Moneyball

Moneyball is ostensibly about baseball, but it is really about how data-driven thinking defeats conventional wisdom in any competitive domain. Michael Lewis follows Billy Beane, the general manager of the Oakland Athletics, as he uses statistical analysis to build a competitive team on a fraction of the budget of rich teams like the Yankees. Beane's insight was that the market for baseball players was inefficient — scouts valued the wrong attributes because they relied on intuition rather than evidence.

The book changed baseball permanently, but its lessons extend far beyond sports. Any industry where decisions are made by gut feeling rather than data analysis has Moneyball-style inefficiencies waiting to be exploited. Whether you are hiring employees, pricing products, or allocating capital, the question Moneyball teaches you to ask is: what does the evidence actually say, and why is the market ignoring it?
