Explains the common causes of data quality issues
Lack of leadership and governance, data entry processes, data processing functions (wrong assumptions about sources, stale business rules, changed structures), system design (unenforced constraints, weak modelling), and issues fixed by hand without their cause addressed.
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 | 72% | Not shown |
| gemini-3.5-flash-lite | Low cost | 70% | Not shown |
| gpt-6-luna | Low cost | 70% | Not shown |
| claude-haiku-5-5 | Low cost | 70% | Not shown |
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: Lack of leadership and governance, data entry processes, data processing functions (wrong assumptions about sources, stale business rules, changed structures), system design (unenforced constraints, weak modelling), and issues fixed by hand without their cause addressed.
