Write contingent contracts when forecasts disagree
If you and the other side have different predictions, let the outcome decide who was right.
Key takeaways
- What it is: If you and the other side have different predictions, let the outcome decide who was right.
- Why it works: Negotiators often deadlock because each side genuinely believes the world will unfold in their favor. A contingent contract converts that disagreement into a bet: if my prediction is right, the terms tilt my way; if yours is right, they tilt yours. It resolves the impasse without either side having to abandon their belief, and aligns incentives with performance.
- Evidence: Plausible mechanism, limited direct outcome data.
- Avoid: Using a contingent contract to obscure rather than resolve a disagreement — drafting vague triggers to get a signature, which guarantees a dispute when the contingency fires.
Why it works
Negotiators often deadlock because each side genuinely believes the world will unfold in their favor. A contingent contract converts that disagreement into a bet: if my prediction is right, the terms tilt my way; if yours is right, they tilt yours. It resolves the impasse without either side having to abandon their belief, and aligns incentives with performance.
How to do it
- 1Identify where the disagreement is factual rather than values-based (“we think sales will hit X; you think Y”).
- 2Propose a deal where the terms adjust based on the actual outcome.
- 3Make the contingency measurable, time-bound, and agreed by a neutral arbiter if needed.
- 4Write the trigger conditions and consequences explicitly before signing.
What the evidence says
MechanisticContingent contracts are a well-documented integrative tool in the negotiation literature. Bazerman and Gillespie’s work in Harvard Business Review outlines their use and common conditions under which they add joint value.
Honest caveat: Contingent contracts require that the outcome be observable and verifiable by both parties; they fail when the contingency is ambiguous or one party can game the measure.

Common mistake
Using a contingent contract to obscure rather than resolve a disagreement — drafting vague triggers to get a signature, which guarantees a dispute when the contingency fires.
