Counter-anchor before you respond

When they open extreme, don’t negotiate from their number — reset with your own.

Why it works

Once an anchor is on the table it contaminates your judgment automatically, even when you know it’s manipulative. The defense isn’t willpower; it’s replacing the reference point — declining to counter from their figure and putting a well-justified anchor of your own beside it so the midpoint resets.

How to do it

1. Explicitly reject an extreme anchor rather than counter-offering off it.
2. Re-anchor with your own justified number to create a new reference point.
3. Return to objective criteria so the talk centers on standards, not their opening figure.

Evidence

Anchoring’s persistence even when people are warned is well documented; re-anchoring and considering counter-evidence are among the few partially effective debiasing strategies in research. Mussweiler, Strack, and Pfeiffer (2000) showed that deliberately considering the opposite compensates for the selective accessibility that drives the anchor, giving the reset a tested mechanism.

Debiasing is only partial — even informed, motivated people remain somewhat influenced. Re-anchoring reduces, not eliminates, the pull.

Common mistake

Making a "reasonable" counter that’s still measured from their extreme anchor, which cedes most of the range to them.
