What do we mean by knowledge controversies?
The GM saga signalled a sea-change in social attitudes towards the place of science in public policy-making, with scientific work once hidden in labs and journals subjected to intense public scrutiny and debate.

Scientists and policy makers are actively reviewing their working practices and thinking again about how science does, and should, inform democratic decision-making.
Unprecedented attention is being paid to how to cope with scientific uncertainty and regain public confidence in the knowledge claims and technologies that inform policy.
