Jon Williamson

Jon Williamson is the Prof Samuel Hall Chair of Philosophy at the University of Manchester. His work spans philosophy of science, medicine, AI, law, epistemology, metaphysics, and logic, with a focus on causality, probability foundations, and formal epistemology. He leads interdisciplinary projects like EBL+ (Evidence-Based Law) and EBM+ (Evidence-Based Medicine), advocating Evidential Pluralism to integrate diverse evidence types in causal reasoning across disciplines.

• Research Interests: Causality, formal epistemology, evidence integration, mechanism-based reasoning, and applications in law/policy.
• Key Projects: Interdisciplinary Systematic Review (UKRI-funded), EBL+ (Leverhulme Trust-funded), and EBM+ initiatives.
• Contributions: Co-authored Evidential Pluralism in the Social Sciences (Routledge, 2023) and developed frameworks for evidence-based policy evaluation.

His research emphasizes rigorous causal enquiry across domains, including law, healthcare, and social sciences. Recent work addresses epistemic justice in evidence evaluation and the role of mechanisms in policy design. Williamson actively organizes seminars and collaborates internationally on causal inference methodologies.
