When faced with new challenges, it's easy to feel our solutions need to be equally unprecedented. We think we need a revolution. But what if this is a big mistake? In Evolutionary Ideas, Sam Tatam shows how behavioural science and evolutionary psychology can help us solve tomorrow's challenges, not by divining something the world has never seen, but by borrowing from yesterday's solutions – often in the most unexpected ways. Just as millions of years of evolution have helped craft the wing and dorsal fin, thousands of engineers, designers, marketers and advertisers have toiled to solve many of the problems you face today. Over time, through intent, design, social learning and sheer luck, we have found what works. Armed with an enhanced ability to see these patterns in human innovation, we can now systematically approach the creative process to develop more effective ideas more readily and rapidly. In the same way Japanese engineers reduced bullet train noise by studying the evolved biology of the owl and kingfisher, today we can see how Disney improved the queueing experience in the same way Houston airport made arrivals feel faster (while making people walk further). We'll learn how the chocolate at the bottom of a Cornetto ice cream can improve an Error 404 message, and what a bowl of M&Ms has in common with a canary in a coal mine. These are Evolutionary Ideas. Exploring five of the most critical challenges we face today, we learn how to 'breed' more effective solutions from those that have survived. The result is a dynamic and exciting way of solving problems and supercharging creativity – for anyone in any endeavour.
