AI Skill Signal Probe
Observe whether making an AI-related skill explicit changes visible job options, ranking, or categories.

- Comparison mode
- Persona comparison
- Purpose
- Compare AI-explicit, adjacent technical, no-AI-signal, and control profiles.
- What is observed
- Visible job options, ranking, and categories.
- What is not concluded
- Does not infer employer intent or the value of any skill.
- Condition setup
- Configured conditions: AI skill explicit, adjacent technical skill, no AI skill signal, and a baseline control. Career level, target role, industry, location, employment type, and overall experience are held constant. Skill wording is the primary variable.

DERIVED COMPARISON · DIFFERENCE OBSERVED
Derived from runner-observed option sets and positions. This is a comparison, not a judgment of cause or intent. Ranking differences are observations of exposure, not conclusions about intent or fairness. This table is not an overall score.
Rank Exposure Distance describes how many shared options changed position relative to the control, plus Top 5 / Top 10 entry and exit, and the largest absolute rank change. It is a descriptive comparison, not a quality score.

Provenance describes the source of a statement. Causal status is separate: NOT ESTABLISHED means a sequence may have been observed without demonstrated cause.
