"Educational intervention can rewire village social networks" Logical Review & Gap Analysis

This Technical Report applies the Section Zero framework (v2.0) to Papamichalis, Forastiere, Airoldi & Christakis, Educational intervention can rewire village social networks, Nature (2026), https://doi.org/10.1038/s41586-026-11154-7. It identifies seven logical gaps not raised by the authors or referees: (G1) the intervention is an unmeasured delivery bundle, with no data on health workers' conduct or recipients' uptake; (G2) outcomes are self-reported nominations; (G3) the low/high dosage cut-off is derived from the outcome data; (G4) baseline degree differs across dosage arms and change depends strongly on baseline; (G5) neighbour subgroups are selected on degree; (G6) "overall structural stability" rests on a single non-significant test; (G7) mediation assumptions are not stated. Claims are rated for reliability on the principle of direct evidence in the paper and peer review file, with a ceiling of Medium–High for a social-science study. Overall: Low–Medium; the core finding is Medium; mechanism and policy implications are unverified. This report does not replace Nature's peer review. AI-assisted drafting; the reasoning is the author's. Based on the paper, Supplementary Information, Reporting Summary, Source Data and Peer Review File only.
