Match each clinical scenario demonstrating a diagnostic error to the specific cognitive bias it best represents.
- A surgeon focuses entirely on a referral diagnosis of 'rule out appendicitis' for a patient's abdominal pain and schedules surgery, failing to notice a pathognomonic dermatomal rash indicating herpes zoster.Anchoring bias
- A clinician is convinced a patient's weight loss and palpitations are due to hyperthyroidism, citing a mild tremor as proof while actively disregarding a normal TSH level and a positive urine drug screen for stimulants.Confirmation bias
- After recently treating two severe cases of rare fungal meningitis, an infectious disease specialist immediately suspects the same diagnosis in a young, healthy college student presenting with classic signs of acute bacterial meningitis.Availability heuristic
- A transferring facility describes a patient as having 'end-stage dementia with permanent confusion.' Consequently, the receiving medical team attributes the patient's acute agitation to baseline status without evaluating for a new underlying infection.Framing effect
Answer
The correct matches are: the surgeon scenario represents Anchoring bias, the hyperthyroidism scenario represents Confirmation bias, the meningitis scenario represents the Availability heuristic, and the dementia transfer scenario represents the Framing effect.
Each scenario describes a classic presentation of a distinct cognitive bias. Anchoring involves sticking rigidly to an initial diagnosis or piece of information. Confirmation bias involves seeking and highlighting data that supports a hypothesis while actively ignoring refuting data. The availability heuristic involves judging probability based on recent or highly memorable events. The framing effect occurs when the presentation, wording, or context of information heavily influences decision-making.
