Psychologist says maths can predict chances of divorce

A psychologist claims that a newly devised mathematical model can predict with 94% accuracy which couples will divorce - entirely on the basis of the first few minutes of a discussion about some disputed issue.  John Gottman, of the University of Washington, and two applied mathematicians analysed hundreds of videotaped conversations between couples in Professor Gottman's relationship research institute. They also analysed pulse rates and other physiological data to provide a "bitterness rating" for each conversation. 
 
The researchers were looking for what they called the "masters and disasters" of marriage. What mattered was not the dispute itself, but a couple's attitudes during the argument. "When the masters of marriage are talking about something important, they may be arguing, but they are also laughing and teasing and there are signs of affection because they have made emotional connections," Prof Gottman said. "But a lot of people don't know how to connect or how to build a sense of humour, and this means that a lot of fighting that couples engage in is a failure to make emotional connections.
"We wouldn't have known this without the mathematical model."
 
The researchers will take part in a symposium on love and marriage at the American Association for the Advancement of Science in Seattle tomorrow. On St Valentine's Day, they will produce the magic ratio of positive to negative interactions that is the mark of marital success. This ratio is 5 to 1: couples who keep their tempers and consider each other 80% of the time while arguing stand a chance of celebrating their golden wedding. Those who fall below this ratio might as well dial the lawyers, or at least the marriage guidance counsellors. The team say their model charts a "Dow Jones industrial average for marital conversation".
 
Prof Gottman has spent almost 30 years trying to discover what makes marriages work and fail. In 1999, he unveiled a systematic study of conversations between 124 couples who had been married less than nine months, and rated them for emotion, gesture and attitude. The "positive" codes were for affection, humour, joy, interest and validation. And then there were ratings for disgust, contempt, anger, fear, defensiveness, whining and sadness. At the end of three years, 17 couples had divorced.

  1. Analytic thing are so favorite of mine. I love to read this kind of post. You don't know how important for me this analytic topic. Thanks for share this. I will follow this blog. And waiting for your next post.

  2. This article is related to the German war and everyone understands that German was incredibly crazy to fight the other country. I need to examine the recorded setting of the German people about the fight and wars.

  3. When we look at the issues so these issues are not disputed at all and we need to read more about the issues to solve them but we are in hurry to make early decisions and these decisions are paid in future.

  4. That is the mental collaboration of both the persons in a marriage because you have to check it what other has done and how a work can be done in a more precised way.

  5. O wow this is so curious to know about the reality of this research. I can definitely go with this maths prediction and must go to https://www.summarizing.biz/best-summarizing-strategies/best-summarize-tool-online for details. So this excellent post.
