Great, great paper on the influence of psychological states of uncertainty on people’s decision making (“Uncertainty Increases the Reliance on Affect in Decisions”, Faraji-Rad, A.; & Pham, M. T. (2017), Journal of Consumer Research, 44 (1): 1-21). In a nutshell: Under uncertainty, people rely on affect/emotions. Relevant for social marketers and/or behavioral designers dealing with issues such as climate change and health prevention.
