Academic Reading #7: Judge Claims, Methods, and Limits
Judge Claims, Methods, and Limits
Ask what the study supports—and how far it reaches.
Critical reading means checking the link between a claim and its evidence. You can respect a study while still asking careful questions.

Turn a claim into questions
What was compared? What was changed by the researchers? What was only observed? What was the sample, and what counted as a result? In an experiment, inspect the control or comparison condition. In an observational study, ask whether other factors could explain the relationship. In a simulation, identify the assumptions and the data used to test the model.
Understand association and causation
If two measurements vary together, they are associated. That alone does not establish that one causes the other. For example, an invented survey might link laboratory experience with faster reading. Prior knowledge, field, or study habits could also matter. A causal interpretation needs a design and reasoning that address plausible alternatives.
Treat cautious language as information
“Suggests,” “may,” “is consistent with,” and “under these conditions” tell you the strength and scope of a claim. They are not words to remove when making the English simpler. Also distinguish a hypothesis from a result. “We expected…” describes a prediction made before the findings; the study may produce a different answer.
Read limitations as a research plan
Ask what the sample represents and where the result might change. A single material, location, or task cannot represent every situation. Look for missing controls, alternative explanations, and future tests. A limitation does not automatically make a paper useless. It tells you what the evidence can answer and what another study must investigate.
Your reading task
Improve this exaggerated summary: “The study proves that faster learning always reduces performance.” Include the study context and one limit.
Open the model answer or self-check
A safer summary is: “In this bee study, faster learning was associated with fewer days of foraging. The result concerns one learning task and setting; it does not show that faster learning always reduces performance.”
Inspect the paper’s methods and discussion
Find one proposed explanation and one stated limitation. Write a follow-up question that a new experiment could address.
