John and Julie Gottman are experts in researching what makes marriages last. They can determine whether or not a couple will stay married in just 15 minutes, with over 85% accuracy. Having researched over 3000 couples of various ages and sexuality over 32 years, they have studied various couples and have found what makes or breaks a relationship (Gottman, Making Marriage Work, 2006). They followed some couples for 20 years. Those who stayed married were called “masters” while those who got divorced or stayed together but were miserable were called the “disasters.” After following couples for fourteen years they were able to determine if and when a couple would get divorced (Gottman, audibles, 2006).
