Which practice helps ensure credibility?

• A. Having research critically reviewed by other scientists.
• B. Reducing sample size.
• C. Hiding data from the public.
• D. Repeating experiments without documenting changes.

Answer: (A)

Peer review by other scientists plays a crucial role in building scientific credibility because it subjects methods, data, and conclusions to independent scrutiny. When work is evaluated by experts, they assess the study design, sample size, analyses used, and whether the data truly support the conclusions. This process helps catch flawed designs, biased interpretations, or unsupported claims, and often leads to clearer, more transparent reporting before results are shared more broadly. It also signals that the work has met a standard of quality the scientific community expects. Reducing the sample size weakens statistical power and increases the chance of misleading results, making findings less credible. Hiding data from the public erodes transparency and prevents others from verifying analyses. Repeating experiments without documenting changes makes it impossible to track what was done or reproduce the results, which undermines trust in the findings.
