  Recent decades have seen a surge of research revealing the core, early emerging psychological building blocks for navigating human societies. Yet, how such core motives operate across life, undergirding political ideology, remains unknown. Here we use the same kind of minimal, abstract group stimuli across the lifespan to show that gendered preferences for majority groups manifest among preschoolers and adults alike (but not among preverbal infants) and that they motivate support for sustaining intergroup hierarchies (for example, ethnic persecution, militarism and social welfare opposition) among adults. Preschool (N = 317) boys, but not girls, preferred majority rather than minority members, whereas infants (N = 180) chose randomly between the two. Among adults (N = 3,467), males also liked the majority more than females, and these coalitional preferences correlated robustly with political ideology. These results indicate that gendered motives for intergroup formidability are rooted in earliest childhood once children begin navigating peer relationships independently.

  Ownership is a pervasive feature of human social life, yet its developmental origins remain unknown. One influential proposal is that human ownership psychology is built on an early-developing and evolutionary ancient sensitivity to first possession: Across species, conflicts over resources are often settled in favor of whoever held a resource first. Among humans, individuals who take what others already possess are often devalued as cooperative partners. Here, we focused on the inferences and preferences infants and toddlers form based on first possession. Across six laboratory experiments (N = 227), we found positive Bayesian evidence that 10–18-month-old infants and young toddlers do not expect intruders will defer to first possessors in territorial conflict, and that 10–13-month-old infants do not prefer prior possessors over those who take (or attempt to take) possessions from others by force. In contrast, we found that infants do expect that larger, more physically formidable agents will prevail in territorial conflict, using identical methods. Hence, prior possession alone is not sufficient for shaping infants' expectations and evaluations in dyadic conflict, though physical formidability is.

  Society is characterized by negotiation of group interests, often favoring stronger majority groups. Preverbal infants expect members of larger coalitions to prevail in concrete conflicts, but it remains unknown if infants parse the social world by ascribing general default coalitional formidability motives to others, even in the absence of intergroup conflict. Here we show that 9–13-month-old Norwegian infants (N = 168, 83 girls, ethnicity unrecorded, data collected 2018–2025) expected an agent to approach the larger of two separate, coordinated groups (Cohen's g = .15-.17). So did North American and Norwegian adults across explicit (N = 1,704, d > .11) and implicit measures (N = 33, Cohen's g = .23). Humans infer third-party group formidability motives across ontogeny.

  Social hierarchies ultimately concern resource possession, yet psychological processes for regulating resource-related tensions remain underexplored. We examine how support for intergroup equality (egalitarianism) relates to explicit attitudes toward, and mental images of, the resource poor. In Study 1 ( N = 625), egalitarians report more favorable attitudes toward the resource poor than anti-egalitarians. However, using the reverse correlation paradigm, both groups generate similarly negative mental images of this group, as shown by pixel luminance comparisons (Study 1) and evaluated by independent raters of person-perceptual (Study 2, N = 394) and coalitional traits (Study 3, N = 348). While ideology did not shape image generation, it did influence image evaluation: egalitarian raters showed less polarization between resource-poor and resource-rich faces than anti-egalitarian raters. These findings suggest that despite ideological differences in explicit attitudes (divergence), egalitarians, and anti-egalitarians share similarly negative mental representations (convergence) of the resource poor, highlighting a nuanced interplay between social perception and hierarchy regulation.

  Men hold more power compared to women, a phenomenon that is globally evident and widely documented. Preverbal infants mentally represent social dominance, and by the age of 18 months can distinguish male and female voices and associate them with faces of the corresponding gender. Here, we investigated whether 18- to 24- month-old toddlers (N=48) expected male-voiced agents to prevail over female-voiced ones in a right-of-way conflict. Using a violation-of-expectation paradigm, we found that toddlers looked longest when female-voiced characters prevailed in dominance conflicts, suggesting they expected that male-voiced agents would prevail instead. Acoustic features of male voices that perceptually suggest greater formidability/physical size (i.e., lower fundamental frequency) may account for this effect. Alternatively, vocal indicators of speaker sex might trigger very early conceptualizations about gender and dominance.

  Navigating social affiliation adaptively is a critical task of human life. If parsing the social world into affiliative groups forms a core, generative mechanism of the evolved human mind, even infants may differentiate between minimal depictions of inclusion and exclusion. Furthermore, whether groups include or exclude others may cue their individual value as social partners. If so, infants may expect third-party observers to continue avoiding those others exclude and prefer those they include, further perpetuating discrimination of the already marginalized. Here, we show that 10-18 m.o. infants (n=96) look longer when a neutral observer approaches a novel agent whom an abstract group previously excluded, rather than included, in an animated violation-of-expectation paradigm. We found no effect of participant age. Movements were identical across scenarios, differing only in a delay between the excluded agent and the group. These findings indicate that even infants infer that observed exclusion versus inclusion will generalize to other interactions with new social partners.

  Normative concerns for ownership fundamentally regulate social interaction regarding resources in humans, but little is known about origins of ownership inferences and evaluations tin earliest human development. Here, we ask if normative evaluations of ownership respect are rooted in an early-developing protomoral dispreference for those who violate ownership. Across two studies (N = 66) infants saw puppet shows where an owner was approached by a non-owner who attempted to take the owner's resource. Infants were subsequently allowed to choose between the two puppets. We controlled for the dominance implications of the outcomes of resource competition by systematically varying whether the non-owner or owner prevailed in attaining the resource. Both studies yielded clear Bayesian evidence that infants did not preferentially reach towards either the owner or ownership violator. These results suggest that infants do not hold strong negative evaluations of those who violate ownership.

  Objective: Political attitudes are predicted by the key ideological variables of right-wing authoritarianism (RWA) and social dominance orientation (SDO), as well as some of the Big Five personality traits. Past research indicates that personality and ideological traits are correlated for genetic reasons. A question that has yet to be tested concerns whether the genetic variation underlying the ideological traits of RWA and SDO has distinct contributions to political attitudes, or if genetic variation in political attitudes is subsumed under the genetic variation underlying standard Big Five personality traits. Method: We use data from a sample of 1987 Norwegian twins to assess the genetic and environmental relationships between the Big Five personality traits, RWA, SDO, and their separate contributions to political policy attitudes. Results: RWA and SDO exhibit very high genetic correlation (r = 0.78) with each other and some genetic overlap with the personality traits of openness and agreeableness. Importantly, they share a larger genetic substrate with political attitudes (e.g., deporting an ethnic minority) than do Big Five personality traits, a relationship that persists even when controlling for the genetic foundations underlying personality traits. Conclusion: Our results suggest that the genetic foundations of ideological traits and political attitudes are largely non-overlapping with the genetic foundations of Big Five personality traits.

  Research has shown that infants represent legitimate leadership and predict continued obedience to authority, but which cues they use to do so remains unknown. Across eight pre-registered experiments varying the cue provided, we tested if Norwegian 21-month-olds (N=128) expected three protagonists to obey a character even in her absence. We assessed whether bowing for the character, receiving a tribute from or conferring a benefit to the protagonists, imposing a cost on them (forcefully taking a resource or hitting them), or relative physical size were used as cues to generate the expectation of continued obedience that marks legitimate leadership. Whereas bowing sufficed in generating such an expectation, we found positive Bayesian evidence that all the other cues did not. Norwegian infants unlikely have witnessed bowing in their everyday life. Hence, bowing/prostration as cue for continued obedience may form part of an early-developing capacity to represent leadership built by evolution.

  The attachment and caregiving domains maintain proximity and care-giving behavior between parents and offspring, in a way that has been argued to shape people’s mental models of how relationships work, resulting in secure, anxious or avoidant interpersonal styles in adulthood. Several theorists have suggested that the attachment system is closely connected to orientations and behaviors in social and political domains, which should be grounded in the same set of familial experiences as are the different attachment styles. We use a sample of Norwegian twins (N = 1987) to assess the genetic and environmental relationship between attachment, trust, altruism, right-wing authoritarianism (RWA), and social dominance orientation (SDO). Results indicate no shared environmental overlap between attachment and ideology, nor even between the attachment styles or between the ideological traits, challenging conventional wisdom in developmental, social, and political psychology. Rather, evidence supports two functionally distinct systems, one for navigating intimate relationships (attachment) and one for navigating social hierarchies (RWA/SDO), with genetic overlap between traits within each system, and two distinct genetic linkages to trust and altruism. This is counter-posed to theoretical perspectives that link attachment, ideology, and interpersonal orientations through early relational experiences.

  Cooperation is fundamentally moderated by the form of relationship between the actors involved, as is normative resource distribution. We argue that possessions are likely treated differently across different types of cooperative relationships. Whereas Boyer's computational model might in principle account for this, the theory would benefit from a specification of how different cooperative contexts can shape the representation of ownership.

  Abstract Injustice typically involves some people benefitting at the expense of others. An opportunist might then be selectively motivated to amend only the injustice that is harmful to them, while someone more principled would respond consistently regardless of whether they stand to gain or lose. Here, we disentangle such principled and opportunistic motives towards injustice. With a sample of 312 monozygotic- and 298 dizygotic twin pairs (N = 1220), we measured people’s propensity to perceive injustice as victims, observers, beneficiaries, and perpetrators of injustice, using the Justice Sensitivity scale. With a biometric approach to factor analysis, that provides increased stringency in inferring latent psychological traits, we find evidence for two substantially heritable factors explaining correlations between Justice Sensitivity facets. We interpret these factors as principled justice sensitivity (h 2  = 0.45) leading to increased sensitivity to injustices of all categories, and opportunistic justice sensitivity (h 2  = 0.69) associated with increased sensitivity to being a victim and a decreased propensity to see oneself as a perpetrator. These novel latent constructs share genetic substrate with psychological characteristics that sustain broad coordination strategies that capture the dynamic tension between honest cooperation versus dominance and defection, namely altruism, interpersonal trust, agreeableness, Social Dominance Orientation and opposition to immigration and foreign aid.

  Theories of cultural evolution posit that cues of competence-based prestige, rather than formidability-based dominance, should guide culturally transmitted learning, but recent work suggested that French and Kaqchikel Guatamalan preschoolers place their epistemic trust in dominant others. In contrast, this study shows that 249 three- to six-year-olds (116 girls, tested between 2016 and 2018 across metropolitan locations with varying ethnic composition and socioeconomic status) randomly endorsed the word-labels of dominant and subordinate agents in the egalitarian culture of Norway, using stimuli which solicit dominance inferences among infants and manipulating anonymity across studies to control for egalitarian desirability bias. A meta-analysis estimated that 48% endorsed the dominant's testimony. This demonstrates that the tendency to endorse the epistemic claims of dominant individuals does not emerge reliably in early childhood.

  Majority-group members often hold negative attitudes toward minority-group members who identify with both the majority and their minority group. Integrating perspectives from social identity theory and acculturation research with a coalitional psychology framework, we show that an underlying mechanism for such bias is the perception that dual identifiers are disloyal to the majority group. In Study 1, majority-group participants in the U.S. questioned the loyalty of a dually identified Arab immigrant more than one who identified solely with the (American) majority group, especially under intergroup threat, which in turn predicted less favorable feelings toward the immigrant. Study 2 conceptually replicated the effect of the identity manipulation and the mediating influence of perceived loyalty on judgments about an immigrant being allowed to enlist in the U.S. military. Study 3, partially replicated the findings in Poland, focusing on Russian immigrants as targets. In Study 4, which independently manipulated both the identity expressed by immigrants and their loyalty, a dually identified immigrant whose loyalty to the majority group was portrayed as high was not judged as less qualified than an immigrant who identified only with the majority group for jobs with the potential to inflict damage on the majority group. Study 5, replicated and extended the previous studies in the context of fans of allied or rival soccer teams in Germany, revealing the moderating role of existing group relations on the hypothesized loyalty processes. In summary, coalitionally driven perceptions of (dis)loyalty appear to undergird bias toward minority-group members who hold dual identifications.

  A foundational question in the social sciences concerns the interplay of underlying causes in the formation of people’s political beliefs and prejudices. What role, if any, do genes, environmental influences, or personality dispositions play? Social dominance orientation (SDO), an influential index of people’s general attitudes toward intergroup hierarchy, correlates robustly with political beliefs. SDO consists of the subdimensions SDO-dominance (SDO-D), which is the desire people have for some groups to be actively oppressed by others, and SDO-egalitarianism (SDO-E), a preference for intergroup inequality. Using a twin design (n = 1,987), we investigate whether the desire for intergroup dominance and inequality makes up a genetically grounded behavioral syndrome. Specifically, we investigate the heritability of SDO, in addition to whether it genetically correlates with support for political policies concerning the distribution of power and resources to different social groups. In addition to moderate heritability estimates for SDO-D and SDO-E (37% and 24%, respectively), we find that the genetic correlation between these subdimensions and political attitudes was overall high (mean genetic correlation 0.51), while the environmental correlation was very low (mean environmental correlation 0.08). This suggests that the relationship between political attitudes and SDO-D and SDO-E is grounded in common genetics, such that the desire for (versus opposition to) intergroup inequality and support for political attitudes that serve to enhance (versus attenuate) societal disparities form convergent strategies for navigating group-based dominance hierarchies.

  From the 2016 US presidential election and into 2019, we demonstrate that a visceral feeling of oneness (that is, psychological fusion) with a political leader can fuel partisans’ willingness to actively participate in political violence. In studies 1 and 2, fusion with Donald Trump predicted Republicans’ willingness to violently persecute Muslims (over and above other established predictors). In study 3, relative deprivation increased fusion with Trump and, subsequently, willingness to violently challenge election results. In study 4, fusion with Trump increased after his election and predicted immigrant persecution over time. Further revealing its independent effects, this fusion with Trump predicted a willingness to persecute Iranians (independent of identification with him, study 5); a willingness to persecute immigrants (study 6); and a willingness to personally protect the US border from an immigrant caravan (study 7), even over and above fusion with the group of Trump’s followers. These findings echo past political movements and suggest critical future research.

  Although the protracted Israeli-Palestinian conflict is rooted in contesting ethno-national narratives, it is often also framed and perceived in religious terms. While all 3 groups who consider the region a holy land, namely Jews, Muslims and Christians, have theological roots in common, the potential of emphasizing such commonalities among more than 2 groups and—most importantly—whether acknowledging such shared Abrahamic lineage generally may be an asset for actual peacemaking in the region remains unknown. Focusing on the Israeli-Palestinian conflict, we aimed to fill this gap by using diverse groups and contexts. In Study 1, American Jews acknowledging their shared Abrahamic lineage with Muslims were more supportive of aid to, and peacemaking with, Palestinians. Next, we broadened this categorization to also include Christians. In Study 2, the more American Jews acknowledged this extended categorization including all 3 groups, the less biased they were toward Muslims and Christians and the more they supported political and territorial conflict solutions. We then took the paradigm to the Middle East. In Study 3, Israeli Jews acknowledging the Abrahamic category showed less bias toward Muslims and Christians and were more supportive of peacemaking, intergroup contact and the two-state solution. Finally, in Study 4, Palestinian-Muslims living in the Palestinian Territories who acknowledged this shared religious lineage showed less bias toward Jews, yet more bias toward Christians. In all studies, findings held when controlling for political orientation or social dominance orientation. Implications for using religious and Abrahamic categorizations for conflict resolution and intergroup relations are discussed.

  This research demonstrates a common psychology of outgroup hostility driven by perceived intergroup threat among three groups and seven cultural contexts: non‐Muslim Westerners, Muslims in Western societies, and Muslims in the Middle East. In Study 1, symbolic, but not realistic and terroristic threats, predicted non‐Muslim Norwegians' intentions to join anti‐Islamic movements. In Study 2, symbolic and realistic, but not terroristic threat, predicted non‐Muslim Americans' willingness to persecute Muslims. In Studies 3 and 4, symbolic threat predicted support and behavioral intentions against the West among Swedish and Turkish Muslims. Finally, in Study 5, a comparison demonstrated that symbolic and realistic threats had the same effects on violent intentions among non‐Muslim and Muslim Danes, and Muslims in Afghanistan. Meta‐analysis showed that symbolic threat was most strongly associated with intergroup hostility. Across studies, participants with high religious group identification experienced higher levels of threat. Implications for intergroup research and prejudice reduction are discussed.

  Physical cues influence social judgments of others. For example, shorter individuals are evaluated less positively than taller individuals. Here, we demonstrate that height also impacts one of the most consequential intergroup judgments—attributions of humanity—and explore whether this effect is modulated by the tendency to value hierarchy maintenance. In Study 1, the shorter participants perceived a range of out-groups to be, the more they dehumanized them, and this tended to be particularly pronounced among those scoring high on social dominance orientation (SDO). In Study 2, participants dehumanized an out-group more when they were led to believe that it was relatively short. Finally, Study 3 applied a reverse correlation approach, demonstrating that participants in general, and especially those scoring high on SDO, represented shorter groups in ways less consistent with full humanity than they represented taller groups. Together, this research demonstrates that basic physical height cues shape the perceived humanity of out-groups.

  Religious fundamentalism is associated with Christian–Islamic conflicts globally, but the psychological reasons remain unexplored. Here, we show that fundamentalism is detrimental to interreligious relations because it makes Christians and Muslims alike reject common theological grounds and Abrahamic origins. Specifically, Study 1 demonstrated that such dual Abrahamic categories mediated the negative effects of fundamentalism on real monetary donations to outgroup children desperately in need (i.e., Save the Children Syria) among Christians but not Atheists. Of importance, this was the case only to the degree that Syrian children were perceived as Muslims and, hence, as part of an Abrahamic outgroup. Using a double-randomized experimental design, Study 2 demonstrated the causal effects of religious fundamentalism on Abrahamic categorization and of Abrahamic categorization on mutual resource distribution bias among Muslims and Christians. Together, these studies suggest that religious fundamentalism fuels interreligious conflicts because it crucially impacts basic categorization processes, with subsequent negative effects on intergroup relations.

  The distribution of scarce resources, priority rights, help, and care are central dilemmas of human life. Seminal proposals hold that reciprocity is key for the evolution of cooperation among non-kin, and norms of reciprocity permeate human society. Yet, it remains unknown if human infants are prepared to represent and respond appropriately to direct reciprocity prior to extensive socialization. Here we show that preverbal infants (N=340) predict, postdict, and respond emotionally whether novel agents selectively donate scarce resources to former benefactors, triangulating measures of anticipatory-looking, violation-of-expectation, and emotional responses across six experiments. These results indicate that dedicated psychological coordination mechanisms for direct reciprocity form such basic building-blocks of the human mind that they help humans recognize and appropriately navigate reciprocal coordination already from preverbal infancy onwards.

  Society is characterized by the negotiation of group interests, often favoring stronger majority groups. Preverbal infants expect members of larger coalitions to prevail in concrete conflicts, but it remains unknown whether infants parse the social world by ascribing general default coalitional formidability motives to oth- ers, even in the absence of intergroup conflict. Here we show that 9–13-month- old Norwegian infants (N = 97) expected an agent to approach the larger of two separate, coordinated groups (Cohen’s g = .15–.17), directing their anticipatory gaze toward the larger of two groups as a third-party agent began moving to- ward them. Supporting the specificity of this looking pattern to group-choice prediction, the effect did not extend to larger sets of objects (Cohen’s g = −.11, N = 38), nor to larger groups when the third-party agent moved away from the groups rather than approaching them (Cohen’s g = −.05, N = 33). North American and Norwegian adults similarly predicted that a third-party agent would choose the larger group across explicit (N = 1704, d > .11) and implicit measures (N = 33, Cohen’s g = .23). Humans infer third-party group formidability motives across ontogeny.

  To sustain the evolution of cooperation, individuals must recognize and discriminate against non-cooperators. Trivers (1971) posited that gratitude is part of the reciprocal system, moving individuals to return favors. We hypothesize that displays of gratitude engender trust, thereby increasing benefactors' willingness to invest in individuals who express gratitude, even in the face of the potential risk of not receiving a return on their investment. We tested this by implementing a modified Trust Game for preschoolers. Children aged 4 - 6 decided whether to give candies to grateful, ungrateful, or neutral characters. If the child chose to give candy, the recipient received three additional candies, which could either be retained or shared back with the child, presenting an investment risk - losing their candy or gaining more than if they kept their candy for themselves. Two studies involving Italian (N = 56) and Norwegian (N = 70) preschoolers showed that they preferentially invested in the grateful recipient over ungrateful or neutral characters. No significant difference was observed between ungrateful and neutral characters. This suggests that gratitude signals altruistic intent, fostering trust and promoting further cooperation.
