Book Preview: #1 The Indians' manager, Lou Boudreau, used statistical analysis to turn Ted Williams's hits into outs. Today, every player is treated like Ted Williams, and teams analyze every variable they can quantify and attach a value to.

#2 The term Moneyball is now used to describe any statistical approach in domains long ruled by the gut. Baseball is a good example of a transparent model, as everyone can access the stats and understand how they're interpreted.

#3 The model I use to manage my family's food is a simplified version of the real world's complexity. It is always making mistakes, because it is, by its very nature, a simplification.

#4 Models are created to simplify a complex world into a simple version that can be easily understood and from which important facts and actions can be inferred. They are opinions embedded in mathematics.
