Recent philosophical literature on epistemic harms has paid little attention to the difference between deliberate and non-deliberate harms. In this paper, I analyze the “Curare Case,” a case from the 1940’s in which patient testimony was disregarded by physicians. This case has been described as an instance of epistemic injustice. I problematize this description, arguing instead that the case shows an instance of “epistemic disadvantage.” I propose epistemic disadvantage indicates when harms result from warranted asymmetric relations that justifiably exclude individuals from hermeneutical participation. Epistemic disadvantage categorizes harms that result from justifiable exclusions, are non-deliberate, and result from poor epistemic environments. This analysis brings out a meaningful difference between accidental and deliberate harms in communicative exchanges.
