Study: Juries often get it wrong

A new Northwestern University study shows that juries in criminal cases are reaching incorrect verdicts. The study, which looked at 271 cases in four areas of Illinois, found that as many as one in eight juries is making the wrong decision – by convicting an innocent person or acquitting a guilty one.

In each case, while the jury deliberated, the judge filled out a questionnaire detailing what his or her verdict would have been had it been a bench trial. The verdicts only matched in 77 percent of cases. The study assumed that judges are at least as likely as a jury to make a correct verdict, leading to the conclusion that juries are only correct 87 percent of the time or less.

The study was conducted by Bruce Spencer, a Northwestern statistics professor, and will be published in the July issue of the Journal of Empirical Legal Studies. Spencer said in a statement that it would take a much larger study to truly predict the accuracy of jury verdicts nationwide in all cases.
