Abstract

We agree with Cushman that rationalizations are the product of biological adaptations, but we disagree about their function. The data available do not show that rationalizations allow us to reason better and make better decisions. The data suggest instead that rationalizations serve reputation management goals, and that they affect our behaviors because we are held accountable by our peers.
