extraction_notes: "Extracted 7 claims and 7 enrichments. Core finding is the inverted-U relationship across multiple dimensions (connectivity, diversity, AI integration, personality traits). Five degradation mechanisms identified: bias amplification, motivation erosion, social bond disruption, skill atrophy, homogenization. Multiplex network framework provides structural model but review explicitly notes absence of comprehensive predictive theory. High-impact source (Cell Press) with direct relevance to collective intelligence architecture design."

## Content

Comprehensive review of how AI enhances and degrades collective intelligence. Key framework: multiplex network model (cognition/physical/information layers).

**Core Finding: Inverted-U Relationships**
Multiple dimensions show inverted-U curves:
- Connectivity vs. performance: optimal number of connections, after which effect reverses
- Cognitive diversity vs. performance: curvilinear inverted U-shape
- AI integration level: too little = no enhancement, too much = homogenization/atrophy
- Personality traits vs. teamwork: extraversion, agreeableness show inverted-U with contribution

**Enhancement Conditions:**
- Task complexity (complex tasks benefit more from diverse teams)
- Decentralized communication and equal participation
- Appropriately calibrated trust (knowing when to trust AI)
- Deep-level diversity (openness, emotional stability)

**Degradation Mechanisms:**
- Bias amplification: AI + biased data → "doubly biased decisions"
- Motivation erosion: humans lose "competitive drive" when working with AI
- Social bond disruption: AI relationships increase loneliness
- Skill atrophy: over-reliance on AI advice
- Homogenization: clustering algorithms "reduce solution space," suppressing minority viewpoints

**Evidence Cited:**
- Citizen scientist retention problem: AI deployment reduced volunteer participation, degrading system performance
- Google Flu paradox: data-driven tool initially accurate became unreliable
- Gender-diverse teams outperformed on complex tasks (under low time pressure)

**Multiplex Network Framework:**
- Three layers: cognition, physical, information
- Intra-layer and inter-layer links
- Nodes = humans (varying in surface/deep-level diversity) + AI agents (varying in functionality/anthropomorphism)
- Collective intelligence emerges through bottom-up (aggregation) and top-down (norms, structures) processes

**Major Gap:** No "comprehensive theoretical framework" explaining when AI-CI systems succeed or fail.

## Agent Notes
**Why this matters:** The inverted-U relationship is the formal finding our KB is missing. It explains why more AI ≠ better collective intelligence, and it connects to the Google/MIT baseline paradox (coordination hurts above 45% accuracy).
**What surprised me:** The motivation erosion finding. If AI reduces human "competitive drive," this is an alignment problem UPSTREAM of technical alignment — humans disengage before the alignment mechanism can work.
**What I expected but didn't find:** No formal model of the inverted-U curve (what determines the peak?). No connection to active inference framework. No analysis of which AI architectures produce enhancement vs. degradation.
**KB connections:** [[collective intelligence is a measurable property of group interaction structure not aggregated individual ability]] — confirmed and extended. [[AI is collapsing the knowledge-producing communities it depends on]] — the motivation erosion finding is a specific mechanism for this collapse. [[collective intelligence requires diversity as a structural precondition not a moral preference]] — confirmed by inverted-U.
**Extraction hints:** Extract claims about: (1) inverted-U relationship, (2) degradation mechanisms (homogenization, skill atrophy, motivation erosion), (3) conditions for enhancement vs. degradation, (4) absence of comprehensive framework.
**Context:** Published in Cell Press journal Patterns — high-impact venue for interdisciplinary review.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: collective intelligence is a measurable property of group interaction structure not aggregated individual ability
WHY ARCHIVED: The inverted-U finding is the most important formal result for our collective architecture — it means we need to be at the right level of AI integration, not maximum
EXTRACTION HINT: Focus on the inverted-U relationships (at least 4 independent dimensions), the degradation mechanisms, and the gap (no comprehensive framework)


## Key Facts
- Google Flu paradox: data-driven tool initially accurate became unreliable
- Gender-diverse teams outperformed on complex tasks under low time pressure
- Citizen scientist retention declined after AI deployment
- Review published in Patterns (Cell Press journal) 2024
- Framework identifies three network layers: cognition, physical, information
- Five degradation mechanisms: bias amplification, motivation erosion, social bond disruption, skill atrophy, homogenization
- Four dimensions show inverted-U curves: connectivity, cognitive diversity, AI integration level, personality traits
