Instagram, Meme Seeding, and the Truth about Facebook Manipulation, Pt. 1

  • Jonathan Albright is the Research Director at the Tow Center for Digital Journalism. Previously an assistant professor of media analytics in the school of communication at Elon University, Dr. Albright’s work focuses on the analysis of socially-mediated news events, misinformation/propaganda, and trending topics, applying a mixed-methods, investigative data-driven storytelling approach.
  • The last couple of weeks have brought us the first new major revelations about the reach and scope of the IRA media influence campaign. Yet the most important development about the ongoing Facebook investigation isn’t the tenfold increase in the company’s updated estimate of the organic reach of “ads” on its platform.

    While the estimate increasing the reach of IRA content from 10 million people to 126 million people is surely a leap, after last week’s testimony, the real question we should be asking is: how did we suddenly arrive at 150 million?

    The answer is Instagram.

Reading The Group Polarization Phenomenon working on the PolarizationGame. Some thoughts:

  • There needs a way for each player to state their support/oppose state on a slider before the debate begins. We could even color code the threads using that information, though maybe only when viewing after the debate is complete.
  • What about teams?

The Emergence of a Fovea while Learning to Attend

  • Everything is about how we deal as individuals and groups with imperfect information. Which is why a attention-based economy is crazy

Identifying Dogmatism in Social Media: Signals and Models

  • We explore linguistic and behavioral features of dogmatism in social media and construct statistical models that can identify dogmatic comments. Our model is based on a corpus of Reddit posts, collected across a diverse set of conversational topics and annotated via paid crowdsourcing. We operationalize key aspects of dogmatism described by existing psychology theories (such as over-confidence), finding they have predictive power. We also find evidence for new signals of dogmatism, such as the tendency of dogmatic posts to refrain from signaling cognitive processes. When we use our predictive model to analyze millions of other Reddit posts, we find evidence that suggests dogmatism is a deeper personality trait, present for dogmatic users across many different domains, and that users who engage on dogmatic comments tend to show increases in dogmatic posts themselves.
