Research papers should <u>synthesize ideas from sources</u> in order to show the writer's own point of view.
Instead of quoting directly a full source, a professional research paper must contain a <u>summarized</u> analysis or viewpoint from other sources' ideas to support the researcher's arguments.
Citing an author, and explaining his/her ideas in a concise and synthesized manner, can provide a strong <u>validity</u> and <u>relevance</u> to a research paper.
