Peter Davis is Director of the COMPASS Research Centre and Professor of Sociology at the University of Auckland, with cross-appointments in the School of Population Health and in the Department of Statistics, also at the University of Auckland. Previously he served as Professor of Public Health at the University of Otago′s Christchurch School of Medicine. Davis specialises in medical sociology, and has achieved international recognition in his field, having worked as a consultant for the World Health Organisation. His main interests are in research methods, social structures, and policy, particularly health policy and health services. He has collaborated with colleagues in health research and in social statistics on a number of major surveys since the 1970s. He was Senior Editor (Health Policy) at the international journal, Social Science and Medicine, until 2012.

While causal thinking is at the heart of social science research and explanation, too little rigorous attention is paid by researchers as how to strengthen claims of causality.  This comprehensive collection draws together some of the best papers that point to the challenges of establishing causality and provide ways of addressing many of these challenges. It provides the resources to help both researchers and students address the question of causality much more systematically and convincingly than is often the case.
