Found in 5-8% of dissertation paragraphs. "This proves" makes your committee cringe. "This may perhaps somewhat suggest" makes them cringe harder. Get the balance right.
Add appropriate hedging to this absolute claim.
Academic hedging is the art of calibrating the certainty of your claims to the strength of your evidence. It's one of the most nuanced skills in scholarly writing, and getting it wrong in either direction damages your credibility. Say "proves" when you mean "suggests" and your committee questions your understanding of evidence. Say "may possibly indicate" when you have strong evidence, and they question your confidence in your own work.
The most common error in dissertations is absolute language where hedging is needed. "Technology improves student learning" should be "Technology has been associated with improved student learning outcomes in specific contexts." But the second most common error is over-hedging—piling qualifiers until the claim disappears entirely. "The results may potentially suggest that there might be a possible relationship" says nothing. Your committee wants to see that you can commit to what the evidence actually supports.
The key is matching your hedging to the evidence hierarchy. Correlational studies warrant "is associated with." Experimental studies warrant "resulted in" or "demonstrated." Meta-analyses warrant "the evidence consistently supports." Single qualitative studies warrant "participants reported" or "the findings suggest." When your hedge matches your evidence, you sound like a scholar who understands the limits and strengths of the research.
Academic writing avoids absolutes ("always," "never," "proves") because research has limitations. Appropriate hedging shows scholarly caution and prevents overgeneralization.
Students often mistake hedging for weakness. In everyday communication, "might" and "may" sound uncertain. But in academic writing, hedging is a sign of intellectual maturity—it shows you understand the limits of evidence and won't overclaim.
Think of hedging as precision, not weakness. "Proves" is almost never accurate. "Demonstrates" is rarely justified. "Suggests" is honest. Your committee will trust a careful scholar more than an overclaiming one.
This study proves that social media always causes depression in teenagers.
This study suggests that social media use may be associated with increased depression symptoms in some adolescent populations.
"Always leads to" is an absolute causal claim. Hedge appropriately and add conditions.
Professional development always leads to improved teaching quality.
Professional development has been associated with improved teaching quality, particularly when sustained over multiple semesters and focused on content-specific pedagogy (Desimone, 2009).
Five hedges in one sentence obliterate the claim. The statistical evidence warrants a direct statement.
The findings may potentially suggest that there could possibly be some kind of relationship between leadership and culture.
The findings suggest a positive relationship between transformational leadership practices and school culture (beta = .42, p < .01).
Social science data rarely 'prove' anything. Report what the data show with appropriate precision.
The data clearly prove that the intervention was successful.
The data indicate that participants in the intervention group demonstrated statistically significant gains in reading fluency compared to the control group (t(48) = 3.21, p = .002, d = 0.91).
