We propose and study the concept of survey rationalizability, that we base on classical item response theories in psychology. Survey rationalizability involves positioning survey questions on a common scale such that, in the main case of attitudinal surveys, each respondent gives higher support to questions that are more aligned with her views. We first demonstrate that ideas from standard revealed preference analysis can be used to characterize when and how dichotomous surveys are rationalizable. We then show that these results readily extend to more general surveys. Furthermore, we investigate the identification of the models and extend the analysis in several directions.
