To solve the global challenges we face, we need our best brain power. So how do we create genius environments, help our brains flourish and boost group thinking to achieve that? Neuroscientist and author of The Science of Fate Hannah Critchlow shares why two heads are better than one, electrifying our minds with brain synchronicity, exploring the power of intuition and increasing our tolerance for uncertainty. Her new book is Joined-Up Thinking: The Science of Collective Intelligence and its Power to Change our Lives.
