Predicting The Knowledge: Recklessness Distinction In The Human Brain, Owen D. Jones, Iris Vilares, Michael J. Wesley, Woo-Young Ahn, Et Al.

Vanderbilt Law School Faculty Publications

Criminal convictions require proof that a prohibited act was performed in a statutorily specified mental state. Different legal consequences, including greater punishments, are mandated for those who act in a state of knowledge, compared with a state of recklessness. Existing research, however, suggests people have trouble classifying defendants as knowing, rather than reckless, even when instructed on the relevant legal criteria.

We used a machine-learning technique on brain imaging data to predict, with high accuracy, which mental state our participants were in. This predictive ability depended on both the magnitude of the risks and the amount of information about those …

Parsing The Behavioral And Brain Mechanisms Of Third-Party Punishment, Owen D. Jones, Matthew Ginther, Richard J. Bonnie, Morris B. Hoffman, Francis X. Shen, Kenneth W. Simons, Rene Marois

Vanderbilt Law School Faculty Publications

The evolved capacity for third-party punishment is considered crucial to the emergence and maintenance of elaborate human social organization and is central to the modern provision of fairness and justice within society. Although it is well established that the mental state of the offender and the severity of the harm he caused are the two primary predictors of punishment decisions, the precise cognitive and brain mechanisms by which these distinct components are evaluated and integrated into a punishment decision are poorly understood.

Using a brain-scanning technique known as functional magnetic resonance imaging (fMRI), we implemented a novel experimental design to …

Designed for use in both law schools and beyond, the book provides user-friendly introductions, as well as detailed explorations, of the many current and emerging issues at the intersection of law and neuroscience.

One part of the book lays general foundations by exploring the relationships between law and science generally, and by comparing the views from law and from neuroscience regarding behavior and responsibility. A later part explains the basics of brain structure and function, the methods for …

Neuroscientists In Court, Owen D. Jones, Anthony D. Wagner, David L. Faigman, Marcus E. Raichle

Vanderbilt Law School Faculty Publications

Neuroscientific evidence is increasingly being offered in court cases. Consequently, the legal system needs neuroscientists to act as expert witnesses who can explain the limitations and interpretations of neuroscientific findings so that judges and jurors can make informed and appropriate inferences. The growing role of neuroscientists in court means that neuroscientists should be aware of important differences between the scientific and legal fields, and, especially, how scientific facts can be easily misunderstood by non-scientists,including judges and jurors.

This article describes similarities, as well as key differences, of legal and scientific cultures. And it explains six key principles about neuroscience that …

Evolution And The Expression Of Biases: Situational Value Changes The Endowment Effect In Chimpanzees, Owen D. Jones, Sarah F. Brosnan, Molly Gardner, Susan P. Lambeth, Steven J. Schapiro

Vanderbilt Law School Faculty Publications

Cognitive and behavioral biases, which are widespread among humans, have recently been demonstrated in other primates, suggesting a common origin. Here we examine whether the expression of one shared bias, the endowment effect, varies as a function of context. We tested whether objects lacking inherent value elicited a stronger endowment effect (or preference for keeping the object) in a context in which the objects had immediate instrumental value for obtaining valuable resources (food). Chimpanzee subjects had opportunities to trade tools when food was not present, visible but unobtainable, and obtainable using the tools. We found that the endowment effect for …

Intuitions Of Punishment, Owen D. Jones, Robert Kurzban

Vanderbilt Law School Faculty Publications

Recent work reveals, contrary to wide-spread assumptions, remarkably high levels of agreement about how to rank order, by blameworthiness, wrongs that involve physical harms, takings of property, or deception in exchanges. In The Origins of Shared Intuitions of Justice (http://ssrn.com/abstract=952726) we proposed a new explanation for these unexpectedly high levels of agreement.

Elsewhere in this issue, Professors Braman, Kahan, and Hoffman offer a critique of our views, to which we reply here. Our reply clarifies a number of important issues, such as the interconnected roles that culture, variation, and evolutionary processes play in generating intuitions of punishment.

Law, Biology, And Property: A New Theory Of The Endowment Effect, Owen D. Jones, Sarah F. Brosnan

Vanderbilt Law School Faculty Publications

Recent work at the intersection of law and behavioral biology has suggested numerous contexts in which legal thinking could benefit by integrating knowledge from behavioral biology. In one of those contexts, behavioral biology may help to provide theoretical foundation for, and potentially increased predictive power concerning, various psychological traits relevant to law. This Article describes an experiment that explores that context.

The paradoxical psychological bias known as the endowment effect puzzles economists, skews market behavior, impedes efficient exchange of goods and rights, and thereby poses important problems for law. Although the effect is known to vary widely, there are at …

The Neural Correlates Of Third-Party Punishment, Owen D. Jones, Joshua Buckholtz, Christopher L. Asplund, Paul E. Dux, David H. Zald, John C. Gore, Rene Marois

Vanderbilt Law School Faculty Publications

This article reports the discovery, from the first full-scale law and neuroscience experiment, of the brain activity underlying punishment decisions.

We used functional magnetic resonance imaging (fMRI) to measure brain activity of subjects as they read hypothetical scenarios about harm-causing protagonists and then decided whether to punish and, if so, how much.

The key variables were: a) presence or absence of excusing, justifying, or otherwise mitigating factors (such as acting under duress); and b) harm severity (which ranged from a stolen CD to a rape/murder/torture combination).

Findings include:

(1) Analytic and emotional brain circuitries are jointly involved, yet quite separately …

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.

Endowment Effects In Chimpanzees, Owen D. Jones, Sarah F. Brosnan, Susan P. Lambeth, Mary Catherine Mareno, Amanda S. Richardson, Steven Schapiro

Vanderbilt Law School Faculty Publications

Human behavior is not always consistent with standard rational choice predictions. The much-investigated variety of apparent deviations from rational choice predictions provides a promising arena for the merger of economics and biology. Although little is known about the extent to which other species also exhibit these seemingly irrational patterns of human decision-making and choice behavior, similarities across species would suggest a common evolutionary root to the phenomena.

The present study investigated whether chimpanzees exhibit an endowment effect, a seemingly paradoxical behavior in which humans tend to value a good they have just come to possess more than they would have …

Law And Behavioral Biology, Owen D. Jones, Timothy H. Goldsmith

Vanderbilt Law School Faculty Publications

Society uses law to encourage people to behave differently than they would behave in the absence of law. This fundamental purpose makes law highly dependent on sound understandings of the multiple causes of human behavior. The better those understandings, the better law can achieve social goals with legal tools. In this Article, Professors Jones and Goldsmith argue that many long held understandings about where behavior comes from are rapidly obsolescing as a consequence of developments in the various fields constituting behavioral biology. By helping to refine law's understandings of behavior's causes, they argue, behavioral biology can help to improve law's …

Law, Evolution, And The Brain: Applications And Open Questions, Owen D. Jones

Vanderbilt Law School Faculty Publications

This essay discusses several issues at the intersection of law and brain science. If focuses principally on ways in which an improved understanding of how evolutionary processes affect brain function and human behavior may improve law's ability to regulate behavior. It explores sample uses of such "evolutionary analysis in law" and also raises questions about how that analysis might be improved in the future. Among the discussed uses are: 1) clarifying cost-benefit analyses; 2) providing theoretical foundation and potential predictive power; 3) assessing comparative effectiveness of legal strategies; and 4) revealing deep patterns in legal architecture. Throughout, the essay emphasizes …

Proprioception, Non-Law, And Biolegal History, Owen D. Jones

Vanderbilt Law School Faculty Publications

This Article explores several advantages of incorporating into law various insights from behavioral biology about how and why the brain works as it does. In particular, the Article explores the ways in which those insights can help illuminate the deep structure of human legal systems. That effort is termed "biolegal history."

Through The Lens Of The Sequence, Ellen Wright Clayton

Vanderbilt Law School Faculty Publications

The completion of the rough draft of the human genome is a scientific feat worthy of celebration. But the media attention that has been devoted to the Human Genome Project demonstrates that most people are not as interested in what the sequence is as in what it means for individuals and for society, for good or for ill. My purpose in writing this essay is to discuss how the project was conducted here in the United States, and some of the implications of knowing the sequence (or more aptly, a sequence).

Evolutionary Analysis In Law: Some Objections Considered, Owen D. Jones

Vanderbilt Law School Faculty Publications

This Article appears in a special issue of the Brooklyn Law Review on DNA: Lessons from the Past - Problems for the Future. It first addresses why law needs insights from behavioral biology, and then identifies and responds to a variety of structural and conceptual barriers to such evolutionary analysis in law.

The Evolution Of Irrationality, Owen D. Jones

Vanderbilt Law School Faculty Publications

The place of the rational actor model in the analysis of individual and social behavior relevant to law remains unresolved. In recent years, scholars have sought frameworks to explain: a) disjunctions between seemingly rational behavior and seemingly irrational behavior; b) the origins of and influences on law-relevant preferences, and c) the nonrandom development of norms. This Article explains two components of an evolutionary framework that, building from accessible insights of behavioral biology, can encompass all three. The components are: "time-shifted rationality" and "the law of law's leverage."

On The Nature Of Norms: Biology, Morality, And The Disruption Of Order, Owen D. Jones

Vanderbilt Law School Faculty Publications

This essay discusses the legal implications of bio-behavioral underpinnings to norms, morality, and economic order. It first discusses the recent book "The Great Disruption: Human Nature and the Reconstitution of Social Order," in which Francis Fukuyama explores the importance of evolved human nature to the reconstruction of social order and a thriving economy. It then addresses the extent to which we can usefully view law-relevant norms as products of evolutionary - as well as economic - processes.

Law And The Biology Of Rape: Reflections On Transitions, Owen D. Jones

Vanderbilt Law School Faculty Publications

This Article serves is a sequel to a previous Article: Sex, Culture, and the Biology of Rape: Toward Explanation and Prevention, 87 Cal. L. Rev. 827 (1999). Part I briefly considers the threshold question: why consider the behavioral biology of sexual aggression at all? Part II proposes that the first step in transitioning to a more accurate and more useful model of rape behavior is to avoid a number of common definitional ambiguities that plague most rape discussions. Because those ambiguities are particularly likely to foster misunderstandings about biobehavioral perspectives, Part II also clarifies the scope of what biobehavioral theories …

Law And Biology: Toward An Integrated Model Of Human Behavior, Owen D. Jones

Vanderbilt Law School Faculty Publications

As first year law students unhappily discover, the meaning of "law" is frustratingly protean, shifting by usage and user. Depending on whom you ask, law is a system of rules, a body of precedents, a legislative enactment, a collection of norms, a process by which social goals are pursued, or some dynamic mixture of these. Law's principal purpose is to define and protect individual rights, to ensure public order, to resolve disputes, to redistribute wealth, to dispense justice, to prevent or compensate for injury, to optimize economic efficiency, or perhaps to do something else. And yet one thing is irreducibly …
