Corruptible draws on over 500 interviews with some of the world’s top leaders—from the noblest to the dirtiest—including presidents and philanthropists as well as rebels, cultists, and dictators. Some of the fascinating insights include: how facial appearance determines who we pick as leaders, why narcissists make more money, why some people don’t want power at all and others are drawn to it out of a psychopathic impulse, and why being the “beta” (second in command) may actually be the optimal place for health and well-being.

Corruptible also features a wealth of counterintuitive examples from history and social science: you’ll meet the worst bioterrorist in American history, hit the slopes with a ski instructor who once ruled Iraq, and learn why the inability of chimpanzees to play baseball is central to the development of human hierarchies.
