How do you evaluate the credibility of sources in a seminar?

• A. Publication date only.
• B. Consider author expertise, publication venue, methodology, sample size, reproducibility, and consistency with other evidence.
• C. Popularity on social media.
• D. Personal acquaintance with author.

Answer: (B)

Evaluating credibility means weighing how trustworthy the information is by looking at how it was created and how it fits with what else we know. The best approach is to consider several factors together: who wrote it and what they know (author expertise), where it’s published and the standards of that venue (publication venue), how the work was done (methodology), how many subjects or data points were used (sample size), whether others can repeat the work and get the same results (reproducibility), and whether the findings align with other credible evidence (consistency with other evidence). For example, a study published in a respected, peer‑reviewed journal with a clear design, appropriate controls, a decent sample size, transparent data or preregistration, and results that match or coherently extend existing research is generally more trustworthy. In contrast, relying on the publication date alone doesn’t speak to quality, popularity on social media doesn’t reflect rigor, and personal familiarity with an author may indicate bias without guaranteeing accuracy. So, using a combination of these criteria helps you judge credibility more reliably.
