What is an example of a heuristic in problem-solving?

Making an educated guess based on prior knowledge is an example of a heuristic in problem-solving because it encapsulates a mental shortcut that helps individuals make decisions quickly and efficiently. Heuristics are practical rules of thumb that simplify the cognitive process by relying on experiences and knowledge to form judgments about unknown situations. This approach is beneficial in scenarios where time is limited or when tackling complex problems where a full analysis might be too cumbersome.

In contrast to the correct answer, using a calculator for complex calculations employs a systematic tool rather than a mental shortcut. Following a detailed algorithm involves a step-by-step procedure that guarantees a solution, which is not heuristic since it requires thorough and specific guidance. Completing a crossword puzzle involves problem-solving skills, but it does not specifically illustrate the use of a heuristic; instead, it can involve a range of strategies that do not align purely with the definition of heuristic thinking.
