Internal And External Challenges To Culpability, Stephen J. Morse Jan 2022

Internal And External Challenges To Culpability, Stephen J. Morse

All Faculty Scholarship

This article was presented at “Guilty Minds: A Virtual Conference on Mens Rea and Criminal Justice Reform” at Arizona State University’s Sandra Day O’Connor College of Law. It is forthcoming in Arizona State Law Journal Volume 53, Issue 2.

The thesis of this article is simple: As long as we maintain the current folk psychological conception of ourselves as intentional and potentially rational creatures, as people and not simply as machines, mental states will inevitably remain central to ascriptions of culpability and responsibility more generally. It is also desirable. Nonetheless, we are in a condition of unprecedented internal challenges to …

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, …


The Poverty Of The Neuroscience Of Poverty: Policy Payoff Or False Promise?, Amy L. Wax Jan 2017

The Poverty Of The Neuroscience Of Poverty: Policy Payoff Or False Promise?, Amy L. Wax

All Faculty Scholarship

A recent body of work in neuroscience examines the brains of people suffering from social and economic disadvantage. This article assesses claims that this research can help generate more effective strategies for addressing these social conditions and their effects. It concludes that the so-called neuroscience of deprivation has no unique practical payoff, and that scientists, journalists, and policy-makers should stop claiming otherwise. Because this research does not, and generally cannot, distinguish between innate versus environmental causes of brain characteristics, it cannot predict whether neurological and behavioral deficits can be addressed by reducing social deprivation. Also, knowledge of brain mechanisms yields …


Law, Responsibility, And The Sciences Of The Brain/Mind, Stephen J. Morse Apr 2016

Law, Responsibility, And The Sciences Of The Brain/Mind, Stephen J. Morse

All Faculty Scholarship

This chapter is a submission to the Oxford Handbook of Law and the Regulation of Technology edited by Roger Brownsword. It considers whether the new sciences of the brain/mind, especially neuroscience and behavioral genetics, are likely to transform the law’s traditional concepts of the person, agency and responsibility. The chapter begins with a brief speculation about why so many people think these sciences will transform the law. After reviewing the law’s concepts, misguided challenges to them, and the achievements of the new sciences, the chapter confronts the claim that these sciences prove that we are really not agents and that …


Predicting The Knowledge–Recklessness Distinction In The Human Brain, Iris Vilares, Michael J. Wesley, Woo-Young Woo-Young Ahn, Richard J. Bonnie, Morris B. Hoffman, Owen D. Jones, Stephen J. Morse, Gideon Yaffe, Terry Lohrenz, Read Montague Jan 2016

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 …
