"A new, counterintuitive theory for how social networks influence the spread of behavior. New social movements, technologies, and public-health initiatives often struggle to take off, yet many diseases disperse rapidly without issue. Can the lessons learned from the viral diffusion of diseases be used to improve the spread of beneficial behaviors and innovations? In How Behavior Spreads, Damon Centola presents over a decade of original research examining how changes in societal behavior--in voting, health, technology, and finance--occur and the ways social networks can be used to influence how they propagate. Centola's startling findings show that the same conditions accelerating the viral expansion of an epidemic unexpectedly inhibit the spread of behaviors. While it is commonly believed that "weak ties"--long-distance connections linking acquaintances--lead to the quicker spread of behaviors, in fact the exact opposite holds true. Centola demonstrates how the most well-known, intuitive ideas about social networks have caused past diffusion efforts to fail, and how such efforts might succeed in the future. Pioneering the use of Web-based methods to understand how changes in people's social networks alter their behaviors, Centola illustrates the ways in which these insights can be applied to solve countless problems of organizational change, cultural evolution, and social innovation. His findings offer important lessons for public health workers, entrepreneurs, and activists looking to harness networks for social change.Practical and informative, How Behavior Spreads is a must-read for anyone interested in how the theory of social networks can transform our world"--Provided by publisher.

"Why do people come to reject climate science or the safety and efficacy of vaccines, in defiance of the scientific consensus? A popular view explains bad beliefs like these as resulting from a range of biases that together ensure that human beings fall short of being genuinely rational animals. This book presents an alternative account. It argues that bad beliefs arise from genuinely rational processes. We've missed the rationality of bad beliefs because we've failed to recognize the ubiquity of the higher-order evidence that shapes beliefs, and the rationality of being guided by this evidence. The book argues that attention to higher-order evidence should lead us to rethink both how minds are best changed and the ethics of changing them: we should come to see that nudging - at least usually - changes belief (and behavior) by presenting rational agents with genuine evidence, and is therefore fully respectful of intellectual agency. We needn't rethink Enlightenment ideals of intellectual autonomy and rationality, but we should reshape them to take account of our deeply social epistemic agency"-- Provided by publisher.

Psychologists like to claim that Psychology is a science, yet, until now, the discipline has lacked any real scientific laws, has had no overarching scientific paradigm and has been blighted by poor replicability of research, all of which have dogged the discipline. Attempts to place Psychology under a single scientific umbrella, e.g. Behaviourism, Cognitivism, Biological Science, Social Science or Human Science, have all failed for a host of reasons. This unique book presents a single paradigm for all of Psychology within a framework of Natural Science. For example, it employs as a model an organising principle known in another scientific discipline for over a century, the principle of Homeostasis. Findings across the entire discipline including perception, learning, emotion, stress, addiction, well-being and consciousness are all shown to be consistent with a new paradigm based on this, and other principles drawn from natural science.
