What Is the Recipe for a Happy Marriage?

Over the years, psychologists have conducted dozens of studies to identify which variables are generally associated with happier marriages (Karney and Bradbury, 1995). These variables are good statistical predictors of marital satisfaction. For example, according to the studies, better-educated couples and higher-earning couples are generally happier than their less educated, less wealthy counterparts. Not always, of course, but more often than not.

Does this mean you can make your marriage more satisfying by going back to school or finding a better-paying job? Probably not. Marital satisfaction is affected by many factors, not one or two. And just because higher income predicts a happier marriage doesn’t necessarily mean that more money makes marriages happier. It’s possible that the causal arrow flies in the opposite direction, that happily married people are happier at work, which leads to greater success, frequent promotions, and higher pay.

With that caveat in mind, it’s worth repeating the main storyline: Research psychologists have identified numerous factors that are statistically associated with happier marriages. Individuals who are thinking about whether to enter into a long-term romantic relationship would be wise to consider what psychologists have learned.

In fact, couples thinking about tying the knot might want to consider some of the indicators of less happy, less satisfying relationships. For example, when one partner scores high on a measure of neuroticism (negative emotionality) or fear of separation, that doesn’t bode well. Other predictors of less happy marriages include financial problems, chronic illness, having many children, and parenting struggles (Karney and Bradbury, 1995). A lot of stress in one’s life is not a recipe for a happy marriage!

But here’s the thing. These findings may not apply to you. Almost all of these studies were conducted in Australia, Canada, the United States, or European countries. Would similar studies in South America, Asia, and Africa produce similar findings?

A Study of Marital Satisfaction in 65 Countries

To address the knowledge gap, German researcher Ina Grau and her team collected data from 15,205 participants in 65 countries on six continents (Grau and colleagues, 2025). All of the participants were legally married and born in the country where they lived. Their ages ranged from 18 to 92, with an average age of 44. Fifty-five percent of the participants were women. Because many of the individuals recruited for the study did not have easy access to a computer, all participants completed paper-and-pencil questionnaires.

The participants provided basic demographic data and completed questionnaires that measure the Big Five personality traits, attachment style, frequency of recent stressful experiences, aggressiveness, and problem-solving behaviors. To measure marital satisfaction, they completed an 11-item questionnaire that included questions such as “How satisfied are you with your relationship?” And, “How often do you wish you hadn’t gotten into this relationship?”

Grau and her team identified 20 variables that were statistically associated with marital satisfaction. Some of the factors—being better educated, being agreeable, having fewer children, and not being neurotic—were very weakly related to marital satisfaction. In actual marriages in many parts of the world, these variables probably have little or no impact on marital satisfaction. Other factors are more important.

A few of the variables measured in Grau’s study emerged as moderately good predictors of marital satisfaction. For example, participants who scored high on conscientiousness (being dutiful) or low on aggressiveness tended to report higher levels of marital satisfaction.

Grau and her team identified three factors that were strong predictors of marital dissatisfaction in almost all 65 countries. First, spouses who frequently ignored their partner were more likely to report an unhappy marriage. Second, spouses who frequently talked about separating from their partner were more likely to report an unhappy marriage. Third, spouses who were not securely attached (in a psychological sense) to their partner were more likely to report an unhappy marriage. These individuals said they were not emotionally close to their partner and were unsure if they could depend on their partner.

When Predicting Marital Satisfaction, Who Knows Best?

When reading about the factors associated with happy marriages, I’m often struck by how obvious the findings are. Of course, married people are happier when money is plentiful and when partners trust each other. Of course, married people are less happy when their partner neglects them.

Why It's Tough to Tell If You're Happily Married

If these are no brainers—and I think they are—then why do so many marriages start strong but eventually lose steam, ending in unhappiness or even divorce?

One explanation is our tendency to engage in emotional reasoning. When deciding whether to commit to a long-term relationship, couples sometimes give too much weight to their feelings and too little weight to the advice from friends and family.

When we’re young and caught up in an exciting, sexually charged romance, we often struggle to see what is fairly obvious to everyone else. Your boyfriend has a low-paying job and wants three kids? Your girlfriend likes to party, has a bad temper, and throws things when she’s angry? Anyone watching from the sideline knows this doesn’t bode well.

Most cultures around the world have proverbs that warn us about the dangers of emotional reasoning, especially when it comes to tying the knot. Love is blind. Measure twice and cut once. Fools rush in where angels fear to tread. Look before you leap.

My advice? Listen to your culture.
