Neuroimaging And The "Complexity" Of Capital Punishment, O. Carter Snead

O. Carter Snead

The growing use of brain imaging technology to explore the causes of morally, socially, and legally relevant behavior is the subject of much discussion and controversy in both scholarly and popular circles. From the efforts of cognitive neuroscientists in the courtroom and the public square, the contours of a project to transform capital sentencing both in principle and in practice have emerged. In the short term, these scientists seek to play a role in the process of capital sentencing by serving as mitigation experts for defendants, invoking neuroimaging research on the roots of criminal violence to support their arguments. Over …

Actions Speak Louder Than Images: The Use Of Neuroscientific Evidence In Criminal Cases, Stephen J. Morse

All Faculty Scholarship

This invited commentary for Journal of Law & the Biosciences considers four empirical studies previously published in the journal of the reception of neuroscientific evidence in criminal cases in the United States, Canada, England and Wales, and the Netherlands. There are conceded methodological problems with all, but the data are nonetheless instructive and suggestive. The thesis of the comment is that the courts are committing the same errors that have bedeviled the reception of psychiatric and psychological evidence. There is insufficient caution about the state of the science, and more importantly, there is insufficient understanding of the relevance of the …

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

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 …

In The Wasteland Of Your Mind: Criminology, Scientific Discovieries And The Criminal Process, Michael L. Perlin, Alison Lynch

Articles & Chapters

This paper addresses a remarkably-underconsidered topic: the potential impact of scientific discoveries and an increased understanding of the biology of human behavior on sentencing decisions in the criminal justice system, specifically, the way that sentencing has the capacity to rely on scientific evidence (such as brain imaging) as a mitigating factor (or perhaps, in the mind of some, as an aggravating factor) in determining punishment.

Such a new method of evaluating criminality, we argue, can be beneficial not only for the defendant, but also for the attorneys and judge involved in the case. If used properly, it may help to …

Some studies have reported the ability to detect lies, with a high degree of accuracy, by analyzing brain data acquired using functional magnetic resonance imaging (fMRI). But is this new technology ready for its day in court?

This consensus knowledge brief from the MacArthur Foundation Research Network on Law and Neuroscience takes a closer look at the potential and pitfalls of fMRI lie detection techniques, providing insight into the areas of the brain involved in lying, the impact of memory on deception, how countermeasures may foil our efforts to detect lies, and factors that can create cause for concern about …
