What is risk?

A new book from Cambridge University Press – Successful Science communication, (Bennett and Jennings eds.) – contains 26 chapters with helpful things to say to people concerned to communicate complex ideas to “the public”. Plus a chapter by me entitled Not 100% sure? The public” understanding of risk; the reader is left to judge whether it too is helpful.

It begins: Where knowledge (belief) relates to potential future harms or benefits, as it usually does in situations where science communication is seen as problematic or contentious, the issue can be framed as one of risk communication.

And concludes: The problem for science communicators is that we, scientist and non-scientist alike, do not respond blankly to uncertainty. We impose meaning upon it. The greater the uncertainty the greater becomes the influence of perceptual biases. These biases have deep cosmological roots and are not easily shifted. Perhaps the best that a science communicator can hope for is that introspection might assist recognition of ones own biases, and an awareness of the inevitability of different biases in others. Self-knowledge and an ability to stand metaphorically in the shoes of others are key ingredients of the empathy essential to effective communication.
