Multi-Scale Competency Architecture
Multi-Scale Competency Architecture (MCA) is a hierarchical organization found in biological systems where each level—ranging from molecular networks and subcellular components to cells, tissues, organs, organisms, and even swarms—possesses its own problem-solving competencies within specific action spaces. This architecture represents a fundamental principle of life, where intelligence is inherently collective and emerges from the coordinated problem-solving of competent agents across multiple scales.
Core Concepts
Hierarchical Organization
The MCA operates through multiple nested levels, each with distinct problem-solving capabilities:
- Molecular Networks - Handle metabolic and transcriptional problem spaces
- Subcellular Components - Manage organelle-specific functions
- Cells - Solve cellular-level challenges for survival and function
- Tissues - Coordinate specialized cellular activities
- Organs - Integrate tissue functions for organismal needs
- Organisms - Navigate behavioral and environmental challenges
- Swarms/Colonies - Coordinate collective action at group levels
Action Space Specialization
Each level operates within its specific action space:
- Metabolic Space - Energy management and biochemical processing
- Physiological Space - Internal regulation and homeostasis
- Transcriptional Space - Gene expression and protein synthesis
- Morphological Space - Structural organization and form
- Behavioral Space - Action selection and environmental interaction
Dynamic Interplay
The architecture is characterized by dynamic relationships across scales:
- Higher levels shape the behavioral landscape for lower levels
- Lower levels contribute capabilities and constraints to higher levels
- Bidirectional influence enables adaptive navigation toward goal states
- No top-down control required for coordinated functionality
Architectural Features
Bowtie Architecture
The MCA operates through a bowtie architecture that enables:
- Evolutionary lessons to be generalized into lineage memory engrams
- Active decoding by morphogenetic machinery for appropriate responses
- Adaptive handling of complexity, novelty, and noise at large scales
- Genomic function as a generative model rather than hardwired blueprint
Information Percolation
Key characteristic of percolation of information across scales:
- Decisions at one level influence dynamics at others
- Bioelectric circuits control morphogenesis by altering gene expression spaces
- Cross-scale coupling enables coherent system-wide responses
- Distributed intelligence emerges from local competencies
Competency Without Control
The architecture demonstrates how:
- Collective goal-seeking emerges without centralized control
- Local problem-solving contributes to global coherence
- Self-organization replaces hierarchical management
- Adaptive behavior arises from competent subsystems
Computational Applications
Neural Cellular Automata (NCAs)
Computational models inspired by MCA principles:
- Self-orchestrated developmental processes mimicking morphogenesis
- Morphostasis through collective, decentralized decision-making
- Accelerated evolution when evolving functional parameters of MCA
- Generalization to new conditions without explicit programming
Evolutionary Advantages
Research demonstrates that:
- Evolutionary processes are significantly accelerated with MCA approaches
- Functional parameter evolution outperforms direct pattern evolution
- Robust generalization emerges from multi-scale competencies
- Novel situation handling without explicit programming
Theoretical Implications
Redefinition of Intelligence
MCA challenges conventional views by showing:
- Intelligence is inherently collective, not individual
- Problem-solving occurs at all biological scales
- Cognition emerges from coordinated multi-agent activity
- Human-like cognition is just one manifestation of broader principle
Biological Intelligence
The framework suggests:
- Life’s organizing principle is distributed problem-solving
- Evolution favors multi-scale competency architectures
- Adaptation emerges from competent subsystem interactions
- Complexity is managed through hierarchical competencies

Connection to Governance Principles
Multi-Scale Competency Architecture vs Subsidiarity
Overview of the Two Concepts
| Concept | Origin / Context | Core Idea |
|---|---|---|
| Subsidiarity | Catholic social teaching (1891–present), EU law, federalist theory | Decisions must be taken at the lowest level competent to achieve the goal effectively for the common good. Higher levels only act when lower levels cannot. |
| Multi-Scale Competency Architecture (MSCA) | Systems theory, complexity science, modern heterodox governance thinking | Governance should be organized across multiple nested and overlapping scales, with each scale handling exactly the competencies it is best suited for, based on empirical capacity rather than ideology or tradition. Scales are dynamically adjustable and can be non-hierarchical or heterarchical. |
Fundamental Similarities
| Similarity | Explanation |
|---|---|
| Both are anti-centralist | Neither wants everything decided at the national or global level by default. |
| Both use competency as the key criterion | The question is always: “Which scale/level is actually able to handle this issue effectively?” |
| Both accept multiple scales of governance | Family, neighborhood, city, bioregion, nation-state, planetary institutions can all have legitimate roles. |
| Both are pragmatic rather than dogmatic | They reject “smaller is always better” and “bigger is always better” in favor of fitness-for-purpose. |
| Both support devolution by default | There is a strong presumption in favor of lower/more local scales whenever possible. |
| Both allow upward escalation when needed | If a lower scale is overwhelmed or incompetent, authority/responsibility moves up (temporarily or permanently). |
Key Differences
| Aspect | Subsidiarity | Multi-Scale Competency Architecture (MSCA) |
|---|---|---|
| Philosophical/historical root | 19th–20th century Catholic social doctrine → Christian-Democrat → EU | 21st century complexity science, systems thinking, post-progressive theory |
| View of hierarchy | Explicitly hierarchical (family → municipality → province → nation → …) with a clear chain | Can be heterarchical, networked, overlapping, or even acentric; hierarchy is only one possible pattern |
| Direction of justification | Top-down presumption with downward delegation (“higher should not do what lower can”) | Bottom-up emergence with upward integration when necessary; no privileged direction |
| Stability of scales | Scales are relatively fixed and traditionally defined (the nation-state, the Church diocese, the municipality, etc.) | Scales are dynamic, emergent, and adjustable; new scales can form or dissolve as competencies change |
| Role of tradition / ontology | Heavily informed by natural law and pre-existing social ontologies (the family is ontologically prior, etc.) | Agnostic or skeptical about ontological priority; focuses on observable capacity and feedback loops |
| Decision rule | Common good + human dignity (normative) | Systemic viability, anti-fragility, requisite variety (cybernetic/functional) |
| Typical institutional examples | Germany, Switzerland, EU, Catholic Church governance | Theoretical so far, but closest real-world approximations: Ostrom’s polycentric resource regimes, some blockchain DAOs, Rojava’s democratic confederalism (partly), certain resilient city networks |
| Attitude toward the nation-state | Generally accepts it as a natural and necessary level | Sees the nation-state as just one (often obsolescent) scale among many |
| Conflict resolution between scales | Higher level has ultimate authority if lower fails | Uses negotiation, game-theoretic mechanisms, or meta-scale arbitration; no automatic primacy |
| Time horizon & adaptability | Relatively conservative; changes slowly | Designed for rapid adaptation in high-complexity, fast-changing environments |
Simple Analogy
- Subsidiarity is like a well-run cathedral: beautiful fixed hierarchy, clear ranks (parish → diocese → national conference → Vatican), but every rank only does what the rank below cannot.
- Multi-Scale Competency Architecture is like a living coral reef or a resilient city’s response to a disaster: new nodes pop up, old ones dissolve, organisms/scales cooperate or compete based on real-time fitness, and there is no single “apex” organism that is always in charge.
Biological-Governance Integration
Parallel Principles:
- Competence-Based Distribution: MCA allocates problem-solving to the most appropriate biological scale; subsidiarity allocates decisions to the most competent governance level
- Local Autonomy: Both prioritize local problem-solving within specific action spaces while maintaining system-wide coherence
- Adaptive Responsiveness: Both systems enable adaptation to local conditions while maintaining global objectives
Biological-Governance Analogies:
- Cellular Competency ↔ Local Governance: Cells solve local problems within their action space, similar to how local governments address community-specific challenges
- Organ Integration ↔ Regional Coordination: Organs integrate tissue functions, analogous to how regional authorities coordinate local governance
- Organismal Navigation ↔ National Policy: The organism navigates behavioral space like national governments set broader strategic direction
- Swarm Intelligence ↔ Collective Action: Multi-organism coordination mirrors how multiple governance units collaborate on complex challenges
In One Sentence Each
- Subsidiarity: “Never do at a higher level what can be done well at a lower level — within a relatively stable, morally ordered hierarchy.”
- MSCA: “Let every scale do exactly what it is uniquely competent to do, and continuously reorganize the scales themselves according to empirical performance in a complex world.”
Both converge on the same practical outcome in many cases, but MSCA is more radical, future-oriented, and comfortable with fluid, non-hierarchical arrangements, whereas traditional subsidiarity remains anchored in ordered hierarchy and historical social forms.
Systems Theory Integration
Both MCA and subsidiarity exemplify how complex systems achieve coherence without centralized control:
Emergent Coordination: System-wide behavior emerges from competent local actions rather than top-down directives Self-Organization: Natural patterns of organization arise from the interaction of competent units at different scales Resilience Through Redundancy: Multiple competent units provide backup and alternative problem-solving approaches Scale-Appropriate Solutions: Problems are addressed at the scale where they can be most effectively resolved
