Pathogen Prevalence, Group Bias, and Collectivism in the Standard Cross-Cultural Sample

Cashdan, Elizabeth, Steele, Matthew·2013·Human Nature

Abstract

It has been argued that people in areas with high pathogen loads will be more likely to avoid outsiders, to be biased in favor of in-groups, and to hold collectivist and conformist values. Cross-national studies have supported these predictions. In this paper we provide new pathogen codes for the 186 cultures of the Standard Cross-Cultural Sample and use them, together with existing pathogen and ethnographic data, to try to replicate these cross-national findings. In support of the theory, we found that cultures in high pathogen areas were more likely to socialize children toward collectivist values (obedience rather than self-reliance). There was some evidence that pathogens were associated with reduced adult dispersal. However, we found no evidence of an association between pathogens and our measures of group bias (in-group loyalty and xenophobia) or intergroup contact.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In countries and cultures with historically higher parasite prevalence, people are less individualistic, exhibit lower openness, are more likely to conform, and more strongly endorse binding moral values.

    “in countries and cultures characterized by historically higher prevalence of parasitic diseases, people are less individualistic, exhibit lower levels of dispositional openness to new things, are more likely to conform to majority opinion, and more strongly endorse “binding” moral values that emphasize group loyalty, obedience, and respect for authority [15], [16], [17], [18], [19].”
  • The Cashdan and Steele measure of historical pathogen prevalence was internally reliable, with Cronbach's alpha = .81.

    “This measure was internally reliable, Cronbach’s alpha = .81.”
  • Cashdan and Steele's results provided important substantiation for the relationship between disease prevalence and collectivist values, especially adherence to group norms.

    “their results provided important substantiation for the relationship between disease prevalence and collectivist values—especially those values pertaining to adherence to group norms.”
  • The two parasite prevalence indices (Cashdan and Steele and Low) are highly correlated, r = .87 (p<.001).

    “These two indices [15], [36] are highly correlated, r = .87 (p<.001).”
  • Pathogen prevalence uniquely predicted 11 of the 12 individual variables comprising the authoritarian governance index.

    “Results are summarized in Table 3, and reveal that pathogen prevalence uniquely predicted 11 of the 12 variables: Higher levels of pathogen prevalence were associated with ethnographic observations indicating more authoritarian systems of governance.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
