Abstract: Input from scientific experts and lay audiences plays an important role in the realization of scientific advances and scientific policymaking. This study examines factors influencing expert and public attitudes toward the regulation of academic and commercial nanotechnology. Compared to scientific experts, lay publics are more likely to support the regulation of academic nanotechnology, with value predispositions playing a critical role in impacting such opinions. Among lay audiences, liberals and respondents reporting higher levels of religiosity were more likely to support regulation of both academic and commercial nanotechnology research, while those who paid greater attention to the media were more supportive of regulations for commercial research. Across the two groups, perceptions of risks relative to benefits consistently predicted attitudes toward regulation. Importantly, scientists rely less upon their value predispositions when forming regulatory attitudes, instead basing such attitudes on perceptions of regulatory impacts on scientific progress. The regulatory implications of these findings are discussed.
