Many more people die every year of pneumonia than in are killed by gun violence, but many people would expect the opposite to be true. Of course, we are more likely to hear about a homicide than we are about someone dying in a hospital with pneumonia. The tendency to expect more homicide deaths than pneumonia deaths likely results from people relying on:
a. an algorithm
b. the hindsight bias
c. functional fixedness
d. the availability heuristic
