# METR

## Profile
An AI research organization that conducts rigorous evaluations of frontier model capabilities and risks.

## Relevance
METR ran the **randomized controlled trial** showing that AI tools initially made experienced developers **19% slower** — empirical anchor for [[claim-ai-slows-devs]] and the [[concept-j-curve-productivity|J-Curve]].

## Verification
The METR study is publicly cited and forms one of the more rigorous data points on AI productivity in real engineering work. Their finding that developers self-reported a 24% speedup while actually being 19% slower has become a touchstone of the productivity-debate literature.
