AI exposure: Historians

47.7% of this occupation's weighted task load is exposed, which puts Historians at the 86th percentile of 923 occupations. The capability is largely there. Its average task scores 2.9 out of 4 on what a current system can produce, and the frictions that hold other jobs in place are comparatively weak here.

What holds the line here is context. Across this occupation's 21 tasks it averages 1.94 out of 3, the highest of the five friction dimensions. In plain terms, the work depends on knowledge the model cannot hold. Much of this job runs on things that were never written down: what this particular organisation does, what happened last week, what the person across the table actually meant. That context is the barrier, and it erodes as systems are given more access.

The most exposed thing this job does is Edit historical society publications, at 93.3%. The least is Conserve and preserve manuscripts, records, and other artifacts, at 0.0%. A gap of 93.3% between two parts of the same job is the reason this index publishes at task level. An occupation-wide number would have hidden both.

Within life, physical and social science occupations, this one is more exposed than most. The median across the 60 roles in the group is 35.8%, and only 4 of them score higher than this. Occupational families are not uniform, and the spread inside them is often wider than the gap between them.

What would move this score. Of 21 tasks, 19 are currently banded exposed, 0 assisted and 2 untouched. For that distribution to shift materially would take systems being given deeper access to the organisation's own records and history, which is already happening. The score is re-computed every quarter against a fresh capability reference, and the change is published rather than quietly applied.
