Paul DePodesta Quotes in Moneyball
There was, for starters, the tendency of everyone who actually played the game to generalize wildly from his own experience. People always thought their own experience was typical when it wasn't. There was also a tendency to be overly influenced by a guy's most recent performance: what he did last was not necessarily what he would do next. Thirdly—but not lastly—there was the bias toward what people saw with their own eyes, or thought they had seen. The human mind played tricks on itself when it relied exclusively on what it saw, and every trick it played was a financial opportunity for someone who saw through the illusion to the reality.

"He's the only player in the history of the SEC with three hundred hits and two hundred walks," says Paul, looking up from his computer.
It's what he doesn't say that is interesting … He doesn't explain why walks are important. He doesn't explain that he has gone back and studied which amateur hitters made it to the big leagues, and which did not, and why.

"I made one decision based on money in my life—when I signed with the Mets rather than go to Stanford—and I promised I'd never do it again." After that, Billy confined himself to the usual blather about personal reasons. None of what he said was terribly rational or "objective"—but then, neither was he. Within a week, he was back to scheming how to get the Oakland A’s back to the playoffs, and Paul DePodesta was back to being on his side.
