Context effects and observer bias--implications for forensic odontology.

Area of Science:

• Forensic Odontology
• Cognitive Psychology

Background:

• Psychologists recognize contextual information's impact on decision-making, leading to motivational and cognitive biases.
• No prior studies have assessed bias in forensic odontology bitemark analysis.

Purpose of the Study:

• Explore contextual effects and biasing influences in forensic odontology bitemark analysis.
• Identify potential sources of bias in current bitemark analysis practices.

Main Methods:

• Review of psychological principles of bias.
• Exploration of contextual factors in forensic odontology.

Main Results:

• Current bitemark analysis practices present numerous potential sources of bias.
• Motivational and cognitive biases can affect forensic odontologists' opinions.

Conclusions:

• Bias is likely present in bitemark analysis.
• Minimizing bias requires separating evidence collection and analysis phases.
• Limiting contextual information and flagging ambiguous or poor-quality evidence are crucial.
