What Overgeneralisation Looks Like
Overgeneralisation happens when a claim reaches further than the evidence supporting it. It is one of the most common reasons Malaysian examiners write “too sweeping” or “not supported” in the margins of a discussion chapter. A study of 120 undergraduates at one Malaysian university cannot support the sentence “Students prefer online learning” — that sentence claims something about all students everywhere, while the data speaks only about a specific sample in a specific context. The gap between what was measured and what is asserted is where overgeneralisation lives, and it weakens otherwise sound research by making claims the writer cannot defend in the viva.
Scaling Your Claims to Your Evidence
The fix is to match the scope of every claim to the scope of your data. Three adjustments do most of the work. First, specify the population: “the undergraduates surveyed in this study” rather than “students” in general. Second, add hedging where the evidence is suggestive rather than conclusive: “the findings suggest” or “this may indicate” instead of “this proves”. Third, restrict universal words — all, every, always, none, never — which almost never hold true in social research and invite an examiner to find the single counterexample that breaks the claim. “Most respondents” or “the majority of participants” is defensible; “all students” rarely is. Hedging is not weakness here; it is precision, and experienced readers trust a writer who claims exactly what the data shows.
Checking for Overgeneralisation During Revision
Treat overgeneralisation as a dedicated revision pass rather than something you catch by chance. Read your discussion and conclusion chapters with one question in mind: could I defend this exact sentence if an examiner asked “based on what evidence?” Flag every claim that quietly expands from your sample to people in general, from one context to all contexts, or from correlation to cause. Pay particular attention to the opening sentences of paragraphs and to your conclusion, where writers tend to inflate findings to sound more impressive. The strongest theses are often the most modest in their wording — they claim narrowly and support each claim fully. Narrowing an overgeneralised statement does not shrink your contribution; it makes the contribution credible, which is what protects you when the same sentence is read aloud in the examination room. A useful habit is to pair every broad-sounding claim with an explicit reminder of its boundary — “within the context of this single institution” or “among the participants studied” — so that the limitation travels with the claim instead of being quarantined in your limitations section, where examiners often suspect it was added as an afterthought.
