You develop a very runny nose, see spots when you stand up quickly, have repeated sudden swelling of your hands that goes away in 15 minutes, constantly blink, and have an elevated temperature. You go to your doctor, who, finding a diagnosis in a big reference book, excitedly announces that you must have Tufted Yellow Screeching Parrot Fever because you show all its symptoms. The doctor is ignoring that there are no tufted yellow screeching parrots (which cause the disease) in Minnesota and there has never been a reported case of that rare disease in the state. She is using what cognitive shortcut to diagnose you?
A. The representativeness heuristic.
B. The availability heuristic.
C. The sunk-cost effect.
D. The confirmation bias.
