Determinants of hyena participation in risky collective action.

ABSTRACT: Collective action problems arise when cooperating individuals suffer costs of cooperation, while the benefits of cooperation are received by both cooperators and defectors. We address this problem using data from spotted hyenas fighting with lions. Lions are much larger and kill many hyenas, so these fights require cooperative mobbing by hyenas for them to succeed. We identify factors that predict when hyena groups engage in cooperative fights with lions, which individuals choose to participate and how the benefits of victory are distributed among cooperators and non-cooperators. We find that cooperative mobbing is better predicted by lower costs (no male lions, more hyenas) than higher benefits (need for food). Individual participation is facilitated by social factors, both over the long term (close kin, social bond strength) and the short term (greeting interactions prior to cooperation). Finally, we find some direct benefits of participation: after cooperation, participants were more likely to feed at contested carcasses than non-participants. Overall, these results are consistent with the hypothesis that, when animals face dangerous cooperative dilemmas, selection favours flexible strategies that are sensitive to dynamic factors emerging over multiple time scales.

Project description:Background: A growing number of global health interventions involve community members in activism to prevent violence against women (VAW), but the psychological drivers of participation are presently ill-understood. We developed a new scale for measuring three proposed drivers of participation in collective action to address VAW in the context of urban informal settlements in Mumbai, India: perceived legitimacy, perceived efficacy, and collective action norms. Methods: We did a household survey of 1307 men, 1331 women, and 4 trans persons. We checked for 1) social desirability bias by comparing responses to self-administered and face-to-face interviews, 2) acquiescence bias by comparing responses to positive and negatively worded items on the same construct, 3) factor structure using confirmatory factor analysis, and 4) convergent validity by examining associations between construct scores and participation in groups to address VAW and intent to intervene in case of VAW. Results: Of the ten items, seven showed less than five percentage point difference in agreement rates between self-administered and face-to-face conditions. Correlations between opposite worded items on the same construct were negative (p<0.05), while correlations between similarly worded items were positive (p<0.001). A hierarchical factor structure showed adequate fit (Tucker-Lewis index, 0.920; root mean square error of approximation, 0.035; weighted root mean square residual, 1.952). Perceived legitimacy, efficacy and collective action norms all predicted participation in groups to address VAW and intent to intervene in case of VAW, even after adjusting for social capital (p<0.05). Conclusion: This is the first study to operationalize a measure of the psychological drivers of participation in collective action to address VAW in a low- and middle-income context. Our novel scale may provide insight into modifiable beliefs and attitudes community mobilisation interventions can address to inspire activism in similar low-resource contexts.
