of six, lowest when two three-person subgroups were salient.
- Field study (Nier et al. 2001, Study 2; pp. 195–196). At a
Delaware football game, Black and White interviewers in either
university’s hat asked fans for an interview on food preferences.
- White fans and a Black interviewer: 59% complied with a shared university identity, 36% without.
- White fans and a White interviewer: 44% vs 37%, not significant.
- Too few Black fans to analyse.
- Dovidio, Gaertner & Johnson 1999 (pp. 198–201). White Colgate
students watched a scripted, favourable interview with a Black
confederate who answered “And how do you see yourself?” four ways.
- Prejudice (Brigham’s Attitudes toward Blacks Scale, higher is more prejudiced): common university 1.68, different racial 2.24, dual 2.47, unique individual 2.32. Only the common condition differed from the others.
- Hours volunteered for a Black student organization: common 0.85, unique 0.55, dual 0.30, different 0.25.
- Attitudes did not mediate volunteering; they correlated r = .25 with it.
- The follow-up study (pp. 201–204). The same design with three
conditions (common, dual, different), a request from the confederate
himself, and empathic concern measured (Batson’s adjectives).
- Attitudes toward him: 5.00 common vs 4.33 different and 4.55 dual (p = .08 across conditions).
- Empathic concern: 3.35, 2.58, 2.47 (p = .04).
- Posters agreed to: 2.73, 0.57, 0.46 (p = .01).
- Different and dual did not differ on any measure; common was higher than the two combined on each (ps < .04).
- Mediation: with empathic concern added, its effect on helping was β = .34, p < .01, and the condition effect fell from β = .46 to .35 (Sobel z = 1.99, p < .05), still significant. Attitudes did not mediate.
- Proposed mechanisms (pp. 205–206), untested here.
- In-group projection (Mummendey and Wenzel 1999): majority members take their group’s standards as the superordinate category’s, so a minority member stressing his subgroup looks deviant.
- Identity threat: a dual identity undermines the dominant culture’s hegemony.
- Culture: in Portugal, one-group recategorization reduced bias more for Black children and dual identity more for European Portuguese children (Rebelo et al. 2005).
Claims
| id | claim | strength | support |
|---|---|---|---|
| C1 | Recategorizing two groups as one removes in-group bias in helping toward original out-group members | moderate: one laboratory experiment and one field experiment by the authors, plus two commons-dilemma studies by others; no sample sizes given | pp. 194–196 |
| C2 | A salient common identity increases White people’s compliance with a Black person’s request | weak to moderate: one field study, a cheap request, Black fans not analysable | Nier et al. 2001 |
| C3 | Majority members help a minority member who expresses a dual identity less than one who expresses only the common identity, and no more than one who expresses only his subgroup | moderate: two studies, consistent pattern; one confederate, one campus | pp. 198–204 |
| C4 | Empathic concern partly mediates the effect of the other’s expressed common identity on helping, and attitudes do not | weak to moderate: one study, partial mediation, cross-sectional mediator | p. 204 |
| C5 | Discordance between majority and minority preferred representations causes the negative reaction | weak: proposed; the design cannot separate discordance from the dual identity reading as exclusionary, as the authors say | p. 205 |
Concepts
- recategorization: changing who counts as in-group by making a more inclusive category salient, so former out-group members are inside it.
- decategorization: reducing the salience of group boundaries so members are seen as separate individuals.
- common in-group identity (one group): both groups seen as one superordinate group.
- dual identity: original subgroup identities and the common identity active at once (“Black Colgate student”).
- assimilation versus multiculturalism: the ideologies the one-group and dual-identity representations parallel (p. 197).
- in-group projection: taking one’s own group’s standards as those of the superordinate category.
Connections
- Gaertner et al. 1989 (LIT-1710) and Gaertner et al. 1993 (LIT-1709), both unread. The chapter gives one sentence of the first and none of the second. It restates the model, the four representations and the two routes of the 1989 study.
- Self-categorization theory (THEORY-1114). The model draws on it. Recategorization is a change in the level of self-categorization, induced by the experimenter. The chapter does not use metacontrast or measure depersonalization.
- Biel (NOTE-1299) studies European common in-group identity among football fans by survey. Nier et al.’s stadium study is the model’s experimental case with fans.
- Cialdini et al. (LIT-1728) and Batson et al. (LIT-1700). The chapter measures empathic concern with Batson’s items and finds a shared identity raises it.
Bearing on the record
- The owner’s thesis (CLAIM-491). The chapter bears on it in
three ways. These are inferences; the authors do not discuss
selflessness.
- It supports the thesis’s prediction that helping follows the “we”. Moving an out-group member inside a shared category raised help to the in-group level, in the laboratory and at a stadium. The boundary was moved by the experimenter, not by what participants cared about, which is the kind of manipulation the thesis needs.
- It qualifies what “larger self” means. The “we” that extends help is the helper’s own representation of it. A minority member who claims the common identity on his own terms is helped as if outside it. If the larger self is the helper’s self, the thesis predicts this; but then the extended self is not a fact both parties share. It is one party’s category, and it may extend only to those who fit its prototype.
- It shows a shared identity working through empathy. In the second study the common identity raised empathic concern and empathy carried part of the effect on helping.
- Batson’s objection (CLAIM-494). The mediation runs from identity to empathy to helping. That is the reverse of Batson’s design, which holds merging fixed and finds empathy still predicts helping. The inference: identity and empathy are not independent routes. A shared identity raises empathy, so controlling for merging may remove part of empathy’s effect. The residual direct effect of condition (β = .35) shows identity also acts by another route.
- The triviality objection (CLAIM-492). Recategorization is a manipulation of the self’s extent that does not go through caring: the experimenter changes the category, and helping follows. That is the shape of answer the objection asks for. But no study here measures self-categorization; the manipulation is assumed to work, and caring (empathy) is downstream of it.
- The group entity versus a category (TERM-096). The model’s common identities are categories (a university, a city, “Americans”), not group entities.
- A dated note should be added to CLAIM-491. Proposed text: “Dovidio et al. (NOTE-1286) review experiments in which recategorizing two groups as one removed in-group bias in helping, in the laboratory and at a football stadium. The shared identity raised empathic concern, which carried part of the effect. But White participants helped a Black student who called himself a Black Colgate student no more than one who called himself Black. If helping follows an extended self, the self it follows is the helper’s category, and a dual identity can fall outside it.”
- No THEORY filed.
- No ML instruction.
Limitations
- No sample sizes, test statistics or design details for most studies; the chapter reports means and p-values selectively. The 1997 One Group means are not labelled in-group and out-group.
- One confederate, one campus, Colgate, for both dual-identity studies.
- Cheap helping. Posters, hours promised on a form, a short interview.
- The mirror condition is missing, so whether the effect is discordance or the dual identity reading as exclusionary is open (p. 205).
- Not the originals. The 1989 and 1993 papers’ designs, measures and data are not reported.
- Typos.
- “majority and majority groups” for majority and minority (p. 197).
- “handle a sealed envelope” for hand (p. 202).
- “Westchester State University” (pp. 195–196); the university is West Chester.
- Wolsko, Park and Judd is cited as 2006 (p. 197) and 2000 (p. 207); these may be two papers, but the copy has no reference list to check.
Open questions
- Does recategorization extend costly help, not only cheap help?
- Would measuring self-categorization (for instance with the overlap circles) show that it, not empathy, carries the effect of a shared identity on helping, as the thesis would predict?
- Do minority members extend help across a group line under a dual identity, as the model would predict from their preference?
