Found in 8-12% of dissertation paragraphs. "Somewhat effective," "fairly common," "tends to impact"—your committee reads these as "I'm not sure, but here's a guess."
Replace vague terms with specific, measurable language.
Vague language in a dissertation isn't just a style issue—it's a credibility issue. When you write "the intervention was somewhat effective" instead of "the intervention produced a moderate effect size (d = 0.45)," you're replacing evidence with impression. Your committee has seen enough dissertations to know that vague language usually means the writer either doesn't know the specifics or is trying to avoid committing to a clear position.
The AI-powered version of this check goes beyond the free instant pattern matching that catches obvious vague words. It analyzes context to determine whether seemingly precise language is actually vague in practice. "The results were significant" sounds precise but means nothing without a p-value. "The participants experienced challenges" sounds descriptive but could mean anything from mild inconvenience to insurmountable barriers. Context matters, and the AI evaluates it.
Vague language is a conceptual trap because it often feels like good academic writing. Hedging with "somewhat," "fairly," or "tends to" can feel like appropriate scholarly caution. But there's a crucial difference between appropriate hedging ("The evidence suggests a moderate positive relationship") and lazy vagueness ("It is somewhat related to some extent"). The first shows nuanced thinking. The second shows unclear thinking.
Academic writing demands precision. Terms like "significant," "various," or "improved" without context are meaningless—committees need to know exactly what you mean.
Words like "significant," "meaningful," and "various" feel scholarly because we see them in academic writing. But experienced researchers use these words precisely—"significant" means statistically significant, "meaningful" has a defined threshold. When students use them as generic intensifiers, it signals imprecision.
Every time you write "significant," "meaningful," "important," or "various," challenge yourself: "Can I replace this with a number, a name, or a specific descriptor?" If not, the word is probably hiding a gap in your thinking.
The intervention significantly improved outcomes across various measures.
The intervention improved reading scores by 15% (p < .01) across three standardized assessments.
"Somewhat successful" and "to a certain degree" are double vague. Replace with the actual result.
The program was somewhat successful in improving student outcomes to a certain degree.
The program improved reading comprehension scores by an average of 12 percentile points over the control group (Thompson, 2022).
"Various," "tend to," and "certain types" are all vague. Name the issues, the impact, and the schools.
There are various issues that tend to impact teacher retention in certain types of schools.
Three factors disproportionately drive teacher attrition in Title I schools: inadequate compensation, insufficient administrative support, and high student behavioral needs (Ingersoll et al., 2021).
In your limitations section, name the specific limitations and their specific consequences.
The study had some limitations that may have affected the results.
The study's reliance on self-reported survey data and its small sample size (N = 23) limit the generalizability of these findings to larger school districts.
