Time-Shifted Rationality And The Law Of Law's Leverage: Behavioral Economics Meets Behavioral Biology, Owen D. Jones

Owen Jones

A flood of recent scholarship explores legal implications of seemingly irrational behaviors by invoking cognitive psychology and notions of bounded rationality. In this article, I argue that advances in behavioral biology have largely overtaken existing notions of bounded rationality, revealing them to be misleadingly imprecise - and rooted in outdated assumptions that are not only demonstrably wrong, but also wrong in ways that have material implications for subsequent legal conclusions. This can be remedied. Specifically, I argue that behavioral biology offers three things of immediate use. First, behavioral biology can lay a foundation for both revising bounded rationality and fashioning …

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

Owen Jones

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 …

The Evolution Of Irrationality, Owen D. Jones

Owen Jones

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."

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

Owen Jones

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 …

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 …

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

Owen Jones

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 …

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

Owen Jones

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

Owen Jones

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 …

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

Owen Jones

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

Owen Jones

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 …

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

Owen Jones

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 …

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

Owen Jones

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 …

Law & Neuroscience: What, Why, And Where To Begin, Owen D. Jones, Jeffrey D. Schall, Francis X. Shen

Owen Jones

This provides the Summary Table of Contents and Chapter 1 of our coursebook “Law and Neuroscience” (forthcoming April 2014, from Aspen Publishing). 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 …

The Origins Of Shared Intuitions Of Justice, Owen D. Jones, Paul H. Robinson, Robert Kurzban

Owen Jones

Contrary to the common wisdom among criminal law scholars, empirical evidence reveals that people's intuitions of justice are often specific, nuanced, and widely shared. Indeed, with regard to the core harms and evils to which criminal law addresses itself-physical aggression, takings without consent, and deception in transactions-the shared intuitions are stunningly consistent across cultures as well as demographics. It is puzzling that judgments of moral blameworthiness, which seem so complex and subjective, reflect such a remarkable consensus. What could explain this striking result?

The authors theorize that one explanation may be an evolved predisposition toward these shared intuitions of justice, …

Realities Of Rape: Of Science And Politics, Causes And Meanings, Owen D. Jones

Owen Jones

This review essay discusses the book A Natural History of Rape: Biological Bases of Sexual Coercion, by Randy Thornhill and Craig Palmer (MIT Press, 2000). The essay builds on work previously appearing in Owen D. Jones, Sex, Culture, and the Biology of Rape: Toward Explanation and Prevention, 87 Cal. L. Rev. 827 (1999) and Owen D. Jones, Law and the Biology of Rape: Reflections on Transitions, 11 Hastings Women's Law Journal 151 (2000).

Sex, Culture, And The Biology Of Rape: Toward Explanation And Prevention, Owen D. Jones

Owen Jones

For all that has been written about rape, its multiple causes remain insufficiently understood for law to deter it effectively. This follows, in part, from inadequately interdisciplinary study of rape causation. This Article argues that integrating life science and social science perspectives on sexual aggression can improve law's model of rape behavior, and further our efforts to reduce its incidence.

The Article first explains biobehavioral theories of sexual aggression, and offers a guide to common but avoidable errors in assessing them. It then compares a number of those theories' predictions with existing data and demonstrates how knowledge of the effects …

Realism, Punishment, And Reform, Owen D. Jones, Paul H. Robinson, Robert Kurzban

Owen Jones

Professors Donald Braman, Dan Kahan, and David Hoffman, in their article "Some Realism About Punishment Naturalism," to be published in an upcoming issue of the University of Chicago Law Review, critique a series of our articles: Concordance and Conflict in Intuitions of Justice (http://ssrn.com/abstract=932067), The Origins of Shared Intuitions of Justice (http://ssrn.com/abstract=952726), and Intuitions of Justice: Implications for Criminal Law and Justice Policy (http://ssrn.com/abstract=976026). Our reply, here, follows their article in that coming issue.

As we demonstrate, they have misunderstood our views on, and thus the implications of, widespread agreement about punishing the "core" of wrongdoing. Although much of their …

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

Owen Jones

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."

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

Owen Jones

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

Owen Jones

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.

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

Owen Jones

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 …

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

Owen Jones

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 …

Intuitions Of Punishment, Owen D. Jones, Robert Kurzban

Owen Jones

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.

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

Owen Jones

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.

Evolutionary Analysis In Law: An Introduction And Application To Child Abuse, Owen D. Jones

Owen Jones

For contemporary biologists, behavior - like physical form - evolves. Although evolutionary processes do not dictate behavior in any inflexible sense, they nonetheless contribute significantly to the prevalence of various behavioral predispositions that, in turn, tend to yield observable patterns of behavior within every known species.

This Article explores the implications for law of evolved behavioral predispositions in humans, urging both caution and optimism.

Part I of the Article provides A Primer in Law-Relevant Evolutionary Biology, assuming no prior knowledge in the subject. Part II coins the term evolutionary analysis in law and proposes a model for conducting it. That …

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

Owen Jones

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 …

Sex Selection: Regulating Technology Enabling The Predetermination Of A Child's Gender, Owen D. Jones

Owen Jones

The debate over the prohibition of sex (or gender) selection (also known as "preselection" or "predetermination"), has focused almost exclusively on the context of aborting a "wrong-sex" fetus after a fetal gender-identification procedure. Despite the fact that sex selection abortions represent only a small subset of sex selection procedures, attitudes toward the former are driving general policy approaches to the latter. However, the issues are analytically distinct, and only during the former infancy of the pre-conceptive (and non-abortive post-conceptive) technology for sex selection were members on both sides of the debate afforded the economy of using one logic to support …

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 …

Brain Scans As Evidence: Truths, Proofs, Lies, And Lessons, Owen D. Jones, Francis X. Shen

Owen Jones

This contribution to the Brain Sciences in the Courtroom Symposium identifies and discusses issues important to admissibility determinations when courts confront brain-scan evidence. Through the vehicle of the landmark 2010 federal criminal trial U.S. v. Semrau (which considered, for the first time, the admissibility of brain scans for lie detection purposes) this article highlights critical evidentiary issues involving: 1) experimental design; 2) ecological and external validity; 3) subject compliance with researcher instructions; 4) false positives; and 5) drawing inferences about individuals from group data. The article’s lessons are broadly applicable to the new wave of neurolaw cases now being seen …
