Each role is assessed using the AI Job Resistance Index (AIJRI), a composite score from 0 to 100 measuring how resistant a role is to AI displacement. The score is built from five dimensions: Task Resistance (how many core tasks can AI automate), Evidence Calibration (real-world adoption data), Barriers (regulatory, physical, and trust barriers protecting the role), Protective Principles (human-centric factors like empathy and judgement), and AI Growth Correlation (whether AI growth helps or hurts the role).
Roles scoring above 60 land in the Green Zone (AI-resistant), 40–60 in the Yellow Zone (needs adaptation), and below 40 in the Red Zone (high displacement risk).
