Department of Statistics public lecture
Date: Wednesday 17 November 2010
Venue: Hong Kong Theatre, Clement House
Speaker: Professor David Spiegelhalter
Chair: Professor Anthony C Atkinson
There has been a traditional division between 'risk', which can be quantified using probability distributions, and 'uncertainty', which is the surrounding mess of doubt, disagreement and ignorance. In well-understood situations we may be happy to quote reasonable odds for future events, and I shall look at ways in which these risks can be communicated visually. When the problem is more complex, analysts may use a mixture of judgement and historical data to construct a mathematical model that can assess future risks, but deeper uncertainties may be glossed over. I will use examples from swine flu to climate change to illustrate different approaches to dealing with uncertainty, from ignoring it to trying to fully quantify it, and conclude that we should all try to be aware and open about the magnitude and potential consequences of our ignorance.
David Spiegelhalter is Winton Professor of the Public Understanding of Risk at the University of Cambridge as well as senior scientist in the MRC Biostatistics Unit.
Professor Anthony C Atkinson is Professor of Statistics at the Department of Statistics at LSE.
