Civilizational dynamics in five coordinates
We treat a country as a long-run state–society system and track five slow variables:
- E – Energy & productive capacity
- D – Structural burden (debt, ageing, obligations)
- M – Meaning field cohesion (trust, polarisation)
- Ac – Adaptive capacity (governance, innovation)
- Lc – Lock-in (rigidity of institutions & spending)
These are combined into a capacity curve C(t), a burden curve B(t) and a structural imbalance index Imbalance(t) = B(t) − C(t).
