The status of heuristics and cognitive biases as a source of diagnostic errors.

I am enjoying this interesting debate and I just wanted to leave my ideas
summarized in three points:


1) It is true that clinicians do not use probabilistic reasoning when doing
dx in our daily practice. We try to identify clues from patient’s story,
clinical examination and tests to suspect diseases.

2) In this setting, there is evidence (I see it everyday too) the cognitive
biases (alone or in combination with system errors - Graber 2005) explain
the most of diagnostic errors in medicine, particularly the premature
closure of diagnosis.

3) Can this situation change via accumulating knowledge and experience?


Thanks
