It is quarter past nine in the evening. The general counsel arrived at eight that morning. She has eaten twice from the same buffet. She has just come off a ninety-minute call to a chief executive in another time zone who was asleep when it started. The mediator is now in the doorway with a number.
There is no time to model it. No time to call the board. No time to sleep on it. There is a flight at seven and a mediator who has run out of day. She says yes.
Everyone in the room believes a good outcome has been reached, and they may well be right. But nobody could say the decision was made in the conditions people need if they are to decide well.
My last two columns looked at this from the mediator's side of the table. I argued that the single day has become a definition rather than a format, and that we have never built the design skills that complex disputes now require. Both arguments were about us: our craft, our training, our fees. This column changes seats. The question is not what the single day costs mediators. It is what it costs the people who have to make the decision.
We Keep Half of the Promise
Every serious statement of mediation ethics rests on self-determination. The decision belongs to the parties. The mediator helps them reach it and does not make it for them.
We take that seriously in the ways that are easy to check. Is participation voluntary? Is the process confidential? Is anything being imposed from outside? What we have not taken as seriously is the state the party is in when she decides.
A party who is free to say no, and confidential in saying it, but who is tired, short of information, and out of time when she says yes, has been given the form of self-determination and very little of the substance. We have protected her right to decide. We have paid almost no attention to whether she is in a position to decide well.
That difference shows up six months later, when the number has to be explained to a board that was not in the room, or to a client asking why the case was not worth another week.
What a Long Day Does to Judgment
None of this is new or difficult. It is ordinary decision science, and it applies to general counsel and chief executives in the same way it applies to everyone else.
Herbert Simon showed that people working under constraint do not look for the best option. They satisfice. They take the first one that clears an acceptable bar. Kahneman and Tversky showed that the same number produces different answers from the same person on the same facts, depending on whether it is put as a gain or as a loss. And the research on decision fatigue is consistent: our capacity for careful judgement falls away over a long and demanding day. Later on, we reach for the cheapest rule of thumb, and for the framing of whoever spoke last.
The single day model does not simply live with these effects. It creates them, and then it puts the most important moment of the day at the point where they are strongest.
The evening deadline is not a neutral fact about diaries. It is choice architecture in the sense Thaler and Sunstein gave the term: a designed environment that shapes what people choose, whether or not anyone meant it to. Nobody sets out to extract a decision from a tired principal against an artificial clock. But that is what a quarter past nine ultimatum does. Calling it a deadline rather than a design has let us avoid asking whether it is a design we would have chosen or allowed the parties to choose.
There is a second cost, and it shows up later. A decision made under manufactured pressure is not owned in the way a decision made with time and information is owned. Parties who felt pushed rather than persuaded tend to start rewriting the deal in their own account of it almost as soon as they have signed, even if the words never change. Performance slips. Arguments about what was agreed come back. The settlement has settled the case without settling the relationship or the decision behind it.
Self-determination is not only a right at the moment of signature. It is a good indicator of whether the signature will hold.
Designing for the Decision
If the single day is a design that damages decisions, the answer is not to have no design. It is to have a better one, built on purpose, and aimed at the party's judgement rather than the momentum of the room. Four things matter most in a complex international mediation. None of them requires giving up urgency. They require choosing urgency rather than inheriting it.
The international element makes this harder to ignore. A general counsel deciding at nine in the evening in London is deciding at midnight or later somewhere else, and the person she would normally ring is asleep. Approval works differently in different places. Sometimes one signature is enough. Sometimes it needs a board that has not met since the mediation was booked. Documents arrive in a working language that is not everyone's first, and concepts that do not translate cleanly get decided on faster than they can be explained. None of that is unusual in international work. It is the normal condition of it. A format built for a two-party domestic claim, where the decision-maker is in the room and the number needs no translation, is being asked to carry more than it was built for. The parties absorb the difference.
The first thing is to get the information out before you ask for the number. Parties cannot price a risk they have not yet been allowed to understand. A staged exchange of information, before anyone is asked for a figure, closes a gap that otherwise gets papered over with a discount for uncertainty on one side and false confidence on the other. A party who has read the quantum model, the technical report, or the relevant correspondence before the joint session is deciding on what she knows. A party seeing it for the first time at the table is deciding on the shock of it.
The second is to design around real authority. I said last month that I would come back to this, and I will keep it short here. The person who can say yes needs enough notice to think. She should not be telephoned at midnight for a view on a term sheet she has never seen. Working with the authority that actually exists, and with the cycle on which it meets, is not a courtesy to the other side. It is what makes the decision the decision of the person accountable for it, rather than something relayed by someone improvising on her behalf.
The third is to sequence the decisions, not just the information behind them. A complex dispute contains a great many decisions dressed up as one. Procedure, valuation method, the treatment of a disputed head of loss, what happens to the relationship afterwards: all of that sits behind the figure that gets reported as the outcome. A designed process takes the smaller questions first, in order, so that the parties reach the large decision having already made several good ones together. A single day rolls the lot into one undifferentiated request for a yes, put to people who have nothing earlier to calibrate against.
The fourth is to build in reversibility. An interim agreement, a framework signed subject to conditions, a standstill with a review date: each of these turns one irreversible choice into a series of smaller ones that can be corrected. Asking a party to agree to a framework this week, to be reviewed in three, asks for something people are far better at giving than a final number under a clock. The framework may still fail. But it fails in a way that produces information rather than regret, and it can be redesigned rather than fought over.
A Fair Objection
The obvious answer to all of this is that time pressure is not always the enemy. Sometimes it is the only thing that produces a decision at all. Some parties will use an extra week to dig in rather than to think, and a deadline that concentrates minds is doing real work.
That is right, and it is not an argument against design. It is an argument for treating pace as something the mediator chooses, based on what is actually known about how a particular party decides, rather than something inherited from a diary that closes at nine. The single day does not save pressure for the cases that need it. It gives every case the same dose of pressure, whether it needs it or not. Whether it is beneficial or not.
Whose Decision It Is
My earlier columns argued that the format has outgrown its usefulness, and that we have not built the skills to replace it. This one is about why that matters beyond our own professional pride.
Process design is not something mediators do for their own benefit. It is not about our craft, our fees, or our reputations. We owe it to the parties and people who have to live with what they decide within that process. We tell them at the outset that the decision is theirs. That has to mean more than the right to say no.
A mediator who asks only whether the parties settled has answered the easy question. The harder question, and the one self-determination actually puts to us, is whether they were given the conditions to decide well. Running a good day gets people to quarter past nine. Only design asks what quarter past nine is doing to their judgement, and whether it needed to.
