Found in 2-4% of dissertations we analyze. Phrases like "All research shows" or "It is universally accepted" tell your committee you haven't actually read the research carefully enough.
Add 2-3 citations or replace the sweeping phrase with specific language.
A sweeping claim is a statement so broad that it can't possibly be true as written. "All teachers struggle with technology." "Research universally supports this approach." "Every student benefits from differentiated instruction." These aren't arguments — they're slogans. And your committee will treat them accordingly.
The problem with sweeping claims goes deeper than missing citations. Even if you could cite a source, no single study proves that ALL of anything does ANYTHING. Academic research deals in evidence, probability, and nuance. When you write "All research shows," you're claiming a consensus that almost certainly doesn't exist — and your committee knows it. They've read the exceptions. They've seen the conflicting findings. Your sweeping claim tells them you haven't.
The fix is straightforward: replace absolute language with precise language. "All" becomes "multiple studies" or "a growing body of research." "Never" becomes "rarely" or "in few documented cases." "Universally" becomes "widely" or "in the majority of reviewed studies." Then back it up with 2-3 citations. You're not weakening your argument — you're making it defensible.
Claims like "All research shows..." invite immediate skepticism. Committees know the literature well enough to recognize overgeneralizations, which weaken your academic credibility and suggest imprecise thinking.
Extensive research has established this link (Martinez, 2020).
Multiple studies have established this link (Martinez, 2020; Chen, 2019; Williams, 2021).
Replace "All research shows" with a quantified claim supported by multiple citations.
All research shows that teacher burnout leads to decreased student performance.
Multiple studies have linked teacher burnout to decreased student performance (Maslach & Leiter, 2016; Skaalvik & Skaalvik, 2017; Madigan & Kim, 2021).
"Universally accepted" ignores documented exceptions — add nuance and citations.
It is universally accepted that technology improves learning outcomes.
Technology integration has been associated with improved learning outcomes in several contexts (Hattie, 2009), though the effect varies by implementation quality and subject area (Cuban, 2013).
"Always" is indefensible. Acknowledging limitations strengthens your argument.
Students always perform better when given choice in assignments.
Student performance tends to improve with assignment choice, particularly when options align with learner interests (Patall et al., 2010), although excessive choice can lead to decision paralysis in some populations (Iyengar & Lepper, 2000).
