Essay Revision Series #5: Does your conclusion claim more than your evidence shows?

One useful final check is to compare the strength of your wording with the strength of your evidence.

Words like “proves,” “causes,” and “always” can make a claim sound more certain than the research allows.

Consider this hypothetical example—not a finding from a specific study:

Observation: Students who reported spending more time studying also received higher grades.
Overstatement: Spending more time studying causes higher grades.

The observation alone does not establish causation. Other factors, such as prior knowledge or study methods, could help explain the relationship.

A more accurate summary of that observation would be:

“More reported study time was associated with higher grades in this sample.”

Notice two changes: the sentence describes an association, and it keeps the claim within the sample studied.

That does not mean you should weaken every sentence or simply add “may” everywhere. The goal is to match your claim to what the research design and findings actually support.

Today’s revision task:

Find one sentence containing “proves,” “causes,” “all,” or “always.” Return to the source and check:

• Does the study support that level of certainty?
• Does it support a causal claim?
• Does your sentence extend beyond the people or conditions studied?

Following yesterday’s tip about comparing sources, this step helps you avoid drawing a broader conclusion than those sources justify.

Have you received feedback such as “overstated” or “too strong”? Which part was hardest to revise?
