People are more willing to share a news article on Facebook than actually read it.
According to a new study by computer scientists at Columbia University and the French National Institute, 59 percent of links shared on social media have never actually been clicked: In other words, most people appear to retweet news without ever reading it. Worse, the study finds that these sort of blind peer-to-peer shares are really important in determining what news gets circulated and what just fades off the public radar. So your thoughtless retweets, and those of your friends, are actually shaping our shared political and cultural agendas. “People are more willing to share an article than read it,” study co-author Arnaud Legout said in a statement. “This is typical of modern information consumption. People form an opinion based on a summary, or a summary of summaries, without making the effort to go deeper.” [(Source)](https://www.washingtonpost.com/news/the-intersect/wp/2016/06/16/six-in-10-of-you-will-share-this-link-without-reading-it-according-to-a-new-and-depressing-study/)
