The parole hearing: Decision or justification?

A detailed content analysis of tape-recordings of 100 randomly selected California parole hearings revealed that these hearings take the form of short, unstructured diagnostic interviews in which the hearing officers ask questions of the prisoners who respond in a very minimal way. Different patterns of questioning and prisoner response occurred for hearings where the eventual decision was to grant parole as opposed to deny parole, and this decision outcome could be predicted with a high degree of accuracy by discriminant function analyses. In general, the hearing officers made their own psychological assessments of the prisoners, even though they lacked knowledge and training in this diagnostic skill. According to the results of this study, the parole decision-making process appears to be a reliable one, but nevertheless its validity is questionable.
