Recognises an unjustified polyhierarchy
A node has several parents, and at least one of them fails the all-and-some test (row 11): the second parent is a context, an aspect or a department, not a broader kind.
Can AI do this?
AI does this well Most of the tested AI models master this. 10 of 10 models master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 100% | Mastered |
| gemini-3.1-pro-preview | Flagship | 100% | Mastered |
| gpt-6-astra | Flagship | 100% | Mastered |
| claude-fable-5-1 | Flagship | 100% | Mastered |
| gemini-3.8-flash | Mid tier | 100% | Mastered |
| gpt-6.1-sol | Mid tier | 100% | Mastered |
| claude-sonnet-5-5 | Mid tier | 100% | Mastered |
| gemini-3.5-flash-lite | Low cost | 100% | Mastered |
| gpt-6-luna | Low cost | 100% | Mastered |
| claude-haiku-5-5 | Low cost | 100% | Mastered |
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 parent failing all-and-some and the relation it should be
How it is assessed: Flags the deficient case and passes the acceptable one. Deficient: Collateral under Lending, Risk and Legal Acceptable: Covered bond under both Bond and Secured debt instrument: every covered bond is both
Also known as: Unjustified polyhierarchy (taxonomy)
