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.
Dharmapala, Foley & Forbes's 2004 repatriation holiday analysis found no domestic investment increase, and TCJA-era studies found investment tracking pre-existing demand trends rather than the tax cut itself.
Whether the proposed mechanism is valid and established — does the how make sense, or are there fundamental flaws in the causal logic?
The distinction between rate cuts (weak investment link) and targeted expensing provisions (Zwick & Mahon find strong bonus-depreciation effects) is well-established, explaining the inconsistency the claim identifies.
Degree of agreement among domain experts and relevant scientific or policy bodies — depth and quality of consensus, not just majority opinion.
Public finance economists broadly accept that statutory rate cuts show weaker investment effects than targeted provisions, following the repatriation holiday's clean test.
Whether findings hold across independent studies, populations, and contexts — resistance to p-hacking and publication bias.
The rate-cuts-don't-reliably-move-investment finding replicates across the 2004 repatriation holiday and TCJA 2017 event studies using different natural experiments.
Individual vs. Structural
