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.
16 pages., via online journal., The 2018 report from the Intergovernmental Panel on Climate Change warns that Earth’s temperatures may soon reach a tipping point that threatens humanity’s future. Scientists from many disciplines agree that anthropogenic climate change is a serious problem yet many Americans remain skeptical of the existence, causes, and/or severity of climate change. In this article, we review recent research on climate change communication focusing on audience variables and messaging strategies with the goal of providing communication practitioners research-based recommendations for climate change message design. Factors that influence audience acceptance and understanding of climate science include: demographic variables (such as political party affiliation, religious orientation, and geographic location), as well as brief sections on misinformation, and beliefs in pseudoscience. Keys to effectively construct climate messaging are discussed including: framing strategies; reducing psychological distance; emotional appeals; efficacy cues; weight-of-evidence/ weight of expert reporting; inoculation/correcting misinformation; and separating science from conspiracy theories. Evidence-based strategies are critical in giving science communicators the tools they need to bridge the gap between the scientific community and the at-risk public.

14 pages, via online journal, Research on the gateway belief model indicates that communicating the scientific consensus on global warming acts as a “gateway” to other beliefs and support for action. We test whether a video conveying the scientific consensus on global warming is more effective than a text transcript with the same information. Results show that the video was significantly more effective than the transcript in increasing people’s perception of scientific agreement. Structural equation models indicate indirect increases in the beliefs that global warming is happening and is human-caused, and in worry about global warming, which in turn predict increased global warming issue priority.
