Abstract
The idea of conducting upstream public engagement over emerging technologies has been gaining popularity in Europe and North America, with nanotechnologies seen as a test case for this. For many of its advocates, upstream engagement is about a re-conceptualisation of the science–society relationship in which a variety of ‘publics’ are brought together with stakeholders and scientists early in the Research and Development process to co-develop technological trajectories. However, the concept, aims and processes of upstream engagement remain ill-defined, are often misunderstood, and have undergone little critical analysis. This special issue of NanoEthics, entitled ‘Engaging with Nanotechnologies–Engaging Differently?’ takes a multi-nation, multi-case approach to explore this idea, drawing on work represented by four articles from the US and Europe, from ethnographic work in the nanotechnology lab through to analysis of a Citizens’ Jury and other attempts to move public debate ‘upstream’. An overall message from the papers is that without adequate critique ‘upstream engagement’ might end up re-producing out-dated forms of science communication or being rejected as a failed concept before it has even matured.
