title: Jurors report that risk measure scores matter in sexually violent predator trials, but that other factors matter more.
abstract: After deliberating to a verdict, jurors (N = 462) from 40 sexually violent predator (SVP) trials completed a questionnaire asking them to rate the extent to which risk measure scores, diagnoses, expert witness testimony, and offender characteristics described during the trials influenced their commitment decisions. Jurors reported that offenders' sexual offending history, failure to change, and lack of remorse had the strongest influence on their commitment decisions. They reported that testimony about risk instrument scores (e.g., Static-99) and psychopathy had less influence on their decisions, but those who did report being influenced by instrument results were especially likely to view the offender as being at a high risk for reoffending. Overall, findings suggest that SVP jurors view risk measure results as important, but not as important as other offender, offense, and testimony characteristics, including some that have limited relevance to recidivism risk. Thus, findings also suggest that experts may need to better educate jurors regarding factors that do and do not relate to recidivism risk.
