Try one part without AI

Check what you understand, then bring the tool back where it helps.

Close the answer for a moment.

Can you explain why a failed source check should remain unresolved? Can you name the evidence that would justify changing your note? Could you recognize a stale decision in a handoff?

You don't need perfect wording. You need enough understanding to tell whether the next answer makes sense.

Our work has repeatedly needed someone to compare the output with the original: a table relationship, a technical word, a claim that went beyond its sources. Those corrections depended on being able to recognize what the output had changed. We haven't measured a learning gain from doing them, but the checking itself required that judgment.

Separate getting an answer from learning to judge it

A 2025 high-school mathematics experiment found that access to an unguarded GPT-4 tutor improved assisted practice performance but reduced subsequent unaided exam performance relative to the control group. A tutor designed with learning safeguards largely mitigated that harm; it did not establish an unaided improvement over the control group. Those are findings about that educational setting, not a diagnosis of adult AI users.

The distinction is useful here. Producing an answer with help and understanding the reasoning well enough to work without that help are different outcomes.

The broader learning literature also supports practicing retrieval instead of relying only on rereading. Dunlosky and colleagues' review rated practice testing and distributed practice as broadly useful across the conditions they reviewed. It doesn't validate this newsletter as a learning intervention. It gives a reason to try a small recall exercise and check it.

Choose one part of your routine. Explain it without looking. Then compare your explanation with the source and your working notes. Where did you leave out a condition? Where did a familiar phrase stand in for understanding?

You can bring AI back as a questioner: ask it to challenge your explanation or offer an unfamiliar example. Keep the source available to resolve disagreements. A model's approval is not the answer key.

This isn't a demand to do everything the hard way. If the goal is to finish a routine task, assistance may be exactly what you want. If the goal includes learning, leave yourself some work that exercises the skill you hope to keep.

Tomorrow we'll decide what deserves to stay. Include what you can explain and judge, alongside what you can produce.
