# James Surowiecki ![[50 Resources/51 Attachments/51.03 Public/2026-05-04 James Surowiecki.jpg|400]] James Surowiecki (born 1967) is an American journalist and author, best known for *The Wisdom of Crowds* (2004). He wrote the business column for The New Yorker from 2000 to 2017. His book popularized the idea that under the right conditions, groups of people can make better decisions than even expert individuals. The aggregation of diverse, independent opinions often produces surprisingly accurate results—from guessing the weight of an ox to predicting election outcomes. Surowiecki identified four conditions for crowd wisdom: diversity of opinion, independence (people's views aren't determined by others), decentralization (people draw on local knowledge), and aggregation (a mechanism to combine judgments). When these conditions fail—through groupthink, social influence, or homogeneity—crowds become "mad" rather than wise. His work influenced prediction markets, crowdsourcing, and collective decision-making in organizations. It complements but differs from [[Pierre Lévy]]'s collective intelligence: Surowiecki emphasizes aggregation of independent judgments, Lévy emphasizes active collaboration. ## The Wisdom of Crowds ``` ┌─────────────────────────────────────────────────────────────┐ │ THE WISDOM OF CROWDS │ │ (James Surowiecki) │ ├─────────────────────────────────────────────────────────────┤ │ │ │ FOUR CONDITIONS FOR CROWD WISDOM: │ │ │ │ ┌─────────────────┐ ┌─────────────────┐ │ │ │ DIVERSITY │ │ INDEPENDENCE │ │ │ │ Different │ │ Opinions not │ │ │ │ perspectives │ │ influenced by │ │ │ │ and information │ │ others │ │ │ └─────────────────┘ └─────────────────┘ │ │ │ │ ┌─────────────────┐ ┌─────────────────┐ │ │ │DECENTRALIZATION │ │ AGGREGATION │ │ │ │ Local knowledge │ │ Mechanism to │ │ │ │ and │ │ combine │ │ │ │ specialization │ │ judgments │ │ │ └─────────────────┘ └─────────────────┘ │ │ │ │ When conditions fail → Groupthink, Herding, Cascades │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ## Key Concepts | Concept | Description | |---------|-------------| | **Wisdom of crowds** | Groups can outperform experts | | **Diversity** | Different perspectives improve accuracy | | **Independence** | Avoid social influence on judgments | | **Decentralization** | Leverage distributed knowledge | | **Aggregation** | Mechanisms to combine opinions | ## Types of Collective Problems | Problem Type | Example | |--------------|---------| | **Cognition** | "How many jellybeans?" | | **Coordination** | Traffic, markets | | **Cooperation** | Paying taxes, voting | ## When Crowds Fail | Failure Mode | Description | |--------------|-------------| | **Homogeneity** | Too similar perspectives | | **Centralization** | Top-down control | | **Social influence** | Copying others' opinions | | **Information cascades** | Following the herd | | **Groupthink** | Consensus over accuracy | ## Applications | Domain | Application | |--------|-------------| | **Prediction markets** | Betting markets for forecasting | | **Crowdsourcing** | Distributed problem-solving | | **Decision-making** | Diverse input before deciding | | **Estimation** | Averaging guesses | | **Open source** | Distributed development | ## Surowiecki vs Lévy | Aspect | Surowiecki | [[Pierre Lévy]] | |--------|------------|-----------------| | **Model** | Statistical aggregation | Collaborative creation | | **Process** | Independent → combine | Interactive → co-create | | **Metaphor** | Voting, markets | Wiki, dialogue | | **Focus** | Accuracy | Knowledge building | ## Quotes <!-- QueryToSerialize: LIST FROM #type/quote AND [[James Surowiecki]] WHERE public_note = true SORT file.name ASC --> ## Books <!-- QueryToSerialize: LIST FROM #type/book AND [[James Surowiecki]] WHERE public_note = true SORT file.name ASC --> ## References - Surowiecki, J.
