We change sentencing recommendations often enough (around the world, anyway) that it must be possible to tell whether doubling the sentence for a particular crime actually has any effect on the number of people carrying it out.
Anyone know of any studies?
My personal intuition is that 99% of people who carry out crimes don't think about how big the sentence is at all. But I'm very happy to be proven wrong with actual numbers.
