Power differences have been and continue to be part of virtually every human interaction. Its range of effects spans from extreme abuse to selfless benevolence. Despite its ubiquity and impact, power has been largely ignored as a factor in social psychological research. Very little is known about power’s direct effects on the judgments and behaviour of individuals and groups. In this volume, the works of prominent researchers have been compiled with a focus on power as a cause of social ills and on remedies to prevent corruption and abuse. The book describes a variety of research perspectives, and hopes to realize the extent of the effects of social power and unearths fundamental elements that hold true across seemingly disparate areas of research.
