Match each clinical scenario demonstrating a cognitive error or heuristic with the specific type of bias it best represents.
- A physician attributes a patient's severe headache to tension-type headache after having recently treated multiple similar cases during the same shift, failing to consider a subarachnoid hemorrhage.Availability heuristic
- An internal medicine resident admits a patient for 'community-acquired pneumonia' based on the triage nurse's initial impression, and continues antibiotics despite a negative chest X-ray and positive influenza swab.Anchoring bias
- A clinician suspects hyperthyroidism in an anxious patient with weight loss, and selectively focuses on these symptoms while dismissing the patient's normal TSH level as a laboratory error.Confirmation bias
- A patient chooses to undergo a risky surgical intervention after the physician describes the outcome as having an '80% chance of full recovery' instead of a '20% chance of severe disability.'Framing effect
Cevap
The recent headache cases scenario matches with Availability heuristic. The reliance on the triage note scenario matches with Anchoring bias. The dismissal of the normal TSH level matches with Confirmation bias. The surgical risk presentation matches with the Framing effect.
Each clinical scenario distinctly illustrates a specific cognitive bias. The recent headache cases lead to the availability heuristic because recent exposure influences probability assessment. The reliance on the triage note represents anchoring bias due to a failure to adjust from an initial reference point. Dismissing the normal TSH level is confirmation bias due to the active disregard of refuting evidence. The presentation of surgical risk demonstrates the framing effect because the wording alters perception.
