Are there tell-tell signs that a couple's marriage will end in divorce? Renowned researcher Dr. John Gottman thinks so.

For 40 years, the University of Washington psychology professor and his team at the Gottman Institute have studied thousands of couples' interactions to determine the key predictors of divorce.

The predictors -- which Gottman calls "the four horsemen of the apocalypse" -- are more commonplace than you'd think: criticism (sharing a complaint while putting the blame on your partner), contempt (negative thoughts about your partner coming from a position of superiority), defensiveness (self-protecting either in the form of victimizing yourself or righteous indignation) and stonewalling (emotionally withdrawing from your partner.)

Check out the infographic below for more on what the Gottman Institute has gleaned from four decades of research.
