Rationalization of emotion is also rational.

Cushman seeks to explain rationalization in terms of fundamental mental processes, and he hypotheses a selected-for function: information exchange between "rational" and "non-rational" processes in the brain. While this is plausible, his account overlooks the importance - and information value - of rationalizing the emotions of ourselves and others. Incorporating such rationalization would help explain the effectiveness of rationalization and its connection with valuation, as well as raise a challenge to his way of bifurcating "rational" and "non-rational" processes.
