The study, led by Claudia Chiarolanza of Sapienza University of Rome together with Stefano Isolani of Guglielmo Marconi University and Danilo Garcia of the University of Stavanger, drew its inspiration from Greek mythology. Nemesis, the goddess of retribution, embodied the outrage that follows perceived violations—a fitting metaphor, the authors argue, for the emotional and social forces that swirl around revenge in romantic relationships. Betrayal within a couple is not merely a private wound; it is a violation of a relational contract, and the response it elicits carries both private and public dimensions. The researchers set out to test whether the perceived legitimacy of a vengeful act depends jointly on the sex of the avenger and the visibility of the act itself.

To do so, the team designed a controlled 2 × 2 factorial experiment. Each of the 908 participants, all Italian adults recruited through social networks and community circles, was randomly assigned to read one of four scenarios depicting a marital betrayal and a subsequent act of revenge. The scenarios varied the sex of the avenger—male or female—and the context of the retaliation—public or private. In the public conditions, the vengeful act unfolded before an audience: one male avenger posted about his wife’s affair in a town’s Facebook group, while one female avenger publicly humiliated her husband and his lover at a company dinner. In the private conditions, the retaliation was directed at the partner alone, such as a message to a small WhatsApp group or throwing a spouse’s belongings out the window. Participants rated how plausible they found each scenario and how likely they would be to act as the avenger did, on five-point scales.

The design was carefully controlled. An a priori power analysis had indicated that at least 299 participants would be needed to detect a medium effect with 90 percent power; the final sample far exceeded that threshold. Randomization checks confirmed that the four groups did not differ in age, education, relationship status, or any of the psychological variables measured. The researchers also collected data on participants’ own sex, mental well-being, impulsivity, dispositional forgiveness, and dispositional vengeance, using well-validated instruments including the Barratt Impulsiveness Scale, the Bolton Forgiveness Scale, the Vengeance Scale, and the Warwick-Edinburgh Mental Wellbeing Scale. Internal consistency was acceptable to excellent across all measures, with the Vengeance Scale reaching a McDonald’s omega of 0.91. All analyses employed robust standard errors and bootstrap estimation with 5,000 samples to guard against violations of normality.

The results on perceived plausibility were subtle but telling. Neither the avenger’s sex nor the context alone significantly shaped how believable participants found the scenario. Instead, the two factors interacted: in public settings, scenarios featuring a female avenger were rated as more plausible than those featuring a male avenger, with a statistically significant difference corresponding to a small effect size (partial eta-squared of 0.008). In private settings, no such difference emerged. The Female/Public condition received the highest mean plausibility rating of 3.48, while the Female/Private condition received the lowest at 3.18. The authors caution that this interaction, though significant, represents a modest variation in social perception rather than a dramatic practical effect.

The picture changed dramatically when participants were asked whether they themselves would act as the avenger did. Here the overall model explained a substantial 20 percent of the variance, and a large main effect of the avenger’s sex emerged: female-avenger scenarios received markedly higher endorsement than male-avenger scenarios in both contexts. Crucially, the gap widened when the act was public. In the public condition, the difference between female and male avengers corresponded to a large effect (d = 0.91), nearly double the moderate effect observed in the private condition (d = 0.44). Descriptively, the Female/Public condition again topped the ratings at a mean of 2.61, while the Male/Public condition sank to the bottom at 1.42. In other words, participants were most willing to imagine themselves taking public revenge as women, and least willing to do so as men.

Perhaps the most important finding is that this pattern survived statistical adjustment. When the researchers re-ran the model controlling for perceived plausibility, participants’ own sex, well-being, impulsivity, forgiveness, and vengeance, the avenger’s sex by context interaction remained significant, with effect magnitudes essentially unchanged. Among the covariates, dispositional vengeance, perceived plausibility, and impulsivity each predicted endorsement, whereas participants’ own sex, well-being, and forgiveness did not. This persistence indicates that the contextual and gendered contribution to vengeance endorsement is not reducible to stable individual differences. Something about the situation itself—who acts and who watches—shapes how acceptable revenge appears, above and beyond the psychological profiles of the people doing the judging.

The authors interpret these results through a communicative-signaling framework. Drawing on work by Boon and Yoshimura, they argue that a vengeful act simultaneously delivers three messages: that an injury has occurred, that the avenger is willing to defend their standing, and that future violations will carry a cost. When the act is enacted before others, this signal becomes more legible and more consequential, because the audience to whom it is implicitly addressed expands. Social media platforms amplify this dynamic further, extending the reach of a retaliatory act far beyond the immediate circles of the avenger and the target. On this view, the public versus private context of revenge is not a peripheral detail but part of what the act means—and the finding that visibility amplifies the difference between female and male avengers suggests that gendered expectations about who may legitimately perform retribution in front of others are woven into those signals.

The study is not without limitations, which the authors acknowledge candidly. The convenience sample was recruited in Italy, limiting generalizability to other cultures; the study lacked a formal manipulation check confirming that participants interpreted the public and private conditions as intended; it was not preregistered; and written scenarios may not capture the emotional intensity of real betrayal. The researchers also note an ethical concern: the scenarios may inadvertently reinforce stereotypical portrayals of the sexes, and future work should incorporate counter-stereotypical narratives and direct measures of gender identity and gender norm endorsement. Still, the practical implications are tangible. Because impulsivity predicted vengeance endorsement, clinical conversations about betrayal may benefit from attention to emotion-regulation strategies of the kind used in cognitive-behavioral interventions. And because the visibility of a vengeful act shaped its acceptability, therapists may want to explore how clients construe the audience and reputational dimensions of their own potential responses to infidelity.

What Project Nemesis ultimately offers is a reframing of one of humanity’s oldest impulses. Revenge, the study suggests, is not simply retaliation—a raw discharge of hurt. It is a socially embedded, communicative process that depends on who enacts it, who witnesses it, and the gendered expectations that surround both. The perceived plausibility and endorsement of vengeful acts arise from the joint contribution of situational cues and dispositional tendencies, consistent with a biopsychosocial model in which fast, emotionally driven reactions are tempered by slower, intentional character processes. As the authors conclude, perceptions of vengeance are not purely reactive but reflect the dynamic interplay of personal characteristics, social context, and the audience to whom the act is, at least implicitly, addressed. In an era when a single post can broadcast a betrayal to thousands, understanding how visibility and gender shape the social calculus of revenge has never felt more urgent.

The review, led by Johanna Ray Vollhardt of Clark University together with Hu Young Jeong of the University of Virginia, Zsolt P. Szabó of Corvinus University Budapest and Eötvös Loránd University, and Khaled Elazab of Clark University, synthesizes decades of research from social psychology, clinical and counselling psychology, liberation psychology, and adjacent disciplines. Its central contribution is a unifying structure: an appraisal–coping framework that organizes the sprawling literature on collective victimization beliefs into the phases long used to understand individual stress — primary appraisal, secondary appraisal, coping efforts, and coping outcomes. By mapping group-level beliefs onto this sequence, the authors offer a technically precise way to predict when collective victimization produces destructive consequences and when it instead gives rise to constructive ones.

The framework begins with primary appraisal, the initial assessment of whether an event threatens the group or offers an opportunity. Applied collectively, this stage encompasses beliefs about the severity, intentionality, and temporal scope of harm. A community may appraise a massacre as an existential threat to its survival, as a historical injustice that demands redress, or as a completed chapter of the past. Each reading carries distinct emotional signatures. Appraisals of ongoing threat generate fear and collective angst — the dread that the group’s future vitality is in jeopardy — whereas appraisals of past injustice can fuel anger, humiliation, or a sense of moral obligation. Research on historical trauma among Indigenous peoples, on the siege mentality documented in intractable conflicts, and on conspiracy beliefs as adaptations to historical trauma all illustrate how primary appraisals shape the psychological terrain on which later responses unfold.

Secondary appraisal follows: the evaluation of what the group can do about the harm. Here the framework incorporates beliefs about collective power, agency, and efficacy. Groups that perceive themselves as powerless may retreat into defensive victimhood, emphasizing their suffering to claim moral standing they cannot secure through strength. Groups that perceive latent strength may convert victimization appraisals into challenge rather than threat, a shift that studies on historical collective trauma suggest can transform intergroup dynamics. The review highlights findings among Black Americans, Kurdish communities, and other groups whose beliefs about ingroup resilience and resistance — the conviction that ‘we have survived before and can resist again’ — operate as psychological resources rather than wounds. These secondary appraisals determine whether coping efforts take the form of avoidance, such as denial and defensive closure, or approach, such as justice-seeking, collective action, and outreach.

The third phase, coping efforts, is where the framework displays its greatest explanatory reach. The authors distinguish among a wide repertoire of strategies that victimized groups deploy, many of which were previously treated as isolated phenomena. Competitive victimhood — the struggle to establish that one’s own group suffered more than its adversary — emerges as an avoidance-oriented strategy that obstructs forgiveness and reconciliation, as demonstrated in studies of Israeli–Palestinian, Bosnian, and other post-conflict settings. By contrast, inclusive victim consciousness, the belief that one’s own suffering connects the group to other victimized groups rather than separating it from them, functions as an approach-oriented coping effort associated with support for refugees, willingness for intergroup contact, and peace activism. The review also integrates less-studied efforts such as acknowledgment-seeking, the pursuit of recognition from perpetrators and the international community, which experimental and survey research links to improved psychological well-being and greater readiness for compromise.

Critically, the framework treats these beliefs as multidimensional rather than binary. Earlier scholarship often contrasted a single ‘victim mentality’ with its absence, but the review draws on the authors’ own empirical work — including Q-methodology studies across five communities and surveys in Rwanda, Burundi, the Democratic Republic of Congo, Northern Ireland, the Korean diaspora, and elsewhere — showing that people simultaneously hold multiple, sometimes contradictory victimization beliefs. A person may believe their group’s suffering was unique and unmatched while also feeling bound to other victims of history. The same historical memory can underwrite exclusive nationalism in one context and cosmopolitan solidarity in another, depending on which appraisals and coping pathways are activated. This complexity, the authors argue, is precisely what one-dimensional models have missed.

The consequences, or coping outcomes, span both individual and societal levels. At the individual level, chronic threat appraisals and avoidance coping are associated with heightened anxiety, depressive symptoms, and intergenerational transmission of trauma, patterns documented among Holocaust survivors’ descendants, Indigenous adolescents, Ukrainian Holodomor families, and refugee populations. Yet the review also catalogues constructive outcomes: posttraumatic growth after collective violence, altruism born of suffering, and radical hope — a culturally grounded orientation toward a better future even in revolting times. At the societal level, the same belief structures predict support for hostile policies such as population transfer and preemptive strikes on one hand, and for forgiveness, reparations, and joint political decision-making on the other. Recent meta-analytic work on collective victimhood beliefs and conflict-related attitudes confirms that these associations are robust across contexts, though their direction depends on which specific beliefs are measured.

The appraisal–coping lens also clarifies why interventions succeed or fail. Programs that reduce competitive victimhood by recategorizing adversaries into a common victim identity, narratives that frame historical trauma inclusively, moral-exemplar interventions highlighting figures who responded to injustice with principled resistance, and reconciliation radio dramas that encourage historical perspective-taking all work, in this framework’s terms, by shifting primary or secondary appraisals and by modeling approach-oriented coping. Conversely, commemorative practices that reinforce exclusive victimhood — such as memorial days that heighten affective polarization — can entrench threat appraisals even while strengthening ingroup cohesion. The framework thus gives practitioners a diagnostic vocabulary: identify which appraisal is dominant, which coping effort is being rewarded, and which outcome the belief structure is likely to produce.

The authors are careful to note the framework’s boundaries and the research agenda it implies. Much of the evidence remains correlational, drawn from self-report surveys in a limited set of conflict regions, and the field still lacks longitudinal designs tracking how appraisals evolve as violence unfolds or subsides. The review also stresses that coping with collective victimization cannot be reduced to individual adaptation: liberation psychology and decolonial scholarship remind researchers that oppression is structural, and that ‘coping’ in an unjust context may legitimately mean resistance rather than adjustment. Future work, the authors suggest, should examine within-group variation — how gender, generation, class, and intersectional identities shape whose victimization beliefs prevail — and should test the framework’s phases experimentally.

What emerges is a picture both sobering and hopeful. Collective victimization is neither a destiny of endless retaliation nor a guaranteed springboard to solidarity; it is a psychological process whose direction depends on appraisals of threat and agency, on the coping efforts communities can imagine and afford, and on the social and political environments that reward some beliefs while silencing others. By providing a common architecture for a fragmented literature, the review equips researchers, policymakers, and peacebuilders to ask a sharper question than ‘does trauma breed violence?’ — namely, which beliefs about victimhood, under which conditions, lead groups to lash out, and which lead them to reach out.
