This paper considers the implications of construal level theory in the context of survey experiments probing foreign policy opinion formation. Psychology research demonstrates that people discount the long-term consequences of decisions, thinking about distal or hypothetical events more abstractly than immediate scenarios. I argue that this tendency introduces a bias into survey experiments on foreign policy opinion. Respondents reasoning about an impending military engagement are likelier to consider its costs than are those reasoning in the abstract hypothetical environment. I provide evidence of this bias by replicating a common audience costs experimental design and introducing a prompt to consider casualties. I find that priming respondents to articulate their expectations about casualties in a foreign intervention reduces support and dampens the experimental effect, thereby cutting the estimated absolute audience cost substantially. This result suggests a gap between how survey respondents approach hypothetical and real situations of military intervention.
I would like to thank Nicholas Weller for his tireless help, extensive brainstorming, and numerous read-throughs in developing this project. I also appreciate the helpful comments from Patrick James, Youssef Chouhoud, Tom Jamieson, and all the participants in the University of Southern California's Center for International Studies’ working paper series. I also greatly appreciate the grant provided by USC-CIS to carry out the experiment.
