Where do the best ideas come from? And how do we apply these ideas to the problems we face – at work, in the education of our children, and in the biggest shared challenges of our age: rising obesity, terrorism and climate change? In this bold and inspiring new book, Matthew Syed – the bestselling author of Bounce and Black Box Thinking – argues that individual intelligence is no longer enough; that the only way to tackle these complex problems is to harness the power of our ‘cognitive diversity’. Rebel Ideas is a fascinating journey through the science of team performance. It draws on psychology, economics, anthropology and genetics, and takes lessons from a dazzling range of case-studies, including the catastrophic intelligence failings of the CIA before 9/11, a communication breakdown at the top of Mount Everest, and a moving tale of deradicalization in America’s deep South. It is a book that will strengthen any company, institution or team, but it also offers many individual applications too: the remarkable benefits of personalised nutrition, advice on how to break free of the echo chambers that surround us, and tips on how we can all develop an ‘outsider mindset’. Rebel Ideas offers a radical blueprint for creative problem-solving. It challenges hierarchies, encourages constructive dissent and forces us to think again about where the best ideas come from.
