Sorting Guilty Minds, Owen D. Jones, Francis X. Shen, Morris B. Hoffman, Joshua D. Greene, Rene Marois

Owen Jones

Because punishable guilt requires that bad thoughts accompany bad acts, the Model Penal Code (MPC) typically requires that jurors infer the past mental state of a criminal defendant. More specifically, jurors must sort that mental state into one of four specific categories - purposeful, knowing, reckless, or negligent - which in turn defines the nature of the crime and the extent of the punishment. The MPC therefore assumes that ordinary people naturally sort mental states into these four categories with a high degree of accuracy, or at least can reliably do so when properly instructed. It also assumes that ordinary …

Decoding Guilty Minds: How Jurors Attribute Knowledge And Guilt, Owen D. Jones, Matthew R. Ginther, Francis X. Shen, Richard J. Bonnie, Morris B. Hoffman, Kenneth W. Simons

Owen Jones

A central tenet of Anglo-American penal law is that in order for an actor to be found criminally liable, a proscribed act must be accompanied by a guilty mind. While it is easy to understand the importance of this principle in theory, in practice it requires jurors and judges to decide what a person was thinking months or years earlier at the time of the alleged offense, either about the results of his conduct or about some elemental fact (such as whether the briefcase he is carrying contains drugs). Despite the central importance of this task in the administration of …

Economics, Behavioral Biology, And Law, Owen D. Jones, Erin O'Hara O'Connor, Jeffrey Evans Stake

Owen Jones

The article first compares economics and behavioral biology, examining the assumptions, core concepts, methodological tenets, and emphases of the two fields. Building on this, the article then compares the applied interdisciplinary fields of law and economics, on one hand, with law and behavioral biology, on the other - highlighting not only the most important similarities, but also the most important differences.

The article subsequently explores ways that biological perspectives on human behavior may prove useful, by improving economic models and the behavioral insights they generate. The article concludes that although there are important differences between the two fields, the overlaps …

Taking Another Look At Second-Look Sentencing, Meghan J. Ryan

Meghan J. Ryan

An unprecedented number of Americans are currently behind bars. Our high rate of incarceration, and the high bills that it generates for American taxpayers, has led to a number of proposals for sentencing reform. For example, a bill recently introduced in Congress would roll back federal mandatory minimum sentences for certain drug offenders, and the Obama Administration has announced a plan to grant clemency to hundreds of non-violent drug offenders. Perhaps the most revolutionary proposal, though, is one advanced by the drafters of the Model Penal Code, namely that judges be given the power to resentence offenders who have been …

We explicate and evaluate arguments both for and against the insanity defense itself, different versions of the insanity defense (M'Naghten, Model Penal Code, and Durham (or Product)), the Irresistible Impulse rule, and various reform proposals.
