An Artificial Intelligence System Suggests Arbitrariness of Death Penalty

The arguments against the death penalty in the United States have centered on due process and fairness. Since the death penalty is so rarely rendered and subsequently applied, it appears on the surface to be arbitrary. Considering the potential utility of determining whether or not a death row inmate is actually executed along with the promising behavior of Artifi cial Neural Networks (ANNs) as classifi ers led us into the development, training, and testing of an ANN as a tool for predicting death penalty outcomes. For our ANN we reconstructed the profi les of 1,366 death row inmates by utilizing variables that are independent of the substantive characteristics of the crime for which they have been convicted. The ANN’s successful performance in predicting executions has serious implications concerning the fairness of the justice system.
