- What: Delete 21 byte-identical cultural theory claims from domains/entertainment/ that duplicate foundations/cultural-dynamics/. Fix domain: livingip → correct value in 204 files across all core/, foundations/, and domains/ directories. Update domain enum in schemas/claim.md and CLAUDE.md. - Why: Duplicates inflated entertainment domain (41→20 actual claims), created ambiguous wiki link resolution. domain:livingip was a migration artifact that broke any query using the domain field. 225 of 344 claims had wrong domain value. - Impact: Entertainment _map.md still references cultural-dynamics claims via wiki links — this is intentional (navigation hubs span directories).

# collective intelligence is a measurable property of group interaction structure not aggregated individual ability
|
|
|
|
Woolley, Chabris, Pentland, Hashmi, and Malone (2010) discovered that groups possess a measurable "collective intelligence" factor (c) that predicts performance across diverse tasks -- analogous to the g factor for individual intelligence. Crucially, c was only weakly correlated with average IQ (r = 0.15) or maximum IQ (r = 0.19) of group members.
|
|
|
|
What did predict c: (1) equality of conversational turn-taking (lower variance in speaking turns = higher c), (2) average social sensitivity measured by the Reading the Mind in the Eyes test, and (3) proportion of women in the group (attributed to higher average social sensitivity scores).
|
|
|
|
Pentland (2014) extended this using sociometer badges that tracked interaction patterns without content. Communication pattern alone -- measured by four "honest signals" (influence, mimicry, activity level, consistency) -- predicted team creativity and productivity. People who forge connections across teams increase organizational innovation. The flow of ideas through social networks correlates with collective intelligence independent of what those ideas contain.
|
|
|
|
Together, these findings establish that collective intelligence is an emergent structural property, not an aggregate of individual properties. Since [[intelligence is a property of networks not individuals]], this provides the empirical mechanism: it's the interaction topology, not the individual capability at each node, that determines collective performance.
|
|
|
|
For collective intelligence architecture, the implications are specific: the system must enforce something like equal turn-taking -- preventing any single agent or contributor from dominating the knowledge graph. Since [[partial connectivity produces better collective intelligence than full connectivity on complex problems because it preserves diversity]], both the amount and the pattern of information flow matter. And since [[ownership alignment turns network effects from extractive to generative]], the incentive structure should reward balanced participation, not just volume of contribution.

Relevant Notes:
|
|
- [[intelligence is a property of networks not individuals]] -- this provides the empirical mechanism for why intelligence is a network property
|
|
- [[partial connectivity produces better collective intelligence than full connectivity on complex problems because it preserves diversity]] -- the topology constraint that complements the interaction structure finding
|
|
- [[collective intelligence requires diversity as a structural precondition not a moral preference]] -- equal turn-taking mechanically produces more diverse input
|
|
- [[collective brains generate innovation through population size and interconnectedness not individual genius]] -- collective brains succeed because of network structure, and this identifies which structural features matter
