Optimising the wrong metrics might make you win the finite game, but lose the infinite one. Beware what you chase.

James P. Carse wrote that there are two kinds of games in life: finite and infinite. A finite game is played to win; there are clear victors and losers. An infinite game is played to keep playing; the goal is to maximize winning across all participants. Debate is a finite game. Marriage is an infinite game. The midterm elections are finite games. American democracy is an infinite game. A great deal of unnecessary suffering in the world comes from not knowing the difference. A bad fight can destroy a marriage. A challenged election can destabilize a democracy. In baseball, winning the World Series is a finite game, while growing the popularity of Major League Baseball is an infinite game. What happened, I think, is that baseball’s finite game was solved so completely in such a way that the infinite game was lost.What moneyball has done to American culture
