The label of delusion can be so powerful that people so labelled are no longer believed or supported in preferred ways by those around them. This leads to a lack of meaningful and non-pathologising support for their significant, and at times unusual, beliefs. This phenomenon constitutes a form of epistemic injustice. To address this issue, this paper outlines specific approaches practitioners can adopt to better respond to such beliefs, illustrating these strategies with real-world examples from practice. By doing so, it aims to foster a form of epistemic justice that respects the knowledge and experience of people labelled as delusional and supports them to understand and lessen the impact of these often-distressing experiences. This paper is informed by research undertaken with people who had been labelled by psychiatry as “delusional”.
