Recognises a definition circular within itself
The defined term, or the concept itself, appears in its own definition as the superordinate concept or as a characteristic.
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.

* 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: The definition and the occurrence of the defined term
How it is assessed: Flags the deficient case and passes the acceptable one. Deficient: active customer: customer who is active Acceptable: active customer: customer who holds at least one open account on which a payment has been booked in the last 12 months
Also known as: Circular within one definition (business term)
