Back in 2002, psychologists studying how couples argued found four different behaviors that correlated strongly with future divorce. In fact, in a small sample of 80 couples, the combination of those behaviors could be used to predict who would divorce over the next 14 years with 93% accuracy. The good news: While these behaviors are all things that people probably do sometimes, it’s the frequency of behaviors that matters … and, better yet, they’re all things that you can change. At PsySociety, Melanie Tannenbaum uses the amazingly spot-on example of Kim Kardashian and Kris Humphries to illustrate how unhealthy arguments can lead to relationship collapse.
