Which type of source is typically peer-reviewed and used for scholarly research?

• A. Online encyclopedia
• B. Blog post
• C. Podcast episode
• D. Peer journal

Answer: (D)

Peer-reviewed journals are the type typically used for scholarly research because the articles undergo evaluation by other experts in the field before publication. This peer review checks the rigor of the methods, the accuracy of the data, and the validity of the conclusions, ensuring the work meets professional standards and can be trusted as a credible source. In contrast, online encyclopedia entries, blog posts, and podcast episodes are usually created for broader audiences and do not undergo the same formal expert evaluation, so they don’t carry the same level of scholarly verification. That combination of vetted research and traceable citation makes the peer-reviewed journal the best choice for academic work.
