We are a species that depend on one another. Scientists theorize humans have specially adapted neurons that help us feel what others feel, providing evidence that we survive through our empathy for others. We’re meant to be part of a tribe and our brains seek out rewards that make us feel accepted, important, attractive, and included.
Many of our institutions and industries are built around this need for social reinforcement. From civic and religious groups to spectator sports, the need to feel social connectedness informs our values and drives much of how we spend our time. Communication technology in particular has given rise to a long history of companies that have provided better ways of delivering what I call, “rewards of the tribe.”
However, it’s not only the reward we seek. Variability also keeps us engaged. From the telegraph to email, products that connect us are highly valued, but those that invoke an element of surprise are even more so. Recently, the explosion of Web technologies that cater to our insatiable search for validation provide clear examples of the tremendous appeal of the promise of social reward.
The endless search for rewards of the tribe, and the variability that often comes with it, are key components of the Web’s largest technical question and answer site, Stack Overflow. As with other user-generated sites like Quora, Wikipedia, and YouTube, all of Stack Overflow’s content is created voluntarily by its members. In Stack Overflow’s case, over 5,000 questions are posted and answered daily, all of which cost nothing to view. Many of these answers take hours to complete and require a high degree of technical expertise.
