In this article, I argue for four theses. First, libertarian and compatibilist accounts of moral responsibility agree that the capability of practical reason is the central feature of moral responsibility. Second, this viewpoint leads to a reasons-focused account of human behavior. Examples of human action discussed in debates about moral responsibility suggest that typical human actions are driven primarily by the agent’s subjective reasons and are sufficiently transparent for the agent. Third, this conception of self-transparent action is a questionable idealization. (...) As shown by psychological research on self-assessment, motivated reasoning, and terror management theory, humans oftentimes have only a limited understanding of their conduct. Self-deception is rather the rule than the exception. Fourth, taking the limited self-transparency of practical reason seriously leads to a socially contextualized conception of moral responsibility.
