Abstract
If the life sciences are to have much to say about politics, there needs to be a universal element to political orientations. In this essay, I argue that the recent prominence of nativist, law-and-order, populist politicians reveals the nature of this universal element. All social units have to address bedrock dilemmas about how to deal with norm violators and how welcoming to be to outsiders as well as to proponents of new lifestyles. Might differences on these core dilemmas be the universal element of political life? Using the followers of one of the most prominent examples of a nativist political leader-Donald Trump-as an example, I present data showing that Trump's most earnest followers are different from others-even those who share their general ideological leanings-not on traditional economic or social issues, but rather on the group-based security issues that grow out of the bedrock dilemmas of social life.

Abstract
Background and objectives Pathogen avoidance is a fundamental motive that shapes many aspects of human behavior including bias against groups stereotypically linked to disease (e.g. immigrants, outgroup members). This link has only been examined in convenience samples and it is unknown how pathogen avoidance processes operate in populations experiencing prolonged and heightened pathogen threat such as healthcare professionals. We examined whether healthcare professionals demonstrate the same link between pathogen disgust and intergroup bias as has been documented among the general population. Methodology Participants (N = 317; 210 healthcare professionals) were recruited using snowball sampling to take an online survey. Participants completed the Three Domain Disgust Scale to assess pathogen, sexual and moral disgust. Participants then rated their perceptions of a fictitious immigrant group ('Krasneeans') and the degree to which they endorsed group-binding moral values. Results Compared to control participants, healthcare professionals reported lower levels of pathogen disgust, but not sexual or moral disgust. However, regardless of profession, higher pathogen disgust was associated with viewing Krasneeans as less likeable and more unclean. Additionally, regardless of profession, higher pathogen disgust was associated with greater endorsement of group-binding moral values, although healthcare professionals reported greater overall endorsement of group-binding moral values than did control participants. Conclusions and implications Although healthcare professionals demonstrated lower levels of pathogen disgust, they nevertheless exhibited largely the same relationship between pathogen disgust and interpersonal biases as did control participants. One practical implication of this association is that pathogen avoidance motives may contribute to inequitable patient treatment in healthcare settings.

Abstract
What environmental factors are associated with individual differences in political ideology, and do such associations change over time? We examine whether reductions in pathogen prevalence in U.S. states over the past 60 years are associated with reduced associations between parasite stress and conservatism. We report a positive association between infection levels and conservative ideology in the United States during the 1960s and 1970s. However, this correlation reduces from the 1980s onwards. These results suggest that the ecological influence of infectious diseases may be larger for older people who grew up (or whose parents grew up) during earlier time periods. We test this hypothesis by analyzing the political affiliation of 45,000 Facebook users, and find a positive association between self-reported political affiliation and regional pathogen stress for older (>40 years) but not younger individuals. It is concluded that the influence of environmental pathogen stress on ideology may have reduced over time.

Abstract
Immigration has become a focal debate in politics across the world. Recent research suggests that anti-immigration attitudes may have deep psychological roots in implicit disease avoidance motivations. A key implication of this theory is that individual differences in disease avoidance should be related to opposition to immigration across a wide variety of cultural and political contexts. However, existing evidence on the topic has come almost entirely from the United States and Canada. In this article, we test the disease avoidance hypothesis using nationally representative samples from Norway, Sweden, Turkey, and Mexico, as well as two diverse samples from the United States. We find consistent and robust evidence that disgust sensitivity is associated with anti-immigration attitudes and that the relationship is similar in magnitude to education. Overall, our findings support the disease avoidance hypothesis and provide new insights into the nature of anti-immigration attitudes.

Abstract
Disgust seems to play an important role in moral judgment. However, it is unclear whether the role of disgust in moral judgment is limited to certain kinds of moral domains (versus many) and/or certain types of disgust (versus many). To clarify these questions, we conducted a multilevel meta-analysis ( k = 512; N = 72,443) on relations between trait disgust sensitivity and moral judgment (disgust-immorality association). Main analyses revealed a significant overall mean disgust-immorality association ( r = .23). Additionally, moderator analyses revealed significant specificity in disgust type and moral domain (grounded in Moral Foundations Theory): effects were stronger for (a) sexual disgust compared to pathogen disgust, (b) sanctity moral judgments compared to other domains of moral judgments, and (c) sexual-sanctity associations compared to other disgust type-moral domain pairings.

Abstract
Previous work has reported a relation between pathogen-avoidance motivations and prejudice toward various social groups, including gay men and lesbian women. It is currently unknown whether this association is present across cultures, or specific to North America. Analyses of survey data from adult heterosexuals ( N = 11,200) from 31 countries showed a small relation between pathogen disgust sensitivity (an individual-difference measure of pathogen-avoidance motivations) and measures of antigay attitudes. Analyses also showed that pathogen disgust sensitivity relates not only to antipathy toward gay men and lesbians, but also to negativity toward other groups, in particular those associated with violations of traditional sexual norms (e.g., prostitutes). These results suggest that the association between pathogen-avoidance motivations and antigay attitudes is relatively stable across cultures and is a manifestation of a more general relation between pathogen-avoidance motivations and prejudice towards groups associated with sexual norm violations.

Abstract
Sitting on the fine line between pathogen 'transmissibility' and 'severity', the Behavioural Immune System (BIS) is responsible for activating behaviours that minimise infection risks and maximise fitness. To achieve self-preservation, the BIS also fuels social and political attitudes. We aim to explain societal changes that may be sparked by COVID-19 by highlighting links between human evolutionary history and our psychological faculties mediated by the BIS.

Abstract
A substantial body of research has illuminated psychological adaptations motivating pathogen avoidance, mechanisms collectively known as the behavioral immune system. Can knowledge about these mechanisms inform how people respond to widespread disease outbreaks, such as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) [coronavirus disease 2019 (COVID-19)] pandemic? We review evidence suggesting that the evolutionary history of the behavioral immune system, and the cues that activate it, are distinct in many ways from modern human experiences with pandemics. Moreover, the behaviors engaged by this system may have limited utility for combating pandemic diseases like COVID-19. A better understanding of the points of distinction and points of overlap between our evolved pathogen-avoidance psychology and responses to pandemics may help us realize a more precise and intervention-ready science.

Abstract
To understand the consequences of cleansing, Lee and Schwarz favor a grounded procedures perspective over recently developed disgust theory. We believe that this position stems from three errors: (1) interpreting cleansing effects as broader than they are; (2) not detailing the proximate mechanisms underlying disgust; and (3) not detailing adaptive function versus system byproducts when developing the grounded procedures perspective.

Abstract
Disgust has been consistently associated with greater political conservatism. Two explanations have been proposed for this link. According to a pathogen threat model, disgust serves a pathogen-avoidance function, encouraging more conservative ideology, whereas a sexual strategies model suggests that this link is explained by variability in short-term versus long-term mating goals. In two preregistered studies using a college student and community sample (total N = 1,950), we examined whether experimentally manipulating pathogen threat and mate availability produced differences in political ideology and whether these differences were explained by disgust and sociosexual attitudes. Across both studies, we did not find evidence that manipulating pathogen threat or mate availability resulted in change in political ideology. In Study 1, manipulating mate availability was indirectly associated with greater political conservativism through stronger sociosexual attitudes that favor monogamy. These findings failed to replicate in Study 2. Implications for theory and future research are discussed.

Abstract
Despite overwhelming evidence that vaccines are safe and effective, there has been a rise in vaccine hesitancy and refusal leading to increases in the incidence of communicable diseases. Importantly, providing scientific information about the benefits of vaccines has not been effective in counteracting anti-vaccination beliefs. Considering this, better identification of those likely to be vaccine hesitant and the underlying attitudes that predict these beliefs are needed to develop more effective strategies to combat anti-vaccination movements. Focusing on parents as the key decision makers in their children's vaccination, the aim of this study is to better understand the demographic and attitudinal predictors of parental vaccine hesitancy. We recruited 484 parents using Amazon MTurk and queried their attitudes on childhood vaccination, level of education, age, religiosity, political affiliation, trust in medicine, and disgust sensitivity. We found three main demographic predictors for parental vaccine hesitancy: younger age, lower levels of education, and greater religiosity. We also found vaccine hesitant parents to have significantly less trust in physicians and greater disgust sensitivity. These results provide a clearer picture of vaccine hesitant parents and suggest future directions for more targeted research and public health messaging.

Abstract
Researchers have proposed that intergroup prejudice is partially caused by behavioral immune system mechanisms. Across four studies (total N = 1,849), we used both experimental (pathogen priming) and individual differences (pathogen disgust sensitivity [PDS]) approaches to test whether the behavioral immune system influences prejudice toward immigrants indiscriminately (the generalized out-group prejudice hypothesis) or specifically toward immigrants from a pathogen-rich ecology (the origin-specific out-group prejudice hypothesis). Internal meta-analyses lend some support to both hypotheses. At the experimental level, pathogen primes had no effect on attitudes toward origin-unspecified immigrants or immigrants from a pathogen-rich ecology. At the individual differences level, PDS has a unique negative effect on comfort with immigrants from pathogen-rich ecologies but not on comfort with immigrants from unspecified ecologies. However, pathogen disgust sensitivity was negatively related to the decision to allow entry to both origin-unspecified immigrants and immigrants from a pathogen-rich ecology.
