Description
A substantial amount of research has been dedicated to understanding how and why innocent people confess to crimes that they did not commit. Unfortunately, false confessions occur even with the best possible interrogation practices. This study aimed to examine how different types of false confession (voluntary, compliance, and internalization) and the use of jury instructions specific to confessions influences jurors’ verdicts. A sample of 414 participants read a criminal trial case summary that presented one of four reasons why the defendant falsely confessed followed by either the standard jury instruction for confessions or a clarified version. Afterwards, participants completed several items assessing the perceived guilt of the defendant, their attitudes on confessions in general, and their opinions on jury instructions. Although the three confession reasons did not differ among one another, jurors who were given no explanation for the false confession tended to more harshly judge the defendant. Further, the clarified jury instructions did not influence the participants’ judgments. Future research should focus on how expert witness testimonies affect verdicts regarding each type of false confession reason and whether the media may influence a juror’s knowledge of factors that could provoke false confessions.

Description
In recent years, the use of biologically based (neurological, neuropsychological, genetic) evidence in criminal trials as support for claims of mental impairments among offenders has increased in popularity. However, research on how exposure to those arguments affects jury decision-making remains unclear. Specifically, arguments rooted in biology sometimes mitigate and sometimes aggravate judgments of criminal responsibility for mentally ill offenders, and this discrepancy seems to stem from the specific conditions by which that disorder was acquired. The following study’s aim was to uncover the precise mechanism(s) behind this elusive effect. Utilizing a 2x2 between subjects experimental design, participants were presented with a hypothetical crime summary involving an offender with either an onset controllable or uncontrollable mental disorder. Ratings of criminal responsibility and other variables hypothesized to function as mediators were obtained after presentation of a prime supporting either a biologically deterministic or free will argument for human behavior in general. Results indicated that when the defendant’s disorder was the result of the his own actions (onset controllable), a biological prime decreased judgments of criminal responsibility; however, when the disorder was caused by factors out of his control (onset uncontrollable), the prime increased judgments of criminal responsibility. An examination of several possible mechanisms finds the effect mediated by the perception of control the defendant could have had over his own actions at the time of the crime. These results suggest that perceptions of behavioral control are an important contributor to jurors’ formation of criminal responsibility judgments when an offender possesses a mental illness; and arguments advocating a biological basis for human behavior reliably affect blame attribution, suggesting that a societal shift in the perception of free will as a result of increased exposure to biology in general may alter the framework of criminal responsibility judgments.
