Soxblog has some thoughts on the applicability (or not) of the Bill James/Moneyball approach outside of the baseball world (which rather completes the circle, since Michael Lewis’ book worked in large part because he brought lessons from Wall Street to bear on baseball). I agree with his diagnosis that baseball is much more easily subject to objective analysis because the number of variables that have changed over time is pretty minor compared to other fields. Mike and the Mad Dog also interviewed Lewis today (audio link here; hat tip to Dr. Manhattan, who emailed the link with the comment that it shows “an example of parties speaking different languages even though the conversation is in English”).
