In On the Edge: The Art of Risking Everything, Silver compellingly theorizes that humans are in general too risk averse, and that those who can discerningly fight that impulse often benefit greatly in life.
In addition to his day job — which made him a recognizable name — as a forecaster, statistician and writer, Silver is an accomplished poker player. He fittingly, then, begins his analysis of those with high tolerances for risk through a detailed look at the game and those who play it.
It turns out, Silver argues, poker players, astronauts and hedge fund managers have more in common than people may assume, even on a physiological level. “The biggest risk is not taking any risk,” Mark Zuckerberg famously said — a widely-held sentiment in Silicon Valley which Silver explores at length in this book.
