Are You Making These Dissertation Writing Mistakes?

After years of research and writing, many doctoral students submit dissertations that are held back not by the quality of the research but by avoidable writing mistakes. Here is exactly what committees look for in dissertation writing quality — and how to fix the most common writing errors before your draft reaches your committee.

You have done the research. You have read the literature. You have collected the data, built the argument, and written hundreds of pages. And then your committee sends your draft back — not because of the research but because of the writing.

This happens more often than most doctoral students expect. Writing quality is one of the leading reasons dissertation drafts are returned for revision. Committees expect doctoral-level academic writing — clear, precise, well-structured, and formally appropriate throughout. When the writing does not meet that standard the argument suffers regardless of how strong the underlying research is.

The writing mistakes that get dissertations returned are not random. They are predictable, recurring errors that appear in doctoral dissertations across every field and every institution. Understanding what they are — and knowing how to fix them — is one of the most valuable things a doctoral student can do before submitting a draft for committee review.

This comprehensive guide covers the most common dissertation writing mistakes doctoral students make, why they undermine the quality of the dissertation, and exactly how to fix them before your committee sees your work.

Why Writing Quality Matters in a Doctoral Dissertation

Before covering the specific mistakes it is worth understanding why writing quality is evaluated so seriously in doctoral dissertations.

A doctoral dissertation is not just a research report. It is a scholarly argument — a sustained, coherent, evidence-based claim about a significant question in your field. The quality of the writing is inseparable from the quality of the argument. An argument that is unclear, imprecise, or poorly structured is an argument that fails to communicate its own significance.

Writing quality also signals scholarly credibility. Committees evaluate not just what you argue but how you argue it. Imprecise language, weak sentence structure, and unclear transitions signal that the student has not yet developed the level of scholarly command expected at the doctoral level. Strong, precise, well-organized writing signals the opposite.

Finally writing quality affects accessibility. A dissertation that is difficult to read — because of dense passive constructions, vague terminology, or poorly organized paragraphs — is a dissertation that fails to communicate its contribution to the field. The best research in the world loses its impact if it cannot be read and understood clearly.

Mistake 1 — Overuse of Passive Voice

Passive voice is the single most pervasive writing problem in doctoral dissertations. It appears in virtually every draft reviewed by dissertation committees and it is one of the first things professional dissertation editors correct.

Passive voice occurs when the subject of the sentence receives the action rather than performing it.

Passive: The data were analyzed by the researcher. Active: The researcher analyzed the data.

Passive: It has been argued by scholars that... Active: Scholars have argued that...

Passive: Welfare policy was shaped by racial ideology. Active: Racial ideology shaped welfare policy.

Passive voice is not always wrong — there are legitimate reasons to use it in academic writing, particularly when the actor is unknown, unimportant, or deliberately unspecified. But chronic overuse of passive voice produces writing that is indirect, imprecise, and difficult to follow. Committees notice it immediately.

How to fix it:

Read your dissertation chapter by chapter specifically looking for passive constructions. Ask for every passive sentence: who is performing the action? If you can identify the actor make the sentence active. Reserve passive voice for situations where the actor is genuinely unknown or where the passive construction is rhetorically deliberate.

Mistake 2 — Wordiness and Redundancy

Doctoral students often equate length with scholarly rigor. The result is writing that is padded, repetitive, and bloated with unnecessary words, phrases, and sentences that add length without adding meaning.

Common forms of wordiness in dissertation writing:

Redundant phrases:

"past history" — history is always past
"future plans" — plans are always future
"completely finished" — finished means complete
"currently existing" — existing means current

Empty intensifiers:

"very important" — just say "important" or find a stronger word
"quite significant" — just say "significant"
"extremely crucial" — crucial already means extremely important

Wordy constructions:

"due to the fact that" — use "because"
"in order to" — use "to"
"at this point in time" — use "now"
"it is important to note that" — delete entirely and state the point directly
"as previously mentioned" — delete and restate if truly necessary

Circular sentences: Sentences that restate the same idea twice in different words — "The policy was ineffective and failed to achieve its goals" says the same thing twice.

How to fix it:

Edit for wordiness by asking of every sentence: does every word earn its place? Can I say this in fewer words without losing meaning? Cut every phrase that does not add information. Replace wordy constructions with direct ones. A tighter sentence is almost always a stronger sentence.

Mistake 3 — Vague and Imprecise Language

Academic writing at the doctoral level demands precision. Vague language — language that could mean multiple things or that does not specify exactly what is being claimed — undermines the credibility of your argument and frustrates your committee.

Common examples of vague language in dissertations:

"Many scholars have argued..." — which scholars? Cite them.
"Research shows that..." — what research? Cite it specifically.
"This is significant because..." — significant in what way? For whom? Why?
"There are various factors..." — what factors? Name them.
"Society has long recognized..." — which society? When? Who specifically?
"Things improved over time..." — what things? How much? Over what time period?

Every claim in your dissertation must be specific, attributed, and supported. Vague language signals that the student has not done the analytical work necessary to make a precise claim.

How to fix it:

Review your dissertation for any sentence containing the words "many," "some," "various," "things," "factors," "aspects," "society," "people," and similar vague terms. Replace each one with specific language — name the scholars, cite the research, identify the specific factors, and define the time period and context.

Mistake 4 — Weak Paragraph Structure

A dissertation paragraph should do one thing — develop one idea, argument, or piece of evidence — and do it completely. Weak paragraph structure is one of the most common writing problems committees flag because it signals unclear thinking about the argument.

Common paragraph structure mistakes:

Paragraphs without a clear topic sentence: Every paragraph should begin with a topic sentence that states the main idea of the paragraph clearly. A paragraph that begins with evidence or background before stating its main point is difficult to follow.

Paragraphs that do one but not all of three things: A strong academic paragraph typically does three things — it states the main idea (topic sentence), it develops and supports the idea with evidence and analysis, and it connects the idea back to the broader argument (concluding sentence). A paragraph that states an idea and presents evidence but never analyzes the evidence is incomplete.

Paragraphs that are too short: A one or two sentence paragraph in academic writing signals an underdeveloped idea. If you cannot write at least four to six sentences developing an idea the idea may not be strong enough to stand as its own paragraph — consider merging it with an adjacent paragraph.

Paragraphs that are too long: A paragraph that runs for a full page or more has almost certainly moved beyond one idea into two or three. Break long paragraphs at natural division points — when a new idea or piece of evidence is introduced.

How to fix it: Read every paragraph in your dissertation and ask: what is the main idea of this paragraph? Is it stated clearly in the first sentence? Is the idea fully developed with evidence and analysis? Does the concluding sentence connect back to the broader argument? If any answer is no revise the paragraph accordingly.

Mistake 5 — Unclear or Missing Transitions

Transitions are the connective tissue of a doctoral dissertation. They show the reader how ideas, paragraphs, and sections relate to each other and how the argument develops from one point to the next. Missing or weak transitions produce a dissertation that feels choppy, disjointed, and difficult to follow.

Common transition problems in dissertations:

No transition between paragraphs: Moving from one paragraph to the next without any connecting language forces the reader to figure out on their own how the two ideas relate. Strong transitions make the connection explicit.

No transition between sections: Moving from one section or subheading to the next without a transitional passage leaves the reader without orientation. Before each new section or heading a brief closing passage in the previous section should signal the transition.

No transition between chapters: At the end of each chapter a brief concluding passage should summarize what the chapter has established and preview what the next chapter will address. This chapter-level transitioning helps the reader follow the cumulative development of the argument.

Overuse of simple transitions: Relying on "however," "furthermore," "additionally," and "therefore" for every transition produces mechanical, repetitive writing. Strong transitions vary in form and are embedded naturally in the language of the sentences.

How to fix it:

Read your dissertation aloud — from the end of one paragraph to the beginning of the next — and listen for places where the connection between ideas is unclear. Write transitions that name the connection explicitly: "Building on this argument...", "This evidence challenges the assumption that...", "While Chapter 2 established the historical context, Chapter 3 turns to..."

Mistake 6 — Contractions and Informal Language

Contractions — don't, can't, it's, won't — have no place in doctoral dissertation writing. Neither do colloquialisms, informal phrases, or conversational language. Yet these appear in dissertation drafts with surprising frequency — often because the student has been working on the document for so long that the line between academic register and conversational writing has blurred.

Common informal language mistakes in dissertations:

Contractions: "don't" — use "do not" "can't" — use "cannot" "it's" — use "it is" "they're" — use "they are" "won't" — use "will not"

Colloquialisms and informal phrases: "a lot of" — use "many" or "a significant number of" "kids" — use "children" "get" — use "obtain," "receive," or "achieve" depending on context "show" — use "demonstrate," "reveal," or "indicate" depending on context "big" — use "significant," "substantial," or "considerable" "look at" — use "examine," "analyze," or "investigate"

First person in inappropriate contexts: First person — I, we, my — is appropriate in some dissertation contexts, particularly in autoethnographic and qualitative research where the researcher's positionality is part of the argument. But it is inappropriate in literature review sections, historical analysis, and anywhere the writing should maintain scholarly objectivity. Know when first person is appropriate in your field and apply it consistently.

How to fix it:

Do a global search for contractions using Find and Replace — search for n't, I'm, it's, and other common contractions and replace them with the full forms. Then read through each chapter specifically listening for informal language and replace colloquialisms with formal academic equivalents.

Mistake 7 — Inconsistent Verb Tense

Verb tense inconsistency is a persistent problem in doctoral dissertations — particularly in the literature review and methodology chapters where students frequently shift between past and present tense without a consistent rationale.

General verb tense conventions for doctoral dissertations:

Literature review: Scholars typically use present tense to describe what existing sources argue — "Collins argues that..." or "Crenshaw demonstrates that..." — because the work and its claims exist in the present.

Historical narrative: Historical events and actions are described in past tense — "The 1996 welfare reform legislation established..."

Methodology: Research procedures already completed are described in past tense — "Participants were selected using..." Data and findings are also typically in past tense.

Discussion and conclusion: Interpretations and implications can use either present or past tense depending on whether you are describing what the data show (present) or what the study found (past).

The key is consistency within each section — not necessarily the same tense throughout the entire dissertation but a consistent tense logic within each chapter and section.

How to fix it:

Go through each chapter of your dissertation and identify the primary tense convention for that chapter. Read through the chapter specifically looking for tense shifts. When you find an inconsistent tense ask whether the shift is intentional and rhetorically justified — if not correct it.

Mistake 8 — Underdeveloped Analysis

One of the most common feedback comments doctoral committees give is that the analysis is underdeveloped — that the student presents evidence but does not analyze it sufficiently. This is a writing problem as much as a thinking problem because analysis must be written — it is not enough to present evidence and expect the reader to draw their own conclusions.

Signs of underdeveloped analysis in dissertation writing:

Paragraphs that present a quote or statistic and then immediately move to the next point without explanation
Sections that describe what sources say without explaining what they mean for your argument
Evidence that is presented but never connected to the research question
Conclusions that are stated without being derived from the evidence presented
Transitions that jump directly from evidence to the next topic without analytical commentary

How to fix it:

After every piece of evidence — every quote, every statistic, every example — ask yourself three questions: What does this evidence mean? How does it support my argument? Why does it matter for my research question? The answers to these three questions are your analysis. Write them out explicitly. Do not assume your reader will draw the same conclusions you did — show the reasoning explicitly.

Mistake 9 — Hedging Language Overuse

Academic writing requires epistemic humility — acknowledging the limits of your claims and the degree of certainty your evidence supports. But many doctoral students overuse hedging language to the point where their argument loses force and clarity.

Appropriate hedging acknowledges genuine uncertainty: "The evidence suggests..." — appropriate when the evidence is suggestive rather than conclusive "This may indicate..." — appropriate when the interpretation is one of several possibilities

Excessive hedging weakens strong claims: "It could perhaps be argued that this might suggest..." — three hedges in one sentence "It seems possible that there may be some evidence that..." — the argument is lost entirely

How to fix it:

Review your dissertation for hedging language and evaluate each instance honestly. Is the hedge necessary because the claim genuinely requires qualification — or is it there because you are uncomfortable making a strong claim? If the evidence supports a direct claim make it directly. Reserve hedging for claims where genuine uncertainty exists.

Mistake 10 — Failure to Define and Use Theoretical Terms Consistently

Doctoral dissertations typically introduce and use specialized theoretical terms — controlling images, intersectionality, afterlife of slavery, racialized patriarchy, and so on. These terms must be defined clearly on first use and then used consistently throughout the dissertation with exactly the same meaning.

Common terminology mistakes:

Undefined terms: Using a theoretical term without defining it leaves readers — including committee members outside your specific subfield — without the foundation they need to follow your argument.

Inconsistent use: Defining a term one way in chapter one and using it with a slightly different meaning in chapter three signals imprecise thinking and imprecise writing.

Synonymous variation: Using different terms for the same concept in different chapters — calling it "racialized gender ideology" in one place and "gendered racial ideology" in another — creates confusion about whether you mean the same thing or something different.

How to fix it:

Create a terminology list for your dissertation — a personal reference document showing every specialized term you use, its definition as used in your dissertation, and the chapter where it is first introduced and defined. Check every use of each term throughout the dissertation against this list for consistency.

Mistake 11 — Repetition and Redundancy Across Chapters

Doctoral dissertations are long documents and it is easy — especially after years of writing — to repeat the same points, the same background information, or the same citations in multiple chapters. Some repetition is deliberate and appropriate — restating a key theoretical point at the beginning of a new chapter as an anchor for the reader. But unintentional repetition wastes the reader's time and signals that the dissertation was not carefully reviewed for coherence before submission.

Common forms of repetition in dissertations:

Restating the research question in full in every chapter: The research question should be briefly restated in the introduction to each chapter — but not quoted in full from the introduction chapter every time.

Repeating background information: Historical or contextual background introduced in the introduction chapter does not need to be repeated in the literature review or methodology chapters.

Citing the same source for the same point multiple times: If a source has already established a point earlier in the dissertation a brief reminder citation is sufficient — the full explanation does not need to be repeated.

How to fix it:

Read your dissertation with fresh eyes — ideally after taking a break of at least a few days from the document — and specifically look for places where you recognize text or ideas you have already seen earlier in the dissertation. Cut or condense repeated content ruthlessly. If a point is important enough to make twice make it deliberately and briefly the second time — not by accident and at full length.

Mistake 12 — Writing That Does Not Sound Like a Doctoral Dissertation

This is the hardest mistake to define but the easiest for a committee to recognize. It is the overall register and tone of the writing — whether it sounds like a doctoral-level scholarly argument or like an undergraduate essay, a journalistic article, or a personal reflection.

Signs that dissertation writing does not meet doctoral-level register:

Short, choppy sentences that lack analytical complexity
Informal conversational phrasing throughout
Opinionated statements without scholarly support
Absence of engagement with theoretical frameworks
Writing that describes rather than analyzes
Absence of the qualifying, nuancing language that characterizes mature scholarly argument

How to fix it:

Read published academic articles and book chapters in your field and pay close attention not just to what they argue but how they argue it — the sentence structures, the vocabulary, the way evidence is introduced and analyzed, the way arguments are qualified and nuanced. Then read a section of your dissertation immediately afterward and listen for the difference. Where your writing sounds less sophisticated than the published scholarship that is where your register needs to be elevated.

Dissertation Writing Quality Checklist

Before submitting your dissertation use this writing quality checklist:

Passive voice minimized throughout — active voice used wherever possible

No vague language — all claims are specific and attributed
Every paragraph has a clear topic sentence
Every paragraph develops one idea completely with evidence and analysis
Transitions are present and clear between paragraphs, sections, and chapters
No contractions or informal language anywhere in the academic text
Verb tense is consistent within each chapter and section

Writing register is appropriate for doctoral-level academic scholarship throughout

Getting Your Dissertation Writing Right

Writing quality is not a minor concern in a doctoral dissertation — it is one of the primary standards by which your scholarship is evaluated. A dissertation with strong research and weak writing fails to communicate the value of the research. A dissertation with strong writing elevates the research and makes the argument compelling, accessible, and credible.

At Two Dissertation Moms we review dissertation writing quality as part of our comprehensive dissertation editing service. We correct passive voice, wordiness, vague language, weak paragraph structure, missing transitions, informal language, tense inconsistencies, underdeveloped analysis, and terminology inconsistencies throughout your dissertation. We do not rewrite your argument — we ensure that the writing serves your argument as effectively as possible.

We work with doctoral students across all disciplines — humanities, social sciences, education, health sciences, STEM, and business — using Turabian, Chicago, APA, and MLA style manuals at universities across the United States and internationally.

FAQ Section:

Q: What are the most common dissertation writing mistakes doctoral students make?

A: The most common dissertation writing mistakes include overuse of passive voice, wordiness and redundancy, vague and imprecise language, weak paragraph structure, unclear or missing transitions, use of contractions and informal language, inconsistent verb tense, underdeveloped analysis, excessive hedging language, and inconsistent use of theoretical terms. These mistakes are predictable, recurring, and entirely preventable with careful review before submission.

Q: Should I use passive voice in my doctoral dissertation?

A: Passive voice should be used sparingly and deliberately in doctoral dissertations. While passive voice is not always wrong chronic overuse produces indirect, imprecise, and difficult-to-follow writing. Use active voice wherever possible and reserve passive voice for situations where the actor is genuinely unknown, unimportant, or deliberately unspecified.

Q: Can I use first person in my doctoral dissertation?

A: First person — I, we, my — is appropriate in some dissertation contexts, particularly in autoethnographic, qualitative, and reflexive research where the researcher's positionality is part of the argument. It is typically inappropriate in literature review sections and historical analysis. Whether first person is appropriate depends on your field, your methodology, and your institution's conventions. Confirm with your committee chair.

Q: How do I improve the writing quality of my doctoral dissertation?

A: Read your dissertation with fresh eyes — ideally after taking a break from it — and specifically look for passive voice, vague language, wordiness, weak paragraph structure, and missing transitions. Read published scholarly work in your field and compare the register and analytical depth to your own writing. Consider having your dissertation reviewed by a professional dissertation editor who specializes in doctoral-level academic writing.

Q: What does underdeveloped analysis look like in a dissertation?

A: Underdeveloped analysis appears as paragraphs that present evidence — a quote, a statistic, an example — without explaining what the evidence means, how it supports the argument, or why it matters for the research question. A fully developed analytical paragraph states the idea, presents the evidence, analyzes the evidence explicitly, and connects it back to the broader argument.

Q: How do I fix verb tense inconsistencies in my dissertation?

A: Identify the primary tense convention for each chapter — present tense for literature review claims, past tense for historical narrative and completed research procedures. Read through each chapter specifically looking for tense shifts. Correct inconsistent tenses and ensure the tense logic within each chapter is consistent throughout.
