Something of a long read on the blog today. I first came across Jerome Ravetz’s work in his 2011 piece on feral futures co-written with Rafael Ramírez in the journal Futures. In that piece, the authors argue that complex, uncertain issues such as environmental disasters can be made worse by conventional risk-based thinking. I think through some of the ways in which this is important for us to consider in 2020 in this blog, “Our feral future: working on the crises you did(n’t) see coming.“
I find Ravetz’s approach thought-provoking, pragmatic, and deeply relevant to the present moment. It attends to questions of uncertainty and emphasises that science itself is situated within complex social, political, cultural, and economic contexts. Especially when we find ourselves being told that, for example, decisions on quarantine and lockdown measures are being “guided by the science” under contested circumstances, it’s worth getting your head around the idea of “post-normal science.”
Today, I want to go through some of the key points articulated in Ravetz’s 2006 No-Nonsense Guide to Science and the updated 2020 version of his landmark 1993 essay with Silvio O. Funtowicz, “Science for the Post-Normal Age“. Check those texts out, if you want to go deeper.
Post-normal science is a way of rethinking science for situations – and eras – in which facts are uncertain, values are in dispute, the stakes are high, and decisions are urgent. It recognises that the social and political dimensions of science cannot be sidelined, isolated, or ignored.
The increasingly complex systems of today’s world are threatened by environmental catastrophe, pollution, and other incidents, like the COVID-19 outbreak, which are exacerbated by the technologies sustaining our way of life.
Science must therefore find new ways to cope with contradiction, uncertainty, and an ever-wider political conversation featuring a wide range of perspectives. It must now address the problems of a global system which itself was based on science.
