The vise comes down to a single sentence, repeated calmly: "You'll have to do a good deal better than that." Without justifying or naming a figure, you hand the ball back to the other side and force them to improve their offer against themselves, often more than once. The silence that follows does all the work.

Indicative NEGOCOACH editorial rating, for teaching purposes. For “Relational risk”, a high value signals a cost to the relationship, not a quality.
The VISE in Brief
Origin & history
The vise ("the vise gambit") was codified by Roger Dawson, one of the most influential negotiation trainers in the United States, in Secrets of Power Negotiating (1987). Dawson uses it to illustrate a principle he hammers home: in a negotiation, whoever speaks last after an offer is often the one who wins. By boiling your reply down to a single unjustified sentence, you deny the other party any purchase for counter-argument and transfer the entire burden of proof onto them. The technique embodies the idea that verbal minimalism, coupled with silence, is a pressure weapon in its own right.
Definition and principle
A minimalist pressure tactic, the vise exploits the discomfort of the void: the party who has just made an offer, having no counter-proposal to respond to, fills the silence by conceding. Arguing nothing prevents the other side from counter-arguing and concentrates the whole burden of proof on them.
Concrete examples of application
Application by context
The same technique, across several negotiation settings
A buyer receives a quote and simply replies, "you'll have to do a good deal better than that," then falls silent. The seller, with no foothold to defend himself, comes back of his own accord with a discount.
Context 2 / 6
Labour negotiation
Faced with an initial management proposal, a union negotiator merely says, "that falls short, this needs a serious rethink," forcing the management to sweeten its offer.
Context 3 / 6
Crisis management
A mediator repeats, "this gesture isn't enough, you need to go further," without specifying, pushing the party to outbid itself in its conciliatory gestures.
Context 4 / 6
Political negotiation
A party leader meets a concession with "that is wholly inadequate given what is at stake," obliging the opposing camp to improve its position to avoid the talks collapsing.
Context 5 / 6
Real-estate negotiation
To a seller's counter-offer, the buyer lets slip, "you'll need to make a real effort on that price," leaving the seller to fill the silence with a fresh reduction.
Context 6 / 6
Family negotiation
In a negotiation between heirs, one replies to a proposal with "this division isn't even-handed, it needs revisiting," compelling the other to adjust without a single specific argument having been put forward.
Counter-techniques
Spot and neutralise this technique
Negotiation is also played on defence. Here is how to recognise this technique when it is used against you, and turn it around.
Detect
The signals that give it away
A string of easy "yeses"
Social proof ("everyone signs")
Commitment obtained step by step
Neutralise
The counters that defuse it
Spot the small-yes → big-yes mechanism
Refuse to commit in stages
Ask to settle everything in one block
Turn around
Turn it into an advantage
Demand a counterpart for each of your "yeses".
The trap to avoid
Accepting small commitments that lock you in.
Strengths and weaknesses
The vise is economical, hard to counter (you cannot refute a non-proposal) and shifts all the pressure onto the other side. Its limits: by never proposing anything, you risk deadlock or irritation; against a seasoned negotiator, the riposte ("what exactly are you proposing?") turns the vise back on you.
When to use this technique?
Useful when the other side has more room than you and the balance of power allows it. Best avoided if you need to demonstrate your good faith, or when facing someone who will in turn demand a costed counter-proposal.
Objectives of the technique
Obtain a concession without having to put forward a costed counter-proposal yourself
Get the other party to reveal their real room for manoeuvre and their reservation floor
Anchor the discussion on the idea that the first offer is inadequate, without fixating on a figure
Transfer the burden of effort and of the next move onto your counterpart
Preserve the relationship by staying vague and non-aggressive, while keeping up the pressure
Famous cases
Sales · The buyer who won't budge: An industrial buyer receives a supplier's quote of €84,000 for a batch of machines. Rather than proposing a counter-price (which would become the new high anchor), he simply replies: "You'll have to do better than that," then falls silent and waits. Uncomfortable in the silence, the salesperson ends up conceding a discount and throwing in an extended warranty of his own accord, without the buyer ever putting forward a figure. The vise did all the work: it was the seller who negotiated against himself.
Everyday life · The garage's price: A private individual receives a repair quote. Instead of contesting it line by line, he says calmly, "Honestly, you'd need to make an effort on that," then lets the silence settle. The mechanic, trying to fill the void, spontaneously offers to remove a labour item. Here the technique rests entirely on the brevity of the sentence and the refusal to pad it out.
Common mistakes
Filling the silence: adding a justification or a question after the fallback sentence destroys the whole effect, because it is the void that pushes the other side to concede
Putting a figure on the improvement you expect yourself ("give me 10%"), which turns the vise into a counter-offer and hands the other side an anchor
Using an aggressive or threatening tone: the vise must stay neutral and almost good-natured so as not to put backs up
Repeating the vise several times over on the same offer: beyond once, it loses its credibility and comes across as manipulative
Using the technique without a genuine alternative (BATNA): if the other side calls the bluff and doesn't budge, you are left with no way out
Limits and ethics
The vise brings no argument at all: that is in fact its very principle, it works precisely because it does not argue, does not name a figure and does not justify itself, leaving the other side to negotiate against themselves to fill the void. Saying that an offer is inadequate is perfectly legitimate, and doing so without piling on explanations avoids sterile debates. What is problematic is the repeated, one-sided use: endlessly parroting "you'll have to do a good deal better" without ever giving your own position is no longer negotiating, it is making the other side pay the price of your silence. Negotiation presupposes a minimum of reciprocity; the vise removes it. Its seriousness changes radically with the balance of power: between seasoned professionals it is a familiar duel and the device wears out fast. Faced with a counterpart in a position of dependence, a supplier who cannot afford to lose the account, a candidate who needs the job, silence is no longer a tactic, it is the exercise of power. Saying an offer is inadequate is a position; refusing indefinitely to give one is a power play dressed up as negotiation.
