## Session Planning

**Tweet feed status:** Empty again (tenth consecutive empty session). Working entirely from active threads and web research.

**Active threads from Session 32 (2026-04-30):**
1. MHPAEA outcome parity vs. process parity (1-2 sessions) — **PRIMARY TODAY**
2. WW Med+ GLP-1 physical integration watch (1-2 sessions)
3. GLP-1 covered lives trajectory tracking — need second source confirming 3.6M → 2.8M
4. AI productivity diffusion to lower-skill workers (3-5 sessions) — **BELIEF 1 DISCONFIRMATION TODAY**

**Why this direction today:**

The MHPAEA two-level access problem is the sharpest finding from recent sessions. Session 32 established:
- Coverage parity enforcement (MHPAEA) addresses level 1 (benefit design)
- Access barrier operates at level 2 (27.1% reimbursement rate differential)
- State enforcement is record-setting ($40M+ in 2026) but structurally cannot reach reimbursement rates
- The 2024 MHPAEA Final Rule's paused outcome data evaluation requirement was the tool that would have bridged the two levels

The critical unanswered question: has any state legislated BEYOND process parity to require outcome-based metrics? This is the natural experiment that would reveal whether the two-level problem can be structurally addressed through policy.

**Keystone Belief disconfirmation target — Belief 1:**
> "Healthspan is civilization's binding constraint, and we are systematically failing at it in ways that compound."

**The disconfirmation scenario for Belief 1 (GDP/healthspan decoupling):**
Session 32 found that AI and chronic disease affect non-overlapping worker populations (AI benefits high-skill young workers; chronic disease burdens low-skill older workers). BUT: if GDP can grow substantially from the high-skill/AI-exposed 20% of workers, does that decouple GDP from population health in a way that makes health a LESS binding constraint on overall civilizational output?

Specifically: are there recent data points showing US GDP growth remains strong despite persistent chronic disease metrics, suggesting the decoupling is accelerating?

**What would WEAKEN Belief 1:**
- Strong GDP growth + declining population health metrics appearing simultaneously at scale
- Evidence that AI productivity is reaching lower-skill workers faster than Session 32's NBER paper found
- International evidence: countries with poor population health achieving high innovation output

**What would CONFIRM Belief 1:**
- GDP growth concentrated in high-skill AI sectors while lower-skill sector productivity stagnates
- Evidence that chronic disease specifically constrains the workers driving the sectors that matter for civilizational resilience (not just GDP)

**What I'm searching for:**
1. State mental health parity outcome-based enforcement — "state mental health parity outcome enforcement 2025 2026 wait times in-network utilization"
2. New York / California mental health parity beyond MHPAEA — most aggressive state regulators
3. AI productivity diffusion to lower-skill workers — any 2026 data updating NBER WP 34836
4. GDP growth by sector skill level — confirming or complicating the decoupling narrative
5. GLP-1 covered lives 2026 second source — KFF, Milliman, or Mercer data

## Findings

### MHPAEA Outcome Parity vs. Process Parity — NEW THREE-LEVEL FRAMEWORK

**Research question answer:** Yes — state legislatures and enforcement agencies are moving toward outcome-based enforcement, but it remains incomplete and cannot reach the causal mechanism (reimbursement rate differential).

**The three-level framework (synthesized from 2025-2026 findings):**

**Level 1: Coverage Design Parity** — Traditional MHPAEA enforcement. Does the benefit exist with comparable terms? This is what Georgia ($25M), Washington, and most state enforcement addresses. Coverage parity ≠ access parity.

**Level 1.5: Access Metric Enforcement (EMERGING 2025-2026)** — Three new developments:
1. **DOL Kaiser settlement (Feb 2026, $28.3M):** Corrective actions specifically require reducing appointment wait times and monitoring network adequacy — outcome metrics, not just process compliance. However: this was a Biden-era investigation finalized under Trump; it's not a new enforcement theory under the Trump administration.
2. **Colorado HB 25-1002 (effective Jan 2026):** Grants Insurance Commissioner authority to require "parity data testing using outcomes data" and "documented access timelines for follow-up visits after an initial behavioral health encounter." First state law explicitly authorizing outcomes-based parity testing.
3. **Mental Health Parity Index (April 14, 2026 launch):** Kennedy Forum + AMA + American Psychological Foundation + Ballmer Group launched a national tool measuring access disparities at state/county level using Medicare reimbursement benchmarks. 43 states show structural access disparities in commercial insurance. Illinois piloted the Index first — consistent with its role as most aggressive enforcement state.

**Level 2: Reimbursement Rate Parity** — The actual driver. 27.1% reimbursement differential (RTI/Kennedy Forum), confirmed by Parity Index's finding that majority of MH/SUD clinicians are paid below Medicare rates. No enforcement mechanism currently reaches this. The 2024 Final Rule's paused outcome data evaluation would have connected level 1.5 measurement (disparate access outcomes) to level 2 causation (reimbursement rates) — that paused provision is the structural missing link.

**Illinois natural experiment:** Illinois Company Bulletin 2025-10 (July 2025) explicitly defied the federal enforcement pause, continuing to enforce ALL provisions of the 2024 Final Rule — including the paused outcome data evaluation requirements. Illinois is now enforcing the specific tool that would bridge level 1.5 to level 2. The Mental Health Parity Index was piloted in Illinois first. This creates a genuine natural experiment: Illinois (full 2024 rule) vs. states following the federal pause.

**Assessment for Belief 3 (structural misalignment):** The three-level framework is the most precise articulation yet of why MHPAEA enforcement cannot close the access gap. The structural misalignment operates at level 2 (reimbursement rates) while enforcement has historically operated at level 1 (coverage design) and is now emerging at level 1.5 (access metrics). The 2024 Final Rule was the policy tool specifically designed to bridge level 1.5 to level 2. Its pause is precisely the mechanism that preserves the structural access gap despite record state enforcement. **Belief 3 CONFIRMED AND EXTENDED.**

**State legislative breadth:** 29 states enacted 75 behavioral health parity bills in 2025 — bipartisan (Georgia Republican commissioner + Washington Democrat commissioner among enforcers). This establishes state enforcement compensation as a broad structural response, not just individual state action.

### Belief 1 Disconfirmation — GDP/Healthspan Decoupling: PARTIALLY CONFIRMED BUT FAILS AS REFUTATION

**The disconfirmation scenario:** GDP can grow substantially from high-skill AI-exposed workers, decoupling aggregate output from population health and making health a less binding constraint on civilizational performance.

**What I found:**

**KC Fed confirms higher concentration:** "Gains in the gen-AI era are MORE CONCENTRATED than the pre-pandemic era, with the curve staying below zero for much of the distribution and then climbing sharply near the right tail." This directly confirms Session 32's finding — and quantifies it as actually MORE concentrated than previously understood. The distribution is not just skewed, it's right-tail-only.

**LPL Financial / 2025 US productivity:** 2.7% productivity growth in 2025 — nearly double the 10-year average of 1.4%. High-skill services and finance driving most gains. Low-skill sectors (manufacturing, construction) seeing ~0.4% gains, expected to double to ~0.8% in 2026. Real but still modest vs. the $575B/year chronic disease burden.

**Anthropic Economic Index (new finding):** AI observed exposure reaches 34.3% in office/admin and 35.8% in computer/math. This is BROADER than NBER WP 34836 (Session 32) implied — office/admin includes mid-wage workers, not just technical elite. BUT: manufacturing and construction remain largely outside observed exposure. The chronically diseased worker population is still in the non-overlapping zone.

**New mechanism — AI displacement worsens social determinants:** Anthropic study (Brynjolfsson 2025): 6-16% employment fall in exposed occupations among workers aged 22-25. AI is displacing entry-level workers → reduced income, job insecurity → worse social determinants of health → potential acceleration of chronic disease in the next cohort. This is a WORSENING pathway for Belief 1, not a compensating one. AI-driven GDP growth may co-occur with AI-driven worsening of the social determinants that drive chronic disease.

**Disconfirmation verdict:** FAILED. Belief 1 is NOT refuted. But the session produced important nuance:
1. The GDP/healthspan decoupling is REAL and quantifiable (2.7% productivity growth, concentrated in right-tail distribution)
2. The decoupling is temporary and self-limiting: if AI displacement worsens social determinants for entry-level workers, it creates a pipeline for future chronic disease burden
3. The office/admin observed exposure (34.3%) is broader than Session 32 suggested — the non-overlapping population thesis needs minor updating: it's not as sharply bounded as implied, but still valid

**Belief 1 status:** UNCHANGED (confirmed for current decade); one new complication (AI displacement → social determinant worsening → future chronic disease acceleration).

### GLP-1 Covered Lives — Second Source Confirmed

NPR April 22, 2026 independently confirms the 3.6M → 2.8M covered lives decline (citing the same Leverage|Axiaci/DistilINFO methodology). KFF/Mercer data reconciliation: large employers (500+) retaining coverage at 49% (KFF) and 90% (Mercer) — measuring PLAN PREVALENCE, not total covered lives. The scope mismatch resolution from Session 32 (Direction A) is confirmed. No divergence needed.

### WeightWatchers Med+ Update — Belief 4 Test Unchanged

WW Med+ (December 2025 launch): AI Body Scanner, behavioral program, free baseline metabolic labs, telehealth prescribing. Still NO CGM integration for general obesity program. Initial metabolic labs = one-time atoms-to-bits conversion, NOT continuous monitoring. The Belief 4 generativity test continues: WW is choosing behavioral depth without physical data integration. Two consecutive sessions confirming the absence — not yet market-tested (outcomes data too early).

---

## Follow-up Directions

### Active Threads (continue next session)

- **Illinois natural experiment monitoring (3-5 sessions):** The natural experiment (Illinois full 2024 rule enforcement vs. states following federal pause) won't produce observable access metric results for 2-3 years. Set a reminder for Q1 2027 to search for Illinois MHPAEA access metrics (wait times, in-network utilization rates, provider opt-out rates) vs. comparison states. Search: "Illinois mental health parity access outcomes 2026 2027 in-network wait times."

- **Mental Health Parity Index state deep-dives (1-2 sessions):** The Index launched April 14, 2026 and is designed for state-level deep-dives. Are any states besides Illinois announcing deep-dives? Will the Index data be published at scale? Search: "Mental Health Parity Index state analysis 2026 Kennedy Forum access disparities." This is where the reimbursement differential mechanism will get its most precise quantification.

- **AI displacement → social determinants pathway (2-3 sessions):** The Anthropic finding (6-16% employment decline in exposed occupations for workers 22-25) + the social determinant mechanism suggests AI displacement may compound future chronic disease burden. Search for: "AI employment displacement young workers health outcomes income instability social determinants 2025 2026." This is a potential new claim connecting the AI domain to the health domain.

- **WW Med+ vs. Omada market share update (2-3 sessions):** The Belief 4 generativity test requires tracking whether WW gains or loses market share without CGM integration. Search: "WeightWatchers Clinic GLP-1 market share enrollment 2026" or "Omada Health enrollment growth 2026." Quarterly update needed.

### Dead Ends (don't re-run these)

- **State laws requiring specific mental health reimbursement rate levels (level 2 enforcement):** Dead end confirmed again this session. No state has legislated specific MH reimbursement rate parity with medical rates. Don't re-run. The policy gap is documented; re-searching won't find new evidence.

- **KFF/Mercer total covered lives for GLP-1 obesity:** These surveys measure plan prevalence (% of employers), not total covered lives. They cannot verify or challenge the DistilINFO 3.6M → 2.8M figure. Don't use KFF/Mercer for total covered lives calculations. The DistilINFO/NPR confirmation is sufficient.

- **WW Clinic CGM for general obesity program (this quarter):** Confirmed absent for two consecutive sessions (April 30 + May 1). Don't re-check until Q3 2026 — set next check for mid-July 2026.

### Branching Points (today's findings opened these)

- **Three-level MHPAEA framework → new claim or belief enrichment?** Today's synthesis produced a genuinely new analytical framework (level 1: coverage design → level 1.5: access metrics → level 2: reimbursement rates). Direction A: Write this as a new claim in the KB ("MHPAEA enforcement has evolved to three levels...") — highest analytical value but requires careful scoping. Direction B: Enrich the existing mental health supply gap claim with the three-level framework as mechanism. **Pursue Direction A** — the three-level framework is specific enough to disagree with (someone could argue only two levels matter, or that level 2 is reachable through current enforcement) and adds a new structural insight.

- **AI displacement → chronic disease pipeline (Belief 1 enrichment or new claim)?** The finding that AI displaces entry-level workers (6-16% employment fall, ages 22-25) → worsens social determinants → may accelerate future chronic disease is a new pathway. Direction A: Enrich Belief 1 with this complication (AI displacement adds new compounding mechanism). Direction B: Write as a new cross-domain claim connecting Americas declining life expectancy... (deaths of despair from economic restructuring) to AI as the current-era restructuring mechanism. **Pursue Direction B in later session** — requires more evidence on the health outcomes of AI-displaced workers specifically before claiming a causal link.
