An anonymous reader quotes a report from Vox: The art of suppressing dissent has been perfected over the years by authoritarian governments. For most of human history, the solution was simple: force. Punish people severely enough when they step out of line and you deter potential protesters. But in the age of the internet and "fake news," there are easier ways to tame dissent. A new study by Gary King of Harvard University, Jennifer Pan of Stanford University, and Margaret Roberts of the University of California San Diego suggests that China is the leading innovator on this front. Their paper, titled "How the Chinese Government Fabricates Social Media Posts for Strategic Distraction, Not Engaged Argument," shows how Beijing, with the help of a massive army of government-backed internet commentators, floods the web in China with pro-regime propaganda. What's different about China's approach is the content of the propaganda. The government doesn't refute critics or defend policies; instead, it overwhelms the population with positive news (what the researchers call "cheerleading" content) in order to eclipse bad news and divert attention away from actual problems. This has allowed the Chinese government to manipulate citizens without appearing to do so. It permits just enough criticism to maintain the illusion of dissent and only acts overtly when fears of mass protest or collective action arise.
