But in fact, your identity is constantly changing - often outside your conscious awareness and sometimes even against your wishes - to reflect the interests of the groups of which you're a part. And that fluid identity has a powerful influence over your feelings, beliefs, and behaviours.In THE POWER OF US, psychologists Packer and Van Bavel integrate their own cutting-edge research in psychology, neuroscience and economics to explain what identity really is and show how to harness its dynamic nature to:Increase our productivity - Improve physical and psychological health - Overcome our individual prejudice - Unlock our altruism - Break the political gridlock - Galvanize others to solve controversial global problemsAlong the way, they explain such seemingly unrelated phenomenon as why men cry at football games but not funerals, why the history of slavery in U.S. counties is one of the best predictors of current day racism, and why Canada keeps a national reserve of maple syrup.
