Can the motivations that drive individual behavior towards online collaborative production be explained entirely by enlightened self-interest? More generally, in this new culture around collaboration and online participation, what motivates people to share? This was (essentially) the question posed by a research associate of Yochai Benkler at Clay Shirky's talk at Harvard last week. Enlightened self-interest can be defined as individual motivations that are neither purely selfish nor altruistic, but are ultimately based in the knowledge that helping the group might ultimately help oneself. This is exemplified in the shopkeeper who is only generous to customers so that they might ultimately profit in the long run through future business. Can this alone explain why people cooperate online?
