Heuristic
Separate better monitoring from better performance
Knowing where the holes are is valuable. It is not the same as filling them.
When it fits
- A reflection, confidence check or learning dashboard feels more precise and you are about to treat that precision as evidence that the underlying skill improved.
When to avoid it
- The cited effect-size contrast comes from memory research. The general separation is an editorial reasoning principle, not a claim that the same numerical gap applies to work tasks.
Why it matters
Track two outcomes separately: monitoring quality and task performance. The delayed-judgment meta-analysis found a large gain in relative monitoring accuracy but only a small average gain in memory performance. That distinction matters beyond learning: a better review can show you what needs work without doing the work for you. After the diagnosis, require a separate practice, correction or task result.
An example
A mock interview rubric may reveal that your examples are weak. The rubric has improved monitoring; a later interview-style answer has to show whether the examples actually improved.
Check your result
Your review names one monitoring measure and one independent performance measure, and you do not report the first as proof of the second.
Keep this limit in mind
- The cited effect-size contrast comes from memory research. The general separation is an editorial reasoning principle, not a claim that the same numerical gap applies to work tasks.

Evidence and sources
A 2011 meta-analysis found that delaying judgments of learning substantially improved their relative accuracy compared with immediate judgments (g=0.93 across 112 effect sizes), while the corresponding average memory-performance benefit was much smaller (g=0.08 across 98 effect sizes).
The outcome is primarily relative monitoring accuracy in memory paradigms; it should not be generalized into a claim that waiting makes every confidence judgment correct.
