Your Reddit posts could predict a breakup over 3 months before it happens

Reddit posts from over 6,800 users showed that their language patterns changed up to three months before a breakup, a new study has revealed.

(CNN)One person was dumped before finals week after a four-year relationship. Another broke off a relationship with their boyfriend because he had fallen in love with someone else.

These two brutal breakups seem to have nothing in common, and yet both users' Reddit posts hinted at a breakup months in advance.
An analysis of over a million Reddit posts has shown that a user's language patterns change up to three months before a breakup, according to a study published Monday in the journal Proceedings of the National Academy of Sciences.
    Researchers took posts from over 6,800 users who had posted in the subreddit r/BreakUps and ran them through a text processing program to analyze their linguistic patterns in the year before through the year after their breakups. (r/BreakUps is an online forum on the social news platform Reddit, where over 143,000 members post their breakup stories.)
      At the time of a user's breakup post, there was a spike in the average use of self-focused words like "I" and "me," which are personal pronouns, said lead study author Sarah Seraj, a doctoral student at the University of Texas at Austin.
        The increase in self-focused words were observable three months before the breakup and didn't return to normal language patterns -- measured by the poster's average patterns four to 12 months before the breakup -- until up to six months after the relationship ended.
        There was also a steep drop in a poster's analytical thinking, which is a standardized measurement of the formality of someone's writing, Seraj said. The drop, which indicates an increase in personal narratives and informal writing, happened because people were writing about deeply personal topics, she said.

          Nonbreakup posts showed similar patterns

          Researchers analyzed both a user's posts in r/BreakUps and their posts in other Reddit forums, called subreddits. Self-focused words increased and analytical thinking decreased around the time of the breakup, regardless of whether their posts were about their failed relationship, the researchers found.
          "The effects of the breakup are translating into other areas of their life, even when they're not directly talking about it," Seraj said.
          At the time of the breakup post, there was a spike in the user's cognitive processing words like "think" and "should," which are used when someone is trying to work through a problem, Seraj said.
          There was also a spike in a user's collective thinking -- noted by the use of the word "we" -- at the time of the breakup, but it dropped back to normal levels within a couple months.
          "They can't really separate their partner's identity from their own, so they use more 'we' words because they're talking about their shared life with their partner," Seraj said.

          Long-term posters take longer to return to normal

          Users who spent five or more days posting in r/BreakUps took much longer for their language patterns to return to normal compared to those who posted for fewer than five days. While short-term users' analytic thinking returned to normal two months after the breakup, it took long-term users six months, according to the study.
          The study didn't analyze why long-term users took longer, but Seraj hypothesized that their breakups could have been messy so they needed more support, or the user kept ruminating on the relationship, preventing them from moving on.
          For those still struggling six months after a breakup, Seraj recommended speaking to a therapist or seeking other professional help.
