Alex John London’s new book, For the Common Good: Philosophical Foundations of Research Ethics highlights the fact that establishing just social arrangements is not only a matter of incentivizing popular will to act for the common good; it also requires filling in informational gaps about which policies, arrangements, and interventions will advance the basic interests of members in an equitable, effective and efficient manner. Promoting justice requires, in part, acquiring the knowledge for how to do so. In developing this point, (...) London carefully traces these missteps in the main philosophical debates and then resuscitates the importance of questions of justice at the heart of research ethics. In doing so, it provides a transformative corrective for the field. This review critically examines one of the central pillars of London’s egalitarian research imperative approach: the way in which the social value of research is closely linked with minimizing uncertainty among reasonable experts.
