Decision making by parole interviewers: The effect of case and interview factors

Nonverbal behavior of 103 inmates was coded during their parole interviews, and additional information was obtained from their case files. These data were related to interviewers' pre-and postinterview judgments of the inmates' likelihood of completing parole successfully and to interviewers' ratings of the inmates' honesty during the interview. Results showed that information obtained during the interview significantly affected the interviewers' postinterview judgments. Perceived honesty during the interview was affected significantly by the severity of the inmates' crime and by how much information the inmates' volunteered, how polite they were to the interviewers, and how much the inmates fidgeted during the interviews. Results suggest that the interviews did not improve, and may have lowered, interviewers' accuracy at predicting inmates' success on parole.
