# Nested Markov blankets enable hierarchical organization where each level minimizes its own prediction error while participating in higher-level free energy minimization

Biological systems exhibit a nested architecture where Markov blankets exist within Markov blankets at multiple scales simultaneously. A cell maintains its own statistical boundary (membrane) while being part of an organ's blanket, which itself exists within an organism's blanket, which participates in social group blankets.

This nesting enables hierarchical coordination without requiring centralized control:
- Each level can minimize free energy at its own scale using level-appropriate generative models
- Lower-level dynamics constrain but don't determine higher-level dynamics
- Higher-level predictions provide context that shapes lower-level inference
- The system maintains coherence across scales through aligned prediction error minimization

The nested structure explains how complex biological organization emerges: cells don't need to "know about" the organism's goals, they simply minimize their own free energy in an environment partially constituted by the organism's active inference. Similarly, organisms don't need explicit models of social dynamics—their individual inference naturally participates in collective patterns.

This architecture has direct implications for artificial systems: multi-agent AI architectures that mirror nested blanket organization (agent → team → collective) can achieve scale-appropriate inference where each level addresses uncertainty at its own scope while contributing to higher-level coherence.

## Evidence
- Ramstead et al. (2018) formalize nested blanket mathematics
- Empirical observation: cells within organs within organisms within social groups each maintain statistical boundaries
- Each level demonstrates autonomous inference (local free energy minimization) while participating in higher-level patterns
