“A major insight into human behavior from pre-internet era studies of communication is the tendency of people not to speak up about policy issues in public—or among their family, friends, and work colleagues—when they believe their own point of view is not widely shared. This tendency is called the “spiral of silence.” Some social media creators and supporters have hoped that social media platforms like Facebook and Twitter might produce different enough discussion venues that those with minority views might feel freer to express their opinions, thus broadening public discourse and adding new perspectives to everyday discussion of political issues. We set out to study this by conducting a survey of 1,801 adults. It focused on one important public issue: Edward Snowden’s 2013 revelations of widespread government surveillance of Americans’ phone and email records. We selected this issue because other surveys by the Pew Research Center at the time we were fielding this poll showed that Americans were divided over whether the NSA contractor’s leaks about surveillance were justified and whether the surveillance policy itself was a good or bad idea. For instance, Pew Research found in one survey that 44% say the release of classified information harms the public interest while 49% said it serves the public interest.”
