The Life You Save May Not Be Your Own

This paper points out an ambiguity in Cass Sunstein’s recent work concerning whose lives and interests are to be promoted by libertarian paternalism, and argues that this ambiguity stems from a lack of clarity regarding how we should understand the relevance of the heuristics and biases literature for democratic theory. The paper attempts to extract from Sunstein’s work an account of how we should go about identifying biases in social choices. It argues that Sunstein’s view on this issue has changed over the years, and identifies a trend in his thinking moving away from libertarian paternalism and toward libertarian welfarism.
