Summary of Human Factors in Wrongful Convictions: Confirmation Bias

Summary of Main Ideas

• Understanding Beliefs and Opinions:

  Our beliefs and opinions are shaped by our experiences and the information we process. Humans often believe they make objective judgments, but cognitive processes are influenced by biases.

• Confirmation Bias:

  Defined as the tendency to selectively gather and process information that confirms existing beliefs while disregarding contradictory evidence. This bias affects how we seek, process, and remember information.

• Impact on Criminal Justice and Forensic Science:

  Confirmation Bias can have significant implications in the Criminal Justice system, particularly in Forensic Science. An experiment demonstrated that initial exposure to contextual information (like clothing of a skeleton) can influence how forensic scientists interpret evidence.

• Cognitive Limitations:

  All humans are subject to Cognitive Limitations, which can lead to biases in decision-making. It is crucial to recognize that these biases do not imply malintent but are part of human nature.

• Minimizing Bias in Forensic Science:

  Strategies to reduce cognitive and Confirmation Bias include:

  • Shielding forensic examiners from irrelevant contextual information.
  • Ensuring that prior knowledge (like a suspect's confession) does not influence evidence evaluation.
  • Implementing procedures that help control biases throughout the forensic process.
• Holistic Approach:

  A comprehensive understanding of cognitive biases is essential, but education alone is insufficient. A Holistic Approach, including procedural changes, is necessary to minimize the effects of biases in Forensic Science.

Proposed Methodology to Minimize Bias

• Shield Forensic Examiners: Keep forensic examiners unaware of any irrelevant contextual information that could introduce bias.
• Control Information Flow: Avoid sharing prior knowledge, such as confessions, that could influence the evaluation of evidence.
• Implement Procedural Changes: Develop and adopt procedures within Forensic Science to help manage and mitigate cognitive biases.

Notable Quotes

— 01:11 — « Confirmation bias could be described as the human tendency to selectively gather and process information in order to confirm our assumptions and preconceptions whether they are true or not. »

— 02:56 — « This is not to say that forensic scientists are bad people doing bad things; our brains are subject to limitations. »

— 03:08 — « We need to take steps in order to minimize cognitive and confirmation bias in forensic science to the best of our abilities. »

— 03:52 — « It's not enough to simply just have the knowledge of cognitive biases; an educational loan will not combat cognitive biases. »
