Final answer:
Janet's surprise at meeting a female pilot is an example of representative heuristic, as she had a stereotype that most pilots are male. This cognitive bias involves unintentional stereotyping and does not involve actively seeking information to confirm a belief, which would be confirmation bias.
Step-by-step explanation:
On her way to London, Janet was invited into the cockpit to meet the pilot, Alex. She was surprised to see that Alex was a woman. This is an example of representative heuristic. Representative heuristic refers to a cognitive bias where we stereotype someone or something based on a common perception. In this case, because there's a stereotype that most pilots are male, Janet was surprised to see a female pilot, indicating she had a preconceived notion or stereotype in mind.
The availability heuristic is another cognitive bias that involves making a decision based on the most readily accessible information. However, this would not apply to Janet's surprise since it's not about the frequency or recency of her experiences, but rather about the stereotyping of a pilot's gender.
Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms one's preconceptions, and does not directly apply to this situation. Janet was not seeking information to support a belief; instead, she encountered a situation that was incongruent with her expectations.
