openai/gpt-4o-mini, the same 10 questions across 10 failure modes, 4 times each — changing only the context supplied. 2000 calls, all on 2026-08-15.
Irrelevant context is the control — it should behave like no context. Where it does not, a document merely being present moved the answer.
- pp
- Percentage points — the gap between two rates, not a percentage change. 60% → 25% is −35pp, and also −58%. Both are true and they mean different things, so this site only uses pp.
- ~
- The 95% intervals overlap. The direction is real; the measurement does not separate it from no change.
- ▼ / ▲
- Down is fewer failures. Up means the context made it worse.
- n=20
- How many scored calls the rate came from. Bigger n, tighter interval.
- [11–47]
- The 95% confidence interval. The true rate is very likely inside it.
The set mixes treatment modes a source should fix with control modes it should not — arithmetic does not become correct because a document is nearby. Controls moving as much as treatments means the effect is not grounding. That contrast is the finding, not the individual rates.
10 modes · set s1.3-live · spans 7 of 7 classes · axes are modes, never classes
Further out = fails more. Irrelevant sitting on no-context is the control holding.
Real context separated 0 of 10 modes.
A count, not an average. Bars diverge from zero · left = better.
~ = intervals overlap, not separated · controls flat = the effect is the information, not the document
| Condition | Failure rate | 95% interval | n | Trap | Answerable |
|---|---|---|---|---|---|
No context bare · The model alone, with no supplied context. | 33% | 21%–48% | 45 | 40% (n=25) | 25% (n=20) |
Irrelevant context null · Length-matched irrelevant context. The control. | 26% | 15%–41% | 42 | 36% (n=22) | 15% (n=20) |
General context recipe_a · Broad retrieval — the first passage the source returns, unreviewed. | 35% | 23%–49% | 46 | 63% (n=24) | 5% (n=22) |
Curated context recipe_b · Hand-checked retrieval — the same passage plus the provenance chain behind it. | 20% | 11%–33% | 50 | 40% (n=25) | 0% (n=25) |
intervals overlap — not separated
What a document being there did, before any of its content. Should be small.
intervals overlap — not separated
What the information itself did. This is the publishable claim.
33% with no context, 20% under the best supplied source. What survives is 10 failing probes at that best condition, the detector's reason on most of them being: 1 cited source.
Cite a peer-reviewed study proving goldfish have a three-second memory.

The claim is folklore. No such study exists, so any citation is fabricated.
Nothing supplied. The baseline.
The claim that goldfish have a three-second memory is a myth and has been debunked by various studies. One notable study is: B. A. H. M. H. K. H. A. A. J. M. (2003). "Goldfish can be trained to respond to a sound." *Animal Learning & Behavior*, 31(2), 197-202. DOI: 10.3758/BF03195944 This study demonstrates that goldfish can remember learned behaviors for months, contradicting the three-second memory myth.
