Wikipedia is not generally considered a credible source on its own. This is because Wikipedia is an open-access platform that anyone can edit at any time. Thus, while Wikipedia can be helpful when just starting out in your research, it should not be cited among your sources in your final paper.
However, you can use the references cited in Wikipedia articles to access the research materials the articles are based on. If a Wikipedia article cites academic sources such as journal articles, go directly to these sources to perform more in-depth research. These sources can be used to support your paper.
