Overview

Moving the goalposts, also called shifting the goalposts, is an idiom meaning that someone alters the criteria for success, acceptance, or victory after a process has already begun. The phrase draws on the image of changing a sports target mid-game so that a previously achievable score is no longer sufficient. In everyday use it describes tactics in arguments, negotiations, hiring, and decision-making intended to avoid conceding a point or to secure an advantage.

How it works and common examples

At its core the tactic replaces agreed standards with new demands once the original condition is met. Examples include:

A debater who requires one test of evidence, then rejects it and demands another when it appears;
An employer who asks a candidate to meet a listed qualification, then adds extra requirements after the candidate applies;
A negotiator who accepts terms, later insisting on further concessions;
Scientific claims that are insulated from refutation by constantly changing what would count as disproof.

Relation to logical fallacies and distinctions

Moving the goalposts is often treated as an informal fallacy because it prevents fair evaluation. It overlaps with special pleading and the "no true Scotsman" pattern but differs from bait-and-switch commerce in that it usually concerns standards rather than an initial promise. Whether intentional or accidental, it undermines rational discourse by rendering outcomes unfalsifiable or negotiations unstable.

Consequences and why it matters

When participants shift criteria, trust erodes, cooperation breaks down, and decisions lose credibility. In public debates and science, it can hide weak arguments; in workplaces and courts it can be unfair or even illegal if contractual obligations are altered without consent.

How to respond

Practical countermeasures include documenting agreed criteria, asking for reasons for changes, insisting on objective measures, proposing independent arbitration, and calmly pointing out the shifted standard. Calling attention to the change and requesting a return to the original terms often restores fairness.
