Most weak essays were lost in week one. The topic was too big to argue, or too obvious to bother. Win here and the next month looks after itself.
“Korean cinema.” “Artificial intelligence.” “The housing market.” These are doors, not destinations. You can walk through one for the rest of your life and never make a single argument.
An essay needs a claim someone could reasonably disagree with. Getting there is the work of this chapter.
After every draft claim, ask it out loud. If your honest answer is “I'm not sure”, you have a topic, not yet a thesis. Keep narrowing.
Four moves take any subject down to something arguable. Each move makes the topic smaller and the claim sharper. Skip them and you draft for a week before noticing there was nothing to defend.
One worked example: a student starts with the convenience store on every Korean corner and ends with something a reader could argue against.
Convenience stores in Korea.
The 편의점 as everyday urban infrastructure.
Why does a Korean convenience store offer services a bank branch no longer will?
The 편의점 became a de facto public-service counter because deregulation let it absorb functions the state and the banks quietly retreated from.
“Smartphones are popular among Korean students.”
“So what?” · Everyone knows. Nothing to argue.“Near-universal smartphone ownership has made the 10 p.m. hagwon curfew unenforceable, pushing study online where no curfew reaches.”
“So what?” · Now there's a mechanism to defend.The second version names a cause and a consequence. That is the difference between a fact and a thesis, the reader can picture being wrong.
Say your topic out loud, then hit it with “so what?”
Too broad and there's no claim. Too narrow and there's nothing at stake. The target is one arguable mechanism you can defend in 1,500 words.
Take “social media in Korea.” Watch the same subject move from un-writable to writable to trivial.
A book, not an essay. No single claim can hold it. The reader can't tell what you'll argue.
Why open chat became Korea's de facto town square. One mechanism, arguable, defensible in 1,500 words.
A single data point, not an argument. There's nothing general left to defend.
Aim for the middle column: small enough to argue fully, big enough that the answer isn't already obvious.
Put the topic in the centre. Branch out everything you already know, sources, dates, people, counter-positions. The branch you can't stop writing on is the one you have an argument about.
Two short exercises. The first squeezes a topic down; the second pitches it in two sentences and proves it survives “so what?”
Pick a wide subject from your major. Run it through all four moves until the claim could bite back.
Read your partner only the Claim. Can they think of someone who'd disagree? If not, narrow once more.
Pitch the essay in exactly two sentences. Then run each draft “so what?” against the bar below.
Name the topic. What is this essay about?
State the claim, and signal why the reader should care.
Read sentence two aloud. Did anyone in the room want to push back? Good, that's the sign it's arguable.
Chapter 03, pages 15 to 17, including the worked “five topics, squeezed” page and Exercises 3.1 to 3.3.
