Science to the rescue or contingent progress? Comparing 10 years of public, expert and policy discourses on new and emerging science and technology in the United Kingdom.

Over the past 10 years, numerous public debates on new and emerging science and technologies have taken place in the United Kingdom. In this article, we characterise the discourses emerging from these debates and compare them to the discourses in analogous expert scientific and policy reports. We find that while the public is broadly supportive of new scientific developments, they see the risks and social and ethical issues associated with them as unpredictable but inherent parts of the developments. In contrast, the scientific experts and policymakers see risks and social and ethical issues as manageable and quantifiable with more research and knowledge. We argue that these differences amount to two different sociotechnical imaginaries or views of science and how it shapes our world - an elite imaginary of 'science to the rescue' shared by scientists and policymakers and public counter-imaginary of 'contingent progress'. We argue that these two imaginaries indicate that, but also help explain why, public dialogue has had limited impact on public policy.
