How to Write a Paper Introduction Reviewers Won't Skim

1. The 4-Move Structure

A strong introduction does four things in order: establishes the territory, identifies the

gap, states what you did, and previews the contributions. This maps closely to Swales' CARS

model that linguists derived from analyzing thousands of published papers — it is not a style

preference, it is what accepted papers actually do.

Draft each move as a single paragraph first. Most introductions are between four and six

paragraphs and one page. If you cannot say which paragraph does which move, your reviewer

will not be able to either.

2. Open With the Problem, Not the History

The most common weak opening is a slow historical wind-up: "Since the dawn of deep learning,

researchers have..." Reviewers have read that sentence a thousand times and it tells them

nothing. Open instead with the concrete problem and why it is currently unsolved.

Compare "Machine translation has a long history" with "Machine translation systems still

drop named entities in low-resource languages, and the standard fix — back-translation —

makes it worse." The second sentence does real work: it names a specific failure and hints

that the obvious remedy is inadequate. That is what earns the reviewer's attention.

3. The Gap Sentence Is the Most Important Sentence

Every introduction has one sentence that justifies the paper's existence. It usually starts

with "However," or "Yet," and it states precisely what prior work cannot do. If a reviewer

can read your gap sentence and still ask "so what?", the paper is in trouble regardless of

how good the experiments are.

Make the gap specific and falsifiable. "Existing methods are limited" is not a gap — it is

filler. "Existing methods require labeled data for every target domain, which is unavailable

for the 80% of languages with no annotated corpus" is a gap a reviewer can verify and care

about. Tie the gap directly to the contribution that closes it.

4. State Your Contributions as a List

After the gap, tell the reviewer exactly what you did with an explicit, bulleted contribution

list. This is the paragraph the area chair copies into the meta-review, so write it as if it

will be quoted out of context. Each bullet should be a claim you can point to a section to

support.

Avoid vague contributions like "we propose a novel framework." Reviewers discount the word

"novel." Instead: "We introduce X, the first method that does Y without Z." Lead each bullet

with the verb — introduce, prove, show, release — and attach a number wherever you can.

5. Length, Pacing, and the Roadmap Paragraph

For a conference paper, the introduction is roughly one page or about 10% of the body. Two

pages of introduction signals that you are padding or have not found your point. If your

territory section runs longer than your contribution section, rebalance — reviewers already

know the field.

The old "The remainder of this paper is organized as follows" roadmap paragraph is optional

and increasingly cut in top venues, because the section structure is visible in the table of

contents. Keep a roadmap only if your paper has an unusual structure a reader genuinely needs

warning about. Otherwise spend those sentences sharpening the gap.

6. Write It Last, Revise It First

Write the introduction after the experiments are done. You cannot honestly state your

contributions until you know which results survived. Many strong authors draft a one-paragraph

"intro skeleton" early to keep the paper focused, then rewrite it fully at the end once the

real story is clear.

During revision, the introduction is the first thing to fix, because it sets the frame every

reviewer reads the rest of the paper through. Read it aloud. If a co-author who has not seen

the work can state your contribution after reading only the introduction, it works.
