Key Characteristics:

  • Relies on mass participation
  • Increases diversity of input
  • Breaks tasks into smaller components

  • Big Idea 5 – Impact of Computing: Crowdsourcing increases access and collaboration.
  • Data Aggregation: User input improves predictive models and AI.
  • Innovations: Used in platforms like Wikipedia, Foldit, citizen science apps, and open-source development.

📺 Case Study: Foldit Gamers Solve HIV Enzyme Structure

  • Foldit is an online puzzle game that simulates protein folding.
  • Gamers, not scientists, solved the structure of an HIV-related enzyme in 10 days.
  • Demonstrates how crowdsourcing can outperform experts and AI in certain tasks.

🌐 Real-World Examples of Crowdsourcing
