Science Communication and the Rationality of Public Opinion Formation

Abstract

Because research indicates that people’s value orientations significantly affect their opinions about advanced technologies some risk scholars argue that technology policy should reflect the recommendations of experts rather than the opinions of a value-driven public. This suggested approach might be bolstered to the extent that people use substantive (value-driven) rather than formal (reason-driven) rationality when assessing the recommendations of experts. We found evidence that people’s opinions are indeed influenced strongly by their substantive rationality. We nevertheless argue that technology policy formation should rely more rather than less upon public opinions, thereby encouraging further efforts at improving science communication theory and practice.
