A risk-based approach to cognitive bias in forensic science

Area of Science:

• Forensic Science
• Cognitive Psychology
• Risk Management

Background:

• Cognitive bias significantly impacts subjective decision-making in forensic science.
• Forensic organizations are advised to implement strategies to mitigate bias.
• Previous assessments lacked a systematic evaluation of cognitive bias risks.

Purpose of the Study:

• To systematically assess the potential impact of cognitive bias on forensic interpretations.
• To evaluate the effectiveness of existing bias mitigating strategies.
• To identify the latent level of risk posed by cognitive bias across disciplines.

Main Methods:

• Utilized a risk management framework to assess cognitive bias.
• Applied the framework across multiple forensic disciplines.
• Evaluated existing bias mitigating strategies within operational contexts.

Main Results:

• The risk management framework effectively assessed bias impact and strategy effectiveness.
• Identified the latent level of risk associated with cognitive bias.
• Highlighted the contextualized, limited benefit of resource-intensive bias mitigation measures.

Conclusions:

• A risk-based approach is crucial for forensic organizations to balance bias mitigation with efficiency.
• Simple, cost-effective bias limiting measures are preferred.
• Forensic science must balance the risk of cognitive bias with the return on mitigation investments.
