# Cultural Dynamics — How Ideas Spread and Coordinate

Cultural evolution, memetics, master narrative theory, and paradigm shifts explain how ideas replicate, how coordination narratives form and dissolve, and why the current narrative infrastructure is failing. This determines whether any coordination solution can propagate at civilizational scale.

## Memetic Foundations
- [[true imitation is the threshold capacity that creates a second replicator because only faithful copying of behaviors enables cumulative cultural evolution]] — the origin of culture
- [[cultural evolution decoupled from biological evolution and now outpaces it by orders of magnitude]] — the great decoupling
- [[meme propagation selects for simplicity novelty and conformity pressure rather than truth or utility]] — why truth doesn't win automatically
- [[memeplexes survive by combining mutually reinforcing memes that protect each other from external challenge through untestability threats and identity attachment]] — how idea-systems persist
- [[the strongest memeplexes align individual incentive with collective behavior creating self-validating feedback loops]] — the design target for LivingIP

## Community Formation
- [[human social cognition caps meaningful relationships at approximately 150 because neocortex size constrains the number of individuals whose behavior and relationships can be tracked]] — the cognitive ceiling on group size
- [[social capital erodes when associational life declines because trust generalized reciprocity and civic norms are produced by repeated face-to-face interaction in voluntary organizations not by individual virtue]] — how trust infrastructure is built and depleted
- [[collective action fails by default because rational individuals free-ride on group efforts when they cannot be excluded from benefits regardless of contribution]] — why groups don't naturally act in their shared interest
- [[weak ties bridge otherwise disconnected clusters enabling information flow and opportunity access that strong ties within clusters cannot provide]] — the structural role of acquaintances

## Selfplex and Identity
- [[the self is a memeplex that persists because memes attached to a personal identity get copied more reliably than free-floating ideas]] — identity as replicator strategy
- [[identity-protective cognition causes people to reject evidence that threatens their group identity even when they have the cognitive capacity to evaluate it correctly]] — why smarter people aren't less biased

## Propagation Dynamics
- [[ideological adoption is a complex contagion requiring multiple reinforcing exposures from trusted sources not simple viral spread through weak ties]] — why ideas don't go viral like tweets
- [[complex ideas propagate with higher fidelity through personal interaction than mass media because nuance requires bidirectional communication]] — fidelity vs reach tradeoff
- [[collective brains generate innovation through population size and interconnectedness not individual genius]] — why network structure matters
- [[isolated populations lose cultural complexity because collective brains require minimum network size to sustain accumulated knowledge]] — the minimum viable network

## Applied Memetics
- [[metaphor reframing is more powerful than argument because it changes which conclusions feel natural without requiring persuasion]] — the most effective tool
- [[institutional infrastructure propagates memes more durably than rhetoric because measurement tools make concepts real to organizations]] — infrastructure > rhetoric
- [[systemic change requires committed critical mass not majority adoption as Chenoweth's 3-5 percent rule demonstrates across 323 campaigns]] — the activation threshold
- [[history is shaped by coordinated minorities with clear purpose not by majorities]] — why small groups matter

## Narrative Infrastructure
- [[narratives are infrastructure not just communication because they coordinate action at civilizational scale]] — narratives as coordination technology
- [[master narrative crisis is a design window not a catastrophe because the interval between constellations is when deliberate narrative architecture has maximum leverage]] — the current opportunity
- [[technology creates interconnection but not shared meaning which is the precise gap that produces civilizational coordination failure]] — the diagnosis
- [[the internet as cognitive environment structurally opposes master narrative formation because it produces differential context where print produced simultaneity]] — why internet doesn't fix it
- [[no designed master narrative has achieved organic adoption at civilizational scale suggesting coordination narratives must emerge from shared crisis not deliberate construction]] — the design constraint

## The Rationality Fiction
- [[civilization was built on the false assumption that humans are rational individuals]] — the expired fiction
- [[humans are the minimum viable intelligence for cultural evolution not the pinnacle of cognition]] — the humbling reframe
- [[every cognitive tool humanity built is scaffolding compensating for near-minimum biological capability]] — scaffolding all the way down
