Offering to mediate a dispute between departments gives a peer manager control of the process, from meeting structure to draft language, which they use to tilt the outcome toward one side.
An example
Maintenance and network planning at a regional airline had been fighting for months over how many spare aircraft to hold back each morning. The head of revenue management, a peer of both department heads, offered to broker a settlement, and the chief operating officer was relieved to let him. He ran four sessions. His summaries called planning's position pragmatic and maintenance's a maximal ask, and the draft compromise he wrote started from planning's number. Every version of the settlement came from his laptop, and his update to the chief operating officer described the head of maintenance as the holdout. When she refused the third draft, the chief operating officer told her she was being inflexible. She learned later that revenue management's bonus that year was tied to how many hours the fleet flew.
Why it works
Holding the pen and the summaries lets the broker work on all four sides of the choice. The favored side's case looks better because the neutral voice repeats it and calls it realistic, and its path gets easier because the broker drafts the memos and picks the formats. The other side's case looks worse once it is cast as the extreme from which compromise must be extracted, and refusing a fair-sounding compromise costs more, because it reads as stubbornness to whoever the broker reports to. It works when the parties take the neutrality at face value, the broker controls procedure, and the dispute is complex enough that the reasonable middle is unclear.
The thinking behind it
Daniel Kahneman Daniel Kahneman's Judgment under Uncertainty: Heuristics and Biases (1974), written with Amos Tversky, describes anchoring: people estimate by adjusting from a starting value, and the adjustment is usually too small. A broker whose draft compromise starts from one side's number sets the anchor for everything that follows. Drafting your own language and tabling it early defends against this because it puts a second anchor on the table.
Thomas C. Schelling Thomas Schelling's The Strategy of Conflict (1960) describes focal points, solutions that stand out to both sides and anchor tacit bargains. A mediator who writes every draft decides which midpoint looks natural and fair, and refusing it then looks unreasonable. Insisting that both parties approve summaries word for word takes back some control over which point becomes focal.
Erving Goffman Erving Goffman's Frame Analysis (1974) defines a fabrication as the deliberate management of activity so that others form a false belief about what is going on. A false arbitrator fabricates neutrality: the parties believe they are in a mediation when they are negotiating with a third interested party. Asking the mediator to disclose their stake before the first session tests the frame at the start.
Warning signs
The supposedly neutral broker drafts every settlement text and decides which version of events goes up the chain. Summaries describe one side's position in approving words and the other's as extreme. The proposed midpoint keeps landing nearer one side. The broker's own interest in the outcome, through a bonus, a budget, or an alliance, has never been discussed.
How to defend yourself
Before accepting a mediator, ask what stake they have in the outcome, and get the answer in front of both parties.
- Draft your own language and table it, so the broker's draft is never the only text.
- Insist that any summary of the sessions be approved word for word by both parties before it circulates.
- Send your own account of the dispute upward, factually and on your own schedule.
- Where a neutral with formal authority is available, such as a shared boss or an operating committee, take the dispute there.
Treat the proposed middle as one more argument, and test it against the facts.
How a leader shuts it down
Assign mediation of internal disputes to someone with formal authority and no stake, and ask any volunteer broker to disclose their interests first. Require summaries of mediated sessions to be approved by both parties before they reach you. When one side is described as the holdout, hear that side directly before you agree.
