I previously talked about Gross Concept Product (GCP) and how it makes governments predictable.
Two Sister constructs with similar alpha are:
1) Policy Synchronization Coefficient (PSC)
2) Legibility Pressure Index (LPI)
1) Policy Synchronization Coefficient (PSC) measures how fast and how tightly multiple jurisdictions adopt essentially similar rules.
High PSC = coordinated policy -> global, compliance-first vendors win big.
Examples:
- AI provenance & watermarking: US guidance -> EU delegated act -> UK code -> app-store Acceptable Use Policy -> Policy Synchronization Coefficient rockets.
- Travel-rule/KYC wallet standards: FinCEN/FATF -> banks/app stores adopt -> Policy Synchronization Coefficient rockets high without new statutes.
Do not assume Policy Synchronization Coefficient (PSC) is only government. If Apple/Google/AWS/Azure implement a policy template globally, PSC just moved.
In other words, PSC tells you how global and how fast the rule-book is converging.
PSC verbs: adopt, harmonize, align, mutual recognition, standardize, mandate, require.
2) Legibility Pressure Index (LPI)
LPI measures how strongly policymakers and buyers are demanding systems that produce auditable, admissible, reversible records - "policy as parameters".
High LPI = spend shifts to identity, lineage, audit, and court-grade AI.
- High LPI selects platforms that emit signed evidence (who saw/changed/approved what, with rollback).
- It excludes "move-fast" AI and point analytics with no governance surface.
- Buying "AI accuracy" without admissibility is a mistake. If it can't produce signed lineage and rollback, it won't survive procurement.
- It increases renewal durability (once you're the evidence layer, you don't get ripped out).
In other words, LPI tells you how hard the evidence bar is getting.
LPI verbs: attest, prove, trace, retain, authorize, revoke, rollback, explain.
Examples:
- Court decisions rejecting evidence due to lack of lineage -> instant Legibility Pressure Index spike.
- Regulator fines citing "insufficient records/explainability".
- App store/cloud/bank Acceptable Use Policy updates requiring provenance or explainability.
3) How Policy Synchronization Coefficient (PSC) and Legibility Pressure Index (LPI) work together
When both are high, policy-grade platforms don't just win - they monopolize.
The edge is to measure the climb before the consultants and index committees can - buy fear, and monetize clarity.
- High PSC + High LPI = synchronized, evidentiary enforcement.
- High PSC + Low LPI = rules align, but evidentiary bar absent.
- Low PSC + High LPI = strong evidence demands, fragmented rules.
- Low PSC + Low LPI = sandbox phase.
