The First Number Sets the Range

Anchoring is the most-replicated finding in negotiation behavioural science: whoever names the first number drags the eventual outcome toward it, even when both parties know the anchor is partly arbitrary. The gravitational pull is mechanical — the human brain literally adjusts insufficiently from whatever starting point is offered. A €3.2M opening anchored against a €2.4M target tends to land you closer to €2.8M; a €2.5M opening against the same target tends to land you closer to €2.3M. Same target, different starting points, half a million euros of distance.

The implication is uncomfortable for negotiators trained to wait and listen: going second without a defensible counter-anchor is the most common single source of money left on the table. You inherit the counterpart's frame, and every move you make from there is measured against their number, not yours.

Three rules sit beneath the effect:

Anchors only work if they're defensible. A credible aggressive anchor needs at least one reason behind it — a market benchmark, a peer project, a constraint the counterpart can verify. Naked aggression collapses under one calibrated question ("Walk me through how you got to €3.2M").

Anchors leak through ranges, not just point numbers. "We're typically at €2.8M to €3.2M for this spec" anchors at €3M (the midpoint), and also gives you cover to land at the bottom of the range without it feeling like a concession.

The counterpart's first number is data, not destiny. Their opening anchor tells you where they *hope* the negotiation lands, not where it *will* land. Treat it as a signal, not a starting point you must split.

One nuance that separates skilled anchoring from amateur anchoring: specificity is itself an anchor. A price of €2,847,500 lands differently than €2.8M, even though they're materially the same number. The precise figure signals that the price was calculated, not pulled from a range; the round number signals it was constructed for negotiation. Use round numbers when you want to invite negotiation; use precise numbers when you want to convey that the figure already reflects all the math. Most negotiators default to round and leave signal on the table without realising it.

When to Anchor First — And When to Wait

The choice of whether to open or let the counterpart open isn't a personality preference; it's a function of information asymmetry.

Anchor first when:

You have clear information about the deal's value (yours and theirs) and a defensible aggressive number.
The counterpart is likely to open absurdly low — pre-empting them costs less than re-anchoring later.
You're the seller of a premium or differentiated offering and the counterpart's reference points are commodity benchmarks. Their anchor will be tied to the wrong basket.
The conversation has stalled and someone needs to put a stake in the ground.

Let them anchor first when:

You have genuinely poor information about market rates or their walkaway, and their anchor will tell you more than yours would.
You're the buyer of a category where sellers routinely over-anchor and then concede dramatically.
The relationship is early and they need to feel they're driving the substantive frame.

The asymmetric case worth knowing: when the counterpart opens *extremely* aggressively — well outside any defensible range — they have given you a gift. Their anchor is so weak that re-anchoring on top of it is almost cost-free, and you've also learned that they're either inexperienced or testing whether you'll flinch. Both are useful intel.

The re-anchor move is the single most underused response in negotiation. When their opening number is unacceptable, do not engage with it. Do not counter with a slightly better number. Replace their anchor entirely: "We're actually looking at this in the €2.8M to €3.2M range — let's start there." Said calmly, without justification, it forces them to either defend their original number (hard) or accept your range as the new playing field (easy).

There's a difference between going second strategically and going second by accident. Going second strategically means you've decided their anchor will give you useful information, and you have a re-anchor ready. Going second by accident means you walked in without a plan, they named a number, and now you're trying to figure out what to do against gravity. The fix is to prepare your three anchors even when you intend to let them open — the worst case then becomes pulling out your prepared opening rather than improvising one under pressure. Anchoring discipline is a planning artifact, not a real-time skill.

Re-Anchor vs. Concession-Counter

Mid-market manufacturing deal. The counterpart opens roughly 35% below the seller's defensible range. Watch how the trained response replaces their anchor entirely instead of negotiating against it.

Setup

Industrial automation vendor, second meeting with a Polish automotive parts manufacturer.

Counterpart

We've benchmarked this and we're at €1.4M. That's where we are.

Untrained you

We can't do €1.4M — we're at €2.1M but I could probably move to €1.9M to get this done.

Concedes 10% before they've conceded anything — and anchors against their number.

Trained you

€1.4M is significantly below what this scope costs to build at our quality. We're at €2.1M for the full package. Walk me through your €1.4M number — is that for the same spec, or a stripped one?

Refuses their anchor, names own, forces them to defend or unbundle.

Takeaway

The counter-offer rewards their opening. The re-anchor erases it.

Five Rules for Opening Moves

Plan three anchors, not one. Aggressive (top of defensible range), realistic (target), fallback (walkaway). Walk in knowing which you'll lead with based on the first three minutes of context. Improvising the opening is how you under-shoot.

Always name a reason with the anchor. "Our number is €2.8M because…" — even a thin reason makes the anchor 50% harder to dismiss. Numbers without reasons are pure opinion and collapse under one question.

Use ranges to anchor high while leaving room. "Typically €2.8M to €3.2M for this spec" puts the midpoint at €3M and lets you eventually settle at €2.8M while feeling like a concession to them.

If you go second, re-anchor in your first sentence. Don't counter their opening. Make your full opening as if theirs didn't happen. "Let me share where we are: €2.8M for the full scope." This denies the gravitational pull.

Plan the Ackerman ladder before you open. Once anchored, you need the choreography of your concessions: typically 65% / 85% / 95% / 100% of target, with decreasing increments signalling you're running out of room. Anchoring without a ladder is half a strategy.

The Three-Anchor Drill

Before your next significant negotiation, sit down with paper and write three numbers:

Aggressive anchor — the highest number you can defend with a real reason. Not a fantasy number — the highest credible one. Write the one-sentence reason next to it.

Realistic target — where you actually want to land. This is the number you'll fight to defend; everything else is in service of it.

Walkaway — the number below which no deal is better than this deal. Be honest. This is the floor of your willingness to negotiate.

Now write the opening line you'll deliver: which anchor you'll name, the reason behind it, and the structural device (range vs. point, with or without bundled items). Practise saying it aloud three times until it sounds natural rather than rehearsed.

Then plan the Ackerman concession ladder from aggressive anchor to target: four numbers, decreasing increments (20%, 10%, 5%, 5%). Each later level should have a small non-monetary sweetener you can throw in on the third or fourth move — a maintenance year, a training day, expedited shipping.

The output: one page with seven numbers, one opening line, and four concession moves. That page is the difference between negotiating from a script and negotiating from a hope.

Techniques in this module

Ackerman Bargaining

Chris Voss

A scripted four-step concession plan: open at 65% of target, then move to 85%, 95%, and 100% with diminishing increments.

Bend Their Reality

Chris Voss

Use loss aversion, anchoring, and framing to make your offer feel inevitable rather than negotiable.

Anchoring

General

Set the first number — it disproportionately influences the entire range of the negotiation.

The Flinch

General

A visible negative reaction to an offer — silence, a wince, a sigh — that signals the offer is unacceptable without saying it.

Bracketing

General

Place your target between your opening offer and theirs, so a "split the difference" lands on your number.

Assessment

Take the assessment as a live spar. Score at least 6.0 on the target dimension to pass.
