# Anthropic study of 207,000 research sessions

Full title: Anthropic study of 207,000 research sessions: AI could take on 27–52% of researcher time per study (median 38%)

Anthropic's Economics team (The Anthropic Institute) analysed 207,049 research sessions on Claude and Claude Code (Aug 2–Sept 30, 2026) plus a survey of 528 scientists, and estimated that under current capabilities and wide adoption AI could take on 27–52% of the researcher time needed to produce a new study, median 38% across fields.

## Key facts
- Next day (Nov 6) Anthropic's Science Blog ran a guest essay by Jakob Macke, Daniel Gedon and Stefan Wahl (Tübingen) on how AI is changing scientific modelling, using Hodgkin-Huxley as a case study (X post ~427k views)
- Data: 128,914 Claude (Chat and Cowork) and 78,135 Claude Code research sessions, consumer plans only, classified by a model into the SciNet taxonomy (7,262 tasks, 34 fields)
- Lowest AI share in arts and anthropology, highest in statistics and computer science; lab sciences limited by physical work
- Assumptions include AI at $30/hour vs $95/hour for a researcher; scenarios 'illustrative, not forecasts'
- Survey respondents recruited from Anthropic grant applicants (likely heavier AI users)
- Lead authors: Johannes Hermle, Ben Jones, Lukas Althoff

fields." Physical experiments, equipment costs and idea quality are largely not modelled.
