Why this compare exists
State fragility taxonomy — versus thermodynamic systemic stress and capital clocks.
Desks search for "Fragile States Index" and need a clean answer on what object they are buying. This bulletin syndicates the Index-native contrast — not a trash piece, a category map.
When Fragile States Index wins
- You need a public, comparable fragility ranking for policy or research.
- The question is state fragility taxonomy, not desk capital clocks.
- You want an open annual index, not a licensed instrument.
When Entropy Index wins
- The IC needs sealed physics and Watch/Act language.
- You are allocating capital under structural stress — not mapping fragility for policy alone.
- You need sealed case clocks on one instrument.
Sealed proof anchor
Watch and Act both lit dual Crisis by March 2008 — 6 months before Lehman. — What the Index is not.
