In “Prisoner’s Dilemma,” a discursive, funny and sort of nutty Grantland article, stats guru Bill James explains why crowd decorum at baseball games has improved while inmate behavior in penitentiaries has deteriorated. An excerpt:

“In his 1929 book 20,000 Years in Sing Sing, Warden Lewis E. Lawes says that his young daughter, who was born inside the prison, knew all of the prisoners and was allowed to wander freely around the prison, with a few obvious out-of-bounds penalties. Think about what a different world that is from a modern prison. If I could divert your attention for just a second with a serious question: How did we slip backward like that? How did prisons become these violent hellholes that they now are, so that it is unimaginable to have an 8-year-old girl wandering the hallways of a maximum-security lockup?”
