With the large amount of news currently being published online, the ability to evaluate the credibility of online news has become essential. While there are many studies involving fake news and tools on how to detect it, there is a limited amount of work that focuses on the use of information literacy to assist people to critically access online information and news. Critical thinking, as a form of information literacy, provides a means to critically engage with online content, for example by looking for evidence to support claims and by evaluating the plausibility of arguments. The purpose of this study is to investigate the current state of knowledge on the use of critical thinking to identify fake news. A systematic literature review (SLR) has been performed to identify previous studies on evaluating the credibility of news, and in particular to see what has been done in terms of the use of critical thinking to evaluate online news. During the SLR’s sifting process, 22 relevant studies were identified. Although some of these studies referred to information literacy, only three explicitly dealt with critical thinking as a means to identify fake news. The studies on critical thinking noted critical thinking as an essential skill for identifying fake news. The recommendation of these studies was that information literacy be included in academic institutions, specifically to encourage critical thinking.
