- Notes:
- 19 pages., via online journal., The impact of knowledge on public attitudes toward scientific issues remains unclear, due in part to ill-defined differences in how research designs conceptualize knowledge. Using genetically modified foods as a framework, we explore the impacts of perceived familiarity and factual knowledge, and the moderating roles of media attention and a food-specific attitudinal variable (food consciousness), in shaping these relationships. Based on the differential effects on “negative attitudes” toward genetically modified foods, we provide further evidence that the measures of knowledge are separate concepts and argue against a one-dimensional view of scientific knowledge. We discuss implications for understanding the relationship between knowledge and science attitudes.

- Notes:
- 21 pages., via online journal., Scholars are divided over whether communicating to the public the existence of scientific consensus on an issue influences public acceptance of the conclusions represented by that consensus. Here, we examine the influence of four messages on perception and acceptance of the scientific consensus on the safety of genetically modified organisms (GMOs): two messages supporting the idea that there is a consensus that GMOs are safe for human consumption and two questioning that such a consensus exists. We found that although participants concluded that the pro-consensus messages made stronger arguments and were likely to be more representative of the scientific community’s attitudes, those messages did not abate participants’ concern about GMOs. In fact, people’s premanipulation attitudes toward GMOs were the strongest predictor of of our outcome variables (i.e. perceived argument strength, post-message GMO concern, perception of what percent of scientists agree). Thus, the results of this study do not support the hypothesis that consensus messaging changes the public’s hearts and minds, and provide more support, instead, for the strong role of motivated reasoning.
4. Science - especially climate research - needs a "sunshine" law

- Notes:
- Online from Radio Free. 3 pages., Author reports on helping the U.S. Senate draft and pass the Physician Payments Sunshine Act a decade ago. It requires companies to report monies and gifts they give physicians, which are known to influence what doctors prescribe or promote. "We need a 'sunshine law' for science that would expose all sorts of conflicts of interest and industry manipulation that skew research on food, synthetical chemicals, pesticides, air pollution, genetic technology, and the climate."
