## Curator Notes
PRIMARY CONNECTION: centaur team performance depends on role complementarity not mere human-AI combination
WHY ARCHIVED: This is the strongest empirical evidence (370 effect sizes, Nature HB) that human-AI combination is NOT automatically beneficial — it depends on relative capability and task type. Directly relevant to the automation overshoot question.
## Key Facts
- Meta-analysis covered 106 experimental studies published between January 2020 and June 2023
- 370 effect sizes were analyzed across the studies
- Overall effect size: Hedges' g = -0.23 (95% CI: -0.39 to -0.07)
- Published in Nature Human Behaviour, December 2024
- Task types showing losses: deepfake classification, demand forecasting, medical diagnosis
- Task types showing gains: summarizing social media, chatbot responses, generating new content
