The Five Thomas–Kilmann Conflict Styles, Explained
PsyCove Editorial · 11 min read · Updated 2026-10-12
- The five styles come from two dimensions: assertiveness and cooperativeness.
- Competing wins speed and loses goodwill; collaborating builds solutions and costs time.
- Avoiding is not cowardice — it is sometimes the correct move, especially when emotions are hot.
- Research shows flexibility matters more than any single style; over-use of avoiding predicts worse outcomes.
- In teams, relationship conflict consistently damages performance; task conflict can help in moderation.
The two dimensions
Every conflict-handling behavior balances two concerns: getting what you want, and keeping the relationship working. Assertiveness is the degree to which you pursue your own outcomes — stating needs, holding positions, pushing for decisions. Cooperativeness is the degree to which you pursue the other person's outcomes — listening, adapting, yielding. Plot those two dimensions on a grid and you get five regions, one for each style. The model's value is that it turns 'I'm bad at conflict' into a specific, observable question: which corner of the grid do you default to, and which corners do you avoid?
- Competing — high assertiveness, low cooperativeness: 'my way.' Fast decisions, clear stakes, damaged goodwill if overused.
- Collaborating — high on both: 'our best solution.' Integrates both concerns; expensive in time, best for important issues.
- Compromising — moderate on both: 'split it.' Practical for equal-power deadlocks; can leave both parties half-satisfied.
- Avoiding — low on both: 'not now.' Buys time and lowers heat; when it becomes permanent, issues fester.
- Accommodating — low assertiveness, high cooperativeness: 'your way.' Preserves harmony and teaches people your needs are optional.
Where the model came from
The framework grew out of the 1960s managerial-grid research of Robert Blake and Jane Mouton, who mapped leadership styles on concern for production versus concern for people. Kenneth Thomas adapted that two-dimensional logic to interpersonal conflict, and in 1974 Thomas and Ralph Kilmann published the Thomas–Kilmann Conflict Mode Instrument, which measures how much you use each of the five styles. The instrument became the standard in organizational training, and the model spread from management into negotiation, couples therapy, and mediation. A parallel academic tradition followed: Michael Rahim developed a competing measure in 1983, and decades of studies used both to connect conflict styles to outcomes.
One nuance worth keeping: the five styles describe behavioral intentions, not fixed personality. Kilmann and Thomas themselves noted that people shift styles by context — a manager who collaborates with a peer may compete with a vendor and avoid with a boss. A quiz score describes your recent average, not your destiny, which is exactly what makes the model useful: styles are habits, and habits are editable.
When each style fits
The situation selects the style. The question is never 'which style is best' but 'which style fits this conflict, at this cost, with this person.' Four situational variables do most of the work:
- Importance: how much is actually at stake, and whether the decision is reversible.
- Relationship: how much this relationship matters once the issue is settled.
- Time: how much of it you have before the decision has to be made.
- Power: how much each side holds, and whether either can impose an outcome.
- Competing fits emergencies and principle stands — when speed matters more than consensus, or when a core value is at stake.
- Collaborating fits complex, high-stakes issues where both concerns genuinely matter and the relationship must survive the outcome — merger terms, parenting decisions, career trade-offs.
- Compromising fits equal-power deadlocks with time pressure — splitting a difference is better than losing a quarter to a fight.
- Avoiding fits hot emotions and trivial issues — when the meeting would happen angry, or when the issue will resolve itself.
- Accommodating fits when you are wrong, when harmony matters more than the outcome, or when the issue matters far more to them than to you.
The failure modes are as informative as the fits.
- Chronic competing buys compliance and breeds resentment.
- Chronic collaborating exhausts everyone and can become a way of avoiding decisions.
- Chronic compromising guarantees that nobody is ever fully satisfied.
- Chronic avoiding guarantees that small issues become large ones.
- Chronic accommodating builds silent ledgers of grievance that eventually detonate.
Most people have one default style and one panic style — the one that appears when the stakes rise — and knowing both is more diagnostic than knowing the average.
What research says about styles and outcomes
The clearest research findings are not about which style wins — they are about flexibility and context. Studies consistently find that people who can move across styles depending on the situation achieve better outcomes than people locked into one. The worst-documented pattern is rigid avoidance: across studies in organizations and couples, habitual avoidance predicts unresolved problems, lower satisfaction, and worse performance, because the conflict does not disappear, it just relocates. Collaborating and compromising show the most consistently positive associations with satisfaction, especially in close relationships where the issue will recur. Competing shows mixed results: effective in emergencies and negotiations where your interests genuinely oppose theirs, corrosive when it becomes a default in cooperative relationships.
The team-level literature adds an important distinction. Carsten De Dreu and Laurie Weingart's meta-analysis separated task conflict — disagreement about the work — from relationship conflict — personal friction. Relationship conflict consistently damaged team performance and member satisfaction; moderate task conflict sometimes improved it, especially on non-routine tasks, by surfacing information. The practical translation: it is not conflict itself that hurts but whether the disagreement stays about the problem. The collaborating style is the machinery for keeping it there; the competing style is the fastest way to turn a task conflict into a relationship one.
- Flexibility across styles predicts better outcomes than strength in any single style.
- Habitual avoidance is the most reliably negative pattern across relationship and organizational studies.
- Relationship conflict hurts teams; moderate task conflict can help on non-routine work.
- Competing works in emergencies and true negotiations; it corrodes cooperative relationships when defaulted to.
- Accommodation helps short-term harmony but predicts resentment when it is the only move.
Choosing deliberately
The model becomes practical as a pre-conflict decision. Before a hard conversation, run four questions: what is actually at stake, how much does this relationship matter to me, how much time do I have, and what happens if I simply wait? The answers usually select the style before you open your mouth. The second discipline is mid-conflict monitoring: when you notice yourself escalating, the question is not 'am I winning' but 'is this still a task conflict, or has it become a relationship conflict?' The moment it turns personal, the only correct move is to de-escalate — avoid for an hour, accommodate on the small point, or shift to collaborating on the underlying concern.
The third discipline is post-conflict repair, which is where most styles fail quietly. A competing exchange that ends in a decision still leaves a relationship bill unpaid; the invoice gets settled later, with interest, or not at all. Naming it — 'that got heated, I care about the outcome and about you' — is the accommodating move applied after the fact, and it is what keeps a necessary competing conflict from becoming a relationship one.
Conflict styles across situations and cultures
The same person runs different styles in different rooms. Power is the strongest situational variable: people compete upward and accommodate downward, or the reverse, depending on what their environment has rewarded. Relationship length is the second — new colleagues get avoidance and accommodation, long-term partners get the styles that have actually worked before. And stakes sort the rest: trivial issues get avoiding or accommodating because the alternative costs more than the issue, meaningful issues get collaborating or competing. A single style score is therefore an average across contexts you have actually been in, not a fixed setting — which is why the score often changes after a new job or a new relationship.
Culture shapes conflict norms in ways that matter for cross-cultural teams. Direct, explicit disagreement is the professional norm in some contexts and a rudeness in others; the accommodating style may be a relationship-preserving virtue in one culture and a credibility cost in another. Research on gender and conflict style finds differences that are real but small — smaller than the cultural and situational effects — and the practical implication is that expectations about how conflict 'should' look are learned locally, and traveling teams should negotiate those expectations explicitly rather than assume them.
The most useful output of the model for most people is a style inventory under pressure. Ask which style appears when you are frightened, which when you are angry, and which when you are embarrassed — the three are often different, and the frightened one is usually the least developed. Flexibility training targets the missing cell, not the average score.
Repair after conflict
The style you use during conflict determines the bill; the repair determines whether it gets paid. A competing exchange that ends in a correct decision still leaves a relationship invoice, and unpaid invoices accrue interest at a rate that surprises people — the same argument three months later is usually about the four unpaid ones. The repair sequence that the clinical literature supports is unglamorous: acknowledge the specific behavior without the but ('I raised my voice and cut you off'), name the impact rather than the intent ('that landed as contempt, whatever I meant'), and state the concrete change ('when I feel myself escalating, I'm going to ask for a ten-minute pause and take it').
The accommodating repair — applied after a competing conflict — is the most underused move in the model. It costs nothing during the fight and everything afterward: 'you were right about the timeline, and I was defensive because I was embarrassed.' The research on conflict in close relationships consistently finds that the ratio of repair to rupture predicts relationship health better than the frequency of conflict itself. Couples who fight well and repair reliably outperform couples who rarely fight, because the repair is what makes the next conflict safe to have.
Frequently asked questions
What are the five conflict styles?
Competing, collaborating, compromising, avoiding, and accommodating — defined by two dimensions, assertiveness (pursuing your own concerns) and cooperativeness (pursuing the other person's). Each style fits different situations, and most people over-use one or two.
Which conflict style is best?
None universally. Research consistently finds that flexibility — matching the style to the situation — predicts better outcomes than any single preferred style. Collaborating and compromising show the most positive associations in close relationships; competing fits emergencies and true negotiations; rigid avoidance is the most reliably negative pattern.
Is avoiding conflict a weakness?
Not inherently — avoidance is correct for hot emotions, trivial issues, and situations where waiting resolves the problem. It becomes a problem when it is habitual, because unresolved conflicts do not disappear; they accumulate and resurface larger.
What is the difference between compromising and collaborating?
Compromising splits the difference — both sides give something up. Collaborating searches for a solution that addresses both concerns fully, which takes more time and creativity but avoids half-satisfied parties. Compromising fits time-boxed deadlocks; collaborating fits important recurring issues.
Can conflict styles change?
Yes. The styles describe behavioral habits, not fixed traits, and people already shift across them by context — a different style appears with a boss, a peer, and a partner. Training and deliberate practice can widen the range, especially for the styles you avoid under pressure.
