Measuring factors associated with identification thresholds in fingerprint analysts

Abstract

The goal of this research is to measure and identify factors associated with identification thresholds in fingerprint analysts. Conclusions reached in friction ridge comparisons require the application of individual thresholds. While previous studies have investigated the mechanisms behind value determinations, or on the perceived stress reported by forensic examiners, only a few have focused on the influence of personality traits and environmental factors on identification thresholds. This study measures how individual traits and workplace policies may shape these thresholds. Participants were presented with latent prints and tasked with making value determinations before conducting a latent print comparison. Post-trial, participants responded to a series of survey inquiries focusing on their personalities and interactions within the work environment. Our results demonstrate a significant positive correlation between Need for Closure score and the number of Identification decisions, as well as a significant positive correlation between Stress levels and the number of Identification decisions.
