["Health Expectations, Volume 29, Issue 2, April 2026. ", "\nABSTRACT\n\nBackground\nCo‐production research values the lived/living experience (LE) of people navigating health challenges. Despite this, traditional academic authorship often disregards power dynamics that participatory research seeks to address.\n\n\nMain Body\nThis critical reflection argues for centring LE collaborators as first authors in co‐production research. We analyse authorship through Foucauldian power/knowledge dynamics, Derrida's deconstructive ethics and Levinasian ethics of responsibility, drawing on Critchley's synthesis of these traditions. This multiple lens reveals a tension: co‐production research requires political solidarity (‘us’) to challenge epistemic injustice, yet demands ethical vigilance to preserve individual voices. The concept of porous solidarity is useful here. Acknowledging the value of experience‐based expertise by means of first authorship embodies this framework: it redistributes epistemic authority and shifts research from studies about populations to studies by/with those populations.\n\n\nConclusions\nFirst author placement of experience‐based experts where appropriate, plus explicit acknowledgement of all researchers' relevant LE where freely given, offers both an ethically responsive approach and a practical strategy for aligning co‐production processes with publication practices. By centring LE collaborators as first authors and acknowledging the LE of academic researchers, co‐production research teams can embody the principle rooted in disability activism, of ‘nothing about us without us—leading’ in academic literature. This supports epistemic justice, creates solidarity and builds capacity within communities conducting research.\n\n\nPatient or Public Contribution\nThis lived experience–led article was co‐produced by two researchers with lived experience. Experiential expertise shaped the conception, argument development, drafting and critical revision of the manuscript and the practical implications presented.\n"]
