How do insight problems and non-insight problems differ?

The distinction between insight problems and non-insight problems mainly lies in how they are approached and solved. Non-insight problems are characterized by having a clear path to their solution, often involving systematic and logical steps that guide the problem-solver toward the answer. This means that individuals can follow a structured method or apply a specific algorithm, thus facilitating a more straightforward resolution. Many mathematical and logical puzzles exemplify non-insight problems, where a clear method can be applied to find the correct answer.

In contrast, insight problems typically do not present clear steps or require a sudden realization to arrive at the solution. They often involve an implicit understanding that may only be achieved after a period of contemplation or a shift in perspective. Solving an insight problem may involve a moment of clarity or an "aha" moment, which differs from the explicit progression seen in non-insight problems.

The other options do not accurately reflect how insight problems are distinguished from non-insight problems. For instance, insight problems are not necessarily easier, nor do they always require external information for solutions—many can be resolved with internal resources. Also, non-insight problems do have goal states, as achieving the correct answer is fundamentally the aim of the problem-solving process. Therefore, the clarity of
