Which of the following is NOT listed as a bias-reduction measure?

• A. Independent Reviews & Peer Review
• B. Quality Assurance/Quality Control
• C. Polygraph Testing
• D. Case Managers

Answer: (C)

Bias reduction in forensic practice comes from practices that keep judgments and results from being swayed by personal opinions or systemic shortcuts. Independent reviews and peer review provide an outside check on methods and conclusions, so errors or biased interpretations aren’t taken at face value. Quality assurance and quality control push for consistent, validated procedures, calibration, and ongoing proficiency testing, which minimizes sloppiness and subjective differences across cases. Case managers help oversee workflows, distribute tasks fairly, and ensure standards are followed, reducing biases that can creep in from rushed decisions or uneven resource allocation.

Polygraph testing, on the other hand, is a tool aimed at deception detection rather than reducing bias in how data is collected, analyzed, or interpreted. Its reliability is debated, and it does not address the processes that bias judgment. That’s why it isn’t listed as a bias-reduction measure.
