Competing (assertive, uncooperative)

Pursue your own position firmly when speed, principle, or stakes outweigh the relationship cost.

Why it works

Competing maximizes assertiveness and minimizes cooperation — you push for your outcome. It works when a decision must be made fast, when you’re right on a high-stakes safety or ethical matter, or when yielding would do real harm. Its cost is relational: overused, it makes others stop bringing concerns, so it’s a precision tool, not a default posture.

How to do it

1. Reserve it for genuine high-stakes, time-critical, or non-negotiable issues.
2. Be explicit that you’re overriding, and why, rather than steamrolling silently.
3. Repair afterward — name the relational cost and tend to it once the decision is made.

Evidence

The Thomas-Kilmann model is a widely used, decades-old framework with an established self-report instrument (the TKI). The five-mode typology is well known; outcome claims for each mode are situational and not from controlled trials, so this is mechanistic. (mechanistic)

The TKI is a self-report typology, not an outcome study; "which style wins" depends heavily on context.

Common mistake

Defaulting to competing on low-stakes issues, winning the argument while quietly losing the relationship and others’ willingness to be honest with you.
