Yes! is full of practical tips based on recent academic research that shows how the psychology of persuasion can provide valuable insights for anyone interested in improving their ability to persuade others - whether in the workplace, at home or even on the internet. It combines the counter-intuition of Freakonomics with the popularising of Does Anything Eats Wasps? For each mini-chapter contains a mystery which is solved in a way that provides food for thought for anyone looking to be more persuasive, and for anyone interested in how the world works.
