A new field of collective intelligence has emerged in the last few years, prompted by a wave of digital technologies that make it possible for organisations and societies to think at large scale.

This “bigger mind”—human and machine capabilities working together—has the potential to solve the great challenges of our time. So why do smart technologies not automatically lead to smart results? Gathering insights from diverse fields, including philosophy, computer science, and biology, 'Big Mind' reveals how collective intelligence can guide corporations, governments, universities, and societies to make the most of human brains and digital technologies.

Nesta Chief Executive Geoff Mulgan explores how collective intelligence has to be consciously organised and orchestrated in order to harness its powers. He looks at recent experiments mobilising millions of people to solve problems, and at groundbreaking technology like Google Maps and Dove satellites. He also considers why organisations full of smart people and machines can make foolish mistakes—from investment banks losing billions to intelligence agencies misjudging geopolitical events—and shows how to avoid them.

"In addition to getting the science right, Mulgan is also a gifted writer who draws upon literature and philosophy to illustrate his points [and] understands that collective intelligence should be designed to serve collective welfare, ultimately at the planetary scale. This is public policy for the future." David Sloan Wilson, Distinguished Professor of Biological Sciences and Anthropology, Binghamton University

"Geoff Mulgan is one of the most persistently creative policy thinkers of the past 25 years, and his latest offering 'Big Mind' is no exception. It charts the emergence of the new field of collective intelligence, which is harnessing human and digital capabilities for collaborative problem-solving on an unprecedented scale. It’s an argument with profound implications for the way we organise science, universities, businesses and governments".  James Wilsdon, Guardian, Favourite Reads 2017
