This book "challenges us to go beyond the headlines, which often focus on what politicians do (or say theyll do), and to concentrate instead on what's really important: what shapes our response. Shenkman argues that, contrary to what we tell ourselves, it's our instincts rather than arguments appealing to reason that usually prevail. Pop culture tells us we can trust our instincts, but science is proving that when it comes to politics our Stone-Age brain often malfunctions, misfires, and leads us astray"--Dust jacket flap.
