Recognize reactive devaluation in yourself and your counterpart
An offer you would accept from a neutral party may feel unacceptable simply because your adversary made it — know this bias by name.
Key takeaways
- What it is: An offer you would accept from a neutral party may feel unacceptable simply because your adversary made it — know this bias by name.
- Why it works: Reactive devaluation is an attribution-based bias: when a counterpart proposes something, the proposal is assumed to serve their interests, which triggers suspicion about its value to you. This is automatic — people rate identical proposals lower when they believe the adversary generated them. It kills integrative deals: a good joint-gain proposal from the counterpart is discounted before it is evaluated on its merits.
- Evidence: Backed by observational / correlational evidence.
- Avoid: Rejecting a proposal from your counterpart that you would have been pleased to have proposed yourself — and then spending sessions trying to reach a worse version of the same deal.
Why it works
Reactive devaluation is an attribution-based bias: when a counterpart proposes something, the proposal is assumed to serve their interests, which triggers suspicion about its value to you. This is automatic — people rate identical proposals lower when they believe the adversary generated them. It kills integrative deals: a good joint-gain proposal from the counterpart is discounted before it is evaluated on its merits.
How to do it
- 1When evaluating a counterpart’s proposal, explicitly ask: would I accept this exact proposal if a neutral party had made it?
- 2Separate evaluation from attribution: what does this proposal actually give me, independent of who suggested it?
- 3Name the bias openly in high-trust negotiations: "I want to make sure I’m not discounting this just because you brought it up."
What the evidence says
ObservationalReactive devaluation has been demonstrated experimentally: participants systematically rated a proposal lower when attributed to their adversary than when attributed to a neutral mediator, even when the content was identical.
Honest caveat: Reactive devaluation is strongest in adversarial or politically charged contexts and weaker in cooperative ones. The bias is not universal.

Common mistake
Rejecting a proposal from your counterpart that you would have been pleased to have proposed yourself — and then spending sessions trying to reach a worse version of the same deal.
IX Coach helps you evaluate proposals on their actual content by asking you to articulate what the proposal gives you before asking how you feel about who made it.
