In favor of clear thinking

Bennis, Medin, and Bartels (2009) have contributed an interesting paper on the comparative benefit of moral rules versus cost-benefit analysis. Many of their specific comments are accurate, useful, and insightful. At the same time, we believe they have misrepresented cost-benefit analysis and have reached a set of conclusions that are misguided and, if adopted wholesale, potentially dangerous. Overall, they offer wise suggestions for making CBA more effective, rather than eliminating CBA as a decision-making tool.
