Final answer:
We tend to rely on heuristics, which are mental shortcuts, when our cognitive resources are depleted (C). This typically occurs during situations with information overload, limited decision-making time, or when decisions are considered unimportant.
Step-by-step explanation:
We tend to rely on heuristics when our cognitive resources are depleted. Kahneman (2013) describes heuristics as mental shortcuts or rules of thumb for drawing inferences, which are largely unconscious, automated, and efficient but not always correct. We use heuristics to bypass complex problem-solving methods when:
We are confronted with too much information.
The time to make a decision is limited.
The decision to be made is seen as unimportant.
We have access to very little information.
An appropriate heuristic comes to mind.
Therefore, the answer to the question is C. our cognitive resources are depleted. When faced with a novel or complex situation, like navigating a new city, we must engage in rational thinking, which demands more cognitive resources than routine or familiar tasks.
