Summary

Anthropic analyzed 400K Claude Code sessions and found that domain expertise is a stronger predictor of success than coding skill, with experts achieving 28-33% verified success versus 15% for novices. The study highlights that understanding the problem matters more than coding ability.

Anthropic went through about 400,000 Claude Code sessions from 235,000 users between October and April. The main finding: success tracked how well someone understood the problem, not whether they were trained to code. Across the ten largest occupations in the data, every one landed within 7 points of software engineers on success. Where the gap stays is expertise. On their strictest "verified success" measure, experts hit 28-33% versus 15% for novices. And novices give up far more often: 19% of novice sessions end abandoned, against 5-7% for everyone else. They don't really spell out how they classified "domain expertise," so take the "anyone can code now" version with some salt.
