Emerging nanotechnologies pose a new set of challenges for researchers, governments, industries and citizen organizations that aim to develop effective modes of deliberation and risk communication early in the research and development process. These challenges derive from a number of issues including the wide range of materials and devices covered by the term 'nanotechnology', the many different industrial sectors involved, the fact that many areas of nanotechnology are still at a relatively early stage of development, and uncertainty about the environmental, health and safety impacts of nanomaterials. Public surveys have found that people in the United States and Europe currently view the benefits of nanotechnologies as outweighing their risks although, overall, knowledge about nanotechnology remains very low. However, surveys cannot easily uncover the ways that people will interpret and understand the complexities of nanotechnologies (or any other topic about which they know very little) when asked to deliberate about it in more depth, so new approaches to engaging the public are needed. Here, we report the results of the first comparative United States-United Kingdom public engagement experiment. Based upon four concurrent half-day workshops debating energy and health nanotechnologies we find commonalities that were unexpected given the different risk regulatory histories in the two countries. Participants focused on benefits rather than risks and, in general, had a high regard for science and technology. Application context was much more salient than nation as a source of difference, with energy applications viewed in a substantially more positive light than applications in health and human enhancement in both countries. More subtle differences were present in views about the equitable distribution of benefits, corporate and governmental trustworthiness, the risks to realizing benefits, and in consumerist attitudes.
In response to the impetus that is gathering in the UK for upstream public engagement, we analyze the impacts of the Royal Society and Royal Academy of Engineering report of 2004 on Nanoscience and Nanotechnologies: Opportunities and Uncertainties. The paper presents an analysis of 24 interviews with stakeholders to the nanotechnology debate. It uses these to discuss the inquiry process and the recommendations contained within the report, as well as to explore and critique the notion of “upstream.” We find broad support for the inquiry, which was positioned by many stakeholders itself as upstream, primarily because of its broad framing and wide stakeholder involvement. A number of both explicit and implicit upstream elements are also contained within its recommendations. However, the interviews also suggest that the notion of upstream engagement is a contested concept with a range of associated dilemmas and tensions. In drawing out some of the promise and perils of moving public debate upstream, the paper concludes that there is a risk of merely replacing the perceived deficit in public understanding of science with a perceived deficit in public engagement with science
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
