Quick Definition

Conflict styles are the habitual ways people respond during disagreements, such as competing, avoiding, accommodating, compromising, or collaborating. Each style is a learned pattern shaped by upbringing and past relationships, not a fixed trait. Knowing your default helps you understand how you and a partner clash, and where you can practise healthier responses together.

Why How You Fight Matters

The five conflict styles are the avoider, the accommodator, the competitor, the compromiser, and the collaborator, and most people rely on one of them by default. The way conflict is handled in a relationship is one of the strongest predictors of relationship health. Gottman's research found that it is not the presence of conflict but the way it unfolds that determines outcomes. Specifically, contempt (expressing disgust or superiority toward a partner) is the single strongest predictor of relationship dissolution across cultures. Contempt is one of the four horsemen catalogued by the Gottman Institute. Yet most people give little attention to how they fight, focusing instead on what they fight about.

Conflict style is the pattern that determines how disagreements unfold, what happens to the relationship afterward, and whether both people feel heard or dismissed. Thomas and Kilmann's conflict mode instrument, developed in the 1970s and widely used since, identifies five conflict styles along two axes: assertiveness (how much you pursue your own goals) and cooperativeness (how much you consider the other person's goals). No single style is universally healthy or unhealthy. But most people have a default style, and that default shapes a great deal of how their relationships handle difficulty.

The Avoider

The avoider withdraws from conflict or works to prevent it arising. This is high cooperativeness combined with low assertiveness. In practice, it looks like changing the subject, going quiet, finding reasons to leave the room, or agreeing on the surface while inwardly disagreeing. Avoidance is often driven by a learned belief that conflict is dangerous or futile, by fear of damaging the relationship, or by an avoidant attachment pattern where distance feels safer than engagement.

Short-term, avoidance reduces tension. Long-term, unaddressed issues accumulate. The avoider often feels resentful about unresolved grievances. The partner often feels they cannot reach the avoider and may escalate in an attempt to get a response.

The Accommodator

The accommodator yields readily to the other person's position, prioritising the relationship's harmony over their own needs. This is high cooperativeness and low assertiveness. It looks like agreeing quickly to end conflict, minimising your own concerns ("it's fine, don't worry"), or consistently deferring to a partner's preferences. Accommodation is not always a problem. In low-stakes situations it is often the most practical choice.

The difficulty arises when it becomes a default across all conflict, when the accommodator builds up unexpressed needs and resentments while appearing outwardly agreeable. Partners of chronic accommodators often report frustration at not knowing what the person actually wants or needs from the relationship.

The Competitor

The competitor pursues their own goals strongly and resists yielding, even when the relationship would benefit from flexibility. This is high assertiveness combined with low cooperativeness. It looks like arguing to win, dismissing the other person's perspective, raising the stakes to force a resolution, or returning to the same conflict repeatedly until the other person concedes. Competitor behaviour often escalates under high stress, and research summarised by the National Institutes of Health (PMC) describes how stress can spill over and shape the way partners handle conflict.

It can originate in anxious attachment, in families where conflict was a contest, or in environments where showing vulnerability had costs. When both partners use a competitor style, arguments escalate rapidly and tend not to resolve. When one partner is a competitor and the other an accommodator, one person consistently gets their way while the other's needs go unmet.

The Compromiser

The compromiser seeks a middle ground, with both parties giving something up to reach a resolution. This is moderate on both assertiveness and cooperativeness. Compromise is widely considered a healthy default, and in many situations it is. The limitation of chronic compromise is that each party's goal is only partially met. In long-running relationships, if compromise is the only tool available, neither person's needs are fully honoured over time.

Compromise works best for practical decisions where partial satisfaction is acceptable. It is less suited to conflicts about values, identity, or fundamental needs, where a middle ground may satisfy neither person.

The Collaborator

The collaborator seeks a resolution that fully addresses both people's needs, treating the conflict as a shared problem to solve rather than a contest. This is high assertiveness and high cooperativeness. It is the most effortful style and requires both people to stay regulated, be genuinely curious about the other person's experience, and trust that the relationship can hold the tension of disagreement.

Gottman's research suggests that couples who are able to collaborate in conflict have better relationship outcomes on almost every measure. EFT research by Sue Johnson similarly shows that when conflict is approached from a position of secure attachment rather than threat, the quality of the conversation changes significantly. Collaboration is not always possible in every moment of conflict. But the capacity to eventually move toward it is one of the most valuable things a couple can develop.
