The article addresses ongoing debates in the study of political knowledge and voting behavior. The article identifies significant divergences in previous work which may explain why such debates persist, including in the measurement of political knowledge and the inclusion of confounding variables. The article remedies these issues in an observational study examining how political knowledge affects the impact of spatial considerations and cognitive shortcuts on the vote. The article also contributes the first randomized experiment on this research question in the literature. Using the framework of conjoint analysis, the experiment evaluates how political knowledge affects the impact of spatial considerations and cognitive shortcuts on the vote. The article hypothesizes that political knowledge will increase the impact of spatial considerations on the vote but will not modify the impact of cognitive shortcuts. This expectation is supported in both the observational and experimental results.
