APSR — pp. 1-12 2026-07-29 Original Is Blood Thicker Than Water(-and-Earth)? Partisanship Geography in Imperial China and the Limits of Quantitative History YAO LIN Abstract Using Wang Anshi’s Reform as a case study, Yuhua Wang’s “Blood is Thicker Than Water” ( American Political Science Review , 2022) argues that geographically dispersed kinship networks incentivize political elites to support the building of a strong state, whereas geographically concentrated kinship networks undermine state building. In this article, I improve the sample with the help of additional historical records and show that the reported correlation fails to replicate when either the control issue or the outlier issue is considered. I then propose two alternative hypotheses on the role of kinship network dispersal in Wang Anshi’s Reform, based on two common explanations of its partisanship geography in Chinese historical scholarship, that is, status competition and policy adaptiveness. After examining those hypotheses respectively, I reflect on the limits of quantitative history that this case illustrates.

APSR — pp. 1-9 2026-07-28 Original Still Instrumentally Inclusive STUART J. TURNBULL-DUGARTE, ALBERTO LÓPEZ ORTEGA Abstract Do individuals in Western democracies shift their views on LGBT+ inclusion when exposed to opposition from Muslim out-groups? And is this “homonationalist” responsiveness stronger among anti-immigration individuals? Our article “Instrumentally inclusive [...]” addressed these questions using representative data from Britain (Study 1) and crowd-sourced data from Spain (Study 2). We revisit Study 2 in response to concerns about post-stratification weighting a convenience sample and erroneously inconsistent use of robust standard errors. Varying population reference parameters, weight caps, variance estimators, subgroup definitions, and covariate adjustments, we find strong support for the original findings. Neither reasonable alternative weighting schemes nor corrected variance estimators substantively change the results. In fact, the originally published point estimates are equal to or smaller than the median across alternative specifications. Consistent with the Article, we find that treatment increases support for LGBT+ inclusion in Spain, without consistent identifiable variation by immigration attitudes.
