Local Issue Severity and Ideological Worldviews: Motivated Reasoning in the Case of Water Scarcity.

Studies linking local issue severity to public opinion often treat the effect as homogeneous, suggesting a straightforward relationship between issue exposure and policy opinions. It is more likely that individuals perceive local issues in conditional ways. We advance a theory of motivated reasoning whereby beliefs and worldviews act as a lens through which individuals interpret the world around them. When a local issue conforms to individuals' prior beliefs, they will be even more likely to perceive risk and call for policy action. When the information presented to them is incongruent with their worldview, increasing issue severity will have a minimal effect. We test our theory by combining an indicator of water scarcity with data from two national public opinion surveys about water issues. Using OLS regression to analyze interactive models predicting risk perception and policy preferences, we find that water scarcity drives individuals with opposing ecological worldviews even further apart.
