Framing effects on public opinion about nanotechnology

In this study, I examine whether Americans' emotions and opinions about nanotechnology are influenced by how the issue is framed. Using data collected from an experiment embedded within a national survey, I find consistent framing effects even though the magnitudes of respondents' opinion changes are not especially large. Frames about specific risks and benefits of nanotechnology are more influential than frames based on general beliefs about the merits of science, and framing nanotechnology as beneficial is only, somewhat less powerful than framing it as risky. I conclude by discussing the implications of these framing effects for future mass opinions about nanotechnology.
