2017 Annual Symposium of the Applied Social Science Group at the Primary Care Unit. Refreshments for all served from 13.45

Dr John’s talk will be chaired by Professor Sir David Spiegelhalter, Winton Professor of the Public Understanding of Risk, University of Cambridge.

Any claim about an individual’s risk of harm is always made relative to some reference class (or body-of-information): there is no such thing as an individual’s “actual” risk of lung cancer, but, rather, his risk “as a smoker” or “as a 40 year old”. This familiar claim in the philosophy of statistics gives rise to a simple question: which risk estimate should physicians communicate to individuals in the clinic? In this paper, I explain why this question is so difficult; I\argue that some standard ways of addressing it in the medical literature are deeply unethical; and I investigate the relationship between my question and the more familiar question of how we should present risk information.

Dr Alexandra Freeman, Executive Director, Winton Centre for Risk and Evidence Communication, and Dr Juliet Usher-Smith, Clinical Senior Research Associate, Primary Care Unit, University of Cambridge, will respond to Dr John’s talk.

This talk is part of the Primary Care series.
