Sir Geoff Mulgan is Professor of Collective Intelligence, Public Policy and Social Innovation at University College London. Formerly he was chief executive of Nesta, and held government roles (1997–2004), including as the Prime Minister’s Strategy Unit director and as Downing Street’s head of policy. He is the founder or co-founder of many organisations, from Demos to Action for Happiness, and the author of Another World is Possible, Social Innovation: how societies find the power to change, Big Mind: how collective intelligence can change our world, and other books.  "The great thing about a complex society is there is space for lots of different kinds of people. There's space for wildly visionary poets and accountants and actuaries and engineers. And they all have a slightly different outlook, but it's the combination of this huge diversity, which makes our societies work. But what we probably do need a bit more of are the bilingual people, the trilingual people who are as at ease spending a day, a week, a year designing how a criminal justice system could look in 50 years and then getting back to perhaps working in a real court or real lawyer's office.”geoffmulgan.comhurstpublishers.com/book/another-world-is-possiblewww.creativeprocess.infowww.oneplanetpodcast.org
