How to read this
This task type comes from O*NET's detailed work activities, which link similar tasks across jobs. A label applies to one job's version of the task: AI use comes from real AI conversations (Anthropic Economic Index) and robot evidence from deployments in real workplaces. "No evidence yet" may just mean the task is rare in the data. How we keep time.
