Some economists have long been a bit puzzled at the astounding success of Wikipedia. Standard economic theory wouldn’t predict that such a project would thrive without some form of remuneration for the participants.
There are other projects based on peer production that seem to fit economic theory better. For instance, contributors to open source software who are seeking jobs in the computer industry can list their contributions on their resume. But what, if anything, do people get back when they contribute time to Wikipedia?
Since I regularly encourage skeptics to contribute to Wikipedia, either on their own or through organized projects like Guerrilla Skepticism, the answer to this has interested me. Understanding motivations that work would help us understand how to motivate others.
Recently some researchers at Sciences Po, Harvard Law School, and University of Strasbourg created a series of experiments to get to the heart of this problem. What they found is pretty interesting.
