Quality of life research aims to develop and apply indices for the measurement of human welfare. It is an increasingly important field within the social sciences and its results are an important resource for policy making and evaluation. This paper explores the conceptual background of quality of life research. It focuses on its single most important issue: the controversy between the use of ``objective social indicators'' and the use of people's ``subjective evaluations'' as proxies for welfare. Most quality of life researchers today argue that people's own evaluations have an indispensable role in quality of life measurement. I argue that their position must be defended on philosophical grounds, because their use of evaluations commits them to some particular theories of welfare. I explore the connections between theories of welfare in philosophy and the use of evaluations in quality of life research. I conclude that even though evaluations may have a role in particular applications, they are unlikely to have a role in all applications.

Jennifer Prah Ruger (2011) rightly points out that social cooperation is essential for achieving health justice. But she is unhappy with the approach to cooperation that social scientists and philosophers have taken. Her main objection is that their models are based on narrow self-interest. Her own proposal, which she calls "shared health governance", is based on public moral norms instead. If individuals and institutions internalized and followed such norms, justice in health could be achieved. In this commentary, I show that Ruger fundamentally misdiagnoses the problem of social cooperation and health justice. Because of the faulty diagnosis, her own proposal is at best unworkable, at worst utopian.
