New study shows how often juries get it wrong

EVANSTON, Ill. --- Juries across the country make decisions every day on the fate of defendants, ideally leading to prison sentences that fit the crime for the guilty and release for the innocent. Yet a new Northwestern University study shows that juries in criminal cases many times are getting it wrong.

In a set of 271 cases from four areas, juries gave wrong verdicts in at least one out of eight cases, according to “Estimating the Accuracy of Jury Verdicts,” a paper by a Northwestern University statistician that is being published in the July issue of Journal of Empirical Legal Studies.
