““With every post, tweet, or pin, users anticipate social validation. Rewards of the tribe keep users coming back, wanting more. Sites that leverage tribal rewards benefit from what psychologist Albert Bandura called “social learning theory.”[lxxvi] Bandura studied the power of modeling and ascribed special powers to our ability to learn from others. In particular, Bandura showed that people who observe someone being rewarded for a particular behavior are more likely to alter their own beliefs and subsequent actions. Notably, Bandura also showed that this technique works particularly well when people observe the behavior of people most like themselves, or those who are slightly more experienced (and, therefore, role models).[lxxvii] This is exactly the kind of targeted demographic and interest-level segmentation that social media companies such as Facebook and industry-specific sites such as Stack Overflow selectively apply.””
