Abstract: Recent work in social and feminist epistemology has emphasized the importance of first-person testimony. But its sometimes unclear when and to what extent we are obligated to believe people’s testimony about their own experiences. I use Katherine Hawley’s framework of trust and trustworthiness to explore a particular example: the case of medical gaslighting and testimonial injustice in healthcare contexts. I argue that Hawley’s framework can help to illuminate places where concepts like ‘gaslighting’ and ‘testimonial injustice’ might be over-extended.
