Advocating a New Approach to Governing Water, Energy, and Food Security: Testing the Effects of Message Inoculation and Conclusion Explicitness in the Case of the WEF Nexus

Abstract

Message sidedness, including its later format inoculation, and conclusion explicitness have been identifi ed by researchers as two prominent message factors that may infl uence advocating eff ects. Two-sided messages, which contain both supporting and opposing information about the issue, particularly those containing inoculation components that refute the negative side, are found to be more eff ective than one-sided messages. Messages with explicit conclusions are also found to be more persuasive than those that let the audience draw the conclusions themselves. This study tested the persuasion eff ectiveness of message inoculation and conclusion explicitness on a new scientifi c concept, the water–energy–food (WEF) nexus, of which the public has little knowledge. This study used fi ve randomly assigned groups (total N = 524) and found that messages with explicit conclusions are more persuasive than those with implicit conclusions; however, it found no diff erence between the eff ectiveness of one-sided messages and of refutational two-sided
messages. The study suggests that a clear conclusion is necessary to communicate the WEF nexus for a better approach to managing the megacrisis of water, energy, and food security.
