False confidence blocks a better question
If you believe you already understand something, you have little reason to examine it. A failed answer can remove that obstacle. The immediate experience feels like losing knowledge, although what has been lost may be an unjustified confidence. A more precise ignorance is sometimes an improvement.
Plato's Meno distinguishes being unable to answer from knowing that one is unable to answer. Socrates presents perplexity as potentially useful because it creates a reason to investigate. The benefit is not confusion itself. It is the change in a person's relation to the question once an easy answer no longer satisfies.
Knowing where your answer fails is more useful than rehearsing it confidently.
Let the impasse identify the next question.
Where it breaks down
Questioning can also intimidate or exhaust people. Humiliation does not establish understanding, and an endless demand for definitions can prevent worthwhile action. Aporia becomes productive only when the inquiry has a path beyond exposing someone else's uncertainty.
How it connects
Recognized uncertainty can remove the false belief that no inquiry is needed.
This idea appeared in The useful moment of not knowing, the Involves connection for October 4, 2026, which asked: Can losing confidence be a step toward understanding?

Why can perplexity help learning?
It can expose false confidence and create a reason to investigate. Exactly. The value lies in opening inquiry after an inadequate answer loses its grip.
What the sources establish
Recognizing ignorance can enable inquiry, but does not itself establish knowledge.
