Definition

What is it?

The 'Moving the Goalposts' fallacy happens when someone changes the rules or conditions for success after a task has already started or been completed. It's like shifting the target you need to hit after you've already thrown the ball, making it impossible to win fairly.

Simple Example

Quick Example

Imagine your parents tell you that if you score 80% in your Maths exam, you can get a new video game. You study hard, score 82%, and excitedly tell them. But then they say, 'Oh, we meant 90% and also 85% in Science.' This is moving the goalposts.

Worked Example

Step-by-Step

Scenario: You want to convince your friend, Rohan, that your favourite cricket team, the 'Mumbai Lions,' is the best.

Step 1: You say, 'Mumbai Lions are the best because they won the championship last year.'
---Step 2: Rohan replies, 'But they lost 3 matches this season.'
---Step 3: You then change your argument: 'Okay, but they have the most popular captain and the highest fan following!' (Here, you changed the 'goalpost' from winning matches to popularity and fan following because your original argument was challenged).
---Step 4: Rohan points out, 'But we were talking about being the 'best team' based on winning, not popularity.'
---Answer: You moved the goalposts by shifting the criteria for 'best team' from winning performance to popularity after Rohan countered your original point.

Why It Matters

Understanding this fallacy helps you think clearly and spot unfair arguments in daily life. It's crucial in fields like law, where fair rules are key, and in research, to ensure experiments follow consistent standards. Journalists also use it to report facts accurately without changing the story.

Common Mistakes

MISTAKE: Confusing moving goalposts with simply changing your mind or learning new information. | CORRECTION: Moving goalposts is about changing conditions unfairly *after* a task or argument has begun, specifically to avoid admitting defeat or to make success impossible.

MISTAKE: Thinking any disagreement is moving the goalposts. | CORRECTION: It's only moving goalposts if the *criteria for success or agreement* are altered mid-discussion, not just disagreeing on a point or introducing new, relevant information.

MISTAKE: Not realizing *who* is moving the goalposts. | CORRECTION: The person moving the goalposts is usually the one making the original claim or setting the original condition, then shifting it when challenged.

Practice Questions

Try It Yourself

QUESTION: Your sister promised to share her chocolates if you finished your homework. You finish it, but then she says, 'I'll share only if you also clean my room.' Is this moving the goalposts? | ANSWER: Yes, because she changed the condition for sharing chocolates after you met the original one.

QUESTION: Your school announced that students who score above 90% in the annual exam will get a special prize. After the results, they say, 'Actually, only the top 3 students will get the prize.' Is this a Moving the Goalposts fallacy? | ANSWER: Yes, because the condition for the prize changed from a specific percentage to a limited number of students after the exams were over.

QUESTION: Your friend says, 'I can run 100 meters in 15 seconds.' You time him, and he runs it in 17 seconds. Then he says, 'Oh, I meant I can run 100 meters in 15 seconds *if I wear my special running shoes*.' Is this moving the goalposts? Explain why or why not. | ANSWER: Yes, it is moving the goalposts. He changed the condition for his claim (wearing special shoes) *after* the attempt failed to meet the original, unqualified claim.

MCQ

Quick Quiz

Which of these is an example of 'Moving the Goalposts'?

A shopkeeper lowers the price of a shirt because it's not selling well.

Your coach says you need to run 5km in 30 minutes, and after you do, he says, 'Now you need to do it in 28 minutes to qualify.'

You decide to study a new topic because your old one was too easy.

A chef changes a recipe because he found a new ingredient.

Real World Connection

In the Real World

You see this fallacy sometimes in online debates or even in product reviews. For example, a company might promise a software update to fix a bug, but after the update, they might say, 'We meant the *next* update will fix it,' pushing the solution further away. Or in politics, a leader might promise to achieve something by a certain date, and when that date passes, they change the conditions for success.
