Most research that has attempted to predict verdict preferences on the basis of stable juror characteristics, such as attitudes and personality traits, has found that individual differences among jurors are not very useful predictors, accounting for only a small proportion of the variance in verdict choices. Some commentators have therefore concluded that verdicts are overwhelmingly accounted for by "the weight of the evidence," and that differences among jurors have negligible effects. But there is a paradox here: In most cases the weight of the evidence is insufficient to produce firstballot unanimity in the jury (Hans & Vidmar, 1986; Hastie, Penrod, & Pennington, 1983; Kalven & Zeisel, 1966). Different jurors draw different conclusions about the right verdict on the basis of exactly the same evidence. That these differences are consequential is indicated by the frequently replicated fmding that frrst ballot splits are the best-known predictor of the fmal jury verdict. In most laboratory studies of jury decisions, there are some juries, as well as jurors, that reach nonmodal verdicts. The inescapable conclusion is that individual differences among jurors make a difference.
