The book examines the degree to which evaluators seek power for their own interests. This perspective is based on a simple assumption: If you are in possession of an asset that can give you power, why not use it for your own interests? Can we really trust evaluation to be a force for the good? To what degree can we talk about self-interest in evaluation, and is this self-interest something that contradicts other interests such as "the benefit of society?" Such questions and others are addressed in this brilliant, innovative, international collection of pioneering contributions.
