More on Bennettian Possible Worlds

HT writes in, wondering about this BPW,

Bill Bennett says his statement about abortion and crime rates was a thought experiment. That is a sad use of Einstein's phrase. I wonder, what would be the impact on crime of providing all black babies with the financial and social resources available to George W. Bush? Property and violent crime rates might decline, but DWI convictions would skyrocket. The incidence of illegal insider stock trading would increase, but neither the indictment or conviction rate would change. As Molly Ivens and others have said, W was born on third base and thinks he hit a triple.
