I explain the notion of contributory injustice, a kind of epistemic injustice, and argue that it occurs within psychiatric services, affecting those who hear voices. I argue that individual effort on the part of clinicians to avoid perpetrating this injustice is an insufficient response to the problem; mitigating the injustice will require open and meaningful dialogue between clinicians and service user organisations, as well as individuals. I suggest that clinicians must become familiar with and take seriously concepts and frameworks for (...) understanding mental distress developed in service user communities, such as Hearing Voices Network, and by individual service users. This is especially necessary when these concepts and frameworks explicitly conflict with medical or technical understandings of users’ experiences. I defend this proposal against three objections.
