What surprising lessons can we learn from COVID-19?

From the spread of COVID-19 to the rise of political polarisation, from implicit bias to genetically modified food, from NASA to Netflix - it's time to think differently about how change works.

Professor Damon Centola is the world expert in the new science of networks. His ground-breaking research across areas as disparate as voting, health, technology and finance has highlighted powerful and highly effective new ways to ensure lasting change. In this book, Centola distils more than a decade of deep experience into a fascinating new theory that challenges previous assumptions that new ideas are either contagious or not.

Change shows that beliefs and behaviours are not transmitted from person to person in the simple way that a virus is. The real story of social change is more complex and much more interesting. When we are exposed to a new idea, our social networks guide our responses in striking and surprising ways. Drawing on deep yet accessible research and fascinating examples, Change presents a paradigm-shifting new science for understanding what drives change, recognising our blind spots and how we can change the world around us.
