The effect of restricted and unrestricted verdict options on juror choice

Data on the effect of limiting the number of verdict options open to jurors on the probability of acquittal are reanalyzed. Strong support is found for a model which postulates that jurors' preferences are single peaked with respect to an underlying verdict severity continuum. Limited support is found for an anchoring effect in which the addition of new verdict options affects the perceived relative fairness of other verdict options. The implication of the single-peakedness model is that some jurors will refuse to vote for conviction if the verdict (punishment) is seen as too harsh even though the defendant is perceived to be guilty of committing a crime.
