| EEmbodimentspace · where risk lands |
Proportionate
Direct, face-to-face
Doctor treats patient in the patient's home. Both parties visible at the point of care. But the geometry is readable only for those inside it. Black Americans, rural populations, the poor, and women face exclusion or institutionalized harm. Medicine itself is primitive and often ineffective. The structure is legible. The access is not universal. The care is not modern.
|
Aligned
Single institution
Teachers know Baylor Hospital. Hospital knows the teachers. Embodiment still local and legible.
|
Attenuating
Patient enters a network
Coverage shifts from one hospital to any hospital in a community plan. The patient becomes a member of a pool, not a known individual.
|
Severed
Employer chooses insurer
Patient doesn't select the plan. Employer does, to attract labor. The patient is structurally invisible to the system that covers them.
|
Locked
Permanent architecture
Tax code makes employer-based insurance the default. The patient's invisibility becomes the system's organizing principle.
|
Mixed
Elderly and poor become visible
Seniors and low-income populations gain coverage for the first time. Half of Americans over 65 had no insurance before 1965. Embodiment improves for these populations. But the system remains third-party, fee-for-service. The patient is covered, not seen.
|
Broken
Risk-sorted pools
Commercial insurers cherry-pick healthy groups, accelerated by Medicare absorbing the elderly. The patient is a risk category, not a person. Sicker populations become structurally orphaned.
|
Formalized
Care withholding by design
HMO model explicitly incentivizes less care. The patient becomes a cost to be managed. Prior auth formalizes the presumption that care is unnecessary until proven otherwise.
|
Shielded
Regulatory vacuum
ERISA preempts state regulation of employer plans but imposes almost no federal regulation. 60% of workers in self-funded plans are beyond state consumer protections. The patient has no effective recourse.
|
Still broken
Carrier-level reform
ACA regulates what insurers must offer but doesn't change the patient's structural position. You still don't choose your insurer. The system still doesn't see you.
|
| AAnticipationtime · predictability |
Proportionate
Simple and legible
You get sick, you call the doctor, you pay a modest fee. The sequence is predictable. But "predictable" includes: the doctor may not be able to help, and if you can't pay, you don't get seen.
|
Aligned
Fixed, known cost
50 cents/month for 21 days of coverage. The terms are clear. No surprises.
|
Attenuating
Coverage terms multiply
Plans cover multiple hospitals. What's covered, what isn't, and at what cost becomes less predictable.
|
Degrading
Patient doesn't choose terms
Employer selects plan. Patient discovers coverage limits only when they need care. Anticipation becomes reactive.
|
Broken
No cap on complexity
Removal of the 5% fringe benefit cap eliminates the last structural constraint on system complexity.
|
Mixed
Guaranteed coverage, opaque costs
Seniors and the poor can anticipate that they'll be covered. But fee-for-service payment without effective cost controls creates unpredictable system-wide cost growth that drives everything after.
|
Broken
Opaque pricing
Different rates for different pools. Negotiated prices hidden from patients. No one can predict what care will cost before receiving it.
|
Weaponized
Prospective denial introduced
Prior authorization means the patient cannot predict whether care will be approved, when, or at what cost. Anticipation shifts from navigating care to navigating bureaucracy.
|
Entrenched
No state recourse
Patients in self-funded plans cannot appeal to state regulators. ERISA limits remedies to the cost of denied services, not the harm caused.
|
Attempted — unresolved
Standardized plans
ACA creates Bronze/Silver/Gold/Platinum tiers. Essential benefits defined. Some predictability restored at the plan level. But copays, deductibles, networks, and prior auth still make the care experience unpredictable.
|
| RReciprocityexchange · mutuality |
Proportionate
Direct exchange
Patient pays doctor. Doctor provides care. The exchange is legible. But "proportionate" doesn't mean fair: the exchange only exists if you can afford it. No ability to pay, no care.
|
Aligned
Shared-risk pool
Teachers pool risk. Hospital gets predictable revenue. Both sides benefit proportionately. No extraction.
|
Mostly aligned
Community-rated, nonprofit
Blue Cross plans are nonprofit, community-rated. Everyone pays the same. The risk pool is genuinely shared.
|
Decoupling
Exchange splits
Patient-employer (labor for benefits) and insurer-provider (payment for service). The care relationship is no longer the payment relationship.
|
Entrenched
Tax subsidy flows to employer
The tax benefit accrues to the employer-insurer relationship, not to the patient. Buying insurance independently is penalized.
|
Mixed
Coverage expanded, volume incentive preserved
Medicare and Medicaid extend coverage to 19 million people in Year 1. But fee-for-service is preserved at the AMA's insistence. The volume incentive that drives overtreatment and cost inflation is now federally funded.
|
Inverted
Shared risk fractures
Commercial insurers cherry-pick healthy groups, undercutting community rating. Profit extraction begins. The system takes more from those who need it most.
|
Inverted by design
"Less care = more money"
Ehrlichman's stated rationale: "All the incentives are toward less medical care, because the less care they give them, the more money they make." The system profits from withholding.
|
Immunized
Liability shield
ERISA limits remedies to cost of denied services, not damages. An insurer that wrongly denies a $5,000 procedure causing permanent disability is liable for $5,000. Extraction is protected by law.
|
Attempted — unresolved
Carrier regulation
ACA bans pre-existing condition exclusions. Medical loss ratio requires 80% to care. Subsidies. Real constraints on extraction, but the three-party architecture remains.
|
| FFeedbackinformation · signal |
Proportionate
Immediate and direct
Doctor sees whether patient improves. Patient knows what they paid. Information flows both directions. But with primitive medicine, the feedback often confirms failure, not success.
|
Aligned
Closed-loop
Single hospital, known population. Outcomes visible. If the plan isn't working, both sides know quickly.
|
Attenuating
Feedback loop lengthens
Multiple hospitals, larger pools. Outcomes aggregate into statistics. Individual signal weakens.
|
Degrading
Information asymmetry grows
Patient doesn't see the cost. Employer negotiates the plan. Provider bills the insurer. No single party holds complete information.
|
Structural
Third-party payment obscures signals
Price, quality, and outcome data flow between insurers and providers. The patient receives an EOB they can't interpret.
|
Accelerated
Volume without visibility
Federal payment flows into the system without effective cost or quality feedback mechanisms. Medicare pays what providers charge. No one is measuring whether the spending produces health. The cost feedback loop is open.
|
Broken
Hidden pricing
Each insurer negotiates different rates. The same procedure costs different amounts depending on who's paying. The system becomes structurally unreadable.
|
Corrupted
"Medical necessity" as cover
"Medical necessity" sounds clinical but functions as cover for cost decisions. The signal to the patient is clinical. The actual decision is financial. Feedback becomes systematically deceptive.
|
Suppressed
Transparency blocked
ERISA preemption has been used to block state health data transparency efforts. Self-funded plans aren't required to report claims data to states. Information asymmetry is legally protected.
|
Still broken
Complexity increases
ACA adds quality reporting for providers and insurers but does not make the system legible to patients. Prior auth, coding complexity, and appeals add procedural layers.
|
| τTensionload · where strain lands |
Proportionate
Low stakes, unevenly distributed
Medical costs are low because medicine can do little. The system absorbs its own strain. But the tension of illness itself — lost wages, disability, death — lands entirely on the individual and family. No safety net exists.
|
Aligned
Shared, bounded
Risk pooled among a known group. Costs capped (21 days). Tension stays in system.
|
Mostly aligned
Community absorbs load
Nonprofit, community-rated plans distribute tension broadly. But hospital cost inflation begins to shift load.
|
Displacing
Tension tied to employment
Job lock emerges: losing your job means losing your coverage. Health risk is now tied to employment status.
|
Amplifying
No structural cap
Unlimited tax exclusion removes the last constraint on cost growth. Rising costs absorbed invisibly through depressed wages.
|
Mixed
Federal government absorbs cost tension
The government takes on the cost burden for seniors and the poor. Financial tension for these populations decreases. But fee-for-service without cost controls creates the cost explosion that drives the HMO Act, managed care, and every subsequent attempt to contain spending.
|
Displaced
Tension lands on the sick
Healthy groups pay less. Sick populations pay more or lose access. Administrative friction displaces tension onto patients at greatest vulnerability.
|
Systematized
Friction as tension management
Prior auth becomes the system's primary cost-tension tool. The cost of every review, denial, and appeal is borne by patients and providers, not by the system that generates it.
|
Locked in
No accountability for harm
ERISA caps liability at cost of denied services. The tension of wrongful denial — lost wages, worsened conditions, disability, death — lands entirely on the patient.
|
Attempted — unresolved
Redistributed, not resolved
ACA subsidies redistribute financial tension. Medicaid expansion absorbs the poorest. Pre-existing condition ban prevents worst displacement. But administrative friction remains. Tension is managed, not metabolized.

The pre-1920 system was geometrically legible at the point of care but not equitable in access, quality, or population coverage. Medicine was primitive and often harmful. Black Americans were excluded from white hospitals and medical schools. Rural communities had little or no access to physicians. Women faced institutional exclusion from both medical practice and informed consent. Class determined whether you saw a doctor at all. The geometry was readable for those inside it, and invisible or hostile to those outside it.
This is the framework's most important distinction. Structural readability tells you whether participants can navigate the system. It does not tell you who is allowed to participate, whether the system is just, or whether the care it delivers is effective. A system can be perfectly legible and deeply exclusionary. The goal is not to return to 1920. It is to recover structural readability at modern scale, with modern medicine, for everyone — including the populations that the original geometry excluded.
Read left to right: every EARFT dimension was proportionate in the original two-party system. The degradation was cumulative and sequential, not sudden. But it was not accidental. Each historical moment served the interests of the parties who had the power to make it — hospitals, employers, insurers, corporations — and none of those parties were patients. The patient was never at the table. The system wasn't built by accident. It was built by the people who benefited from building it this way.
The system kept performing. People got insurance. Hospitals got paid. Doctors practiced medicine. Coverage expanded. But the structural conditions for trust degraded underneath. The friction described in prior authorization, denials, appeals, and administrative overhead is not a bug. It is the system doing exactly what it was built to do, which was never organized around the patient in the first place.
Medicare and Medicaid are the structural hinge. They expanded Embodiment for populations that were previously invisible — half of seniors had no insurance before 1965. But by preserving fee-for-service payment at the AMA's insistence, they created the cost explosion that drove everything after: the HMO Act (1973), ERISA (1974), managed care, prior authorization, and every subsequent layer of administrative friction. The system gained coverage and lost cost discipline in the same legislation.
Every attempted fix grabs a different dimension. Medical Homes restore Embodiment. ACOs repair Reciprocity. Price Transparency addresses Feedback. HSAs redistribute Tension. Gold card programs exempt high-approval providers from prior auth. Direct Primary Care structurally restores the original two-party geometry — but covers roughly 1% of primary care physicians. The dominant architecture has 80+ years of tax code, employer relationships, liability shields, and institutional momentum behind it. That is the Reliability Trap in action: the system performs well enough that structural alternatives cannot scale.
