Can a Formula Predict Marriage Success?

Can a Formula Predict Marriage Success?

There are a lot of factors that we can probably agree contribute to marital happinessócommunication, stress, quality time, and intimacy, just to name a fewóbut is there such a thing as a formula that can predict the success of your marriage?

Yes, according to a series of studies done in the 1970s. And it’s a simple formula at that:

frequency of lovemaking minus frequency of quarrels

Work out the number for the past week or month. Is it a positive number? You’re in the clear. Negative? You may be heading for trouble. The formula came from a few studiesóone, looking at married couples at the University of Missouri-Kansas City, found that almost all self-described happy couples had sex more often than they argued, while all the self-described unhappy couples argued more than they had sex. A small study of 26 couples in 1974 had similar resultsóall 23 self-described happy couples had sex more, and all 3 self-described unhappy couples argued more.

Of course, we don’t recommend making any rash relationship decisions based off your score. John Howard and Robyn Dawes, the researchers behind the 1974 study, make a good point when discussing their findings in “Linear Prediction of Marital Happiness”:

“If a previously positive difference shifted to a negative score, the couple would at least be forewarned, and might seek the cause (and cure) of their problems.”

And if you’re thinking of solving your arguments by just having more sex, think again. Howard and Dawes do admit that correlation does not imply causationóand even if it did, there’s the whole chicken-or-egg argument to consider, too: Do you fight more because you have less sex or do you have less sex because you’re fighting more? Howard and Dawes caution, “It does not, for example, follow that we can increase marital happiness of people who argue a lot by encouraging them to have intercourse more often–but it would be an interesting technique to try.”

The most informative part of the article was the disclaimer paragraph at the end. Without it the article would seem misguided at best. Thanks.

There are way more variables involved in a good lasting relationship to consider. I believe it is several "formula's", that make it last, one of them being conflict resolution. Practicing selflessness is another, thinking of the other person & what his or her needs are & what simple tui GS one can do to make that person feel special & cherished & loved & appreciated. If those variables are met, than the sex will follow, if not, then it might be sex, but not intimacy & lovemaking.

Lots of sex and no disagreement? Marry an inflatable doll!

I agree, the formula should be:
mutual respect +(communication x2) -( infidelity x2) +common commitment = divided by 0.

There isn't likely any formula to relationship since it's communication and respect the trick
