Which statement about the evaluation of peer review is true?

• A. It helps to establish validity and accuracy of research.
• B. Anonymity could lead to reviewers being overcritical.
• C. Changing data that is correct could give inaccurate results.
• D. Publication bias can occur when only positive results are published.

Answer: (A)

Evaluating peer review centers on whether the research is sound and the conclusions justified. Reviewers examine the study design, data collection, analyses, and interpretation to see if the methods are appropriate, the data support the claims, and any biases are acknowledged. This process helps establish validity and accuracy because it catches flawed methods, incorrect analyses, or overstated conclusions before publication, boosting confidence in the results. Other points relate to broader issues in science, but they aren’t the core aim of the evaluation. Anonymity can influence reviewer behavior, but it isn’t what the evaluation primarily seeks to establish. Deliberately changing data would corrupt the research, which is contrary to the purpose of review. Publication bias is a recognized problem in science, but it describes publishing practices rather than what the peer-review process evaluates.
