Blood libels are narratives about Jews and Christians, featuring an accusation that a child or a woman had been kidnapped and assaulted due to religious or economic goals. Blood libel-like narratives, however, are not only found in Judeo-Christian history; they appear in many cultures. Using the framework of Cultural Attraction Theory, the paper considers their evolution, and identifies testable factors of attraction. The paper makes two claims regarding the morphology and the function of these ancient tales. Firstly, narratives about outgroups tend to evolve towards the shape of a blood libel, as it taps into an optimum number of universal cognitive preferences. The correspondence with the evolved features of the mind contributes to the success of the narrative in different cultures and time periods. Secondly, these narratives function as coalition signals. Upon calling ingroup members into action against an outgroup, the blood libel unifies audiences before engaging in exclusionary action.

Can people efficiently navigate the modern communication environment, and if yes, how? We hypothesize that in addition to psychological capacities of epistemic vigilance, which evaluate the epistemic value of communicated information, some social institutions have evolved for the same function. Certain newspapers for instance, implement processes, distributed among several experts and tools, whose function is to curate information. We analyze how information curation is done at the institutional level and what challenges it meets. We also investigate what factors favor the cultural evolution of institutions of epistemic vigilance: these include people’s preference for accurate and reliable information and their ability to assess communicated information in view of the source’s epistemic authority; but also contingent historical factors that make it worth—or not—to contribute to the maintenance of institutions of epistemic vigilance. We conclude the paper by considering the challenges and vulnerabilities of these institutions in the Digital Age.
