Transcultural pathways to the will to fight.

In 2022, the "Will to Fight Act" was referred to the US Congress urging attention to measuring and assessing will to fight. That Bill was not enacted, and evaluation efforts within the political and military establishment remain contentious, fragmented, and meager. This likely will persist, along with attendant policy failures and grievous costs, without awareness of research that the social and psychological sciences reveal on the will to fight [S. Atran, Science 373, 1063 (2021)]. We illustrate such research using converging data from a multimethod and multicultural approach, including field and online studies from the Middle East, North Africa, and Europe. These studies reveal specific psychosocial pathways, within a general causal framework, that predict willingness to make costly sacrifices, including to cooperate, fight, and die in war and sustained conflict. From the continuing strife in Iraq to embattled Ukraine, 31 studies were conducted in 9 countries with nearly 12,000 participants. These include people in longstanding conflicts, refugees, imprisoned jihadists and gangs, US military, studies in Ukraine before and during the current war, and rolling studies with a European ally of Ukraine. Results provide evidence for a mediation model of transcultural pathways to the will to fight. Building on our previous behavioral and brain research, on the battlefield in Iraq, with violent extremists, and with US military, the linear mediation yielding the will to fight involves identity fusion, perceived spiritual formidability, and trust. The model, a variation on "The Devoted Actor Framework," applies to primary reference groups, core cultural values, and leaders.

Spiritual over physical formidability determines willingness to fight and sacrifice through loyalty in cross-cultural populations.

Across 11 studies involving six countries from four continents (n = 3,285), we extend insights from field investigations in conflict zones to offline and online surveys to show that personal spiritual formidability-the conviction and immaterial resources (values, strengths of beliefs, character) of a person to fight-is positively associated with the will to fight and sacrifice for others. The physical formidability of groups in conflict has long been promoted as the primary factor in human decisions to fight or flee in times of conflict. Here, studies in Spain, Iraq, Lebanon, Palestine, and Morocco reveal that personal spiritual formidability, a construct distinct from religiosity, is more strongly associated with the willingness to fight and make costly self-sacrifices for the group than physical formidability. A follow-on study among cadets of the US Air Force Academy further indicates that this effect is mediated by a stronger loyalty to the group, a finding replicated in a separate study with a European sample. The results demonstrate that personal spiritual formidability is a primary determinant of the will to fight across cultures, and this individual-level factor, propelled by loyal bonds made with others, disposes citizens and combatants to fight at great personal risk.

Parental Nurturance Moderates the Etiology of Youth Resilience.

Parenting behaviors are among the most robust predictors of youth resilience to adversity. Critically, however, very few studies examining these effects have been genetically-informed, and none have considered parenting as an etiologic moderator of resilience. What's more, despite the multidimensionality of resilience, extant etiologic literature has largely focused on a single domain. The current study sought to fill these respective gaps in the literature by examining whether and how parental nurturance shapes the etiology of academic, social, and psychological resilience, respectively. We employed a unique sample of twins (N = 426 pairs; ages 6-11) exposed to moderate-to-severe levels of environmental adversity (i.e., family poverty, neighborhood poverty, community violence) from the Twin Study of Behavioral and Emotional Development in Children. As expected, parental nurturance was positively correlated with all forms of resilience. Extended univariate genotype-by-environment interaction models revealed that parental nurturance significantly moderated genetic influences on all three domains of resilience (academic resilience A1= -0.53, psychological resilience A1= -1.22, social resilience A1= -0.63; all p < .05), such that as parental nurturance increased, genetic influences on youth resilience decreased. Put another way, children experiencing high levels of parental nurturance were more resilient to disadvantage, regardless of their genetic predisposition towards resilience. In the absence of nurturing parenting, however, genetic influences played an outsized role in the origins of resilience. Such findings indicate that parental nurturance may serve as a malleable protective factor that increases youth resilience regardless of genetic influences.

Elucidating the role of negative parenting in the genetic v. environmental influences on adult psychopathic traits.

BACKGROUND: Psychopathic traits involve interpersonal manipulation, callous affect, erratic lifestyle, and antisocial behavior. Though adult psychopathic traits emerge from both genetic and environmental risk, no studies have examined etiologic associations between adult psychopathic traits and experiences of parenting in childhood, or the extent to which parenting practices may impact the heritability of adult psychopathic traits using a genetically-informed design. METHODS: In total, 1842 adult twins from the community reported their current psychopathic traits and experiences of negative parenting during childhood. We fit bivariate genetic models to the data, decomposing the variance within, and the covariance between, psychopathic traits and perceived negative parenting into their genetic and environmental components. We then fit a genotype × environment interaction model to evaluate whether negative parenting moderated the etiology of psychopathic traits. RESULTS: Psychopathic traits were moderately heritable with substantial non-shared environmental influences. There were significant associations between perceived negative parenting and three of four psychopathy facets (interpersonal manipulation, erratic lifestyle, antisocial tendencies, but not callous affect). These associations were attributable to a common non-shared environmental pathway and not to overlapping genetic effects. Additionally, we found that primarily shared environmental influences were stronger on psychopathic traits for individuals with a history of greater negative parenting. CONCLUSIONS: Utilizing a genetically-informed design, we found that both genetic and non-shared environmental factors contribute to the emergence of psychopathic traits. Moreover, perceptions of negative parenting emerged as a clear environmental influence on the development of interpersonal, lifestyle, and antisocial features of psychopathy.

Genetic versus environmental influences on callous-unemotional traits in preadolescence: The role of parenting and parental psychopathology.

Children with callous-unemotional (CU) traits are at risk for severe conduct problems. While CU traits are moderately heritable, parenting also predicts risk. However, few studies have investigated whether parenting factors (e.g., acceptance, conflict, parental psychopathology) moderate the etiology of CU traits, while accounting for gene-environment correlations. To address this knowledge gap, we used data from 772 twin pairs from the Adolescent Brain and Cognitive Development Study to test bivariate models that explored overlapping etiological influences on CU traits and child reports of their parenting environment. We also used gene-by-environment interaction models to test whether parenting moderated genetic versus environmental influences. There were no overlapping etiological influences on CU traits and parental acceptance, but modest genetic and non-shared environmental overlap between CU traits and family conflict. Parental acceptance and psychopathology moderated non-shared environmental influences, with stronger non-shared environmental influences on CU traits among children who experienced lower parental acceptance and greater parental psychopathology. Family conflict only moderated environmental influences when models did not covary for conduct problems. Parental acceptance and parental psychopathology may be specific environmental protective and risk factors for CU traits, whereas family conflict may represent a general environmental risk factor for both CU traits and conduct problems.

Exploring the intergroup consequences of majority members' perceptions that minority members want majority members to adopt the minority culture.

There remains an obvious gap in the acculturation literature, which relates to cultural change associated with the majority/dominant group. This paper explores how majority members react to a perceived expectation from minority members that majority members should undergo cultural change. A study was conducted exploring how majority members' perceptions of a demand by minority members that the majority should adopt the minority culture affects the majority members' preferences for minority acculturation, and whether effects are mediated by perceptions of symbolic threat. Two hundred sixty-six participants who self-reported being white British completed an online survey. A model was hypothesized whereby a perception that minority members demand that the majority takes on the minority culture predicted perceived symbolic threat, which was in turn negatively associated with a desire that minority members should maintain the minority culture, and positively with a desire that minority members should adopt the majority culture. Results supported the hypothesized model, with all individual paths and indirect effects significant in the hypothesized directions. Symbolic threat mediated the effect of perceived demand for minority culture adoption on majority preferences for minority acculturation. Findings are discussed in relation to implications for intergroup relations in culturally plural societies.

How we think they see us? Valence and difficulty of retrieval as moderators of the effect of meta-stereotype activation on intergroup orientations.

Previous research indicates that meta-stereotypes are predominantly negative. However, the valence of the meta-stereotypes may not be the only factor accounting for the detrimental effects associated with their activation. In addition to valence, we propose that the subjective difficulty of retrieving the meta-stereotype might critically determine whether its activation deteriorates intergroup orientations. An experimental study showed that the effect of the meta-stereotype activation on the desire to interact with outgroup members was moderated by the interaction between the valence of the meta-stereotype and its difficulty of retrieval. In particular, the activation of a positive meta-stereotype deteriorated intergroup orientations when the difficulty of retrieval was high as compared with a condition in which the difficulty of retrieval was low. In sharp contrast, the activation of a negative meta-stereotype worsened intergroup orientations when the difficulty of retrieval was low as compared with a condition in which the difficulty of retrieval was high.

Fusion with the Cross-Gender Group Predicts Genital Sex Reassignment Surgery.

Transsexuals vary in the sacrifices that they make while transitioning to their cross-gender group. We suggest that one influence on the sacrifices they make is identity fusion. When people fuse with a group, a visceral and irrevocable feeling of oneness with the group develops. The personal self (the sense of "I" and "me") remains potent and combines synergistically with the social self to motivate behavior. We hypothesized that transsexuals who felt fused with the cross-gender group would be especially willing to make sacrifices while transitioning to that group. Our sample included 22 male-to-female (MtF) and 16 female-to-male (FtM) transsexuals. Consistent with expectation, those who were fused with their cross-gender group (1) expressed more willingness to sacrifice close relationships in the process of changing sex than non-fused transsexuals and (2) actually underwent irreversible surgical change of their primary sexual characteristics (vaginoplasty for MtF transsexuals and hysterectomy for FtM transsexuals). These outcomes were not predicted by a measure of "group identification," which occurs when membership in the group eclipses the personal self (the "I" and "me" is subsumed by the group; in the extreme case, brainwashing occurs). These findings confirm and extend earlier evidence that identity fusion is uniquely effective in tapping a propensity to make substantial sacrifices for the group. We discuss identity fusion as a social psychological determinant of the choices of transsexuals.

Not all ballots should be considered equal: How education-based dehumanization undermines the democratic social contract.

Less educated people are viewed negatively and their opinions are belittled in our society. Besides, along with other groups, they are underrepresented in the political arena which questions the legitimacy of democratic systems. Despite the existence of education-based devaluation, research on how people dehumanize individuals and groups with lesser education and minimize their democratic rights is scarce. In this project, we provide correlational evidence that less (vs. highly) educated individuals and groups are dehumanized (Study 1a, N = 304) and their democratic rights (voting, running for office) are questioned (Study 1b, N = 504). Furthermore, we identified that dehumanization tendencies of the less (vs. highly) educated targets predict support for denying them voting rights or the capability to run for public candidacies (Study 2, N = 447). Finally, an experimental study confirmed that the target's educational background influences attributions of humanity, which in turn seem to affect the denial of democratic rights to the target (Study 3, N = 470). These findings suggest that education-based dehumanization might undermine the inalienable democratic rights of lesser educated individuals and groups thus endangering the foundations of democratic systems.

Does the union always make the force? Group status and recategorization influence the perceived physical formidability of potential coalition groups.

Coalitions among individuals and between groups, which have had critical evolutionary benefits for humans, play an important role in contemporary life. One key element of the processes of assessing potential allies is how they may contribute to the perceived physical formidability - fighting ability or the capacity to inflict costs on others - of the alliance. In three studies, focused for the first time on intergroup coalitions, we investigated how qualities of the groups such as status (social prestige) and the relationship between them influence the perceived physical formidability of a coalition (i.e., European Union, EU). Study 1 found that the inclusion of a group with higher or similar (but not lower) status increased the perceived formidability of the EU. Studies 2 and 3 showed that learning that ingroup members recategorized a low-status group within a common-group identity increased the perceived formidability of the EU including that group, compared with the conditions in which either outgroup members recategorized or no information was provided. Study 3 also revealed mediation by fusion - a visceral connection - with outgroup members, which has been relatively unexplored. Taken together, these studies reveal that both, status and social identity processes, may significantly affect the estimations of coalitional formidability.

Exploring the origins of identity fusion: Shared emotional experience activates fusion with the group over time.

Identity fusion is a visceral feeling of oneness with a group, known to strongly motivate extreme pro-group behaviour. However, the evidence on its causes is currently limited, primarily due to the prevalence of cross-sectional research. To address this gap, this study analysed the evolution of fusion in response to a massive collective ritual, Korrika-a race in support of the Basque language-, over three time periods: before (n = 748) and immediately following participation (n = 402), and 7 weeks thereafter (n = 273). Furthermore, we explored the potential mediating roles of two key factors: perceived emotional synchrony, a sense of emotional unity among participants that emerges during collective rituals, and kama muta (moved by love), an unexplored emotion in relation to fusion, which arises from feelings of shared essence. The proportion of fused participants increased significantly after participation and remained stable for at least 7 weeks. Perceived emotional synchrony and kama muta apparently explained the effect of participants' behavioural involvement in the ritual on subsequent fusion, but only among those who were not previously fused with Korrika participants. We conclude that emotional processes during collective rituals play a fundamental role in the construction of identity fusion.

The Role of Subjective Socioeconomic Status in Predicting Academic Performance: Exploring the Mediating Influence of Sense of Belonging among Students in a Distance Learning University.

Building upon existing research conducted in face-to-face universities, our research explored whether, in the context of a distance learning institution, the positive association between subjective socioeconomic status and academic performance can be explained by students' sense of belonging. To that end, we conducted a three-wave correlational study with 2,261 students enrolled in Social Psychology in a distance learning university. At the start of the academic year, we measured participants' subjective socioeconomic status relative to other students alongside their initial expectations in terms of time investment and grades and other relevant covariates. Midway through the course, we assessed their sense of belonging to the university and, at the end, we recorded their grades. Results suggested that sense of belonging potentially serves as a mediating factor in the positive relationship between subjective socioeconomic status and grades even after accounting for variables like initial grade expectations, time commitment, gender, age, and employment situation. These findings emphasize the pivotal role of students' psychological connection to the university in shaping their academic achievement, even within the expanding landscape of distance education.

Neighborhood features moderate genetic and environmental influences on children's social information processing.

Neighborhood is a key context where children learn to process social information; however, the field has largely overlooked the ways children's individual characteristics might be moderated by neighborhood effects. We examined 1,030 six- to 11-year-olds (48.7% female; 82% White) twin pairs oversampled for neighborhood disadvantage from the Twin Study of Behavioral and Emotional Development in Children. We evaluated neighbor reports (N = 1,880) of neighborhood structural and social characteristics as moderators of genetic and environmental influences on children's social processing. Although there was no evidence of moderation for children's hostile attributions, there was robust evidence that the social and structural characteristics of the neighborhood moderated the genetic and environmental origins of children's positive expectations of aggressive behavior. Specifically, we found that genetic influences on aggressive expectations increased in the presence of neighborhood deprivation and decreased in the presence of protective social processes and availability of resources. Such findings suggest that protective neighborhood social processes may buffer against the development of aggressive expectations during middle childhood by suppressing the expression of genetic influences on those outcomes. In doing so, they suggest that neighborhood social processes may be able to promote youth resilience to neighborhood deprivation "under the skin."

Feeling understood fosters identity fusion.

If the consequences of identity fusion are well established, its psychological antecedents are not. To address this shortcoming, eight studies tested the hypothesis that self-verification (receiving evaluations that confirm one's self-views) increases fusion (a synergistic union with a group, individual, or cause), which, in turn, increases behavioral support for the target of fusion. Correlational studies showed that perceived self-verification was positively associated with fusion, which was positively associated with willingness to fight and die for a group (Study 1a), a value (Study 1b), and a leader (Study 1c). Study 2 revealed that increasing perceived self-verification fostered greater willingness to fight and die for the group but only indirectly through increases in fusion. Study 3 showed that 4 months after indicating the degree of fusion with a group, increasing perceived self-verification augmented endorsement of fighting and dying for the group indirectly through elevations in fusion. In Study 4, relational ties mediated the relationship between perceived self-verification and fusion. Finally, face-to-face interviews with incarcerated members of street gangs and organized crime gangs (Studies 5a-5b) showed that perceived self-verification was positively associated with fusion, which was positively associated with sacrifices for the gang (replicating Studies 1a-1c). No evidence emerged supporting a rival causal path in which fusion caused willingness to fight and die through perceived self-verification. Implications for related theoretical approaches and for conceptualizing the relationship between personal identities, social identities, and group processes are discussed.

Associations of depression and anxiety symptoms in childhood and adolescence with epigenetic aging.

BACKGROUND: Childhood anxiety and depression symptoms are potential risk factors for accelerated biological aging. In child and adolescent twins, we tested whether these symptoms were associated with DNA methylation (DNAm) aging, a measure of biological aging. METHODS: 276 twins (135 pairs, 6 singletons) had DNAm assayed from saliva in middle childhood (mean = 7.8 years). Residuals of five different DNAm age estimates regressed on chronological age were used to indicate accelerated aging. Anxiety and depression symptoms were assessed in middle childhood and early adolescence using the Child Behavior Checklist. Mixed effect regression was used to examine potential relationships between anxiety or depression symptoms, and accelerated DNAm age. MZ twin difference analysis was then utilized to determine if associations were environmentally-driven or due to genetic or shared-environment confounding. RESULTS: Anxiety and depression symptoms were not associated with accelerated DNAm aging in middle childhood. In early adolescence, only the Wu clock was significant and indicated that each one symptom increase in anxiety symptoms had an associated age acceleration of 0.03 years (~0.4 months; p = 0.019). MZ twin difference analysis revealed non-significant within-pair effects, suggesting genetic and shared environmental influences. LIMITATIONS: Sample is predominantly male and white. Generalizability to other populations may be limited. CONCLUSION: Accelerated DNAm aging of the Wu clock in middle childhood is associated with anxiety, but not depression, symptoms in early adolescence. Further, this association may be the result of shared genetic and environmental influences. Accelerated DNAm aging may serve as an early risk factor or predictor of later anxiety symptoms.

Self-uniqueness increases women's willingness to participate in collective action for gender justice, but not support for sex quotas.

Affiliation with certain groups allows to simultaneously satisfy two competing needs: the need to be moderately different from others and the need to belong. We propose that the feminist movement, that has been turning towards individualistic goals based on individual empowerment, may be one of such groups for women. In three studies we examined the relationship between self-uniqueness and women's support for collective action and structural measures (i.e. sex quotas) promoted by the feminist movement. A first correlational study indicated that self-uniqueness need is positively associated with willingness to participate in collective action for gender justice generally, but not with support for sex quotas. Consistently, two experimental studies (Studies 2-3) found that priming self-uniqueness increases collective action intentions, but not quota support. Study 3 also showed that the effect of self-uniqueness on collective action intentions for gender justice may be mediated by greater perceptions of personal discrimination for being a woman and fusion with the feminist movement. These results suggest that appeals to self-uniqueness may attract women to the feminist movement but do not guarantee support for concrete collective measures against gender inequality.

The values we share: A multi-method approach to understanding how perceived outgroup values are related to attitudes towards immigrants.

Cultural understanding entails a recognition of outgroup values. Combining quantitative and qualitative methods, we analysed the perception of Spaniards of the core values of Moroccan immigrants across two online surveys, 139 interviews and an experimental study. In Study 1, participants spontaneously generated the values considered fundamental for Moroccans, rated such values on a continuum of negativity-positivity and reported their attitudes towards Moroccans. In Study 2, participants were asked about the values that Spaniards and Moroccans (do not) share. In Study 3, participants were interviewed about the core values for Moroccans and those shared with Spaniards. Study 4 experimentally manipulated the salience of value-sharing. An inductive analysis revealed that the perceived core values for Moroccans were related to family/community, material issues, religion and integrity. Study 2 showed that religion, gender-universalism and culture/tradition were perceived as different values, whereas integrity, social-interaction and family/community values were perceived as shared. Study 4 confirmed that making salient the common importance of family for Spaniards and Moroccans indirectly increased the perceived morality of Moroccan immigrants via perceived shared values. Implications for the way lay people think about the values of outgroups are discussed.

Why Is It so Difficult to Investigate Violent Radicalization?

Imagine that you are a researcher interested in disentangling the underlying mechanisms that motivate certain individuals to self-sacrifice for a group or an ideology. Now, visualize that you are one of a few privileged that have the possibility of interviewing people who have been involved in some of the most dramatic terrorist attacks in history. What should you do? Most investigations focused on terrorism do not include empirical data and just a handful of fortunate have made face-to-face interviews with these individuals. Therefore, we might conclude that most experts in the field have not directly met the challenge of experiencing studying violent radicalization in person. As members of a research team who have talked with individuals under risk of radicalization, current, and former terrorists, our main goal with this manuscript is to synopsize a series of ten potential barriers that those interested in the subject might find when making fieldwork, and alternatives to solve them. If all the efforts made by investigators could save the life of a potential victim, prevent an individual from becoming radicalized, or make him/her decide to abandon the violence associated with terrorism, all our work will have been worthwhile.

Clinical utility of the Bem Sex Role Inventory (BSRI) in the Spanish transsexual and nontranssexual population.

The aim of the study is to evaluate the usefulness of the Bem Sex Role Inventory (BSRI; Bem, 1974), an overall measurement of the cultural construct of masculinity and femininity, in the psychological assessment of Spanish transsexuals. Seventy male-to-female transsexuals (MF), 51 female-to-male transsexuals (FM), 77 control men, and 79 control women completed the Spanish version of the BSRI. Statistically significant differences between groups were only found on the femininity scale, on which MF transsexuals and control women scored significantly higher than FM transsexuals and control men. The results indicate that (a) only the femininity scale of the BSRI appears to be useful today for evaluating differences in the sex-role identification in Spanish controls and transsexuals; and (b) MF and FM transsexuals score as a function of their gender identity instead of their anatomical sex on the BSRI femininity scale.

Strongly fused individuals feel viscerally responsible to self-sacrifice.

Identity fusion is a visceral feeling of oneness that predicts extreme behaviour on behalf of the target of fusion. We propose that strongly fused individuals are characterized by feelings of visceral responsibility towards such target - unconditional, instinctive, and impulsive drive to care, protect and promote its well-being and interests - that motivates them to self-sacrifice. Two studies offered initial support when the target of fusion is an individual or a group (Studies 1a-1b). A final study added causal evidence that strongly fused learning that most ingroup members did not feel visceral responsibility towards the group expressed less willingness to self-sacrifice than those learning that ingroup members display high levels of visceral responsibility (Study 2). These findings offer novel evidence for the mechanisms underlying the effects of fusion on extreme behaviour on behalf of the target of fusion and the attenuation of its consequences.
