Final answer:
Zale's perception of car accidents being more dangerous than diabetes or cancer, despite statistical evidence to the contrary, illustrates the influence of the availability heuristic.
Step-by-step explanation:
Zale's belief that car accidents are more dangerous than illnesses such as diabetes and stomach cancer, because they are reported more frequently in the news and are more personally salient, demonstrates the availability heuristic. This cognitive bias leads individuals to overestimate the likelihood of events that are more memorable or easily recalled, even when statistical evidence indicates otherwise. In Zale's case, while diabetes and cancer cause significantly more deaths, the more vivid and frequently reported car accidents stand out in his memory, influencing his perception of risk and precautions.
