My colleague Jess Whittlestone and I spoke with Prof David Spiegelhalter, the Winton Professor of the Public Understanding of Risk at the University of Cambridge.
Prof Spiegelhalter tries to help people prioritise and respond to the many hazards we face, like getting cancer or dying in a car crash. To make the vagaries of life more intuitive he has had to invent concepts like the microlife, or a 30-minute change in life expectancy. He’s regularly in the UK media explaining the numbers that appear in the news, trying to assist both ordinary people and politicians to make sensible decisions based in the best evidence available.
We wanted to learn whether he thought a lifetime of work communicating science had actually had much impact on the world, and what advice he might have for people planning their careers today.

“…What do we hear in the news? We hear about Ebola, we hear about terrorism, we hear about the latest threat that might be in what we eat and the way we travel, and we get very concerned about this, whether it’s a plane crash or whatever. Because that’s what’s in the news, that’s what is available to us. That’s what’s so prominent, but of course, so many of these risks are actually very small indeed…
What I am proud of is being part of a general community that’s very strong in Britain, to do with public engagement in science, which I’m just a small part of that because it covers material on the radio, stuff on television, stuff in some newspapers, and in various agencies. For example, in Statistics Authority, which is just trying to take a much more critical attitude to the way that numbers and evidence are used in society. I think it works. In Britain, we’re rather good compared with most people about, I don’t know, we don’t have these massive fears of vaccinations and nuclear power, of even GMOs. I think this is a sign that we in this country have developed quite a good public engagement with science community.”
