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.

27 pages, via online journal, This study explored whether satire (an emotional blend of humor/indignation) can minimize the emotional tradeoffs researchers have documented for humorous appeals about climate change. Using a sample of U.S. young adults, we conducted a 2 (humor: present/absent) × 2 (indignation: present/absent) + 1 (control) experiment in which we manipulated a climate change segment from Jimmy Kimmel Live! Our evidence suggests that it is possible for a late-night host to affect young adults’ climate change risk perception and behavioral intentions under certain conditions. Moderation analyses indicated that avoiding humor helped close the partisan gap in risk perception between Republicans and Democrats.

Notes:
30 pages., Online via website., "Despite the growing use of genetically modified crops over the past 20 years, most Americans say they know only a little about GM foods. And many people appear to hold 'soft' views about the health effects of GM foods, saying they are not sure about whether such foods are better or worse for one's health. ... a majority of Americans perceive disagreement in the scientific community over whether or not GM foods are safe to eat. And, only a minority of Americans perceive scientists as having a strong understanding of the health risks and benefits of GM foods."
