Short Synopsis
Why is America so rich and powerful? The answer lies in our genes, according to psychologist John Gartner.

Full Synopsis
Hypomania, a genetically based mild form of mania, endows many of us with unusual energy, creativity, enthusiasm, and a propensity for taking risks. America has an extraordinarily high number of hypomanics—grandiose types who leap on every wacky idea that occurs to them, utterly convinced it will change the world. Market bubbles and ill-considered messianic crusades can be the downside. But there is an enormous upside in terms of spectacular entrepreneurial zeal, drive for innovation, and material success. Americans may have a lot of crazy ideas, but some of them lead to brilliant inventions.

Bringing his audacious and persuasive thesis to life, Gartner offers case histories of some famous Americans who represent this phenomenon of hypomania. These are the real stories you never learned in school about some of those men who made America: Columbus, who discovered the continent, thought he was the messiah. John Winthrop, who settled and defined it, believed Americans were God's new chosen people. Alexander Hamilton, the indispensable founder who envisioned America's economic future, self-destructed because of pride and impulsive behavior.

While these men are extraordinary examples, Gartner argues that many Americans have inherited the genes that have made them the most successful citizens in the world.
