Essay practice: judging by the worst case
A bridge is judged by the flood it was not built for.
Write an essay of 1000 to 1200 words. 125 marks.
This topic is a metaphor. In 2020 to 2026, 13% of essay topics took this form. Here are three real ones to practise on next:
| Topic | Paper |
|---|---|
| Ships do not sink because of water around them, ships sink because of water that gets into them. | UPSC Mains 2020, Essay, Section A |
| Muddy water is best cleared by leaving it alone. | UPSC Mains 2025, Essay, Section B |
| When two elephants fight, it is the grass that gets trampled. | UPSC Mains 2026, Essay, Section A |
The bridge and the flood stand for something else. The sentence makes a claim about how we judge things. Your first job is to say that claim in plain words.
Translate it first
Rewrite the sentence with no image in it.
We judge things by how they behave in conditions they were never designed for.
Now you can argue with it. Is that fair? Is it useful? Can we avoid it?
Use the image in the opening and in the conclusion. Argue in plain words in between.
Before you write: four questions
- What is the claim, without the image? Write it in one plain sentence.
- What does the claim assume about judgement? It assumes we judge by failure. Is that true? Is it right?
- Name one thing that should be judged by normal conditions. Say why the worst case is the wrong test for it.
- What is your position? Say how far you agree and where the claim stops being true.
Check your thinking
Which of these is the best plain translation of the topic?
Show answer & explanation
Answer: (C) We end up judging things by how they cope with what they were never designed for.
The answer is (C). It removes the image and keeps the claim, which is about how we judge things. (A) and (D) take the image literally and lead to an essay on infrastructure or climate. (B) writes about the bridge itself. Check a translation by asking whether it still makes a claim about how we judge things. Only (C) does.
You have translated the topic. How much should the bridge appear in the essay?
Show answer & explanation
Answer: (B) Once in the opening and once in the conclusion, and nowhere else.
The answer is (B). The image gives you an opening, and returning to it in the conclusion gives the essay a clear shape. (A) and (D) keep every paragraph inside the picture, so the essay never states its argument in plain words. (C) wastes a good opening, and the examiner may think you did not see that the topic was a metaphor.
A suggested structure
| Paragraph | What it does |
|---|---|
| 1 | Open on one real structure and the event it was not designed for |
| 2 | Translate, and state the thesis: judging by the worst case is unfair, and we cannot avoid it |
| 3 | Why it is unfair: nothing can be designed for every case, and extra strength costs money |
| 4 | Why we do it anyway: a design's limits only show when it fails |
| 5 | A case where judging by the failure was right |
| 6 | The objection. Where judging by the worst case does harm |
| 7 | What those cases share: the worst case was rare and the cost of preparing was certain |
| 8 | So the useful test weighs how likely the worst case is against what preparing costs |
| 9 | Close by returning to the structure from paragraph 1 |
Now plan it yourself
✍️ Your turn
Write your plan, not the essay. In 150 words or fewer: give your plain translation of the topic in one sentence, then your thesis, then one line per paragraph saying what it argues. Mark the paragraph that handles the objection.
Compare with a model plan
Open this only after you have written your own.
A model plan for this topic
Translation. We judge things by how they behave in conditions they were never designed for.
Thesis. That judgement is unfair, and we cannot do without it, because a design's limits only show when it fails. What we can do is state openly what preparing for the rare case would cost.
- A named structure, and the event that went beyond what it was built for. One concrete paragraph, with no argument yet.
- Translate. State the thesis.
- Why the judgement is unfair: every design has a limit, chosen on purpose. A higher limit costs money now for a benefit that may never come.
- Why we judge that way anyway: until a design fails, nobody can see what was given up. Failure shows it.
- A case where that judgement was right, because a warning had been ignored.
- The objection. Where judging by the worst case does harm: money moves to rare events, and everyday services go short.
- What those cases share: a rare risk and a certain cost. The judgement punished a reasonable choice.
- So the fair test weighs how likely the flood was against what preparing would have cost. The failure is refusing to state that trade.
- Return to the structure in paragraph 1. Somebody chose its limit. Ask whether they said so at the time.
Why this plan works.
- It drops the image after paragraph 2 and returns to it only in paragraph 9.
- Paragraphs 3 and 4 argue the two halves of the thesis in turn. Paragraph 3 says why the judgement is unfair, and paragraph 4 says why we make it anyway.
- Paragraph 8 gives a test someone could apply to a real decision.
Then write the essay
Write it to your plan and submit it for evaluation. You will get a comment on each of the five criteria and one change to make in your next essay.
