Deference to scientific authority among a low information public: Understanding US Opinion on agricultural biotechnology

This study uses the contemporary debate over agricultural biotechnology to conceptualize a theoretical model that can be used to explain how citizens reach judgments across a range of science and technology controversies. We report findings from a mail survey of New York State residents that depicts a 'low information' public relying heavily on heuristics such as value predispositions, trust, and schema to form an opinion about agricultural biotechnology. Science knowledge does play a modest role, with the news media serving as an important source of informal learning. Contrary to expectations and past research, we do not find any direct effects for news attention on support for agricultural biotechnology. Deference to scientific authority is a central value predisposition shaping support for agricultural biotechnology. Positively correlated with education, deference to scientific authority is the strongest influence on support for agricultural biotechnology in our model. Part of the variable's influence is direct, but part of it is also indirect, as deference to scientific authority is a key predictor of both trust in the sponsors of biotechnology and generalized reservations about the impacts of science.
