Evidence for (8)
- All four frameworks independently converge on YES — rare cross-paradigm agreement in political-economic analysis
- Favorable base period: March 2025 was pre-Liberation Day (April 2025 tariff escalation), meaning YoY comparisons capture the full accumulated pass-through delta
- Pre-tariff inventory buffers now exhausted at ~11 months post-imposition; marginal retail price is fully tariff-inclusive in most goods categories
- Contractual pricing cycle reset (90-180 day B2B contract rollover) completed by Q1 2026, removing institutional absorption buffer
- EDLP (everyday low price) retailer norm collapse under 12+ months of sustained cost pressure — historical precedent from 2021-2022 confirms this timing
- Oligopolistic pricing power in tariff-exposed categories (electronics, apparel, consumer durables) enables full-to-over pass-through with tariff as margin-expansion cover
- Liberation Day tariff regime (10-145% on broad import categories) is an order of magnitude larger in scope than 2018-2019 Section 301 tariffs, which themselves produced near-complete pass-through per Federal Reserve research
- Third-country supply chain rerouting (Vietnam, Mexico, India) is real but insufficient for capital-intensive categories on an 11-month restructuring timeline
Evidence against (7)
- US-Iran Hormuz ceasefire introduces energy price normalization — deflationary for headline CPI, partially offsetting goods pass-through
- Austrian entrepreneurial substitution dampening: 30-40% of theoretical full pass-through absorbed by sourcing rerouting, used-goods substitution, and domestic production expansion
- Keynesian demand destruction and paradox of thrift: precautionary household saving and compressed real wages suppress services and non-tariffed category demand, partially offsetting goods inflation
- BLS measurement institution introduces downward bias via hedonic adjustments and seasonal adjustment procedures — actual pass-through may exceed what CPI registers
- Large-format retailer (Walmart, Amazon) administered pricing creates timing lags not fully captured by market-signal models
- Consumer front-loading ahead of anticipated escalation may have pulled forward demand into 2025, leaving a demand vacuum in Q1 2026
- Federal Reserve institutional credibility effects may have already tightened financial conditions enough to suppress pass-through
Reasoning chain
Base rate for headline CPI at or above 3.2% in a post-shock disinflation environment (pre-tariff trend ~2.5-3.0%) is approximately 0.38. The tariff evidence adjusts this upward across all four frameworks. The Marxist framework (weighted highest at 0.32) provides the strongest mechanistic case: oligopolistic pass-through is a structural feature of concentrated import-dependent sectors, and the class-transfer mechanism does not depend on aggregate demand remaining elevated — it operates through consumption nexus compression. Weighted framework confidence = (0.68 × 0.32) + (0.57 × 0.28) + (0.58 × 0.22) + (0.52 × 0.18) ≈ 0.60. The institutionalist framework’s identification of Q1 2026 as the contractual reset inflection point, consistent with the Austrian inventory depletion timing argument, provides strong corroborating evidence for the March print specifically being elevated rather than a prior or subsequent month. The Keynesian framework’s lower confidence (0.52) reflects the self-limiting nature of cost-push without wage accommodation and the genuine uncertainty about whether demand destruction has already begun suppressing prices in the March data. The Hormuz ceasefire is the primary downward risk: energy is the most volatile CPI component, and normalization here could drag headline below 3.2% even if core goods pass-through is complete. Confidence calibrated at 0.61 — above base rate due to framework convergence, below 0.68 due to the energy offset and BLS measurement uncertainty.
Philosophical basis
The prediction is primarily grounded in Marxist oligopoly pricing theory (pass-through as structural feature of capital's pricing power) and institutionalist contractual-cycle analysis (Q1 2026 as the inflection window where pricing norm collapse and contract resets converge). The Austrian inventory depletion mechanism provides a cross-paradigm corroboration of the timing argument. The Keynesian mark-up pricing model provides the micro-behavioral foundation for the immediate pass-through mechanism while also supplying the primary counter-argument (demand destruction and self-limiting cost-push). The unique Marxist insight — that tariffs serve as cover for margin expansion beyond cost recovery — is the mechanism most likely to push the print above rather than merely at 3.2%.
Falsification criteria
BLS CPI release on or around April 10, 2026 shows March 2026 headline CPI YoY at or above 3.2% = TRUE (prediction confirmed); below 3.2% = FALSE (prediction falsified). The BLS Consumer Price Index Summary is the authoritative source.

- 371-liberty-solidarity-pollution-conformity-reserve.md: Reserve asymmetry and class decomposition of waiting-capacity — consistent with Marxist argument that demand destruction operates on longer lag than pass-through

- 292-automation-tech-association-retaliation-petition-escalation.md: Automated retaliation defeats petition channel — analogous to how tariff pass-through mechanism defeats consumer substitution signal in concentrated markets
Brier breakdown
Post-mortem
Auto-resolved (confirmed, confidence=0.97). Evidence: The BLS released the March 2026 CPI report on April 10, 2026. Headline CPI rose 3.3% year-over-year (not seasonally adjusted), driven largely by a 21.2% surge in gasoline prices tied to the Iran conflict. Core CPI (ex-food and energy) rose 2.6% YoY. Sources: https://www.bls.gov/news.release/cpi.nr0.htm; https://www.cnbc.com/2026/04/10/cpi-inflation-report-march-2026.html; https://www.bloomberg.com/news/articles/2026-04-10/us-cpi-report-march-2026-key-takeaways-on-inflation-consumer-price-index. Reasoning: The falsification criteria specifies: headline CPI YoY at or above 3.2% = TRUE (prediction confirmed). The BLS released the March 2026 CPI on April 10, 2026 showing 3.3% YoY, which is above the 3.2% threshold. The prediction is therefore confirmed with high confidence based on multiple corroborating sources including the BLS official release and major financial news outlets.
