Experts More Worried about Nanotech than Public



My colleague Dietram Scheufele is lead author on a study in the latest issue of Nature Nanotechnology. In their survey work, Scheufele et al. find that experts are more concerned about the health and environmental risks of nanotech than the public at large. This gulf in perceptions is despite a widespread lack of knowledge about the issue among citizens. See the press release.

The findings are consistent with a study I published earlier this year with another University of Wisconsin colleague Dominique Brossard. In our survey analysis examining American perceptions of plant biotechnology, we describe as a strong value construct in American culture the tendency to automatically defer to scientific authority and expertise.

On most issues, most of the time, the preferred heuristic for the public is to trust scientists and government regulators. In other words, absent any cues that an emerging area of science might conflict with a rival value system such as religion or environmentalism, the public for the most part prefers not to know much about the risks or benefits of a technology. All that is needed is for scientists and regulators to reassure the public that a product is safe.

With nanotechnology, at this stage in its mediated issue development, no news is good news. Nanotech remains covered at the science and business pages and has yet to spill over into the wider public eye. Moreover, this limited amount of coverage remains strongly framed in terms of social progress and economic development.

However as I note with Scheufele in our article at The Scientist there are signs of a possible emerging frame shift. Yet until competing elites start to actively frame the issue in terms that trigger the application of values other than a default deference to science, expect the public to remain blissfully ignorant and supportive of nanotech.

Mind & Brain
  • The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
  • Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
  • Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
