This book recognises that we don't understand who we are or why we do what we do. This is because our models of human behaviour, based on a naive view of rationality, are flawed. Recognising the limitations of rationality, we still need to fill the vacuum with better explanations for self-destructive behaviour in individuals and groups, from overeating to addiction to fighting wars in far-off places for unclear reasons and with unclear plans.

By lifting the veil on human irrationality, Andy Hira's analysis can help us to understand and challenge ourselves and society to solve persistent problems, from world hunger to climate change. the fact that we already know how to solve these and a myriad of other social problems, yet never do so, reveals the need for a fresh perspective.
