What AI-related postings ask for that others do not
The question. Within one discipline, what changes about a job posting when it mentions AI?
What it found
Evaluation language, interpretation and verification all rise. Governance barely moves, and cross-functional briefing does not move at all. The comparison is made inside a single discipline, so both arms pass through the same classifier and a misclassification lands a posting in the wrong discipline while keeping it on the correct side of the AI split.
The numbers
| Term group | AIEM element | AI | Non-AI | Lift |
|---|---|---|---|---|
| AI oversight | Discernment | 4.2% | 0.3% | 11.82 |
| handing work to a system | Delegation | 8.3% | 0.9% | 7.60 |
| evaluation language | Discernment | 42.0% | 22.9% | 1.61 |
| interpretation | Discernment | 30.1% | 15.4% | 1.48 |
| ethics, bias, responsible AI | Diligence | 7.9% | 4.0% | 1.44 |
| verification | Discernment | 36.4% | 23.9% | 1.35 |
| experimentation, pilots | Tinkering Disposition | 6.7% | 5.1% | 1.25 |
| governance | Diligence | 11.5% | 9.7% | 1.03 |
| cross-functional briefing | Description | 57.7% | 58.1% | 0.96 |
| ownership | Internal Locus of Evaluation | 19.2% | 19.0% | 0.90 |
| ambiguity | Tolerance for Ambiguity | 10.2% | 11.7% | 0.75 |
Greenhouse only. Lift is length-adjusted and is therefore smaller than the two percentages divided.
How it was computed
Greenhouse boards only, so the compared groups share a platform, a collection window and an employer pool. Lift is a Mantel-Haenszel estimate pooled over description-length quartiles, because term presence rises with posting length and AI-related postings are longer. lift_unstratified is the plain ratio published before 2026-09-11, kept for provenance only.
How to read it
Lift is adjusted for length, so it is deliberately NOT the ratio of the two percentages beside it. A group appears only where the discipline has 50+ non-AI postings and 5+ postings carry the term in each arm. Only mappings ratified against the AI Engagement Model are shown.
