AI exposure: Hydrologists
Research the distribution, circulation, and physical properties of underground and surface waters; and study the form and intensity of precipitation and its rate of infiltration into the soil, movement through the earth, and return to the ocean and atmosphere.
Reading this score
computed37.6% of this occupation's weighted task load is exposed, which puts Hydrologists at the 66th percentile of 923 occupations. The capability is largely there. Its average task scores 2.4 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 25 tasks it averages 1.98 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 Prepare reports or presentations describing research results, at 80.0%. The least is Administer programs designed to ensure the proper sealing of abandoned wells, at 3.3%. A gap of 76.7% 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 27 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 25 tasks, 18 are currently banded exposed, 1 assisted and 6 untouched. For that distribution to shift materially would take cheaper ways to verify output, since the cost of checking is currently doing more to hold this work in place than the cost of producing it. The score is re-computed every quarter against a fresh capability reference, and the change is published rather than quietly applied.

What this means in practice
Where most of a role's weighted task load is exposed, the work that survives is usually the part of the job nobody wrote into the job description: deciding what should be produced rather than producing it, and being answerable for the result. The tasks lowest on this page are a better guide to where to spend your time than any general advice about the future of work.

Read this carefully. Exposure is not displacement. A high score means current AI systems can produce this work, not that anyone will stop paying a person to do it. Adoption depends on economics, regulation and inertia that this index deliberately does not model. How the score is built.
