12 pages., via online journal., Effective communication of risks involved in the climate change discussion is crucial and despite ambitious protection policies, the possibility of irreversible consequences actually occurring can only be diminished but never ruled out completely. We present a laboratory experiment that studies how residual risk of failure of climate change policies affects willingness to contribute to such policies. Despite prevailing views on people’s risk aversion, we found that contributions were higher at least in the final part of treatments including a residual risk. We interpret this as the product of a psychological process where residual risk puts participants into an ”alarm mode,” keeping their contributions high. We discuss the broad practical implications this might have on the real-world communication of climate change.
7 pages., via online journal., Pesticide use and pesticide residues in foods have been the subject of controversial public discussions and media coverage in Germany. Against this background, a better understanding of public risk perceptions is needed to promote efficient public health communication. To this end, this study captures the German public's perception of pesticide residues in foods. A representative sample of the population aged 14 years and older (n = 1,004) was surveyed via computer-assisted telephone interviewing on their attitudes and knowledge with regard to pesticide residues. Based on questions regarding their typical consumer behavior, respondents were classified into conventional and organic consumers to identify differences as well as similarities between these two consumer types. As assessed with an open-ended question, both organic and conventional consumers viewed pesticides, chemicals, and toxins as the greatest threats to food quality and safety. Evaluating the risks and benefits of pesticide use, more than two-thirds of organic consumers (70%) rated the risks as greater than the benefits, compared with just over one-half of conventional consumers (53%). Concern about the detection of pesticide residues in the food chain and bodily fluids was significantly higher among organic compared with conventional consumers. Only a minority of respondents was aware that legal limits for pesticide residues (referred to as maximum residue levels) exist, with 69% of organic and 61% of conventional consumers believing that the presence of pesticide residues in foods is generally not permitted. A lack of awareness of maximum residue levels was associated with heightened levels of concern about pesticide residues. Finally, general exposure to media reporting on pesticide residues was associated with more frequent knowledge of legal limits for pesticide residues, whereas actively seeking information on pesticide residues was not. The possible mechanisms underlying these findings are discussed.
12 pages., via online journal., Building on research in motivated reasoning and framing in science communication, we examine how messages that vary attribution of responsibility (human vs animal) and temporal orientation (now vs in the next 10 years) for wildlife disease risk influence individuals’ conservation intentions. We conducted a randomized experiment with a nationally representative sample of US adults (N = 355), which revealed that for people low in biospheric concern, messages that highlighted both human responsibility for and the imminent nature of the risk failed to enhance conservation intentions compared with messages highlighting animal responsibility. However, when messages highlighting human responsibility placed the risk in a temporally distal frame, conservation intentions increased among people low in biospheric concern. We assess the underlying mechanism of this effect and discuss the value of temporal framing in overcoming motivated skepticism to improve science communication.
11 pages., via online journal., Fish farmers need to take into account many factors, including climate-related risks, when making decisions to invest in stocking ponds or cages in rivers. Officials, experts, and other fish farmers try to influence these decisions by communicating information about risks verbally or using text messages. Recurrent mass mortality events associated with droughts and floods suggest some communication efforts have been ineffective. Theories of risk communication make different predictions about what elements make messages influential. The purpose of this study was to improve understanding of the potential influence of inserting tactical messages into a communication text on the decision behavior of fish farmers with respect to climate-related risks. Experiments were carried out on hand-held tablets with 1050 fish farmers as subjects. Fish farmers were asked to imagine they faced a risk of drought, water shortage, flood, or increasing risks of drought in a drying climate. They were also given a plausible response measure that would require some investment, and then asked to indicate how likely they would adopt that measure. Farmers’ intentions to take risk reduction actions in long-term adaptation increased when the message they received re-affirmed that they were susceptible to the threat, an impact was likely or that the response to the risk was an effective measure. For shorter-term risk reduction measures, the effect of re-affirming response efficacy was to suppress intentions to act. This study found no evidence that appeals to fear, guilt, or anxiety emotions work; references to social norms, behavioral control, and benefit versus cost arguments also failed to increase intentions to act. The findings of this study supported some propositions of common risk communication theories but not others. The methods and findings are useful for improving the design of communications aimed at informing farmers about climate-related risks.
11 pages., via online journal., The World Health Organization estimates that up to 30% of individuals in developed countries become ill from food or water each year. Up to 70% of these illnesses are estimated to be linked to food prepared at foodservice establishments. Consumer confidence in the safety of food prepared in restaurants is fragile, varying significantly from year to year, with many consumers attributing foodborne illness to foodservice. One of the key drivers of restaurant choice is consumer perception of the hygiene of a restaurant. Restaurant hygiene information is something consumers desire, and when available, may use to make dining decisions.
