People want to know if their personality traits are the problem. After a bad fight, alone in the car or staring at the ceiling at 2 a.m., the question surfaces: Is something about who I am making this worse?
It’s a reasonable question. But Gottman’s forty-plus years of research answer it in a way most people don’t expect. The data doesn’t sort couples by personality type. It sorts them by behavior — by what they do in the critical moments when connection is on the line. And behavior, unlike temperament, can be learned.
What Are Some Personality Traits?
The standard model in psychology organizes personality around five dimensions:
- openness,
- conscientiousness,
- extraversion,
- agreeableness, and
- neuroticism.
These are real and measurable. But in Gottman’s research, they rarely appear as primary predictors. What predicts the fate of a relationship is not what kind of person you are. It’s other factors, like whether you turn toward your partner or away. Whether you can repair after a rupture. Whether you can manage conflict without letting the Four Horsemen — criticism, contempt, defensiveness, stonewalling — take up permanent residence.
That said, personality is not irrelevant. It shapes the speed and style of your default reactions. And some defaults are harder to override than others.
Flooding: Where Physiology Meets Personality
In Gottman’s lab, one of the most reliable predictors of relationship breakdown is flooding — the physiological state where heart rate exceeds 100 bpm, adrenaline surges, and the capacity for rational conversation shuts down. When you’re flooded, creative problem-solving disappears. You’re left with fight, freeze, or flee.
Some people flood faster than others. In eighty-five percent of heterosexual couples Gottman studied, the partner who stonewalled — withdrew completely — was the husband. Not because men care less, but because the male cardiovascular system is more reactive to interpersonal stress and slower to recover. This isn’t a personality trait in the clinical sense. It’s physiology. But it looks like a personality trait from the outside: cold, distant, checked out.
The person on the receiving end of stonewalling rarely understands what’s happening inside the stonewaller’s body. They see indifference. What’s actually occurring is overwhelm. Somebody trying to calm down inside.
Knowing this changes the conversation. The question isn’t “why are you so cold?” It’s “what do you need to come back down so we can talk?”
Trust: The Game Theory of Relationships
In his landmark work The Science of Trust, Gottman introduces something surprising: game theory. Borrowed from mathematics and economics, it describes how two people in a relationship make decisions that either maximize joint benefit or individual benefit.
In this book, Gottman calls these orientations “cooperation” and “defection“. Cooperation looks for outcomes where both partners gain. Defection — consciously or not — optimizes for themselves, even sometimes at the partner’s expense. This isn’t about selfishness in the ordinary sense. These orientations can also show up in how couples “turn toward”, “turn away” or “turn against” bids for emotional connection.
Some personality patterns can make defection more likely. People with strong narcissistic traits, for instance, may consistently prioritize their own emotional needs without registering their partner’s. This doesn’t mean they can’t love. It means their default wiring makes mutual trust — Gottman’s specific, measurable definition of trust — and emotional connection harder to build.
For Gottman, trust is not just a feeling. It’s also a metric. It’s the answer to a question each partner is constantly, unconsciously calculating: Can I trust you think about what´s best for me too, also when I am not in the same room as you? Are we on the same team? Every interaction is a data point.

Where Sensitivity Helps — and Where It Hurts
People with high sensitivity traits process emotional signals at a deeper level. In a healthy relationship, this can be a strength — they notice bids for connection that others miss. But in a relationship marked by contempt, sensitivity may become a liability. The eye-roll, the sarcasm, the dismissive sigh — these can register at full volume and linger longer.
Sensitivity doesn’t cause the Four Horsemen. But it can determine how deep the wound goes when they arrive.
Skills, Not Traits, Predict Outcomes
Here is the central finding, and it’s worth saying plainly: Gottman’s research focuses on skills and “Small Things Often”, not personality traits. The presence of the Four Horsemen predicts divorce with high accuracy. But couples who use repair attempts — even clumsy ones — to de-escalate conflict can maintain stable, happy marriages regardless of their personality profiles. Eighty-four percent of newlyweds who were high on all four horsemen but repaired effectively were in satisfying marriages six years later.
The repair doesn’t have to be elegant. A goofy smile. A hand on the knee. “Can we start over?” What matters is that it lands — and that the relationship has enough goodwill in its emotional bank account for the partner to receive it.
Personality shapes where you start. Skills determine where you end up. And skills can be practiced.
Your traits are what you walk in with. What you build with them is a choice.
