This essay offers a philosophical analysis of the increased rates of hesitancy among Black Americans regarding treatment for Covid-19. I argue that public health researchers have identified epistemic norms pertaining to the credibility and trustworthiness of public health institutions in Black communities. In other words, norms of credibility have developed in Black communities as a result of the mistreatment of Black Americans by public health institutions and organizations. To make this argument, Section 2 argues that the “origin” or historical circumstances (...) regarding the emergence of an institution are salient to the formation of institutional trust. Section 3 develops an account of epistemic normativity as derived from the work of Antti Kauppinen, Miranda Fricker, and Catherine Elgin. Section 4 applies the arguments from the previous sections to show that absent a “clean origin,” norms of credibility regarding institutional functionality have formed in Black communities that have prevented medical treatment for Covid-19.
