Abstract

Two factors thought to influence jurors' penalty decisions in capital trials—the nature of the crime committed and the defense's portrayal of the convicted offender's character—were examined. Mock jurors were death-qualified and exposed to one of twelve simulated penalty trials. Each “trial” was comprised of one of three capital crimes and one of four defense strategies. Jurors were least punitive in “robbery-murder” conditions and most punitive in “multiple murder” conditions. A conceptual argument against capital punishment was the most effective defense; a “mental illness” defense was the least effective. Penalty decisions were mediated by three attributional variables: (a) juror perceptions of the defendant's volition, (b) juror perceptions of the defendant's future dangerousness, and (c) juror perceptions of the relative competency of the opposing attorneys.
