How is this measured?

The U.S. Department of Labor lists 16 responsibilities for this job (O*NET 31.0), and the split covers the 14 people in it do today. Each is scored on 4 questions: can AI do it, does it get it right, must a person sign for it, and do people need to deal with a real person. The split is weighted by how much of the job each responsibility takes up. The evidence range for the share AI could take on is 60 to 73%. One end comes from how well AI did each responsibility in real use, or a second rating where that isn't measured. The other is our figure, which also follows research across the industry.
