Abstract The Hawthorne effect refers to the tendency of individuals behave differently when they know are being studied. In forensic science domain, concerns have been raised about “strategic examiner,” where examiner uses different decision thresholds depending on whether in a test situation or working an actual case. blind testing conducted by Houston Forensic Science Center (“HFSC”) firearms examination presents unique opportunity hypothesis that rate inconclusive calls differs for discovered vs. undiscovered tests firearm examination. Over 5 years, 529 item comparisons were filtered into casework at HFSC. items was 56.4%, while 39.3%. Thus, percentage 43.5% higher among than items. This pattern results held bullet (83% 59%) and cartridge case (29% 20%) both same‐source different‐source comparisons. These findings corroborate examiners tested demonstrate necessity if research goal is evaluate performance conducting casework.
