Which of the following is an example of a choice heuristic?

The example of a choice heuristic in this question is selecting a product based on recommendations from an expert. A choice heuristic is a mental shortcut that simplifies decision-making, allowing consumers to make quicker choices without extensive evaluation of all available information. When individuals rely on expert recommendations, they trust the knowledge and experience of that expert, which serves to reduce the cognitive load associated with evaluating every product feature personally. This approach helps consumers feel more confident in their decisions by leveraging the expertise of others, effectively streamlining their choice process.

In contrast, memorizing all types of products involves detailed information processing, which is contrary to the quick decision-making principles of a heuristic. Returning items for a refund speaks to post-purchase behavior rather than the decision-making process itself. Researching extensively online before making a purchase indicates a thorough evaluation of information, which again does not align with the simplicity of employing a heuristic but rather reflects a comprehensive decision-making strategy.
