'In Morality and the Regulation of Social Behaviour, Naomi Ellemers argues that morality cannot be understood except as a group phenomenon. Using vivid real-world examples backed up by the latest psychological research, Ellemers shows the paramount importance of morality as people govern their own behaviour, look for norms, and seek to fit in. Unlike most research in moral psychology, which has emphasized the contents of moral rules, here we see how group concerns transform vague rules into concrete actions, and motivate us to look for signs of good character and ethical climate. This book provides a vital psychological perspective on morality, groups, and organizational ethics.' - Professor Roger Giner-Sorolla, School of Psychology, University of Kent, UK
