Move the goalposts
"Move the goalposts" is an idiomatic expression often used to describe a deceptive or unfair tactic where the criteria or conditions for achieving success are changed or shifted during the course of an activity or negotiation. Originally stemming from sports, particularly football, where the goalposts demarcate the area where scoring occurs, this phrase metaphorically implies altering the terms of an agreement or challenge to make it more difficult for someone to achieve their objective. It implies a sense of unfairness or manipulation, as the initial parameters or expectations are altered after someone has already committed to or invested in the endeavor.
Metaphorically, "move the goalposts" represents a breach of trust or a lack of integrity, as it undermines the perceived fairness of the situation. For example, in a business negotiation, one party might accuse the other of moving the goalposts if they suddenly introduce new conditions or demands after initial terms have been agreed upon. Similarly, in personal relationships, changing expectations or requirements midway through a project or commitment can lead to feelings of frustration or betrayal. Overall, this expression highlights the importance of clear communication and maintaining consistent standards to ensure fairness and trustworthiness in any endeavor.
