Big Mind describes the emerging field of collective intelligence that’s been 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—can help solve the great challenges of our time. It also forces us to rethink how many existing institutions are organised, from businesses to universities, governments to cities.

On Thursday 7 December, Geoff Mulgan, Cheif Executive of Nesta and author of Big Mind, spoke about some of the book's key themes, during an evening reception at Nesta.
