Sam Miller of Baseball Prospectus wrote a compelling article on wins above replacement (WAR) for ESPN the Magazine, and there was one particular section that was most interesting to me:

I'm not a mathematician and I'm not a scientist. I'm a guy who tries to understand baseball with common sense. In this era, that means embracing advanced metrics that I don't really understand. That should make me a little uncomfortable, and it does. WAR is a crisscrossed mess of routes leading toward something that, basically, I have to take on faith.

And faith is irrational and anti-intellectual, right? Faith is for rain dances and sun gods, for spirituality but not science. Actually, no. Faith is how we organize a complicated modern world.
