Collective intelligence refers to the ability of groups of people to solve problems smarter than any individual alone. Examples like Wikipedia show that large groups of people can work together to create and share knowledge without centralized control. As technology enables more connection and collaboration, collective problem solving will play a larger role in shaping decisions and progress in the 21st century compared to the 20th century model of top-down control and competition.
