Why is diagnosis not probabilistic in clinical-pathological conference (CPCs): Point

The main reason a probabilistic approach is not employed for diagnosis in clinical-pathological conferences (CPCs) is the notion of prior probability as prior evidence in it which encourages failure to suspect diseases with atypical presentations thus increasing diagnostic errors. In addition, errors in some individual persons are a necessary consequence of employing a probabilistic approach for inference as is seen in its use in the life insurance business. This consequence is in conflict with the aim in diagnosis of determining a disease correctly in every individual patient which also leads to a probabilistic approach not being employed in CPCs.
