How It WorksSEC 01
Anchoring is the tendency for an initial number to bias every judgment that follows it, even when that number is arbitrary or irrelevant (Tversky & Kahneman, 1974). In their classic demonstration, a spun wheel of fortune shifted people’s estimates of an unrelated statistic simply by showing them a high or low figure first. Once an anchor is in mind, we adjust away from it — but not far enough — so our final answer stays magnetically close to where we started.
Manipulators exploit this by controlling which number you see first. An inflated “original” price makes a discount feel like generosity; an extreme opening offer drags the negotiated midpoint toward the mover; pre-set “suggested” donation or tip amounts lift the entire range of what feels normal. Because the pull operates below awareness, simply knowing about anchoring offers little protection — the anchor still tugs even at people who can name the effect.
The defense is to establish your own reference point before theirs enters the picture. Influence that is honest survives you setting the price you’d independently pay; manipulation depends on their number arriving first and framing the whole conversation. When the only basis for a figure is that someone stated it confidently and early, that is the anchor showing itself.
Warning SignsSEC 02
- An arbitrary first number. A figure appears early — a "list price," an opening offer — with no clear basis, and quietly frames everything after.
- Inflated "original" price. A crossed-out high number makes the real price feel like a rescue rather than a cost.
- Extreme opening offer. A first bid far from reason, calibrated to drag the eventual midpoint toward the mover's favor.
- Suggested amounts pre-filled. Donation or tip screens where the default choices are set high to lift the whole range.
- Precision theater. An oddly specific number ($1,247) borrowing false authority to look researched.

How the Hook LandsSEC 04
Stage 01 · Plant
A number is introduced first — a sticker price, an opening demand, a suggested amount — before you've formed an independent estimate.
Stage 02 · Adjust
You reason outward from that anchor, and characteristically stop adjusting too soon, landing closer to it than the facts warrant.
Stage 03 · Settle
The final figure feels self-chosen and fair, when in truth it was tethered to a reference someone else set.
Counter-ProtocolSEC 05
Defense: Decide what it's worth before you look at their number — then treat their number as noise.
- Set your own anchor first. Form an independent estimate of fair value or your walk-away point before any figure is shown to you.
- Interrogate the reference. Ask what the "original" or opening number is actually based on; arbitrary anchors dissolve under a direct question.
- Re-anchor deliberately. In negotiation, respond with your own well-reasoned figure rather than adjusting from theirs.
- Compare to outside data. Check independent comparables — market rates, other quotes — so the seller's number isn't your only reference point.
