Some Stanford researchers say they have found regular biases in the conduct of baseball umpires. Not surprising, I suppose. But the article did bring to mind an old story about a rookie umpire preparing for his first major league game.
He went in turn to each of the three veteran umpires in the locker room to ask their philosophy about umpiring.
"I call 'em as I see 'em," said the first.
"I call 'em as they are," said the second.
The oldest and wisest umpire had a different point of view. "They ain't nothing 'til I call 'em."
That third viewpoint is a lot like they way members of Congress think about public policy.
