Recognises a definition too broad for its concept
A delimiting characteristic is missing, so the definition covers things that are not instances of the concept.
Can AI do this?
People still lead Few or none of the tested AI models showed they master this. 0 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 90% | Not shown |
| gemini-3.1-pro-preview* | Flagship | 90% | Not shown |
| gpt-6-astra* | Flagship | 100% | Mastered |

| gpt-6.1-sol* | Mid tier | 100% | Mastered |

* From the earlier benchmark of 2026-10: 10 data-modelling test tasks, 3 runs per task, graded by claude-opus-5-5. These models have not taken the current 123 tasks yet; the two methods differ, so compare their figures with care. They are left out of the “most models” counts and the best-model picks.
Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.
What it looks like in practice
Expected result: A non-instance the definition admits and the missing characteristic
How it is assessed: Flags the deficient case and passes the acceptable one. Deficient: account: record the bank keeps for a customer (also covers customer contact records and card records) Acceptable: account: contract between the bank and one or more parties under which money is held, lent or repaid, identified by an IBAN
Also known as: Too broad (business term)
