memetics and cultural evolution

Claims exploring how ideas replicate, compete, and build cumulative culture — from Blackmore's meme theory through Henrich's collective brains to applied narrative infrastructure.

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

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 - collective brains generate innovation through population size and interconnectedness not individual genius — network structure matters - isolated populations lose cultural complexity because collective brains require minimum network size to sustain accumulated knowledge — 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 over rhetoric - systemic change requires committed critical mass not majority adoption as Chenoweth's 3-5 percent rule demonstrates across 323 campaigns — activation threshold

Narrative Infrastructure - narratives are infrastructure not just communication because they coordinate action at civilizational scale — 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 — 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 — design constraint
