This study involves scale development using theoretically derived items from previous measures and a lay consensual approach for generating new items. Confirmatory factor analysis was used to validate the emergent constructs assessing individual differences in attitudes of prospective jurors. Using case summaries, the Pretrial Juror Attitude Questionnaire (PJAQ) demonstrates superior predictive validity over commonly employed measures of pretrial bias. The PJAQ confirms the importance of theoretically derived constructs assessed by other scales and introduces new constructs to the jury decision‐making literature. The attitudes assessed by the PJAQ are conviction proneness, system confidence, cynicism toward the defense, racial bias, social justice, and innate criminality. Implications for assessing such attitudes and for better understanding the decision‐making process of jurors are discussed.
