Premise Assessment
Is the claim as stated true? Four dimensions, each 0–25, sum to 100. The verdict label is derived from this score. Full rubric →
Quality and quantity of direct evidence for or against the claim — RCTs, systematic reviews, natural experiments, large cohort studies.
Levitt's repeat-challenger design and Kalla & Broockman's 49-experiment meta-analysis finding near-zero persuasive effects provide strong support for limited explanatory power.
Whether the proposed mechanism is valid and established — does the how make sense, or are there fundamental flaws in the causal logic?
The endogeneity insight (money flows to already-strong candidates) is well-established, undercutting a simple money-buys-votes causal story.
Degree of agreement among domain experts and relevant scientific or policy bodies — depth and quality of consensus, not just majority opinion.
Political scientists broadly accept the minimal-persuasion finding for general elections, while debating money's role in candidate entry and access channels the claim doesn't address.
Whether findings hold across independent studies, populations, and contexts — resistance to p-hacking and publication bias.
The minimal-effect finding replicates across Kalla & Broockman's 49 field experiments and Levitt's repeat-challenger natural experiment using different methodologies.
Individual vs. Structural
How much of the outcome is explained by structural forces versus individual agency? Four dimensions, each 0–25. Higher scores indicate stronger structural causation. Full rubric →
