- First formal application of Fricker's epistemic injustice framework to CFS/ME.
- Doctors display uncertainty about whether CFS/ME is real, resulting in diagnostic/treatment delays.
- Patients experience suspicion from healthcare professionals about their testimony.
- Patients vocally oppose the effectiveness and conceptualization of their illness as psychologically treatable.

- Strategic similarities between UK ME/CFS POs and 1980s US AIDS activist organizations: public activism + scientific publications.
- Widespread negative stereotyping of patients and marginalization of patient voices by medical authorities better explains expressions of frustration.
- Draws on concept of epistemic injustice to explain the discourse.Relevance:: Directly addresses the contested legitimacy of patient advocacy. Counter-narrative to “difficult patient” trope.

- Patient representatives in the 2013--2018 Dutch ME/CFS Health Council advisory process predominantly offered biomedical knowledge.
- They framed ME/CFS as primarily somatic and perceived appropriate evidence as quantifiable, objectifiable, and explicitly non-psychogenic.
- Biomedicalized patient participation enhances credibility but may also undermine non-biomedical patient knowledge.
- Risk of sustaining biased and reductive ideas about who ill people are and what kind of knowledge they hold.Relevance:: Offers important complexity to the participatory narrative: patient participation can itself be co-opted into reductive biomedical framing.
