The influence of attorney anger on juror decision making.

ABSTRACT

We investigated the interactive effect of attorney anger expression and attorney gender on juror decision-making. Jury eligible Amazon MTurk participants (N = 455) were recruited. They listened to an audio recording of a male or female prosecutor delivering a closing statement with varying levels of authenticity (authentic, inauthentic or no anger). Then, they rendered a verdict. After the verdict, participants filled out various measures: guilty verdict confidence, current feelings of anger, and perceptions of prosecutor trust and competence. We found that the prosecutor's authentic displays of anger provoked anger in the participants, which, subsequently, increased the odds of a guilty verdict and guilty verdict confidence. Moreover, authentic displays of anger improved perceptions of the prosecutor's competence, which also increased the odds of a guilty verdict. However, perceptions of the prosecutor's trustworthiness did not vary, and attorney gender did not play a moderating role. The implications of these findings are discussed.
