The Effects of Social Identity Threat on Reactions
to Normative and Deviant Group Members:
A Subjective Group Dynamics Approach1
Abstract: The present research draws from the postulates of subjective group dynamics theory
(SGDT) (Marques, Abrams, Paez, & Hogg, 2001; Marques & Paez, 2008) and previous research on
the black sheep effect (Marques, Abrams, & Serodio, 2001; Marques & Yzerbyt, 1988). We found
support to the SGDT hypothesis that the extreme differentiation between normative and deviant
in‑group members is determined by the motivation to guarantee the in‑group’s positive distinctiveness.
In our study, participants derogated deviant in‑group members and upgraded normative in‑group
members in comparison to respectively similar out‑group members, when the in‑group’s positive
distinctiveness was undermined by an unfavorable inter‑group comparison. In contrast, when
participants were ensured about the in‑group’s positive distinctiveness, they favored both in‑group
members in comparison to the out‑group targets. These results are consistent with SGDT, and are
at odds with an explanation of extreme intra‑group differentiation as a result of the violation of
positive in‑group expectancies (cf. Biernat, Vescio, & Billings, 1999).
Key words: black sheep effect, deviance, social identity, social influence, subjective group dynamics
Guy Fawkes was an English Catholic involved in the failed attempt to assassinate King
James I in 1605. Marshall Henri Philippe Pétain was the Head of State of France who
collaborated with the Nazi regime during World War II. Mordechai Vanunu is a former
Israeli nuclear technician who in 1986 publicly revealed details of his country’s nuclear
weapons program. These are illustrations of famous persons who were convicted for high
treason. They were vilified and despised in their countries. They were also sentenced to
severe penalties, including life imprisonment and death.
In order to understand why individuals despise and antagonize in‑group traitors, we
must understand the reasons why they reject in‑group deviant members in general. By
“deviant” we mean a member of a social group who behaves against the group’s valued
norms (Marques, Abrams, Paez, Hogg, 2001; Marques & Paez, 2008). Treason is a
particular case of deviance as it goes against a general norm of loyalty to the group. In

contrast, normative group members are those who behave accordingly with the group’s
norms and, as such, they generally stand out less than the deviants.
According to subjective group dynamics theory (Marques, 2010; Marques, Abrams,
Paez, et al., 2001; Marques & Paez, 2008), hostility toward deviant in‑group members is
illustrated by the evaluative differentiation process coined the black sheep effect, by which
individuals upgrade normative in‑group members and downgrade deviant in‑group members
as compared to similar out‑group members (e.g., Marques & Paez, 1994; Marques, 2010;
Marques & Yzerbyt, 1988; Marques, Yzerbyt, & Leyens, 1988). SGDT accounts for the
black sheep effect as an outcome of people’s motivation to ensure that fellow in‑group
members are consonant with the prescriptive standards that legitimate their beliefs on the
in‑group’s positive distinctiveness (Marques, 2010; Marques, Abrams, & Serodio, 2001;
Marques & Paez, 2008).
Indeed, previous research on subjective group dynamics has showed that group members
are generally favorable toward normative in‑group members, while being more hostile
towards deviant in‑group members than deviant out‑group members, when it is necessary
to achieve or to restore the in‑group’s positive distinctiveness (e.g., Marques, Abrams, &
Serodio, 2001). Our goal with the present study is to follow up that research in support of
the idea that individuals favor normative in‑group members and derogate deviant in‑group
members, more than similar out‑group members, when the in‑group’s positive distinctiveness
is undermined. We suggest this is a way to achieve and sustain a positive social identity. In
addition, we analyze how the motivation for a positive social identity can determine the
advocacy of strategies of social influence, either socializing or punitive, toward in‑group
deviants (cf. Pinto, Marques, Levine, & Abrams, 2010).
Subjective group dynamics and the black sheep effect
Subjective group dynamics theory (SGDT) draws from the general postulates of the social
identification approach, including social identity theory (e.g., Tajfel, 1978; Tajfel & Turner,
1986) and self‑categorization theory (e.g., Turner, Hogg, Oakes, Reicher, & Wetherell,
1987) to which it adds a perspective about the role of deviance in structuring social relations
(cf. Marques, Abrams, Paez, et al., 2001; Marques, Abrams, & Serodio, 2001; Marques
& Paez, 2008). According to the social identification approach, individuals strive to achieve
and to sustain a positive social identity by achieving and maintaining a positive differentiation
as compared to relevant out‑groups in specific social situations (Tajfel, 1978). Namely,
individuals assimilate themselves to an in‑group prototype and, as a result, develop in‑group
favoring attitudes, which materialize in terms of biased judgments and discriminatory
behavior regarding out‑groups and their members (Tajfel, Billig, Bundy, & Flament, 1971;
Tajfel & Turner, 1986; Turner, et al., 1987).
SGDT, on its side, aims to extend the social identity approach to the analysis of
intra‑group differentiation processes that occur in inter‑group contexts. Based on research
on the black sheep effect, SGDT sustains that intra‑group differentiation may allow individ
uals to subjectively validate the in‑group, namely by reinforcing their commitment to the
norms that legitimate their beliefs on the in‑group’s positive value as compared to an
out‑group (e.g., Marques, 2010; Marques, Abrams, & Serodio, 2001; Marques & Paez,
2008; Pinto, et al., 2010).
Since the initial work by Marques and colleagues (Marques & Yzerbyt, 1988; Marques,
et al., 1988), the black sheep effect was found in a wide variety of social contexts, under

a range of different experimental conditions (e.g., Biernat, et al., 1999; Branscombe,
Wann, Noel, & Coleman, 1993; Breakwell, Vignoles, & Robertson, 2003; Eidelman &
Biernat, 2003; Hichy, Mari, & Capozza, 2008; Jetten, Summerville, Hornsey, & Mewse,
2005; Khan & Lambert, 1998; Lewis & Sherman, 2010; Nesdale & Brown, 2004). In
this line of research, some authors proposed alternative accounts for the occurrence of the
black sheep effect. In particular, Biernat, Vescio, and Billings (1999) relate the downgrading
of in‑group deviant members to the aversive emotions triggered by the violation of higher
positive expectancies toward the in‑group than the out‑group by deviant in‑group members.
Below, we focus on the SGDT’s account on the black sheep effect. In a follow‑up section,
we analyze Biernat, Vescio, and Billings’ (1999) research and alternative explanation.
Descriptive focus and prescriptive focus
in judgments of in‑group members
SGDT suggests that judgments of in‑group members ensue from the articulation of a
descriptive and a prescriptive focus on the perception of individuals’ behavior (Marques,
2010; Marques, Abrams, Paez, et al., 2001; Marques & Paez, 2008). Descriptive focus
emerges when perception is driven by the accentuation of inter‑category differences and
intra‑category similarities. In such cognitive contexts, individuals simultaneously concentrate
on perceived similarities between instances of the same category and on perceived differences
between instances of contrasting categories (Haslam & Turner, 1992; Oakes, Haslam, &
Turner, 1994; Turner, et al., 1987). Social groups thus become cognitively construed in
terms of those attributes that, in each particular social context, best represent group
prototypes (Turner, et al., 1987), and individuals (including the self) come to be perceived
as in‑group or out‑group members (Marques, Paez, & Abrams, 1998).
According to the social identification approach, group prototypes correspond to the
groups’ contrasted positions along dimensions that SGDT defines as descriptive norms.
Examples of descriptive norms may include skin color when ethnic differentiation between
groups is relevant, or particular chants voiced by soccer fans in support for their respective
teams during a match (Marques, Abrams, & Serodio, 2001; Marques, et al., 1998; Pinto,
et al., 2010). The position occupied by any individual on a descriptive dimension defines
that individual’s membership to one of the salient groups in those particular contexts.
However, there can be situations in which, after inter‑group distinctiveness is cognitively
established through descriptive focus, individuals’ attention is directed at group members’
behavior on dimensions that are not relevant for inter‑group differentiation and category
inclusion, but that define the value ascribed to the groups and their members. Examples of
such dimensions, which SGDT designates as prescriptive norms, include “honesty”, “fair‑play”,
“solidarity”. Prescriptive norms stand for moral conventions (cf. Cialdini, Reno, & Kallgren,
1990; Reno, Cialdini, & Kallgren, 1993) that are common to every social group and thus
do not allow for inter‑group differentiation. However, they help define the value assigned
to the group and hence the perceived legitimacy, or subjective validity (Pinto, et al., 2010),
of group members’ beliefs on the positive value they ascribe to their group.
SGDT suggests that deviant behavior triggers a prescriptive focus on the part of the
observers, who will devote their attention to the extent to which the actor contributes
positively or negatively to the overall value assigned to their group. When the actor is an
in‑group member, deviant behavior jeopardizes belief on the relative superiority of the
in‑group. As a result, this member should be strongly derogated, as a means to legitimize

the in‑group’s positive identity in comparison to the out‑group. This process leads to extreme
evaluative appraisals of deviant and normative in‑group members, who are respectively
threatening and supportive to the in‑group’s positive distinctiveness, in comparison to
out‑group similar targets, i.e. the black sheep effect.
Identity threat and the black sheep effect
In line with the above reasoning, some research suggests that the black sheep effect is more
likely to occur when the in‑group’s image is undermined and it seems necessary to restore
its positive stand (e.g., Marques & Paez, 1994; Marques, Abrams, & Serodio, 2001). For
example, Marques, Abrams, and Serodio (2001, Experiment 3) categorized participants in
two groups based on a bogus imagination test. Some participants were then informed that their
in‑group type of imagination was undoubtedly superior to the other (a secure positive identity
scenario), whereas other participants were told that it was not sure which type of imagination
was superior, and that the purpose of the study was to clarify this issue (an insecure positive
identity scenario). All participants were then presented with four group members who
adopted a normative ethical opinion and one member who adopted a deviant opinion.
Results showed that only in the insecure positive identity scenario, participants judged
the normative in‑group member more favorably than the normative out‑group member and
derogated the deviant in‑group member in comparison to the deviant out‑group member.
In the secure positive identity scenario, participants favored both in‑group members in
comparison to the out‑group members. These results thus illustrate the idea that group
members are more inclined to reject deviant in‑group members and uphold normative
in‑group members when their identity’s positive value is undermined than when it is secure
by comparison with a relevant out‑group.
Expectancy violation and the black sheep effect
Biernat, Vescio and Billings (1999) proposed an account of the black sheep effect based on
a theoretical rationale alternative to subjective group dynamics theory. According to these
authors, the derogation of in‑group deviants ensues from a state of negative mood arising
from a perceived violation of positive in‑group expectancies. To test this hypothesis, Biernat,
Vescio and Billings (1999) had White female university students playing a team game with
a White or Black female confederate. Participants were told that the better their team result
was, the more chances they had in winning a prize. Confederates delivered a high or low
quality performance. After the game, participants were asked to judge their partner’s
performance, competence and warmth and whether their partner’s performance had violated
their expectancies. Before and after the game, participants were also asked to indicate the
extent to which they were experiencing each of a series of positive and negative emotions.
According to the results, low‑performing White partners elicited more expectancy violation
and more negative mood change, in comparison to both the low‑performing Black and the
high‑performing White partners. Furthermore, mediation analysis confirmed that perceived
expectancy violation led to negative mood, which in turn led to more negative evaluations.
In our view, it seems difficult to support the expectancy violation hypothesis relying on
the Biernat, Vescio and Billings’ (1999) study. Because this study included only White
participants, there is a possibility that the significant correlation between expectancy

violation and negative mood was not related to social identity concerns per se, but to
race‑based stereotypes. Participants might expect the White confederate to be a competent
partner, not because she was a team member, but because she was White (cf. Whitehead,
Smith, & Eichhorn, 1982). Thus, a study including also Black participants would be advised
to account for this alternative possibility. Also, and perhaps more importantly, the expectancy
violation measure was collected after participants interacted with the partner and after
having answered to the mood and attitudinal scales. Thus, the question of causality remains
open. Biernat, Vescio and Billings (1999) propose that the perception of expectancy violation
leads to more negative moods and more negative evaluations of in‑group deviant members.
However, according to the temporal ordering of the variables in their study, it is possible
that the opposite causal order may be right.
The expectancy violation hypothesis is a compelling explanation for the black sheep
effect and can account for some instances of social discrimination, perhaps not necessarily
against in‑group deviants, but toward any in‑group or out‑group members who fall short of
group expectations. Thus, we believe this hypothesis deserves further scrutiny and should
be studied as an alternative explanation to the in‑group’s positive distinctiveness hypothesis
supported by subjective group dynamics theory and research (cf. also Pinto, et al., 2010).
Advocated strategies toward in‑group deviant members
More recent research on SGDT has showed that, in association with evaluations of normative
and deviant in‑group members, individuals advocate harsher social control strategies toward
deviant in‑group members, and that this is associated with their motivation to defend the
in‑group’s identity. For example, Pinto, et al. (2010, Study 3) informed students from two
courses that they would organize a debate between students issuing from both courses.
Participants were presented with in‑group or out‑group course normative and deviant targets
as potential debaters. Based on Levine and Moreland’s (e.g., 1994) group socialization
model, these targets were presented either as new to their course (new members), or as
well‑established students (full members), or as students who wished to leave their course
(marginal members). Participants were asked to evaluate a target who advocated a normative
opinion and a target with a deviant opinion about the topic for the debate, and to advocate
a series of socializing and punishing strategies as to deal with the target whom they agreed
the least (all participants chose the deviant).
Pinto and colleagues (2010) found that the normative in‑group full member was the most
favorably evaluated of all targets, and the deviant in‑group full member was the most
unfavorably evaluated of all targets. In addition, the more negatively participants evaluated
the deviant in‑group full member, the more they advocated a punishing reaction toward this
target, whereas the more negatively participants evaluated the deviant in‑group new member,
the more they advocated a socializing reaction toward this target. These findings suggest
that the appraisals of deviant in‑group targets can be related to more socializing or punitive
strategies, as a function of the level of threat the targets pose. More specifically, because
in‑group full members are held responsible for upholding the group’s values and image
(Levine & Moreland, 1994), any deviant behavior on their account poses a strong threat to
the in‑group’s image. Thus, the group should be highly motivated to punish in‑group full
members’ deviant behaviors. In contrast, deviant in‑group new members pose less of a
threat to the group’s image, and thus trigger less punishing and allow more socializing
reactions. In the present study, we follow this research by analyzing how punishing and

socializing strategies of social influence toward in‑group deviants can lead to the validation
of a positive in‑group image.
Overview and hypotheses
We test reactions to group members in an inter‑group context which is either favorable or
unfavorable to the in‑group, namely a situation where participants are informed about the
in‑group’s positive value and a situation where they are informed of the in‑group’s negative
value to an out‑group. This methodology allows us to test the following competing hypothesis,
either (1) that the extreme reactions toward deviant and normative in‑group targets, which
are characteristic of the black sheep effect, are triggered in the presence of undermining
information to the in‑group’s image to a relevant out‑group (cf. Marques, Abrams, & Serodio,
2001), or (2) that the black sheep effect is triggered when in‑group deviant members contradict
the in‑group’s higher standards in comparison to an out‑group (cf. Biernat, et al., 1999).
We presented two inter‑group settings to students of Psychology and Educational Sciences
courses. In one setting, the in‑group (Psychology or Educational Sciences) course had more
deviant members in comparison to the other course (Threatening setting), whereas in the
other setting (Secure setting), the in‑group course had less deviant students. We asked
participants to judge a deviant and a normative target, who were either in‑group course, or
out‑group course students. In line with previous research (e.g., Marques, Abrams & Serodio,
2001), we expected the black sheep effect to emerge from the threatening, but not from the
secure setting, i.e. participants would derogate the in‑group deviant member as compared
to the out‑group deviant member, and would be more favorable to the in‑group normative
member than to the out‑group normative member.
In addition, we asked participants to indicate their degree of support for a socializing
and a punishing strategy aiming to reduce deviance in the in‑group. Previous research on
subjective group dynamics theory confirms that the support for socializing and punishing
strategies towards in‑group deviants is related to the implications of the deviant’s behavior
for positive group identity (Pinto, et al., 2010, Study 3). Individuals can give more support
toward a socializing reaction aimed at convincing in‑group deviants to change their views,
if the in‑group deviant members pose little threat to the in‑group’s image (e.g., because
they are new members); and adhere more to a punishing reaction, as to remind in‑group
deviants of the social costs of their deviance, if the in‑group deviant members pose a strong
threat to the in‑group’s image (e.g., because they are full‑time members). Either way, the
support for the influencing strategies toward in‑group deviants should help individuals to
assure a more positive view of the in‑group. In our study, we tested this hypothesis with
an exploratory analysis on how the support for socializing and punishing collective strategies
aiming to reduce in‑group deviance can lead to a more positive view of the in‑group.
Method
Participants and design
Participants were 24 Psychology and 26 Educational Sciences students attending the Univer
sity of Porto, Portugal (80% female, M = 22.12 years, DP = 6.88). A 2 (Inter‑group Setting:
Threatening vs Secure) × 2 (Target’s Group: In‑group vs Out‑group) × 2 (Target’s Stance:

Normative vs Deviant) mixed design was used. Group Comparison and Target’s Group were
between‑participants factors, and Target’s Stance was a within‑participants factor1
.
Procedure
Participants were approached in public places in the Faculty building and asked to answer
a survey about prejudiced attitudes and discrimination among university students. Participants
were informed that a preliminary survey had measured Psychology and Educational Sciences
students’ opinions about several minority groups in Portugal. This survey had, supposedly,
highlighted the percentage of students in both courses who supported a discriminatory policy
against Gypsies, namely “exiling Gypsies who are condemned for criminal activities”.
Agreement with this policy had been previously shown to be infrequent and considered as
undesirable by a different sample of individuals from the same population2
. According to
the Inter‑group Setting manipulation, participants either read that the in‑group course had
proportionally more, or less students, who supported the discriminatory policy than the
other course (18% vs 3%, or 18% vs 33%, respectively).
Before being presented with the information about the percentages of group members,
participants answered to a series of social identification questions. Next, they were asked
to evaluate two students who had given an opinion about the matter. The first target student
supported the discriminatory policy, and declared that Gypsies are “untrustworthy and prone
to engage in criminal behavior” (this statement was pre‑tested to be undesirable by another
sample of individuals from the same population3
). The second target student opposed the
1. Participant’s course was similarly distributed across conditions χ2
(3, N = 50) < 1. Participant’s sex
and age were unbalanced across conditions, χ2
(3, N = 50) = 7.55, p = .056 and F(1, 46) = 4.020,
p = .051, respectively. Apart from the change in their respective magnitudes, the analysis involving
participants’ course, sex and age as covariates in the design of the experiment was similar to the analysis
reported in the results section. We thus disregarded Participant’s course, age and sex in the analysis.
2. We asked 16 Psychology and 12 Educational Sciences students about their opinion on five
anti‑Gypsies discriminatory policies, one of them being “exiling Gypsies who are condemned for
criminal activities”. We asked participants to estimate the percentage of students within their course and
Faculty that would support such a policy. Results indicated that students regarded the support for that
policy as infrequent within their own course (M = 18.14%, SD = 17.71) and Faculty (M = 26.50%,
SD = 21.57). Both results were significantly below a 50% threshold, t(27) = 9.52, p < .001 and
t(27) = 5.76, p < .001, respectively. Also, we asked participants about their personal support for the
policy on a 7‑point scale (1 = I totally disagree, 7 = I totally agree). Participants did not support
the discriminatory policy (M = 2.34%, SD = 1.28, significantly below the middle point of the scale,
t27 = 6.97, p < .001). There were no significant differences between Psychology and Educational
Sciences students for the estimation of the frequency of support within the Faculty and personal support,
t(26) always < 1.01, ns. But Educational Sciences students tended to regard support for the policy
as more infrequent within their course (M = 10.92%, SD = 11.76) in comparison to Psychology
students (M = 23.56%, SD = 19.76, t26 = 1.97, p = .060). Both these results were significantly
below 50%, t(15) = 5.35, p < .001 and t(11) = 11.51, p < .001, respectively.
3. We asked 11 Psychology and 13 Educational Sciences students about their opinion on four statements
of different university students whose courses were unidentified. They were asked to evaluate each
statement, on a scale between 1 = “negative” and 7 = “positive”. We retained two statements for the
main study: One statement that was evaluated favorably (M = 5.46%, SD = 1.02, significantly above
the middle of the scale, t23 = 7.00, p < .001) and another that was evaluated unfavorably (M = 2.29%,
SD = 1.04, significantly below the middle of the scale, t23 = 8.03, p < .001). We submitted these
scores to a Participant’s Course (Psychology and Educational Sciences) × Statement (Favorable and
Unfavorable) analysis of variance, with the latter measure as a within‑subject factor. Participants
favored one statement over the other, as shown by the significant Statement main effect, F(1, 22)
= 77.31, p < .001. Participant’s Course and Course × Statement yielded no significant effects,
both F(1, 22) < 1. A further t‑test conducted on the two scores, after reversing the items for the

discriminatory policy, by noting that “any discriminatory judicial policies can only lead to
more marginality and exclusion” and stressing the values of a “multi‑cultural, democratic
and cohesive society” (pre‑tested as desirable). Both the deviant and the normative targets
were presented as attending either the same course as the participant (in‑group) or the other
course (out‑group). Participants were then asked whether they would support two civic
groups formed by students of the same course as theirs. Both groups aimed to reduce
prejudice among students of their course, but whereas one group advocated a persuasive
strategy, the other advocated a punishing strategy to be applied to prejudiced in‑group
students. In the end, participants answered to a second set of social identification questions.
Dependent Measures
Social identification. Participants indicated their degree of identification with their course
at two different times. First, after being informed of the goals of the study and before the
experimental manipulation, participants answered the following items: “Do you like the
students of your course?” (1 = I don’t like them at all; 7 = I like them a lot), “To be a
student of your course is an important part of your identity?”, “Do you trust the students
of your course?”, “Do you treasure the friendship of the students of your course?”, “Do
you believe students of your course are among the most qualified at the University of
Porto?”, “Do you think about yourself frequently as a student of your course?”, “Do you
believe students of your course are among the most altruists at the University of Porto?”
(1 = not at all; 7 = totally). Second, at the end of the survey: “Do you think you have
similar attitudes and values with the generality of the students of your course?”, “Do you
believe the students of your course have high levels of morality?”, “Is it important to you
to be seen as a student of your course?” (1 = not at all; 7= totally), and “What would
you feel if you heard someone badmouthing students of your course?” (1 = very well;
7 = very bad). We averaged the answers to these items to a pre‑Identification and a
post‑identification scores (Cronbach´s α = .72, and .67, respectively). This scores were
significantly correlated, r = .634, p < .001.
Evaluation of targets. Participants were asked to evaluate each of the two target
‑students, on the following item: “What is your impression of this student?”
(1 = „negative”, 7 = „positive”).
Advocated strategies of social influence. This measure was inspired by the Political Action
Intentions Index (cf. Iyer, Schmader, & Lickel, 2007). Participants were presented with
descriptions of two hypothetical civic groups composed by students of the same course as theirs,
each one advocating specific strategies aimed at reducing prejudice in their course. One group
advocated persuasive strategies (“informative measures, like conferences, debates, cultural
events”), whereas the other group advocated punishing policies (“disciplinary measures,
like sanctions, fines, punishments”) to be applied to prejudiced in‑group students. Participants
were asked to indicate their willingness to support each group in four ways, ranging from less
to more costly: “joining the group’s mailing list”, “signing the group’s manifesto”, “joining
the group”, and “recruiting other students to join the group” (1 = not at all; 7 = totally).
Thus, two sets of measures were averaged to respectively assess participants’ willingness to
participate in actions to support the persuasive group (four items, α = .88) and to support
the punishing group (four items, α = .96).
unfavorable score (1 = 7; 2 = 6; … 6 = 2, 7 = 1), was non‑significant (t23 = 1.10, ns), suggesting
that the favorable statement was as better evaluated as the unfavorable one was depreciated.

Results
Pre‑identification
To check for participants’ identification with the in‑group course before experimental
manipulations, we ran an Inter‑group Setting (Threatening vs Secure) × 2 (Target’s Group:
In‑group vs Out‑group) analysis of variance on the pre‑identification score. There was a
significant difference in this measure between Targets’ Group conditions (In‑group: M = 4.69%,
SD = .68 vs Out‑group: M = 5.45%, SD = .39, F(1, 46) = 22.99, p < .001, η2
= .33).
This difference can only be attributed to chance, as the score was taken before participants
received any information related to the experimental manipulations.
Evaluations
We expected the black sheep effect to occur more strongly in the unfavorable inter‑group
comparison than in the favorable inter‑group comparison condition. To check for this
prediction, we conducted an analysis of covariance (ANCOVA) Inter‑group Setting × Targets’
Group × Target’s Stance on evaluation of normative and deviant members, while controlling
for the effects of pre‑identification.
The ANCOVA showed a significant Inter‑group Setting × Targets’ Group × Target’s Stance
interaction, which was consistent with our main hypothesis, F(1, 46) = 5.51, p = .023,
η2
= .111
(see Figure 1). We decomposed this interaction according to the Inter‑group Setting
condition. The Targets’ Group × Target’s Stance interaction was marginally significant in the
threatening setting and was not significant in the secure setting, F(1, 47) = 3.55, p = .066,
η2
= .07 and F(1, 47) = 2.20, ns, respectively.

In the threatening setting, we found a pattern which was consistent with the black

(M = 1.33%; DP = .49) than the deviant out‑group member (M = 1.92%, DP = .86;

= .06) and evaluated more positively the normative in‑group
member (M = 5.42%; DP = 1.08) than the normative out‑group member (M = 4.85%,
DP = .90; F1, 46 = 4.62, p = .037, η2
= .09).
In the supportive setting, there was a Targets’ Group main effect, F(1, 46) = 6.56,
p = .014, η2
= .12. An exploratory analysis of the simple effects suggested that the Targets’
Group effect was mainly due to the deviant target’s evaluation, which was higher toward the
in‑group deviant (M = 2.50%, DP = 1.02) than toward the out‑group deviant (M = 1.64%,
DP = .81, F1, 46 = 3.92, p = .054, η2
= .08). There was no significant difference
between the evaluations of the normative in‑group (M = 5.50%, DP = 1.29) and normative
out‑group members (M = 5.55%, DP = 1.51, F1, 46 = 2.59, p = .11, η2
= .05).
Evaluative judgments, social control strategies, and identity motivations
We expected that the derogation of in‑group deviant members, the favorable evaluations of
in‑group normative members, and support for the social control strategies would be
significant predictors of social identification, but we were not sure about the relative
predictive power of each independent variable in each experimental condition. We thus ran
multiple regression analyses within each condition defined by Inter‑group Setting and Target’s
Group. Post‑identification was the dependent measure, and pre‑identification, evaluative
judgments toward each target, and support for the persuasive and punitive strategies were
predictors1
. Due to the exploratory nature of this analysis, we ran forward selection stepwise
regressions (cf. Ho, 2006).
In the conditions in which participants evaluated out‑group members, the predictors did
not explain post‑identification (criterion: probability of‑F‑to‑enter ≤ .05). In the threatening
setting and evaluation of in‑group targets’ condition, post‑identification was predicted by
support for the persuasive strategy, β = .60, t = 2.57, p = .025. In this condition, the
more group members supported the persuasive civic group to deal with in‑group deviance,
the more they identified after with the in‑group. In the secure setting and evaluation of
in‑group targets’ condition, post‑identification was predicted by pre‑identification, β = .70,
t = 4.95, p = .001, followed by the evaluation of the normative in‑group member, β = .36,
t = 2.53, p = .032. The more favorably participants evaluated the normative in‑group
member, the more they identified after with the in‑group. In sum, these results are consistent
with our predictions. They show that evaluation of in‑group members and support for social
control strategies allow individuals to warrant the positive value of the in‑group.
Discussion
The present results indicate that participants favored a normative in‑group member and
derogated a deviant in‑group member in comparison to similar out‑group targets when the
in‑group’s positive distinctiveness was threatened. In contrast, when the in‑group’s positive
1. In contrast to previous research on SGDT, we analyzed social control over in‑group deviance in
general and not in particular group deviant members. Our present analysis is thus exploratory and
does not focus on means. The complete data is available from the first author upon request.

distinctiveness was secure, the deviant in‑group member was less negatively evaluated than
the deviant out‑group target. The non‑emergence of the black sheep effect in the latter
condition seems at odds with Biernat, Vescio and Billings’ (1999) idea that derogation of
deviant in‑group members ensues from the violation of higher positive expectancies about
the in‑group than the out‑group.
Indeed, in light of this latter explanation, participants would derogate the in‑group
deviant more than the out‑group deviant members, especially in the secure setting. Following
the information that there are less instances of in‑group deviance than out‑group deviance,
expectations should be more positive toward the in‑group than the out‑group, and a particular
instance of in‑group deviance would be perceived as more unexpected than an instance of
out‑group deviance. According to the expectancy violation explanation, this setting would
thus be more fitting to a black sheep effect, than the threatening setting, where the in‑group
deviant member is more in accordance to group‑based expectations than the out‑group
deviant member.
In contrast, our results do not support the expected relationships between the evaluation
of group targets, social control over in‑group deviance, and social identification. It is
important to notice that previous research on subjective group dynamics measured the
relationships between evaluations and social control toward particular group deviant members
(Marques, Abrams, & Serodio, 2001; Pinto, et al., 2010). However, our study analyzed
evaluations and social control toward different targets (in‑group or out‑group members, and
in‑group deviance as a whole, respectively). This may have made the resulting patterns
complex and non‑linear. Even so, two significant relationships emerged, which were in
accordance to our predictions. In the secure setting, the more participants favored the
in‑group normative member, the more they valued the in‑group afterwards. Also, in the
threatening setting, the more participants advocated the persuasive strategy to deal with
in‑group deviance, the more they assigned the in‑group a positive value afterwards. Perhaps
these exploratory results justify follow‑up studies on the social motivations behind the
punitive and socializing strategies over in‑group deviants. In addition, follow‑up studies
should include measures about the estimations of in‑group deviant behavior and its impact
on the in‑group’s image, which are important manipulation checks missing from our study.
Going back to our examples at the outset of this work, it is likely that the threats posed
by those historical characters to their nations’ identities are relevant components for a more
general explanation of the harshness of the social reactions they evoked. After all, Guy
Fawkes was tortured and sentenced to death, amidst a vibrant civil conflict for the religious
identity of England. Marshall Pétain was sentenced to death as part of France’s struggle to
exorcise its collaborationist past and to restore a heroic identity. Mordechai Vanunu was
sentenced to a 18 years imprisonment in a country whose national identity seems to be
permanently under threat. Thus, these narratives seem to illustrate SGDT’s postulate that
when social identity is threatened, group members can be strongly depreciative and hostile
toward in‑group deviants.
