Compare information or figures on one record against same data on other records, or with original copy, to detect errors.

“Compare information or figures on one record against same data on other records, or with original copy, to detect errors.” is a core task performed by Proofreaders and Copy Markers. Among the occupation's 11 rated tasks, workers place it 8th by importance (#4 most important). About 94% of workers say it is relevant to their job.

This is a single occupation-specific task statement from O*NET. The figures below describe how central the task is to the job and what independent studies measure about AI and this kind of work — not a prediction that the task will be automated.

AI exposure

The OpenAI / Eloundou “GPTs are GPTs” study rates this task E1. Direct exposure — a language model could plausibly cut the time to do this task by at least half.

Exposure measures whether a model could meaningfully speed the task up — it is an estimate of overlap with model capabilities, not a measure of whether the work will be done by software. The study's intermediate score (β) for this task is 1.00. Automation potential label: T3.
