Dr. Gottman is an expert on what makes marriages fail or succeed.

A new article on Business Insider explains his research in a nutshell.

Excerpt: (emphasis mine)

Gottman wanted to know more about how the masters created that culture of love and intimacy, and how the disasters squashed it. In a follow-up study in 1990, he designed a lab on the University of Washington campus to look like a beautiful bed and breakfast retreat.

He invited 130 newlywed couples to spend the day at this retreat and watched them as they did what couples normally do on vacation: cook, clean, listen to music, eat, chat, and hang out. And Gottman made a critical discovery in this study — one that gets at the heart of why some relationships thrive while others languish.

Throughout the day, partners would make requests for connection, what Gottman calls “bids.” For example, say that the husband is a bird enthusiast and notices a goldfinch fly across the yard. He might say to his wife, “Look at that beautiful bird outside!” He’s not just commenting on the bird here: he’s requesting a response from his wife — a sign of interest or support — hoping they’ll connect, however momentarily, over the bird.

The wife now has a choice. She can respond by either “turning toward” or “turning away” from her husband, as Gottman puts it. Though the bird-bid might seem minor and silly, it can actually reveal a lot about the health of the relationship. The husband thought the bird was important enough to bring it up in conversation and the question is whether his wife recognizes and respects that.

People who turned toward their partners in the study responded by engaging the bidder, showing interest and support in the bid. Those who didn’t — those who turned away — would not respond or respond minimally and continue doing whatever they were doing, like watching TV or reading the paper. Sometimes they would respond with overt hostility, saying something like, “Stop interrupting me, I’m reading.”

These bidding interactions had profound effects on marital well-being. Couples who had divorced after a six-year follow up had “turn-toward bids” 33 percent of the time. Only three in ten of their bids for emotional connection were met with intimacy. The couples who were still together after six years had “turn-toward bids” 87 percent of the time. Nine times out of ten, they were meeting their partner’s emotional needs.

By observing these types of interactions, Gottman can predict with up to 94 percent certainty whether couples — straight or gay, rich or poor, childless or not — will be broken up, together and unhappy, or together and happy several years later. Much of it comes down to the spirit couples bring to the relationship. Do they bring kindness and generosity; or contempt, criticism, and hostility?

“There’s a habit of mind that the masters have,” Gottman explained in an interview, “which is this: they are scanning social environment for things they can appreciate and say thank you for. They are building this culture of respect and appreciation very purposefully. Disasters are scanning the social environment for partners’ mistakes.”

“It’s not just scanning environment,” chimed in Julie Gottman. “It’s scanning the partner for what the partner is doing right or scanning him for what he’s doing wrong and criticizing versus respecting him and expressing appreciation.”

Contempt, they have found, is the number one factor that tears couples apart. People who are focused on criticizing their partners miss a whopping 50 percent of positive things their partners are doing and they see negativity when it’s not there.

People who give their partner the cold shoulder — deliberately ignoring the partner or responding minimally — damage the relationship by making their partner feel worthless and invisible, as if they’re not there, not valued. And people who treat their partners with contempt and criticize them not only kill the love in the relationship, but they also kill their partner’s ability to fight off viruses and cancers. Being mean is the death knell of relationships.

Kindness, on the other hand, glues couples together. Research independent from theirs has shown that kindness (along with emotional stability) is the most important predictor of satisfaction and stability in a marriage. Kindness makes each partner feel cared for, understood, and validated—feel loved. “My bounty is as boundless as the sea,” says Shakespeare’s Juliet. “My love as deep; the more I give to thee, / The more I have, for both are infinite.” That’s how kindness works too: there’s a great deal of evidence showing the more someone receives or witnesses kindness, the more they will be kind themselves, which leads to upward spirals of love and generosity in a relationship.

There are two ways to think about kindness. You can think about it as a fixed trait: either you have it or you don’t. Or you could think of kindness as a muscle. In some people, that muscle is naturally stronger than in others, but it can grow stronger in everyone with exercise. Masters tend to think about kindness as a muscle. They know that they have to exercise it to keep it in shape. They know, in other words, that a good relationship requires sustained hard work.

“If your partner expresses a need,” explained Julie Gottman, “and you are tired, stressed, or distracted, then the generous spirit comes in when a partner makes a bid, and you still turn toward your partner.”

In that moment, the easy response may be to turn away from your partner and focus on your iPad or your book or the television, to mumble “Uh huh” and move on with your life, but neglecting small moments of emotional connection will slowly wear away at your relationship. Neglect creates distance between partners and breeds resentment in the one who is being ignored.

The hardest time to practice kindness is, of course, during a fight—but this is also the most important time to be kind. Letting contempt and aggression spiral out of control during a conflict can inflict irrevocable damage on a relationship.

“Kindness doesn’t mean that we don’t express our anger,” Julie Gottman explained, “but the kindness informs how we choose to express the anger. You can throw spears at your partner. Or you can explain why you’re hurt and angry, and that’s the kinder path.”

The whole article is worth reading. It’s very practical, I think. It’s always good to read things like this and then analyze how you are acting. That’s why it’s important to read articles like this and read books on marriage – to always hold your actions accountable to people who understand what makes a relationship work. It’s worth it to put in the time to understand these things, because relationships matter.

My Dad always used to have this habit of going after people when he was in the right, but it’s a relationship destroyer to just let loose even if you are right. To build a relationship, you have to be doing constructive things with that other person even when they have done you wrong. You can’t always be making withdrawals, there have to be deposits, too. Otherwise the relationship dies.

The Five Love Languages is a useful book for knowing how to love someone else. Even in the middle of a fight, it’s good to speak encouraging words, good to give gifts, good to touch, good to serve, good to spend time together. It takes work to be intentional about doing things that convey love to that other person – even when there are conflicts in the background.
