In this paper, we confront two prevailing views of rationality—reason- and coherence-based theories—with empirical facts. While the experimental resolution of the debate between both theories is challenging, we examine two cases in which these theories make distinct predictions regarding whether an agent is deemed rational or not. By directly pitting reason-based against coherence-based theories, our findings indicate that reasons play a more influential role in shaping people's attributions of rationality than coherence.
