Which is NOT considered a credible research source?

Personal blogs are typically not considered a credible research source because they often lack the rigorous peer-review process and accountability that characterize more reliable sources. Unlike government publications, colleges and universities, and testing and standards organizations, personal blogs may reflect individual opinions, experiences, or interpretations without substantial evidence or factual support. This makes them less reliable for academic or professional research, where accuracy and credibility are paramount. In research contexts, the integrity of the source is critical, and personal blogs often do not meet the standards required for credible information.
