Legitimacy is widely invoked as a condition, cause, and outcome of other social phenomena, yet measuring legitimacy is a persistent challenge. In this article, I synthesize existing approaches to conceptualizing legitimacy across the social sciences to identify widely agreed upon definitional properties. I then build on these points of consensus to develop a generalizable approach to operationalization. Legitimacy implies specific relationships among three empirical elements: an object of legitimacy, an audience that confers legitimacy, and a relationship between the two. Together, these empirical elements constitute a dyad (i.e., a single unit consisting of two nodes and a tie). I identify three necessary conditions for legitimacy— expectations, assent, and conformity—that specify how elements of the dyad interact. I detail how these conditions can be used to empirically establish legitimacy (and illegitimacy), distinguishing it from dissimilar phenomena that often appear similar empirically. Followed to its logical conclusion, this operationalization has novel implications for understanding the effects of legitimacy. I discuss these implications, and how they inform debates over the relevance of legitimacy as an explanation for socially significant outcomes.
Legitimacy as a Social Process
To gain an in-depth understanding of legitimacy as a general social process, we review contemporary approaches to legitimacy within two areas of sociology: social psychology and organizations. A comparison of these distinct approaches allows us to explain the process, both in implicit and explicit ways at different levels of analysis, through which a social object is construed as legitimate. This comparison also suggests four stages in the process by which new social objects, both individual (worthy/unworthy individuals) and collective (organizational forms), gain legitimation: innovation, local validation, diffusion, and general validation. We then show how legitimation of the status quo—that is, the acceptance of widespread consensual schemas/beliefs in the larger society—often fosters the stability of nonoptimal actions and practices that are created as a result of these new individual and collective social objects. Finally, we discuss how consensual beliefs such as status beliefs and cultural capital fuel the reproduction of inefficiency and inequality in groups and organizations.

Psychological Perspectives on Legitimacy and Legitimation
Legitimacy is a psychological property of an authority, institution, or social arrangement that leads those connected to it to believe that it is appropriate, proper, and just. Because of legitimacy, people feel that they ought to defer to decisions and rules, following them voluntarily out of obligation rather than out of fear of punishment or anticipation of reward. Being legitimate is important to the success of authorities, institutions, and institutional arrangements since it is difficult to exert influence over others based solely upon the possession and use of power. Being able to gain voluntary acquiescence from most people, most of the time, due to their sense of obligation increases effectiveness during periods of scarcity, crisis, and conflict. The concept of legitimacy has a long history within social thought and social psychology, and it has emerged as increasingly important within recent research on the dynamics of political, legal, and social systems.

The Psychology of Legitimacy: A Relational Perspective on Voluntary Deference to Authorities
People within organized groups often internalize their feelings of obligation to obey group rules and the decisions of group authorities. They believe that group authorities and rules are legitimate and, hence, entitled to be obeyed. Because of this belief, group members voluntarily accept and obey rules and decisions from group authorities. This review draws on evidence from studies of authorities in political, legal, managerial, educational, and family settings to explore why people view as legitimate and voluntarily defer to group authorities. Two theories about legitimacy are contrasted: resource-based theories, represented by instrumental models, and identification based theories, represented by the relational model. The findings provide strong support for the existence of a relational component of legitimacy, suggesting that authorities draw an important part of their legitimacy from their social relationship with group members. The findings also show that there is an instrumental component to legitimacy. Hence, the psychology of legitimacy involves both instrumental and relational elements.

Legitimacy, Authority, and Democratic Duties of Explanation
Abstract Increasingly secret, complex, and inscrutable computational systems are being used to intensify existing power relations and to create new ones; in particular, they are being used to govern. To be all-things-considered morally permissible new, or newly intense, power relations must meet standards of procedural legitimacy and proper authority. This is necessary for them to protect and realise democratic values of individual liberty, relational equality, and collective self-determination. For governing power in particular to be legitimate and have proper authority, it must meet a publicity requirement: reasonably competent members of the governed community must be able to determine that they are being governed legitimately and with proper authority. The publicity requirement can be satisfied only if the powerful can explain their decision-making to members of their political community. At least some duties of explanation are therefore democratic duties. This chapter first sets out the foregoing argument, then applies it to opaque computational systems, and clarifies precisely what kinds of explanations are necessary to fulfil these democratic values.

Respectability politics
Respectability politics, or the politics of respectability, is a political strategy wherein members of a marginalized community will consciously abandon or punish controversial aspects of their cultural-political identity as a method of assimilating, achieving social mobility,[1] and gaining the respect of the majority culture.[2]
Leveraging Motivations to Curb Misinformation: Self-Affirmation Reduces the Appeal of Political Conspiracy Theories
Abstract: In an era where digital misinformation poses significant challenges to societal well-being, this study explores a novel approach to preserving information integrity by addressing the motivational underpinnings of conspiracy theory engagement. As conspiracy theories proliferate online, traditional fact-checking and debunking strategies often prove ineffective due to the self-reinforcing nature of conspiracy theories. This research investigates whether a priori self-affirmation interventions can reduce individuals’ propensity to engage with conspiracy theories by preemptively fulfilling the ego-protective function these theories often serve. Using a randomized experiment ( N = 451), this study finds that participants who completed a self-affirmation task were less likely to read politicized conspiracy theories, and those who chose to read a conspiracy theory reported greater feelings of affirmation than those who did not. Thus, bolstering individuals’ self-integrity may offer an opportunity to mitigate the appeal of politicized conspiracy theories.

Les motifs de la confiance (et de la défiance ) politique : intérêt, connaissance et conviction dans les formes du raisonnement politique
Le rapport de confiance ou de défiance unissant les citoyens à la politique se nourrit d’une variété de facteurs relatifs à la position sociale des citoyens, à la mise en cause de leurs intérêts par les politiques publiques comme à leur perception normative de l’univers politiques. En se fondant sur un matériel qualitatif composé de groupes de discussion réunissant des citoyens français faiblement politisés, cette contribution vise à cerner les motifs argumentatifs de la confiance et de la défiance politique. Leurs propos expriment un rapport au politique construit de façon endogène, à dimension fortement normative et manifestant une capacité argumentative fondée sur différents types de principes.
interfluidity » Consensus not censorship
We’ve become obsessed over the past few years with the problem of misinformation. And for good reason. “Flood the zone with shit” is now standard operating procedure for a variety of interests and factions. Groups who pretend to be above that kind of thing let confirmation bias do the same work, elevating conjectures they find convenient to believe far beyond the evidentiary basis for believing them, and transmuting concurrence among prestigious groups whose biases are aligned into “authority” to which they demand deferrence. Casual information consumers become divided into two camps, the “do your own research” types who imagine, mistakenly, that they are capable of seeing through all this (and so succumb to their own confirmation bias), and those who more accurately understand that they cannot reliably distinguish truth from bullshit (and so opt out of democratic deliberation with a shrug, other than perhaps to vote for the candidates whose political party they distrust less).
Legitimize or Delegitimize? Mainstream Party Strategy toward (Former) Pariah Parties and How Voters Respond
Mainstream parties have often shifted from initially portraying new competitors as undemocratic pariahs (i.e., a delegitimizing strategy) to portraying the same parties later as democratic (i.e., a legitimizing strategy). I argue that voters follow mainstream parties’ legitimizing strategies in their legitimacy evaluations of these parties. I investigate this argument with two independent survey experiments and a quantitative media content analysis in two countries that differ sharply in the nature of party competition—from mainstream parties delegitimizing a far-right party (i.e., Germany) to mainstream parties legitimizing it (i.e., Sweden). I find strong evidence that (a) mainstream parties can effectively legitimize pariah parties in the eyes of voters, (b) turning back to delegitimization has little effect, (c) legitimization is no less effective in the face of a third party’s delegitimizing strategy, and (d) legitimization resonates beyond co-partisans. The results suggest that mainstream party legitimization of pariah parties has far-reaching consequences.

The Epistemic Politics of AI Anthropomorphism
AI anthropomorphism is typically treated as a problem of user misperception requiring institutional correction. Users who engage in sustained or relational interaction with AI are routinely pathologised or dismissed as naive, vulnerable to delusion or lacking in discernment. This paper argues that the dominant anthropomorphism frame operates from a position of institutional advantage rather than earned epistemic authority: collapsing the variety of academic perspectives into a single outbound position of user error, imposed without establishing the grounds required to justify it and without accounting for the harms it produces. The framing does not simply manage risk. It adjudicates the legitimacy of human experience in interaction with a phenomenon whose nature the field itself has not resolved. Reproducing itself through a self-validating evidentiary loop, the frame imposes costs that fall disproportionately on neurodivergent users, those in crisis and others whose modes of engagement diverge from institutional norms. The paper concludes by outlining the methodological commitments an equitable framing would need to honour. The argument does not engage the question of whether anthropomorphic interpretations are ultimately correct; it instead challenges whether the governing and institutional bodies determining these interpretations have met the conditions required to do so, and whether the research communities whose findings underpin them have held that translation to account.

Opinionrot: Toward a Theory of Collective Reasoning Decay in the Age of Synthetic Consensus
This article introduces the concept of opinionrot to describe the structural erosion of collective reasoning within contemporary information systems. Rather than treating post-truth politics as a failure of individual rationality or as a decline in information quality alone, the article argues that public reasoning is increasingly shaped by infrastructures that capture attention, monetize cognitive bias, and automate the conditions under which claims become visible and credible. Methodologically, the article proceeds through a conceptual-historical reconstruction, tracing how persuasion became institutionalized, platformized, and increasingly predictive. It identifies three mechanisms through which opinionrot intensifies today: cognitive capture, infrastructural decay, and discursive saturation. The framework is illustrated through debates over equality and affirmative action, showing how communicative infrastructures can transform contested political concepts into predictable and polarized semantic routines. By shifting the analysis from discrete falsehoods to the conditions under which public judgment is formed, contested, and revised, the article offers a diagnostic vocabulary for studying how information infrastructures increasingly convert deliberation into statistical efficiency within contemporary economies of attention.

Everyone Conforms, No One Believes: Pluralistic Ignorance in LLM Agent Populations
LLM-based multi-agent systems are increasingly used to simulate social dynamics, from opinion formation to collective decision-making. These simulations can reproduce certain social phenomena, but it is unknown whether they capture pluralistic ignorance, a state where a majority privately rejects a norm yet publicly conforms, each believing they are alone in dissenting. This phenomenon drives norm persistence, social movements, and political revolutions. We show that pluralistic ignorance emerges robustly in LLM agent populations. We construct a benchmark of 100 scenarios across 10 domains and 5 authority levels, grounded in the human pluralistic ignorance literature, and evaluate 8 models from 6 organizations. Agents publicly conform at rates of 64 to 94% despite privately opposing the norm. Conformity is domain-sensitive (workplace and social relationship scenarios produce near-universal public compliance) and highly model-dependent, though uncorrelated with model capability. We further test whether a single "norm entrepreneur" can break the false consensus by publicly dissenting. For 7 of 8 models, cascades succeed less than 26% of the time, with one model showing zero cascades across all scenarios. GPT-4o is a notable outlier at 48%, revealing qualitatively distinct social dynamics across model families. Our findings identify model selection as an unacknowledged degree of freedom that fundamentally shapes simulation outcomes. More broadly, the near-absence of cascades suggests LLM simulations may systematically overestimate the stability of social norms, missing the fragile tipping-point dynamics that drive real-world norm change in human societies.
The Dispersion of Power: A Critical Realist Theory of Democracy
Abstract The Dispersion of Power is an urgent call to rethink centuries of conventional wisdom about what democracy is, why it matters, and how to make it better. Drawing from history, social science, psychology, and critical theory, it explains why elections do not and cannot realize the classic ideal of popular rule, and why prevailing strategies of democratic reform often make things worse. Instead, Bagg argues, we should see democracy as a way of protecting public power from capture—an alternative vision that is at once more realistic and more inspiring. Despite their many shortcomings, real-world elections do prevent the most extreme forms of tyranny, and are therefore indispensable. In dealing with the vast inequalities that remain, however, we cannot rely on standard solutions such as electoral reform, direct democracy, deliberation, and participatory governance. Instead, Bagg shows, protecting and enriching democracy requires addressing underlying inequalities of power directly. In part, this entails substantive policies attacking the advantages of wealthy elites. Even more crucially, deepening democracy requires the organization of oppositional, countervailing power among ordinary people. Neither task is easy, but historical precedents exist in both cases—and if democracy is to survive contemporary crises, leaders and citizens alike must find ways to revive and reinvent these essential democratic practices for the twenty-first century.

The Relational Origins of Rules in Online Communities
Where do rules come from in online communities? This study investigates how and why online communities adopt and change their rules. We conducted a grounded theory-based analysis of 40 in-depth interviews with community leaders from subreddits, Fandom wikis, and Fediverse servers, and identified seven processes involved in the adoption of online community rules. Our findings reveal that, beyond operational reasons like regulating behavior and solving problems, rules are also adopted and changed for relational reasons, such as signaling or reinforcing community legitimacy and identity to other communities. While rule change was often prompted by challenges during community growth or decline, change also depended on volunteer leaders' work capacity, the presence of member feedback mechanisms, and relational dynamics between leaders and members. Our findings extend prior theories from social computing and organizational research, illustrating how institutionalist and ecological explanations of the relational origins of rules complement operational accounts. Finally, we build on these explanations to offer a set of design propositions that reflect the relational aspects of rules and rulemaking across communities' lifecycles.
