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.
Colburn & Aldern's cross-metro analysis and the HUD Family Options Study's RCT finding that rent subsidies halved shelter stays provide strong causal support.
Whether the proposed mechanism is valid and established — does the how make sense, or are there fundamental flaws in the causal logic?
The musical-chairs mechanism (Quigley & Raphael) is well-validated: individual vulnerability predicts who becomes homeless, while housing market conditions predict the rate at which a city produces homelessness.
Degree of agreement among domain experts and relevant scientific or policy bodies — depth and quality of consensus, not just majority opinion.
Broad agreement among housing researchers on this reconciliation between individual risk factors and structural rate determinants.
Whether findings hold across independent studies, populations, and contexts — resistance to p-hacking and publication bias.
The housing-cost-drives-rate finding replicates across Colburn & Aldern's national cross-metro comparison and the HUD Family Options Study's randomized intervention.
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 →
