What are the differences between research and non-research articles in terms of content, credibility, and impact on the readers?

Research articles are based on original research studies and present findings, methodology, and analysis. They are typically peer-reviewed and provide a high level of credibility due to the rigorous research process. Non-research articles, on the other hand, are often opinion pieces, reviews, or summaries of existing knowledge. They may lack the same level of credibility as research articles but can still be informative and engaging for readers. Research articles have a greater impact on readers as they contribute new knowledge to the field, while non-research articles may be more accessible and easier to understand for a general audience.
