This volume brings together a diverse group of authors who have been associated with Robyn Dawes over the years. The breadth of topics covered reflects Dawes’s wide-ranging impact on psychological theory and empirical practice. The two themes of rationality and social responsibility are well developed in the book. Each chapter is a stimulus for new research and a reminder not to forget the hard-won lessons of the past – in particular, those taught by Robyn Dawes.
