The Future Of Law And Neuroscience, Owen D. Jones

Vanderbilt Law School Faculty Publications

I was asked to speculate about where the field of Law and Neuroscience may be ten years from now. In that spirit (and while recognizing that the future rarely complies with our predictions) I attempt here some extrapolations. I first consider potential advances in the technologies for monitoring and manipulating brain states, the techniques for analyzing brain data, and the efforts to further integrate relevant fields. I then consider potential neurolaw developments relevant to: (1) detecting things law cares about; (2) individualizing developmental states and brain states; (3) evidence-based legal reforms; (4) legal decision-making; and (5) brain-brain interfaces.

Detecting Mens Rea In The Brain, Owen D. Jones, Read Montague, Gideon Yaffe

Vanderbilt Law School Faculty Publications

What if the widely used Model Penal Code (MPC) assumes a distinction between mental states that doesn’t actually exist? The MPC assumes, for instance, that there is a real distinction in real people between the mental states it defines as “knowing” and “reckless.” But is there?

If there are such psychological differences, there must also be brain differences. Consequently, the moral legitimacy of the Model Penal Code’s taxonomy of culpable mental states – which punishes those in defined mental states differently – depends on whether those mental states actually correspond to different brain states in the way the MPC categorization …

Predicting Variation In Endowment Effect Magnitudes, Owen D. Jones, C. Jaeger, S. Brosnan, D. Levin

Vanderbilt Law School Faculty Publications

Hundreds of studies demonstrate human cognitive biases that are both inconsistent with “rational” decisionmaking and puzzlingly patterned. One such bias, the “endowment effect” (also known as “reluctance to trade”), occurs when people instantly value an item they have just acquired at a much higher price than the maximum they would have paid to acquire it. This bias impedes a vast range of real-world transactions, making it important to understand. Prior studies have documented items that do or do not generate endowment effects, and have noted that the effects vary in magnitude. But none has predicted any of the substantial between-item …

How Should Justice Policy Treat Young Offenders?, Owen D. Jones, B. J. Casey, Richard J. Bonnie, Et Al .

Vanderbilt Law School Faculty Publications

The justice system in the United States has long recognized that juvenile offenders are not the same as adults, and has tried to incorporate those differences into law and policy. But only in recent decades have behavioral scientists and neuroscientists, along with policymakers, looked rigorously at developmental differences, seeking answers to two overarching questions: Are young offenders, purely by virtue of their immaturity, different from older individuals who commit crimes? And, if they are, how should justice policy take this into account?

A growing body of research on adolescent development now confirms that teenagers are indeed inherently different from adults, …

Brain Imaging For Legal Thinkers: A Guide For The Perplexed, Owen D. Jones, Joshua W. Buckholtz, Jeffrey D. Schall, Rene Marois

Vanderbilt Law School Faculty Publications

It has become increasingly common for brain images to be proffered as evidence in criminal and civil litigation. This Article - the collaborative product of scholars in law and neuroscience - provides three things.

First, it provides the first introduction, specifically for legal thinkers, to brain imaging. It describes in accessible ways the new techniques and methods that the legal system increasingly encounters.

Second, it provides a tutorial on how to read and understand a brain-imaging study. It does this by providing an annotated walk-through of the recently-published work (by three of the authors - Buckholtz, Jones, and Marois) that …

Law, Responsibility, And The Brain, Owen D. Jones, Hakwan C. Lau, Dean Mobbs, Christopher D. Frith

Vanderbilt Law School Faculty Publications

This article addresses new developments in neuroscience, and their implications for law. It explores, for example, the relationships between brain injury and violence, as well as the connections between mental disorders and criminal behaviors. It discusses a variety of issues surrounding brain fingerprinting, the use of brain scans for lie detection, and concerns about free will. It considers the possible uses for, and legal implications of, brain-imaging technology. And it also identifies six essential limits on the use of brain imaging in courtroom procedures.

Behavioral Genetics And Crime, In Context, Owen D. Jones

Vanderbilt Law School Faculty Publications

This Article provides an introduction to some of the key issues at the intersection of behavioral genetics and crime.

It provides, among other things, an overview of the emerging points of consensus, scientifically, on what behavioral genetics can and cannot tell us about criminal behavior. It also discusses a variety of important implications (as well as complexities) of attempting to use insights of behavioral genetics in legal contexts.
