A Glimpse into the Future? The Current, Potential, and Appropriate Role of Functional Magnetic Resonance Imaging (fMRI) Evidence as a Predictor of Dangerousness in the American Criminal Sentencing Context.

摘要

Research suggests there are neurological predictors of violence, such as brain function abnormalities most frequently displayed by violent offenders who may suffer from a psychological phenomenon termed "psychopathy." Functional magnetic resonance imaging (fMRI) can detect signs of some of these brain abnormalities. Neurological markers of violence, evident in a convicted individual's fMRI results, could speak to that offender's tendency to act violently in the future. Can fMRI play a meaningful role in estimating recidivism rates and in sentencing? Even if fMRI evidence meets legal thresholds for use in sentencing, should it be employed in light of many concerns, such as reliability, as the implications of predicting an individual's dangerousness based on fMRI evidence are substantial, especially in the context of defendant rights. Moreover, neurological indicators of violence may undermine a holistic approach to sentencing that considers the convicted individual's particular story.
