This conference is part of the Marie Skłodowska-Curie 'ReaDoubt' project, which examines reasoning and decision-making under uncertainty through the lens of the notion of 'reasonable doubt', taken both as a legal standard of proof, and as a potential norm of reasoning and decision-making more generally.

The conference will bring together scholars from various disciplines (epistemology, psychology, law, statistics) and practicing professionals (lawyers/judges, clinicians, climate scientists, forensic scientists, journalists) concerned with the 'reasonableness' of doubt. The goal is not only to encourage interdisciplinary dialogue, but also to pay particular attention to everyday practice.


This should shed new light on epistemological and psychological questions about the nature and dynamics of belief and action, as well as on difficult judicial issues. Fostering such a dialogue among disciplines, and between researchers and practitioners, should also have implications for currently pressing societal issues such as the role and credentials of experts in democracy, conspiracy theories, science denial, and the epistemology and psychology of the social media — in short, societal concerns rooted in the difficulty of navigating an overwhelming mass of information.

The programme includes keynote papers, contributed papers, as well as a roundtable bringing together practitioners in different domains.
