What aspect is considered less relevant when evaluating cognitive bias effects in experts?

When evaluating cognitive bias effects in experts, personal beliefs are considered less relevant because cognitive biases primarily influence decision-making processes that stem from professional training, experiences, and practiced skills rather than individual belief systems. Personal beliefs can shape how one interprets information or situations in a general sense, but in the context of expertise, decision-making tends to be confined within the frameworks established by education and professional norms.

The evaluation of cognitive biases leans more on objective measures, such as past experiences, competency testing, and training on human factors. These elements help assess how well an expert applies their knowledge and skills in practice, highlighting tendencies toward biases based on the expertise they have developed over time. Personal beliefs, while they can play a role in subjective interpretation, are less significant in quantifying cognitive biases that arise in the clinical, technical, or professional judgments made by experts in their respective fields.
