Any serious attempt to explain corruption has to be holistic. People are corrupt for numerous reasons, and even where there is an identifiable primary motivation—such as greed or opportunity—this differs from one person or group to the next. We need to identify the various factors that explain corruption; otherwise, attempts to control it will be futile. ‘Psycho-social and cultural explanations’ focuses on individuals, their relationship to society, and how cultures might relate to corruption using an approach based on Anthony Giddens’ structuration theory. In the real world, factors interact, overlap, and combine with each other in complex ways.
