Moral foundations and HPV vaccine acceptance in the United States: State, parental, and individual factors.

RATIONALE: Appeals to intuitive morality may present a novel approach to addressing vaccine hesitancy. OBJECTIVE: To better understand the relationship between morality and vaccination by employing Moral Foundations Theory to studies surrounding the HPV vaccination at multiple different levels of decision making. METHOD: We employed three different study modalities which examined moralities link to vaccination by employing Moral Foundations Theory. A state-wide ecological study aimed to understand population level trends. Two randomized control interventional studies were then created to understand the effects of Moral Foundations Theory based interventions on both parents of children and individual decision makers. RESULTS: We demonstrated a negative association at the state level between the purity moral foundations and HPV vaccination rates (ß = -.75, SE 0.23; p < .01) and a positive association between loyalty and HPV vaccination rates (ß = 0.62 SE 0.24; p < .05). The parental study built upon this by demonstrating negative association between higher moral purity scores and attitudes towards the HPV vaccine and intention to vaccinate their children (ß = -0.27 SE 0.07; p < .001). Our final study demonstrated a Moral Foundations Theory based intervention was associated with an increase in the odds of indicating an intention to receive the HPV vaccination (adjusted Odds Ratio (aOR) 2.59, 95% Confidence Interval (CI) 1.62-4.14). This equates to a 20% increase in the predicted probability of the intention to receive an HPV vaccine (39% CI (36%-42%) vs 60% CI (57%-63%). CONCLUSIONS: Together, these studies demonstrate that moral foundations, specifically the purity foundation, appear to have a strong and consistent relationship with HPV vaccination. They also demonstrate the how moral values-based interventions may serve as a novel approach to increase HPV vaccine uptake with potential to be employed to target vaccine hesitancy more broadly.

Puritanism needs purity, and moral psychology needs pluralism.

This account of puritanical morality is useful and innovative, but makes two errors. First, it mischaracterizes the purity foundation as being unrelated to cooperation. Second, it makes the leap from cooperation (broadly construed) to a monist account of moral cognition (as harm or fairness). We show how this leap is both conceptually incoherent and inconsistent with empirical evidence about self-control moralization.

Morality beyond the WEIRD: How the nomological network of morality varies across cultures.

Moral foundations theory has been a generative framework in moral psychology in the last 2 decades. Here, we revisit the theory and develop a new measurement tool, the Moral Foundations Questionnaire-2 (MFQ-2), based on data from 25 populations. We demonstrate empirically that equality and proportionality are distinct moral foundations while retaining the other four existing foundations of care, loyalty, authority, and purity. Three studies were conducted to develop the MFQ-2 and to examine how the nomological network of moral foundations varies across 25 populations. Study 1 (N = 3,360, five populations) specified a refined top-down approach for measurement of moral foundations. Study 2 (N = 3,902, 19 populations) used a variety of methods (e.g., factor analysis, exploratory structural equations model, network psychometrics, alignment measurement equivalence) to provide evidence that the MFQ-2 fares well in terms of reliability and validity across cultural contexts. We also examined population-level, religious, ideological, and gender differences using the new measure. Study 3 (N = 1,410, three populations) provided evidence for convergent validity of the MFQ-2 scores, expanded the nomological network of the six moral foundations, and demonstrated the improved predictive power of the measure compared with the original MFQ. Importantly, our results showed how the nomological network of moral foundations varied across cultural contexts: consistent with a pluralistic view of morality, different foundations were influential in the network of moral foundations depending on cultural context. These studies sharpen the theoretical and methodological resolution of moral foundations theory and provide the field of moral psychology a more accurate instrument for investigating the many ways that moral conflicts and divisions are shaping the modern world.

The paucity of morality in everyday talk.

Given its centrality in scholarly and popular discourse, morality should be expected to figure prominently in everyday talk. We test this expectation by examining the frequency of moral content in three contexts, using three methods: (a) Participants' subjective frequency estimates (N = 581); (b) Human content analysis of unobtrusively recorded in-person interactions (N = 542 participants; n = 50,961 observations); and (c) Computational content analysis of Facebook posts (N = 3822 participants; n = 111,886 observations). In their self-reports, participants estimated that 21.5% of their interactions touched on morality (Study 1), but objectively, only 4.7% of recorded conversational samples (Study 2) and 2.2% of Facebook posts (Study 3) contained moral content. Collectively, these findings suggest that morality may be far less prominent in everyday life than scholarly and popular discourse, and laypeople, presume.

Who attributes what to whom? Moral values and relational context shape causal attribution to the person or the situation.

Eight preregistered studies (total N = 3,758) investigate the role of values and relational context in attributions for moral violations, focusing on the following questions: (1) Do people's values influence their attributions? (2) Do people's relationships with the violator (self, close other, distant other) influence their attributions? (3) Do the principles intrinsic to the violated values (e.g., loyalty to close others) further influence their attributions? We found that participants were more likely to attribute violations by distant others to the person committing the violation, rather than the situation in which the violation occurred, when participants endorsed the violated values themselves. The tendency to make dispositional attributions did not obtain for violations of participants' less highly endorsed moral values or non-moral values. Relationship with the violator also influenced participants' attributions-participants were more likely to attribute their own and close others' moral violations to situational factors, relative to distant others' violations. This relational pattern was pronounced for violations of "binding" moral values, in which protection of personal relationships and groups is primary. Collectively, these results support a relational-values account of causal attribution for moral violations, whereby attributions systematically vary based on (1) the relevance of the violated values to the attributor's moral values, (2) the attributor's personal relationship to the violator, and (3) an interaction between (1) and (2) such that the principles intrinsic to the violated values influence the effects of one's relationship to the violator.

Moral values predict county-level COVID-19 vaccination rates in the United States.

Despite the widespread availability of COVID-19 vaccines, the United States has a depressed rate of vaccination relative to similar countries. Understanding the psychology of vaccine refusal, particularly the possible sources of variation in vaccine resistance across U.S. subpopulations, can aid in designing effective intervention strategies to increase vaccination across different regions. Here, we demonstrate that county-level moral values (i.e., Care, Fairness, Loyalty, Authority, and Purity) are associated with COVID-19 vaccination rates across 3,106 counties in the contiguous United States. Specifically, in line with our hypothesis, we find that fewer people are vaccinated in counties whose residents prioritize moral concerns about bodily and spiritual purity. Further, we find that stronger endorsements of concerns about Fairness and Loyalty to the group predict higher vaccination rates. These associations are robust after adjusting for structural barriers to vaccination, the demographic makeup of the counties, and their residents' political voting behavior. Our findings have implications for health communication, intervention strategies based on targeted messaging, and our fundamental understanding of the moral psychology of vaccination hesitancy and behavior.

Moral concerns are differentially observable in language.

Language is a psychologically rich medium for human expression and communication. While language usage has been shown to be a window into various aspects of people's social worlds, including their personality traits and everyday environment, its correspondence to people's moral concerns has yet to be considered. Here, we examine the relationship between language usage and the moral concerns of Care, Fairness, Loyalty, Authority, and Purity as conceptualized by Moral Foundations Theory. We collected Facebook status updates (N = 107,798) from English-speaking participants (n = 2691) along with their responses on the Moral Foundations Questionnaire. Overall, results suggested that self-reported moral concerns may be traced in language usage, though the magnitude of this effect varied considerably among moral concerns. Across a diverse selection of Natural Language Processing methods, Fairness concerns were consistently least correlated with language usage whereas Purity concerns were found to be the most traceable. In exploratory follow-up analyses, each moral concern was found to be differentially related to distinct patterns of relational, emotional, and social language. Our results are the first to relate individual differences in moral concerns to language usage, and to uncover the signatures of moral concerns in language.

Political differences in free will belief are associated with differences in moralization.

In 14 studies, we tested whether political conservatives' stronger free will beliefs were linked to stronger and broader tendencies to moralize and, thus, a greater motivation to assign blame. In Study 1 (meta-analysis of 5 studies, n = 308,499) we show that conservatives have stronger tendencies to moralize than liberals, even for moralization measures containing zero political content (e.g., moral badness ratings of faces and personality traits). In Study 2, we show that conservatives report higher free will belief, and this is statistically mediated by the belief that people should be held morally responsible for their bad behavior (n = 14,707). In Study 3, we show that political conservatism is associated with higher attributions of free will for specific events. Turning to experimental manipulations to test our hypotheses, we show the following: when conservatives and liberals see an action as equally wrong there is no difference in free will attributions (Study 4); when conservatives see an action as less wrong than liberals, they attribute less free will (Study 5); and specific perceptions of wrongness account for the relation between political ideology and free will attributions (Study 6a and 6b). Finally, we show that political conservatives and liberals even differentially attribute free will for the same action depending on who performed it (Studies 7a-d). These results are consistent with our theory that political differences in free will belief are at least partly explicable by conservatives' tendency to moralize, which strengthens motivation to justify blame with stronger belief in free will and personal accountability.

Ideology, shared moral narratives, and the dark side of collective rationalization.

This commentary extends the target article's useful concepts to consider collective instances of representational exchange. When groups collectively rationalize their actions, entire networks of beliefs and desires can be created and maintained in the form of shared moral narratives and system-justifying ideologies. These collective rationalization cases illustrate how adaptive advantages can come at the expense of the truth.

Conservatives Report Greater Meaning in Life than Liberals.

Conservatives report greater life satisfaction than liberals, but this relationship is relatively weak. To date, the evidence is limited to a narrow set of well-being measures that ask participants for a single assessment of their life in general. We address this shortcoming by examining the relationship between political orientation and well-being using measures of life satisfaction, affect, and meaning and purpose in life. Participants completed well-being measures after reflecting on their whole life (Studies 1a, 1b, and 2), at the end of their day (Study 3), and in the present moment (Study 4). Across five studies, conservatives reported more meaning and purpose in life than liberals at each reporting period. This finding remained significant after adjusting for religiosity and was usually stronger than the relationships involving other well-being measures. Finally, meaning in life was more closely related to social conservatism than economic conservatism.

Ideological differences in the expanse of the moral circle.

Do clashes between ideologies reflect policy differences or something more fundamental? The present research suggests they reflect core psychological differences such that liberals express compassion toward less structured and more encompassing entities (i.e., universalism), whereas conservatives express compassion toward more well-defined and less encompassing entities (i.e., parochialism). Here we report seven studies illustrating universalist versus parochial differences in compassion. Studies 1a-1c show that liberals, relative to conservatives, express greater moral concern toward friends relative to family, and the world relative to the nation. Studies 2a-2b demonstrate these universalist versus parochial preferences extend toward simple shapes depicted as proxies for loose versus tight social circles. Using stimuli devoid of political relevance demonstrates that the universalist-parochialist distinction does not simply reflect differing policy preferences. Studies 3a-3b indicate these universalist versus parochial tendencies extend to humans versus nonhumans more generally, demonstrating the breadth of these psychological differences.

Acknowledging and managing deep constraints on moral agency and the self.

Doris proposes that the exercise of morally responsible agency unfolds as a collaborative dialogue among selves expressing their values while being subject to ever-present constraints. We assess the fit of Doris's account with recent data from psychology and neuroscience related to how people make judgments about moral agency (responsibility, blame), and how they understand the self after traumatic events.

Resisting temptation for the good of the group: Binding moral values and the moralization of self-control.

When do people see self-control as a moral issue? We hypothesize that the group-focused "binding" moral values of Loyalty/betrayal, Authority/subversion, and Purity/degradation play a particularly important role in this moralization process. Nine studies provide support for this prediction. First, moralization of self-control goals (e.g., losing weight, saving money) is more strongly associated with endorsing binding moral values than with endorsing individualizing moral values (Care/harm, Fairness/cheating). Second, binding moral values mediate the effect of other group-focused predictors of self-control moralization, including conservatism, religiosity, and collectivism. Third, guiding participants to consider morality as centrally about binding moral values increases moralization of self-control more than guiding participants to consider morality as centrally about individualizing moral values. Fourth, we replicate our core finding that moralization of self-control is associated with binding moral values across studies differing in measures and design-whether we measure the relationship between moral and self-control language across time, the perceived moral relevance of self-control behaviors, or the moral condemnation of self-control failures. Taken together, our findings suggest that self-control moralization is primarily group-oriented and is sensitive to group-oriented cues. (PsycINFO Database Record

Dehumanization increases instrumental violence, but not moral violence.

Across five experiments, we show that dehumanization-the act of perceiving victims as not completely human-increases instrumental, but not moral, violence. In attitude surveys, ascribing reduced capacities for cognitive, experiential, and emotional states to victims predicted support for practices where victims are harmed to achieve instrumental goals, including sweatshop labor, animal experimentation, and drone strikes that result in civilian casualties, but not practices where harm is perceived as morally righteous, including capital punishment, killing in war, and drone strikes that kill terrorists. In vignette experiments, using dehumanizing compared with humanizing language increased participants' willingness to harm strangers for money, but not participants' willingness to harm strangers for their immoral behavior. Participants also spontaneously dehumanized strangers when they imagined harming them for money, but not when they imagined harming them for their immoral behavior. Finally, participants humanized strangers who were low in humanity if they imagined harming them for immoral behavior, but not money, suggesting that morally motivated perpetrators may humanize victims to justify violence against them. Our findings indicate that dehumanization enables violence that perpetrators see as unethical, but instrumentally beneficial. In contrast, dehumanization does not contribute to moral violence because morally motivated perpetrators wish to harm complete human beings who are capable of deserving blame, experiencing suffering, and understanding its meaning.

Association of moral values with vaccine hesitancy.

Clusters of unvaccinated children are particularly susceptible to outbreaks of vaccine-preventable disease 1,2 . Existing messaging interventions demonstrate short-term success, but some may backfire and worsen vaccine hesitancy 3 . Values-based messages appeal to core morality, which influences the attitudes individuals then have on topics like vaccination 4-7 . We must understand how underlying morals, not just attitudes, differ by hesitancy type to develop interventions that work with individual values. Here, we show in two correlational studies that harm and fairness foundations are not significantly associated with vaccine hesitancy, but purity and liberty foundations are. We found that medium-hesitancy parents were twice as likely as low-hesitancy parents to highly emphasize purity (adjusted odds ratio: 2.08; 95% confidence interval: 1.27-3.40). High-hesitancy respondents were twice as likely to strongly emphasize purity (adjusted odds ratio: 2.15; 95% confidence interval: 1.39-3.31) and liberty (adjusted odds ratio: 2.19; 95% confidence interval: 1.50-3.21). Our results demonstrate that endorsement of harm and fairness-ideas often emphasized in traditional vaccine-focused messages-are not predictive of vaccine hesitancy. This, combined with significant associations of purity and liberty with hesitancy, indicates a need for inclusion of broader themes in vaccine discussions. These findings have the potential for application to other health decisions and communications as well.

Centripetal and centrifugal forces in the moral circle: Competing constraints on moral learning.

The idea of the moral circle pictures the self in the center, surrounded by concentric circles encompassing increasingly distant possible targets of moral concern, including family, local community, nation, all humans, all mammals, all living things including plants, and all things including inanimate objects. The authors develop the idea of two opposing forces in people's moral circles, with centripetal forces pulling inward, urging greater concern for close others than for distant others, and centrifugal forces pushing outward, resisting "drawing the line" anywhere as a form of prejudice and urging egalitarian concern for all regardless of social distance. Review of the developmental literature shows very early emergence of both moral forces, suggesting at least partly intuitive bases for each. Moral education approaches favoring one force over the other are compared, to show how these forces can provide constraints on moral learning. Finally, the centripetal/centrifugal forces view is applied to current moral debates about empathy and about politics. The authors argue that this view helps us see how intercultural and interpersonal disagreements about morality are based in intrapersonal conflicts shared by all people.

Data from a pre-publication independent replication initiative examining ten moral judgement effects.

We present the data from a crowdsourced project seeking to replicate findings in independent laboratories before (rather than after) they are published. In this Pre-Publication Independent Replication (PPIR) initiative, 25 research groups attempted to replicate 10 moral judgment effects from a single laboratory's research pipeline of unpublished findings. The 10 effects were investigated using online/lab surveys containing psychological manipulations (vignettes) followed by questionnaires. Results revealed a mix of reliable, unreliable, and culturally moderated findings. Unlike any previous replication project, this dataset includes the data from not only the replications but also from the original studies, creating a unique corpus that researchers can use to better understand reproducibility and irreproducibility in science.

The Immoral Assumption Effect: Moralization Drives Negative Trait Attributions.

Jumping to negative conclusions about other people's traits is judged as morally bad by many people. Despite this, across six experiments (total N = 2,151), we find that multiple types of moral evaluations--even evaluations related to open-mindedness, tolerance, and compassion--play a causal role in these potentially pernicious trait assumptions. Our results also indicate that moralization affects negative-but not positive-trait assumptions, and that the effect of morality on negative assumptions cannot be explained merely by people's general (nonmoral) preferences or other factors that distinguish moral and nonmoral traits, such as controllability or desirability. Together, these results suggest that one of the more destructive human tendencies--making negative assumptions about others--can be caused by the better angels of our nature.

Purity homophily in social networks.

Does sharing moral values encourage people to connect and form communities? The importance of moral homophily (love of same) has been recognized by social scientists, but the types of moral similarities that drive this phenomenon are still unknown. Using both large-scale, observational social-media analyses and behavioral lab experiments, the authors investigated which types of moral similarities influence tie formations. Analysis of a corpus of over 700,000 tweets revealed that the distance between 2 people in a social-network can be predicted based on differences in the moral purity content-but not other moral content-of their messages. The authors replicated this finding by experimentally manipulating perceived moral difference (Study 2) and similarity (Study 3) in the lab and demonstrating that purity differences play a significant role in social distancing. These results indicate that social network processes reflect moral selection, and both online and offline differences in moral purity concerns are particularly predictive of social distance. This research is an attempt to study morality indirectly using an observational big-data study complemented with 2 confirmatory behavioral experiments carried out using traditional social-psychology methodology.
