Pluralistic ignorance-the systematic misperception of others' attitudes-can entrench suboptimal norms, yet its dynamics remain poorly understood. We develop a mathematical model of the coevolution of actions, private attitudes, and beliefs about others, with societal tightness as a central parameter. Our framework integrates theories of spirals of silence, preference falsification, and cultural mismatch into a single dynamic system capturing the effects of material payoffs, cognitive forces, and social influence. The model shows that pluralistic ignorance can arise from lags between attitude change and belief updating, even without silence or deception. Dynamics unfold faster in loose cultures and slower in tight ones: loose societies display sharp but transient peaks of pluralistic ignorance, while tight societies sustain slower, persistent mismatches. Both can experience cultural evolutionary mismatch but through distinct pathways-internalized norm adherence in loose cultures vs. conformity pressure in tight ones. These mechanisms may help explain global patterns where private support exceeds perceived support, such as climate action, women's rights, and abortion attitudes. Interventions must therefore be culturally tailored: accelerating attitude change through highlighting benefits is effective in loose cultures, whereas lowering expression costs (via anonymity or legal protections) empowers norm entrepreneurs in tight cultures. Our framework identifies policy levers and clarifies when apparent opinion stability conceals underlying shifts, offering insights for democratic societies navigating rapid social change.

Abstract Background : Although Americans increasingly express concern for animals, animal protection remains peripheral in US policy discussions. Aligning animal-related public policy with societal values requires understanding public perspectives on the importance of animal protection as a policy priority, their support for specific policy proposals, and whether pluralistic ignorance may inhibit civic or policy engagement. Methods : A nationally representative sample of US adults (N = 2074) was recruited between July and August 2024 through Prolific using demographic quotas and weighting to align with 2021 US Census distributions. The survey assessed: (1) the importance placed on animal protection relative to other national policy issues; (2) concern about suffering across seven animal categories; (3) perceived importance of government programs to reduce animal suffering; (4) self-reported and factual knowledge of animal protection laws; and (5) support for specific five animal protection laws at the state and federal level (bans on octopus farming, addressing extreme confinement of pigs and chickens, expanding cruelty laws to include wildlife; addressing methods for carnivore hunting; and implementing vessel speed limits for Atlantic right whale conservation). Pluralistic ignorance was evaluated by comparing participants’ own attitudes with their estimates of the public’s attitudes. Results : Participants expressed strong support for prioritizing animal protection in public policy and for specific measures to reduce suffering across a wide range of animal contexts. Concern was highest for animals used in research, in zoos and aquariums, and in entertainment settings, and lowest for invasive wildlife. Respondents reported low levels of perceived knowledge about animal protection laws, despite their high levels of concern for animal suffering and support for animal protection policies at the state and federal level. Evidence of pluralistic ignorance emerged; participants underestimated how supportive other Americans are of policies aimed at reducing animal suffering, both in general and across the five policy case studies. Conclusion : Public support for animal protection is strong across diverse animal issues, yet is widely underestimated by Americans themselves. Communicating the true level of public support may help strengthen animal protection efforts at both state and federal levels. Correcting these misperceptions may reduce social and political barriers, mobilize civic engagement, and help advance policy initiatives aimed at reducing animal suffering.

This study examines the challenges faced by school principals in implementing peer empowerment approaches to address bullying in elementary schools. A Systematic Literature Review (SLR) was conducted in accordance with PRISMA guidelines. Twelve peer-reviewed articles published between 2015 and 2025 were selected from reputable databases, including Scopus, Web of Science, ERIC, Google Scholar, DOAJ, and Garuda. Data were analyzed using thematic analysis to identify recurring psychosocial barriers and leadership-related challenges in the implementation of peer-based anti-bullying programs. The findings reveal four dominant barriers: diffusion of responsibility, students’ fear of becoming subsequent victims, pluralistic ignorance, and observers’ limited knowledge of appropriate intervention strategies. Collectively, these factors contribute to a pattern of collective passivity that weakens students’ capacity to function as active bystanders in bullying prevention. Furthermore, the effectiveness of peer empowerment programs is strongly contingent upon principals’ leadership capacity to cultivate a safe, supportive, and prosocial school climate. This includes the implementation of witness protection mechanisms, the correction of erroneous social norms, the strengthening of moral courage literacy, and the provision of evidence-based intervention training.

Understanding the role of pluralistic ignorance in biodiversity conservation: A research agenda

Classroom norms are important in shaping individual students’ prosocial behavior. Research documents that students often misperceive classroom norms by underestimating their classmates’ prosocial intentions – a phenomenon known as pluralistic ignorance. The current study investigated whether 5 th - and 6 th -grade students in Germany ( N = 234, 10-13 years, 51% female) expressed varying degrees of pluralistic ignorance regarding same- and opposite-gender classmates. Participants listened to a gender-matched scenario about a classmate with learning difficulties seeking inclusion in a group task. They indicated their own inclusive intentions as well as their perception of same-gender and opposite-gender classroom norms. The results supported the main hypothesis that students perceived lower levels of pluralistic ignorance regarding same-gender than opposite-gender classmates. These findings have implications for interventions aimed at correcting students’ norm misperceptions to promote prosocial behavior in classrooms.

Across eight preregistered studies (N = 6,464), we apply an approach informed by social norm theory to investigate perceptions and realities of support for Initiatives for Future Generations (IFGs)-institutions and policies designed to ensure political representation for and protection of future generations. We find widespread bipartisan support for IFGs alongside pluralistic ignorance: Americans vastly underestimate their peers' support. Correcting misperceptions enhances individual support, underscoring the role of social norms in shaping collective action. We also find modest-albeit mixed-evidence that interventions aimed at increasing intergenerational concern can boost support for IFGs without exacerbating pluralistic ignorance. These interventions may serve as a complement to norm-corrective approaches by engaging moral motivations alongside informational strategies. Beyond highlighting the value of correcting norm misperceptions in safeguarding future generations' welfare, we explore motivational explanations for pluralistic ignorance and emphasize that policymakers hold the power to implement IFGs with confidence and the public is behind them.

Most U.S. residents are concerned about and support action on climate change. They also overwhelmingly underestimate the extent to which others are likewise concerned, a phenomenon known as pluralistic ignorance. This is a problem because when individuals perceive that others don’t care, they are less likely to take action themselves. We assessed whether brief exposure to positive thoughts and actions of others might make climate action more normative and increase support for climate policy. Specifically, we exposed people to “Community Voices” (CV), a form of social media designed to promote pro-environmental and pro-social norms. We hypothesized that exposure to CV content (related and unrelated to climate change) would enhance positive climate-related norms and increase climate policy support. We further hypothesized that this shift would be stronger when the content was directly related to climate change and when the content came from participants’ geographic region. Online recruits (N = 969) from national and regional (Northeast Ohio) samples were exposed to either no CV content (control), pro-social CV content (unrelated to climate) or CV content depicting climate action in NE Ohio. Brief exposure to both pro-social and climate action-focused CV content increased both descriptive and prescriptive climate action norms and significantly decreased participants’ psychological distance from climate change. As expected, exposure to climate-focused content increased descriptive norms more than exposure to pro-social content. Pro-social CV content increased policy support. That increase was explained by increased norms and decreased psychological distance. Pro-social CV content significantly increased positive emotions, while climate-focused CV content did not. NE Ohio participants who viewed regional climate-focused content exhibited lower positive emotions and had more difficulty imagining a positive future than those in the national sample. Results suggest that exposure to positive thoughts and actions of others can achieve the critical goals of elevating descriptive norms (thereby reducing pluralistic ignorance) and elevating support for climate policy. However, the psychological impact of exposing people to positive climate-action content is nuanced and complex.

Abstract In this article, I present a potential counterexample to Lackey’s Group Agent Account (GAA) of group beliefs. I argue that cases of pluralistic ignorance pose a problem for Lackey’s GAA because, in such cases, it systematically yields the wrong ascriptions of belief. I then discuss two ways to improve GAA, which I call GAA* and GAA**, that make it immune to the pluralistic ignorance problem. However, I argue that GAA* and GAA** face their own problems that cannot be straightforwardly solved without overfitting the account. I conclude by arguing that pluralistic ignorance is not a minor problem but one that generally affects summative approaches, such as GAA, and provides evidence in support of nonsummative accounts of group beliefs.

ABSTRACT Polarization is considered one of the most serious challenges in democratic countries. While substantial evidence points to exaggerated perceptions of polarization—called false polarization—whether it can persist in the long run remains understudied. This paper develops a social learning model in which each citizen belongs to either of two political groups and holds either of two attitudes on a controversial issue. In each period, two citizens—one from each group—publicly express their opinions on the issue. Citizens havePolitical polarization is considered one of the conformity motives, but their distribution could be misperceived. We show that false polarization may arise as pluralistic ignorance even when the majority shares the same attitude across the two groups. Specifically, when citizens underestimate others' conformity motives, perceived polarization can trigger a self‐reinforcing spiral, leading both groups to appear polarized. Consequently, both groups may continue to publicly express different opinions. Finally, we discuss conditions under which the formation of echo chambers either mitigates or exacerbates false polarization.

For the past decade, the United States spent hundreds of billions of dollars annually on public welfare programs, yet over 30% of eligible individuals do not access benefits distributed through these programs. We propose that a key barrier to program participation is miscalibrated perception of public stigma-individuals' pessimistic impressions of the stigma with which the general public regards welfare-eligible people. First, we examine how people's own attitudes toward a welfare-eligible individual compare to their estimates of parallel attitudes among their peers and among the general public. Study 1 specifically categorizes spontaneous reactions to learning someone is eligible for Supplemental Nutrition Assistance Program (SNAP) benefits: stigma, negativity about help-seeking, pity, envy, willingness to help, happiness, and admiration. Using these seven dimensions, Studies 1 and 2 demonstrate widespread pluralistic ignorance of welfare stigma: Participants believed that they held more positive, and less negative, attitudes toward SNAP-eligible individuals than did their peers or the American public. Studies 3A and 3B utilize established, incentive-compatible designs from the pluralistic ignorance literature to reveal that participants held less negative personal views about the SNAP-eligible population than they believed others did. Study 4 demonstrates the causal potential of perceived public stigma to reduce individuals' intentions to apply for SNAP and to refer the program to peers. Study 5 tests an intervention with a SNAP-eligible population to demonstrate that perceived public stigma can indeed be decreased, although the observed decreases were not sufficient to increase near-term SNAP application or referral tendencies.

ABSTRACT Ambitious climate policies designed to reduce carbon emissions through behaviour change require public consent for their successful implementation, which is dependent on their design and the way they are appraised. The current study, involving a large UK-based sample (n = 2002), brings together research on policy attributes, policy-specific appraisals, and second-order beliefs to examine how they can help explain support for different types of climate policies. The results show that restrictive ‘push’ measures are supported far less than non-coercive ‘pull’ measures; financial measures are less popular than regulatory measures; and measures aimed at changing dietary behaviours are supported less than those aimed at energy and travel behaviours. It further finds that perceived effectiveness, perceived fairness and perceived levels of public policy support (‘second-order beliefs’) follow similar patterns and can explain support for the different climate policies. The study shows that both policy-specific appraisals and second-order beliefs mediate differences in support for the different types of climate policies. Furthermore, while support for the different climate policies is systematically underestimated by 18% and opposition systematically overestimated by 16% on average, the magnitude of pluralistic ignorance is smaller for push measures than for pull measures. The smaller perception gap for the less popular restrictive measures may limit the effectiveness of informational norm interventions in increasing public acceptance of these policies.

ABSTRACT There is a broad consensus in the leading general literature on norms and norm-change that norms are conditional, and based on descriptive and normative expectations. Expectations are a sub-set of beliefs. Hence some primary barriers to norm-change arise from dynamics among beliefs, and between beliefs and preferences. However, the literature has under-examined the distinction between two such barriers, preference falsification and pluralistic ignorance. We clarify the implications of the distinction for two leading conceptual frameworks (due to Kuran and Bicchieri, respectively), and ultimately for explicit models, of norms and norm change. We furthermore explain how, once this clarification is in place, the two models are naturally reconciled by interpreting the concepts of belief – and also preference – that they incorporate as based on attribution from Dennett’s intentional stance.

A wide variety of existing narratives describe how we might address climate change. Which of these approaches is popular among the American public? Do the general public and their elected officials accurately perceive which climate solutions are popular? We assess personal endorsement and perceptions of public support in national representative samples of the U.S. public (N = 1500) and local-level U.S. policymakers (N = 500). Proactive narratives, like ones advocating for both personal behavior and policy action, are widely endorsed, but both the public and policymakers greatly underestimate their popularity (a case of pluralistic ignorance), especially for narratives calling for systemic change. Greater endorsement of these narratives corresponded to greater willingness to take personal and political actions and support climate policy. We also find experimental exposure to some climate narratives (N = 2060) may increase participants’ behavioral intentions and policy support, suggesting which narratives are spread in popular media is important to help address climate change.

Achieving sustainable and long-lasting ecological conservation incentives necessitates incorporating the intrinsic motivations of farmers into policy design frameworks. Currently, existing payments for ecosystem services (PES) projects overly focus on monetary incentives, particularly in Chinese projects that primarily revolve around payment standards and place little emphasis on payment design. In this study, a multi-factor mixed field experiment was conducted in Napo County, Southwest China, based on the three dimensions of the bystander effect: diffusion of responsibility (population size), evaluation apprehension (disclosure or non-disclosure), and pluralistic ignorance (emergency level). The key factors that motivate farmers’ sense of responsibility for ecological protection were analysed, showing that: (1) a high emergency level plays a significant role in stimulating farmers’ awareness for ecological protection; (2) the influence of disclosure is significant in smaller areas but weakens with increasing area; (3) faced with the long-term, collective responsibility event of ecological protection, population size does not trigger the bystander effect in ecological protection; (4) most interestingly, patriotism has extreme application potential in ecological protection. This study explores the non-economic factors that encourage ecological stewardship among farmers and applies new approaches to field experiments in payments for ecosystem services, with a specific focus on developing countries.

Pluralistic ignorance of lookism among the Chinese youth: focusing on social media appearance content usage, appearance conversations, and eating disorders

With the rise of social media, corporate employment image on social media platforms critically impacts the employment situation. Recently, there have been evident differences in the corporate employment image of different industries on Chinese social media platforms. Pluralistic ignorance widely exists in online discussions of different themes and may also influence people’s opinion of corporate employment image. However, little is known about the effect manner and degree of pluralistic ignorance in discussing different corporate employment images. This paper integrates the latest opinion dynamics model, expressed-private-opinions (EPO), and deep learning through an EPO-based SINN and applies the proposed model to a real-world dataset from Chinese social media. We focus on five important industries in China as research objects and constructed datasets containing 110,763 pieces of text data and then compare the performance of the proposed method with baseline methods on the datasets. EPO-based SINN gets the F1-scores of 0.801, 0.781, 0.744, 0.751 and 0.795 on five industries’ datasets and outperforms baseline methods. The prediction results confirm the existence of pluralistic ignorance, and the optimized resilience parameter in EPO-based SINN reveals the different scales of pluralistic ignorance in the five themes. Furthermore, our quantitative analysis shows that the proportion and polar distribution of zealots in social networks positively impact the scale of pluralistic ignorance. Our work reveals the mechanisms between pluralistic ignorance and corporate employment image and infers the main driver making a difference in the scale of pluralistic ignorance across discussions of different industries.

Most people believe in human-caused climate change, yet this public consensus can be collectively underestimated (pluralistic ignorance). Across two studies using primary data (n = 3,653 adult participants; 11 countries) and secondary data (ns = 60,230 and 22,496 adult participants; 55 countries), we tested (a) the generalizability of pluralistic ignorance about climate-change beliefs, (b) the effects of a public-consensus intervention on climate action, and (c) the possibility that cultural tightness-looseness might serve as a country-level predictor of pluralistic ignorance. In Study 1, people across 11 countries underestimated the prevalence of proclimate views by at least 7.5% in Indonesia (90% credible interval, or CrI = [5.0, 10.1]), and up to 20.8% in Brazil (90% CrI = [18.2, 23.4]. Providing information about the actual public consensus on climate change was largely ineffective, except for a slight increase in willingness to express one’s proclimate opinion, δ = 0.05 (90% CrI = [−0.02, 0.11]). In Study 2, pluralistic ignorance about willingness to contribute financially to fight climate change was slightly more pronounced in looser than tighter cultures, highlighting the particular need for pluralistic-ignorance research in these countries.

The Impact of Pluralistic Ignorance on Knowledge-Sharing Behaviour in Virtual Teams

When experiencing depressive symptoms, many people delay or avoid seeking professional help. We investigate whether misperceptions of other’s willingness to seek help can be a potential barrier for help-seeking by examining pluralistic ignorance (i.e., when members of a group mistakenly believe that others’ cognitions or behaviors differ systematically from their own) in men and women’s perceptions of others’ help-seeking willingness. Experiment 1 (N = 2042) demonstrated that both men and women underestimate men’s willingness to seek formal help but showed no evidence of pluralistic ignorance in women’s perceptions of “most women’s” help-seeking. For both men and women, self-rated willingness to seek help was strongly associated with the perception that other men/women would seek help. Based on these results, we proposed that a lower willingness to disclose help-seeking for depressive symptoms among men could be a source of misperceptions of men’s help-seeking willingness. Experiment 2 (N = 1528) showed that men were less willing than women to disclose help-seeking for depression to friends and colleagues, which could contribute to misperceptions of men’s help-seeking willingness. We argue that pluralistic ignorance can be a barrier for men’s mental health help-seeking and discuss implications for interventions to increase the number of men who seek help when experiencing depressive symptoms.

Abstract: Previous research shows clear evidence of pluralistic ignorance regarding prejudice: People believe that others are more prejudiced than they are. However, it is not clear whether these inferences pertain to automatic or controlled prejudice. In this study, participants completed automatic and controlled attitudinal measures regarding several groups, and they estimated how other people would respond to those measures. Participants underestimated how positive other people’s attitudes are, particularly for automatic responses. Still, participants believed that other people can correct and revise these automatic responses and produce more positive controlled responses. However, the presumed controlled responses of others are more negative than participants’ own automatic responses.
