Epidemiologists
The routine layer of this job is compressing.
A substantial share of this occupation's activities overlaps with what AI already does well. Expect the routine layer to compress first, and the human-anchored layer to gain weight and value.
Where this occupation sits among all 785 measured. Bands are quintiles of the real distribution. Applicability measures task overlap with observed AI usage. It is not a probability of job loss.
What this job involves
Investigate and describe the determinants and distribution of disease, disability, or health outcomes. May develop the means for prevention and control.
Where AI overlaps this work, activity by activity
The occupation's most important work activities (O*NET weights, normalized to this set), each with its measured AI performance across 200,000 real conversations: how often AI is used for it, how well it completes it, and how much of the activity it covers.
| Work activity | Share of role | AI performance |
|---|---|---|
| Direct scientific or technical activities. | 19.6% | Not observed 0.00 |
| Coordinate activities with clients, agencies, or organizations. | 16.2% | Not observed 0.00 |
| Develop research plans or methodologies. | 14.2% | Not observed 0.00 |
| Present research or technical information. | 9.2% | High overlap 0.75 |
| Research biological or ecological phenomena. | 7.3% | Moderate 0.52 |
| Train others on operational or work procedures. | 7.0% | Not observed 0.00 |
| Write material for artistic or commercial purposes. | 6.1% | High overlap 0.71 |
| Prepare proposals or grant applications. | 5.6% | Not observed 0.00 |
| Develop operational or technical procedures or standards. | 5.0% | High overlap 0.68 |
| Supervise personnel activities. | 3.9% | Not observed 0.00 |
| Advise others on healthcare or wellness issues. | 3.6% | High overlap 0.68 |
| Teach academic or vocational subjects. | 2.2% | High overlap 0.62 |
"Not observed" is a measurement, not missing data: that activity does not meaningfully appear in the usage sample. AI performance = completion × scope × coverage (user-goal view), 0–1.
What drives this score: the biggest AI-overlapped activity in this role is present research or technical information; the most important activity AI is not observed doing is direct scientific or technical activities. The plan below is built around exactly that split.
Move first: compress the routine before it compresses you.
Next 30 days
- Take the exposed layer yourself. Your most AI-overlapped activity, Present research or technical information, is exactly what a well-tooled colleague will accelerate. Be that colleague first.
- Time-box the routine. Measure how long your repeatable tasks actually take; that's the budget AI adoption will compete against, and the time you will reinvest.
Next 90 days
- Double down where humans hold. Grow the share of your week spent on work like Direct scientific or technical activities, measured as outside AI's current reach, and take on more of it explicitly.
- Build one AI-assisted workflow end-to-end for your team and own its quality. Being the local standard-setter compounds.
The longer game
- Position at the boundary. The valuable seat in partially-exposed occupations is the translator: someone fluent in both the domain and the tools. Certifications matter less than a demonstrated workflow portfolio.
- Recheck yearly. Elevated-band occupations move: new tools shift specific activities fast. The data vintage is printed at the top of this page.
