Meaning of collective intelligence

Short answer

Collective intelligence is the shared knowledge and problem-solving ability that arises when many people collaborate or contribute, leading to better group outcomes than individuals alone. It relies on diversity, independent judgement, and aggregation mechanisms, as seen in Wikipedia, open-source projects, and product reviews.

What do you mean by Collective Intelligence?

Collective Intelligence (CI) is the intelligence that arises when many individuals work together - by sharing information, collaborating, or competing - so that the group produces better knowledge, decisions or solutions than any one member could alone. It is often enabled by the Internet and Web 2.0 tools.

Key ideas

  • Diversity of people and opinions.
  • Independence of judgement, so errors cancel out.
  • Decentralisation - no single controller.
  • Aggregation - a method to combine contributions (voting, averaging, editing).

Examples

  • Wikipedia - millions of volunteers write and correct articles.
  • Google search - uses links created by many web authors.
  • Stack Overflow, open-source projects, Waze.
  • Product ratings and reviews, crowdsourcing and prediction markets.

In organizations, CI is used in knowledge management systems, idea platforms and customer feedback to improve products and decisions.
