Which concept describes pooling collective free time to collaborate online on projects?

• A. Cognitive dissonance
• B. Web 2.0
• C. Cognitive surplus
• D. Prosumer

Answer: (C)

Pooling collective free time to collaborate online on projects captures cognitive surplus. It’s the idea that people’s unpaid, voluntary time can be mobilized through digital platforms to create valuable public or shared goods—like Wikipedia, open‑source software, or community mapping—when technology makes collaboration easy and scalable. This concept focuses on the social value generated when everyday people contribute to collective projects, not just on the platforms themselves or on individual roles.

Web 2.0 describes the interactive, user‑driven nature of the web that enables such collaboration, but cognitive surplus specifically names the societal resource created by pooling that free time. Prosumers talk about people both consuming and producing content, which overlaps with the idea but doesn’t name the broader social pooling of time for collaborative production. Cognitive dissonance isn’t related to online collaboration at all.
