In order to investigate the role of pre-trial attitudes about forensic science in juror decision-making, a previous study demonstrated the predictive validity of the Forensic Evidence Evaluation Bias Scale (FEEBS), using a murder trial scenario, which featured ambiguous prosecution DNA evidence. The current study validates the FEEBS using two new crime types and the conditions include a manipulation of the presence of DNA evidence in the trial scenario. The FEEBS successfully predicted mock jurors' perceptions of the probative value of DNA evidence for both robbery and sexual assault trials. The two subscales of the FEEBS were demonstrated to have different predictive ability depending on the presence or absence of DNA evidence. A confirmatory factor analytic technique was used to validate the underlying two-factor structure of the FEEBS, as previously proposed. These results are discussed with reference to the CSI Effect literature, and the potential for improvement to less empirically supported voir dire questioning techniques.
