This book examines public oath taking as an anti-corruption strategy that has been implemented with successful results in Nigeria and that has applications for other countries struggling with similar problems. The author of the book is the founder of Association of Nigerians against Corruption (ANAC), the NGO that first piloted the oath taking program—in which people swear publically not to either take or receive bribes. Drawing on the experiences of the program and interviews with a number of ANAC participants, the author sheds light on some of the dynamics that underlie corruption, the potential of oath taking, and the importance of grassroots efforts and individual moral agency as forces of change.
