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.

Introduction

The information age has brought a significant increase in available sources of information; this is in line with the unparalleled increase in internet availability and connection, in addition to the accessibility of technological devices [ 1 ]. People no longer rely on television and print media alone for obtaining news, but increasingly make use of social media and news apps. The variety of information sources that we have today has contributed to the spread of alternative facts [ 1 ]. With over 1.8 billion active users per month in 2016 [ 2 ], Facebook accounted for 20% of total traffic to reliable websites and up to 50% of all the traffic to fake news sites [ 3 ]. Twitter comes second to Facebook, with over 400 million active users per month [ 2 ]. Posts on social media platforms such as Facebook and Twitter spread rapidly due to how they attempt to grab the readers’ attention as quickly as possible, with little substantive information provided, and thus create a breeding ground for the dissemination of fake news [ 4 ].

While social media is a convenient way of accessing news and staying connected to friends and family, it is not easy to distinguish real news from fake news on social media [ 5 ]. Social media continues to contribute to the increasing distribution of user-generated information; this includes hoaxes, false claims, fabricated news and conspiracy theories, with primary sources being social media platforms such as Facebook and Twitter [ 6 ]. This means that any person who is in possession of a device, which can connect to the internet, is potentially a consumer or distributor of fake news. While social media platforms and search engines do not encourage people to believe the information being circulated, they are complicit in people’s propensity to believe the information they come across on these platforms, without determining their validity [ 6 ]. The spread of fake news can cause a multitude of damages to the subject; varying from reputational damage of an individual, to having an effect on the perceived value of a company [ 7 ].

The purpose of this study is to investigate the use of critical thinking methods to detect news stories that are untrue or otherwise help to develop a critical attitude to online news. This work was performed by means of a systematic literature review (SLR). The paper is presented as follows. The next section provides background information on fake news, its importance in the day-to-day lives of social media users and how information literacy and critical thinking can be used to identify fake news. Thereafter, the SLR research approach is discussed. Following this, the findings of the review are reported, first in terms of descriptive statistics and the in terms of a thematic analysis of the identified studies. The paper ends with the Conclusion and recommendations.

Background: Fake News, Information Literacy and Critical Thinking

This section discusses the history of fake news, the fake news that we know today and the role of information literacy can be used to help with the identification of fake news. It also provides a brief definition of critical thinking.

The History of Fake News

Although fake news has received increased attention recently, the term has been used by scholars for many years [ 4 ]. Fake news emerged from the tradition of yellow journalism of the 1890s, which can be described as a reliance on the familiar aspects of sensationalism—crime news, scandal and gossip, divorces and sex, and stress upon the reporting of disasters, sports sensationalism as well as possibly satirical news [ 5 ]. The emergence of online news in the early 2000s raised concerns, among them being that people who share similar ideologies may form “echo chambers” where they can filter out alternative ideas [ 2 ]. This emergence came about as news media transformed from one that was dominated by newspapers printed by authentic and trusted journalists to one where online news from an untrusted source is believed by many [ 5 ]. The term later grew to describe “satirical news shows”, “parody news shows” or “fake-news comedy shows” where a television show, or segment on a television show was dedicated to political satire [ 4 ]. Some of these include popular television shows such as The Daily Show (now with Trevor Noah), Saturday Night Live ’s “The Weekend Update” segment, and other similar shows such as Last Week Tonight with John Oliver and The Colbert Report with Stephen Colbert [ 4 ]. News stories in these shows were labelled “fake” not because of their content, but for parodying network news for the use of sarcasm, and using comedy as a tool to engage real public issues [ 4 ]. The term “Fake News” further became prominent during the course of the 2016 US presidential elections, as members of the opposing parties would post incorrect news headlines in order to sway the decision of voters [ 6 ].

Fake News Today

The term fake news has a more literal meaning today [ 4 ]. The Macquarie Dictionary named fake news the word of the year for 2016 [ 8 ]. In this dictionary, fake news is described it as a word that captures a fascinating evolution in the creation of deceiving content, also allowing people to believe what they see fit. There are many definitions for the phrase, however, a concise description of the term can be found in Paskin [ 4 ] who states that certain news articles originating from either social media or mainstream (online or offline) platforms, that are not factual, but are presented as such and are not satirical, are considered fake news. In some instances, editorials, reports, and exposés may be knowingly disseminating information with intent to deceive for the purposes of monetary or political benefit [ 4 ].

A distinction amongst three types of fake news can be made on a conceptual level, namely: serious fabrications, hoaxes and satire [ 3 ]. Serious fabrications are explained as news items written on false information, including celebrity gossip. Hoaxes refer to false information provided via social media, aiming to be syndicated by traditional news platforms. Lastly, satire refers to the use of humour in the news to imitate real news, but through irony and absurdity. Some examples of famous satirical news platforms in circulation in the modern day are The Onion and The Beaverton , when contrasted with real news publishers such as The New York Times [ 3 ].

Although there are many studies involving fake news and tools on how to detect it, there is a limited amount of academic work that focuses on the need to encourage information literacy so that people are able to critically access the information they have been presented, in order to make better informed decisions [ 9 ].

Stein-Smith [ 5 ] urges that information/media literacy has become a more critical skill since the appearance of the notion of fake news has become public conversation. Information literacy is no longer a nice-to-have proficiency but a requirement for interpreting news headlines and participation in public discussions. It is essential for academic institutions of higher learning to present information literacy courses that will empower students and staff members with the prerequisite tools to identify, select, understand and use trustworthy information [ 1 ]. Outside of its academic uses, information literacy is also a lifelong skill with multiple applications in everyday life [ 5 ]. The choices people make in their lives, and opinions they form need to be informed by the appropriate interpretation of correct, opportune, and significant information [ 5 ].

Critical Thinking

Critical thinking covers a broad range of skills that includes the following: verbal reasoning skills; argument analysis; thinking as hypothesis testing; dealing with likelihood and uncertainties; and decision making and problem solving skills [ 10 ]. For the purpose of this study, where we are concerned with the evaluation of the credibility of online news, the following definition will be used: critical thinking is “the ability to analyse and evaluate arguments according to their soundness and credibility, respond to arguments and reach conclusions through deduction from given information” [ 11 ]. In this study, we want to investigate how the skills mentioned by [ 11 ] can be used as part of information literacy, to better identify fake news.

The next section presents the research approach that was followed to perform the SLR.

Research Method

This section addresses the research question, the search terms that were applied to a database in relation to the research question, as well as the search criteria used on the search results. The following research question was addressed in this SLR:

• What is the role of critical thinking in identifying fake news, according to previous studies?

The research question was identified in accordance to the research topic. The intention of the research question is to determine if the identified studies in this review provide insights into the use of critical thinking to evaluate the credibility of online news and in particular to identify fake news.

Delimitations.

In the construction of this SLR, the following definitions of fake news and other related terms have been excluded, following the suggestion of [ 2 ]:

• Unintentional reporting mistakes;
• Rumours that do not originate from a particular news article;
• Conspiracy theories;
• Satire that is unlikely to be misconstrued as factual;
• False statements by politicians; and
• Reports that are slanted or misleading, but not outright false.

Search Terms.

The database tool used to extract sources to conduct the SLR was Google Scholar ( https://scholar.google.com ). The process for extracting the sources involved executing the search string on Google Scholar and the retrieval of the articles and their meta-data into a tool called Mendeley, which was used for reference management.

The search string used to retrieve the sources was defined below:

(“critical think*” OR “critically (NEAR/2) reason*” OR “critical (NEAR/2) thought*” OR “critical (NEAR/2) judge*” AND “fake news” AND (identify* OR analyse* OR find* OR describe* OR review).

To construct the search criteria, the following factors have been taken into consideration: the research topic guided the search string, as the key words were used to create the base search criteria. The second step was to construct the search string according to the search engine requirements on Google Scholar.

Selection Criteria.

The selection criteria outlined the rules applied in the SLR to identify sources, narrow down the search criteria and focus the study on a specific topic. The inclusion and exclusion criteria are outlined in Table  1 to show which filters were applied to remove irrelevant sources.

Table 1.

Inclusion and exclusion criteria for paper selection

Source Selection.

The search criteria were applied on the online database and 91 papers were retrieved. The criteria in Table  1 were used on the search results in order to narrow down the results to appropriate papers only.

PRISMA Flowchart.

The selection criteria included four stages of filtering and this is depicted in Fig.  1 . In then Identification stage, the 91 search results from Google Scholar were returned and 3 sources were derived from the sources already identified from the search results, making a total of 94 available sources. In the screening stage, no duplicates were identified. After a thorough screening of the search results, which included looking at the availability of the article (free to use), 39 in total records were available – to which 55 articles were excluded. Of the 39 articles, nine were excluded based on their titles and abstract being irrelevant to the topic in the eligibility stage. A final list of 22 articles was included as part of this SLR. As preparation for the data analysis, a data extraction table was made that classified each article according to the following: article author; article title; theme (a short summary of the article); year; country; and type of publication. The data extraction table assisted in the analysis of findings as presented in the next section.

Analysis of Findings

Descriptive statistics.

Due to the limited number of relevant studies, the information search did not have a specified start date. Articles were included up to 31 August 2019. The majority of the papers found were published in 2017 (8 papers) and 2018 (9 papers). This is in line with the term “fake news” being announced the word of the year in the 2016 [ 8 ].

The selected papers were classified into themes. Figure  2 is a Venn diagram that represents the overlap of articles by themes across the review. Articles that fall under the “fake news” theme had the highest number of occurrences, with 11 in total. Three articles focused mainly on “Critical Thinking”, and “Information Literacy” was the main focus of four articles. Two articles combined all three topics of critical thinking, information literacy, and fake news.

Venn diagram depicting the overlap of articles by main focus

An analysis of the number of articles published per country indicate that the US had a dominating amount of articles published on this topic, a total of 17 articles - this represents 74% of the selected articles in this review. The remaining countries where articles were published are Australia, Germany, Ireland, Lebanon, Saudi Arabia, and Sweden - with each having one article published.

In terms of publication type, 15 of the articles were journal articles, four were reports, one was a thesis, one was a magazine article and one, a web page.

Discussion of Themes

The following emerged from a thematic analysis of the articles.

Fake News and Accountability.

With the influence that social media has on the drive of fake news [ 2 ], who then becomes responsible for the dissemination and intake of fake news by the general population? The immediate assumption is that in the digital age, social media platforms like Facebook and Twitter should be able to curate information, or do some form of fact-checking when posts are uploaded onto their platforms [ 12 ], but that leans closely to infringing on freedom of speech. While different authors agree that there need to be measures in place for the minimisation of fake news being spread [ 12 , 13 ], where that accountability lies differs between the authors. Metaxas and Mustafaraj [ 13 ] aimed to develop algorithms or plug-ins that can assist in trust and postulated that consumers should be able to identify misinformation, thus making an informed decision on whether to share that information or not. Lazer et al. [ 12 ] on the other hand, believe the onus should be on the platform owners to put restrictions on the kind of data distributed. Considering that the work by Metaxas and Mustafaraj [ 13 ] was done seven years ago, one can conclude that the use of fact-checking algorithms/plug-ins has not been successful in curbing the propulsion of fake news.

Fake News and Student Research.

There were a total of four articles that had a focus on student research in relation to fake news. Harris, Paskin and Stein-Smith [ 4 , 5 , 14 ] all agree that students do not have the ability to discern between real and fake news. A Stanford History Education Group study reveals that students are not geared up for distinguishing real from fake news [ 4 ]. Most students are able to perform a simple Google search for information; however, they are unable to identify the author of an online source, or if the information is misleading [ 14 ]. Furthermore, students are not aware of the benefits of learning information literacy in school in equipping them with the skills required to accurately identify fake news [ 5 ]. At the Metropolitan Campus of Fairleigh Dickson University, librarians have undertaken the role of providing training on information literacy skills for identifying fake news [ 5 ].

Fake News and Social Media.

A number of authors [ 6 , 15 ] are in agreement that social media, the leading source of news, is the biggest driving force for fake news. It provides substantial advantage to broadcast manipulated information. It is an open platform of unfiltered editors and open to contributions from all. According to Nielsen and Graves as well as Janetzko, [ 6 , 15 ], people are unable to identify fake news correctly. They are likely to associate fake news with low quality journalism than false information designed to mislead. Two articles, [ 15 ] and [ 6 ] discussed the role of critical thinking when interacting on social media. Social media presents information to us that has been filtered according to what we already consume, thereby making it a challenge for consumers to think critically. The study by Nielsen and Graves [ 6 ] confirm that students’ failure to verify incorrect online sources requires urgent attention as this could indicate that students are a simple target for presenting manipulated information.

Fake News That Drive Politics.

Two studies mention the effect of social and the spread of fake news, and how it may have propelled Donald Trump to win the US election in 2016 [ 2 , 16 ]. Also, [ 8 ] and [ 2 ] mention how a story on the Pope supporting Trump in his presidential campaign, was widely shared (more than a million times) on Facebook in 2016. These articles also point out how in the information age, fact-checking has become relatively easy, but people are more likely to trust their intuition on news stories they consume, rather than checking the reliability of a story. The use of paid trolls and Russian bots to populate social media feeds with misinformation in an effort to swing the US presidential election in Donald Trump’s favour, is highlighted [ 16 ]. The creation of fake news, with the use of alarmist headlines (“click bait”), generates huge traffic into the original websites, which drives up advertising revenue [ 2 ]. This means content creators are compelled to create fake news, to drive ad revenue on their websites - even though they may not be believe in the fake news themselves [ 2 ].

Information Literacy.

Information literacy is when a person has access to information, and thus can process the parts they need, and create ways in which to best use the information [ 1 ]. Teaching students the importance of information literacy skills is key, not only for identifying fake news but also for navigating life aspects that require managing and scrutinising information, as discussed by [ 1 , 17 ], and [ 9 ]. Courtney [ 17 ] highlights how journalism students, above students from other disciplines, may need to have some form of information literacy incorporated into their syllabi to increase their awareness of fake news stories, creating a narrative of being objective and reliable news creators. Courtney assessed different universities that teach journalism and media-related studies, and established that students generally lack awareness on how useful library services are in offering services related to information literacy. Courtney [ 17 ] and Rose-Wiles [ 9 ] discuss how the use of library resources should be normalised to students. With millennials and generation Z having social media as their first point of contact, Rose-Wiles [ 9 ] urges universities, colleges and other academic research institutes to promote the use of more library resources than those from the internet, to encourage students to lean on reliable sources. Overall, this may prove difficult, therefore Rose-Wiles [ 9 ] proposes that by teaching information literacy skills and critical thinking, students can use these skills to apply in any situation or information source.

Referred to as “truth decay”, people have reached a point where they no longer need to agree with facts [ 18 ]. Due to political polarisation, the general public hold the opinion of being part of an oppressed group of people, and therefore will believe a political leader who appeals to that narrative [ 18 ]. There needs to be tangible action put into driving civil engagement, to encourage people to think critically, analyse information and not believe everything they read.

Critical Thinking.

Only three of the articles had critical thinking as a main theme. Bronstein et al. [ 19 ] discuss how certain dogmatic and religious beliefs create a tendency in individuals to belief any information given, without them having a need to interrogate the information further and then deciding ion its veracity. The article further elaborates how these individuals are also more likely to engage in conspiracy theories, and tend to rationalise absurd events. Bronstein et al.’s [ 19 ] study conclude that dogmatism and religious fundamentalism highly correlate with a belief in fake news. Their study [ 19 ] suggests the use of interventions that aim to increase open-minded thinking, and also increase analytical thinking as a way to help religious, curb belief in fake news. Howlett [ 20 ] describes critical thinking as evidence-based practice, which is taking the theories of the skills and concepts of critical thinking and converting those for use in everyday applications. Jackson [ 21 ] explains how the internet purposely prides itself in being a platform for “unreviewed content”, due to the idea that people may not see said content again, therefore it needs to be attention-grabbing for this moment, and not necessarily accurate. Jackson [ 21 ] expands that social media affected critical thinking in how it changed the view on published information, what is now seen as old forms of information media. This then presents a challenge to critical thinking in that a large portion of information found on the internet is not only unreliable, it may also be false. Jackson [ 21 ] posits that one of the biggest dangers to critical thinking may be that people have a sense of perceived power for being able to find the others they seek with a simple web search. People are no longer interested in evaluation the credibility of the information they receive and share, and thus leading to the propagation of fake news [ 21 ].

Discussion of Findings

The aggregated data in this review has provided insight into how fake news is perceived, the level of attention it is receiving and the shortcomings of people when identifying fake news. Since the increase in awareness of fake news in 2016, there has been an increase in academic focus on the subject, with most of the articles published between 2017 and 2018. Fifty percent of the articles released focused on the subject of fake news, with 18% reflecting on information literacy, and only 13% on critical thinking.

The thematic discussion grouped and synthesised the articles in this review according to the main themes of fake news, information literacy and critical thinking. The Fake news and accountability discussion raised the question of who becomes accountable for the spreading of fake news between social media and the user. The articles presented a conclusion that fact-checking algorithms are not successful in reducing the dissemination of fake news. The discussion also included a focus on fake news and student research , whereby a Stanford History Education Group study revealed that students are not well educated in thinking critically and identifying real from fake news [ 4 ]. The Fake news and social media discussion provided insight on social media is the leading source of news as well as a contributor to fake news. It provides a challenge for consumers who are not able to think critically about online news, or have basic information literacy skills that can aid in identifying fake news. Fake news that drive politics highlighted fake news’ role in politics, particularly the 2016 US presidential elections and the influence it had on the voters [ 22 ].

Information literacy related publications highlighted the need for educating the public on being able to identify fake news, as well as the benefits of having information literacy as a life skill [ 1 , 9 , 17 ]. It was shown that students are often misinformed about the potential benefits of library services. The authors suggested that university libraries should become more recognised and involved as role-players in providing and assisting with information literacy skills.

The articles that focused on critical thinking pointed out two areas where a lack of critical thinking prevented readers from discerning between accurate and false information. In the one case, it was shown that people’s confidence in their ability to find information online gave made them overly confident about the accuracy of that information [ 21 ]. In the other case, it was shown that dogmatism and religious fundamentalism, which led people to believe certain fake news, were associated with a lack of critical thinking and a questioning mind-set [ 21 ].

The articles that focused on information literacy and critical thinking were in agreement on the value of promoting and teaching these skills, in particular to the university students who were often the subjects of the studies performed.

This review identified 22 articles that were synthesised and used as evidence to determine the role of critical thinking in identifying fake news. The articles were classified according to year of publication, country of publication, type of publication and theme. Based on the descriptive statistics, fake news has been a growing trend in recent years, predominantly in the US since the presidential election in 2016. The research presented in most of the articles was aimed at the assessment of students’ ability to identify fake news. The various studies were consistent in their findings of research subjects’ lack of ability to distinguish between true and fake news.

Information literacy emerged as a new theme from the studies, with Rose-Wiles [ 9 ] advising academic institutions to teach information literacy and encourage students to think critically when accessing online news. The potential role of university libraries to assist in not only teaching information literacy, but also assisting student to evaluate the credibility of online information, was highlighted. The three articles that explicitly dealt with critical thinking, all found critical thinking to be lacking among their research subjects. They further indicated how this lack of critical thinking could be linked to people’s inability to identify fake news.

This review has pointed out people’s general inability to identify fake news. It highlighted the importance of information literacy as well as critical thinking, as essential skills to evaluate the credibility of online information.

The limitations in this review include the use of students as the main participants in most of the research - this would indicate a need to shift the academic focus towards having the general public as participants. This is imperative because anyone who possesses a mobile device is potentially a contributor or distributor of fake news.

For future research, it is suggested that the value of the formal teaching of information literacy at universities be further investigated, as a means to assist students in assessing the credibility of online news. Given the very limited number of studies on the role of critical thinking to identify fake news, this is also an important area for further research.

The news and critical thinking: Why is it important?

Every day, we’re bombarded with a huge amount of news and information from all around the world. Whether it’s through websites, social media or TV, it’s never been easier to access the news.

Think about how many bits of news you’ve seen on your social feeds today. Do you know how much of it you can really trust?

What is media literacy and why is it important?

Media literacy is the ability to spot different types of media and to understand the messages they are communicating. It involves questioning what you’re watching, listening to or reading, so that you can make better judgements about the messages you’re being presented with.

Media includes all the different ways a message is communicated – from the news we read online to the ads we see on TV. The media we consume can inform, educate, entertain or convince us. It influences the way we see and think about ourselves and the world around us.

If we have good media literacy, it can stop us from getting stressed out by the confusing or negative things we see in the media. It can also help us focus on all the useful media that helps us to learn, connect and relax.

How can I improve my media literacy?

Question the credibility of the news source.

Whether you read the news from social media or a website, it’s important to know who is publishing the content. A credible or trustworthy news provider will make sure their reporting is impartial and free of errors.

Check out a news provider’s ‘About Us’ section on their website to learn more about their mission, values and approach to reporting. For example, as a not-for-profit, The Conversation ’s mission is ‘to provide access to quality explanatory journalism’ through articles written by ‘academics and journalists working together’. Factors like these will influence the way a story is reported.

Also consider who owns the media company, and if that is impacting the stories being produced. In Australia many publications share a parent company, meaning they may look and feel different, but they’re bound to similar publishing guidelines and rules. Check out a high level overview of Australian media organisations here .

Find news from a variety of sources

Get a balanced picture of news stories by consuming different news sources. This will give you a range of different perspectives on an issue. Media sites are often funded by advertisers, which means their reporting is driven by clicks (how people engage with the content). This causes them to report their stories in certain ways. If a news site is funded by an organisation with a particular political view, it can lead to reporting that promotes their way of thinking.

Read a mix of local publications and international news providers such as Reuters . This will help you to develop a well-informed opinion on a story.

Think about the purpose of the article

Why was the story produced? Was it to:

inform you about something that happened (news report)?

change your mind or behaviour (opinion piece)?

sell you something and promote a brand (branded content)?

A news provider might produce many different types of articles and videos, and should label them to make their purpose clear to the reader.

When it comes to the news, start with reports that contain facts, statistics from a trustworthy source (like from the government or an academic institution) and quotes from experts. Once you have the background details on a story, you’ll be able to make your own conclusions about an opinion piece written in response to it. This is especially important because prejudice against a person or group is common in mainstream media coverage.

Spot misinformation or fake news

Although social media has helped us become better connected, it has also driven the viral spread of fake news, or ‘misinformation’. Fake news is created using false or inaccurate information, with the intention of deceiving the reader. It works by grabbing a reader’s attention with a sensational or wild claim in the hope they’ll then click through and share it.

Social media feeds are based on an algorithm or system of rules that sorts posts based on the type of content you normally interact with and how popular the content is. The more people who interact with the content, the quicker the fake news spreads and the more money the site makes from advertisers who pay to put up their ads on the site. Here are a few signs the story you’re reading could be fake news:

No evidence: It contains no evidence for its claims and is often based on one person’s side of the story.

Sensational headline and images: It uses an outrageous headline and images to lure you in (e.g. ‘Celebrity kills off dad in latest prank’). The stories may also include many bizarre claims.

Not reported anywhere else: If you can’t find the story through any other news source, it’s reasonable to question its credibility.

Contains errors: The article contains spelling and grammatical mistakes or incorrect dates.

Unusual URL: For example, the site URL ends in “.com.co” or “.lo”.

Talk to your family and friends about the news you’re reading

Discussing news stories with other people will challenge and broaden your own perspective. Be open to talking with and listening to people whose views differ from yours.

If the conversation starts to become difficult or makes you feel uncomfortable, ask someone neutral to join the discussion. Or you can always stop the conversation and simply agree to disagree. There’s no point arguing with someone who doesn’t want to listen to anyone else’s perspective. Get some tips on discussing politics with family and friends .

Switch off and take a break

News has a 24-hour cycle – its output is never-ending. It can therefore be overwhelming and exhausting, especially as some media outlets tend to report mostly negative stories (because they get an emotional reaction). Get some tips on coping with disturbing videos and images here .

Turn off the news and do something you enjoy to clear your mind . Challenge yourself to a tech-free hour and spend it going for a walk or reading a book. You could do something that will refresh your mind and body, like shooting some hoops or dancing to your favourite music.

Whatever you decide to do, remember that it’s important to take a break from the news every once in a while. Taking time out helps you to think critically about and not be overwhelmed by the news. It’ll also help you with all the other tips in this article!

Since the 2016 US presidential election, the phrase ‘ fake news ’ has become standard currency. But what does the term actually mean, and how can you distinguish fake from ‘real’ news?

The bad news is that ‘fake news’ is often very believable, and it is extremely easy to get caught out.

This page explains how you can apply critical thinking techniques to news stories to reduce the chances of believing fake news, or at least starting to understand that ‘not everything you read is true’.

What is ‘ Fake News ’?

‘Fake news’ is news stories that are either completely untrue, or do not contain all the truth, with a view to deliberately misleading readers.

Fake news became prominent during the US election, with supporters of both sides tweeting false information in the hope of influencing voters. But it is nothing new.

“The report of my death was an exaggeration.”

In May 1897, Mark Twain, the American author, was in London. Rumours reached the US that he was very ill and, later, that he had died. In a letter to Frank Marshall White, a journalist who inquired after his health as a result, Mark Twain suggested that the rumours had started because his cousin, who shared his surname, had been ill a few weeks before. He noted dryly to White,

“The report of my death was an exaggeration”.

It had, nonetheless, been widely reported in the US, with one newspaper even printing an obituary.

Fake news is not:

Articles on satirical or humorous websites, or related publications, that make a comment on the news by satirising them, because this is intended to inform and amuse, not misinform;

Anything obvious that ‘everyone already knows’ (often described using the caption ‘that’s not news’; or

An article whose content you disagree with.

The deliberate intention of fake news to mislead is crucial.

Why is Fake News a Problem?

If fake news has been around for so long, why is it suddenly a problem?

The answer is that social media means that credible fake news stories can spread very quickly.

In the worst cases, they can have major effects. There are suggestions that fake news influenced the 2016 US election. In another case, a gunman opened fire at a pizzeria that had been falsely but widely reported as being the centre of a paedophile ring involving prominent politicians. In less critical cases, fake news reports can result in distress or reputational damage for the people or organisations mentioned in the articles.

It is, therefore, important to be alert to the potential for reports to be fake, and to ensure that you are not party to their spread.

Spotting fake news

Unfortunately, it is not always easy to spot false news.

Sometimes, a story may be obviously false – for example, it may contain typos or spelling mistakes, or formatting errors. Like phishing emails, however, some fake news stories are a lot more subtle than that.

Facebook famously issued a guide to spotting fake news in May 2017. Its advice ranges from the obvious to the much less intuitive. Useful tips include:

Investigate the source

Be wary of stories written by unknown sources, and check their website for more information. Stories from reliable news sources, such as national newspapers or broadcasters, are more likely to have been checked and verified. It is also worth looking at the URL, to make sure it is a genuine news organisation.

Look at the evidence on which the article bases its claims, and check whether they seem credible. If there are no sources given, or the source is an unknown ‘expert’ or ‘friend’ of someone concerned, be sceptical.

Check whether other, reliable news sources are carrying the story

Sometimes, even otherwise reliable news sources get carried away and forget to do all the necessary checks. But one very good check is to ask whether other reliable sources are also carrying the story. If yes, it is likely to be correct. If not, you should at least be doubtful.

Facebook’s advice boils down to reading news stories critically.

That does not mean looking for their flaws, or criticising them, although this can be part of critical reading and thinking. Instead, it means applying logic and reason to your thinking and reading, so that you make a sensible judgement about what you are reading.

In practice, this means being alert to why the article has been written, and what the author wants you to feel, think or even do as a result of reading it. Even accurate stories may have been written in a way that is designed to steer you towards a particular point of view or action.

For more about this see our pages on Critical Thinking and Critical Reading .

A word about bias

It is worth remembering that everyone has their opinions, and therefore sources of potential bias in what they write. These may be conscious or unconscious. News organisations tend to have an organisational ‘view’ or political slant. For example, the UK’s Guardian is broadly left-wing, and most of the UK tabloids are right-wing in their views, and this affects both what they report and how they report it.

As a reader, you also have biases, both conscious and unconscious, and these affect the stories you choose to read, and the sources you use. It is therefore possible to self-select only stories that confirm your own view of the world, and social media is very good at helping with this.

To overcome this, it is important to use more than one source of information, and try to ensure that they have at least small differences in their political views.

A final thought

Fake news spreads so fast because we all like the idea of telling people something that they did not already know, something exclusive, and because we want to share our view of the world. It’s a bit like gossip.

But like false gossip, fake news can harm. Next time, before you click on ‘share’ or ‘retweet’, just take a moment to think about whether the story that you are spreading is likely to be true or not. Even if you think it is true, consider the possible effect of spreading it. Is it going to hurt anyone if it turns out to be false?

If so, don’t go there, think before you share.

Don’t Go Down the Rabbit Hole

Critical thinking, as we’re taught to do it, isn’t helping in the fight against misinformation.

By Charlie Warzel

Mr. Warzel is an Opinion writer at large.

For an academic, Michael Caulfield has an odd request: Stop overthinking what you see online.

Mr. Caulfield, a digital literacy expert at Washington State University Vancouver, knows all too well that at this very moment, more people are fighting for the opportunity to lie to you than at perhaps any other point in human history.

Misinformation rides the greased algorithmic rails of powerful social media platforms and travels at velocities and in volumes that make it nearly impossible to stop. That alone makes information warfare an unfair fight for the average internet user. But Mr. Caulfield argues that the deck is stacked even further against us. That the way we’re taught from a young age to evaluate and think critically about information is fundamentally flawed and out of step with the chaos of the current internet.

“We’re taught that, in order to protect ourselves from bad information, we need to deeply engage with the stuff that washes up in front of us,” Mr. Caulfield told me recently. He suggested that the dominant mode of media literacy (if kids get taught any at all) is that “you’ll get imperfect information and then use reasoning to fix that somehow. But in reality, that strategy can completely backfire.”

In other words: Resist the lure of rabbit holes, in part, by reimagining media literacy for the internet hellscape we occupy.

It’s often counterproductive to engage directly with content from an unknown source, and people can be led astray by false information. Influenced by the research of Sam Wineburg, a professor at Stanford, and Sarah McGrew, an assistant professor at the University of Maryland, Mr. Caulfield argued that the best way to learn about a source of information is to leave it and look elsewhere , a concept called lateral reading .

For instance, imagine you were to visit Stormfront, a white supremacist message board, to try to understand racist claims in order to debunk them. “Even if you see through the horrible rhetoric, at the end of the day you gave that place however many minutes of your time,” Mr. Caulfield said. “Even with good intentions, you run the risk of misunderstanding something, because Stormfront users are way better at propaganda than you. You won’t get less racist reading Stormfront critically, but you might be overloaded by information and overwhelmed.”

ORIGINAL RESEARCH article

“fake news” or real science critical thinking to assess information on covid-19.

Few people question the important role of critical thinking in students becoming active citizens; however, the way science is taught in schools continues to be more oriented toward “what to think” rather than “how to think.” Researchers understand critical thinking as a tool and a higher-order thinking skill necessary for being an active citizen when dealing with socio-scientific information and making decisions that affect human life, which the pandemic of COVID-19 provides many opportunities for. The outbreak of COVID-19 has been accompanied by what the World Health Organization (WHO) has described as a “massive infodemic.” Fake news covering all aspects of the pandemic spread rapidly through social media, creating confusion and disinformation. This paper reports on an empirical study carried out during the lockdown in Spain (March–May 2020) with a group of secondary students ( N = 20) engaged in diverse online activities that required them to practice critical thinking and argumentation for dealing with coronavirus information and disinformation. The main goal is to examine students’ competence at engaging in argumentation as critical assessment in this context. Discourse analysis allows for the exploration of the arguments and criteria applied by students to assess COVID-19 news headlines. The results show that participants were capable of identifying true and false headlines and assessing the credibility of headlines by appealing to different criteria, although most arguments were coded as needing only a basic epistemic level of assessment, and only a few appealed to the criterion of scientific procedure when assessing the headlines.

Introduction: Critical Thinking for Social Responsibility – An Urgent Need in the Covid-19 Pandemic

The COVID-19 pandemic is a global phenomenon that affects almost all spheres of our life, aside from its obvious direct impacts on human health and well-being. As mentioned by the UN Secretary General, in his call for solidarity, “We are facing a global health crisis unlike any in the 75-year history of the United Nations — one that is spreading human suffering, infecting the global economy and upending people’s lives.” (19 March 2020, Guterres, 2020 ). COVID-19 has revealed the vulnerability of global systems’ abilities to protect the environment, health and economy, making it urgent to provide a responsible response that involves collaboration between diverse social actors. For science education the pandemic has raised new and unthinkable challenges ( Dillon and Avraamidou, 2020 ; Jiménez-Aleixandre and Puig, 2021 ), which highlight the importance of critical thinking (CT) development in promoting responsible actions and responses to the coronavirus disease, which is the focus of this paper. Despite the general public’s respect of science and scientific advances, denial movements – such as the ones that reject the use of vaccines and advocate for alternative health therapies – are increasing during this period ( Dillon and Avraamidou, 2020 ). The rapid global spread of the coronavirus disease has been accompanied by what the World Health Organization (WHO) has described as the COVID-19 social media infodemic. The term infodemic refers to an overabundance of information (real or not) associated with a specific topic, whose growth can occur exponentially in a short period of time [ World Health Organization (WHO), 2020 ]. The case of the COVID-19 pandemic shows the crucial importance of socio-scientific instruction toward students’ development of critical thinking (CT) for citizenship.

Critical thinking is embedded within the framework of “21st century skills” and is considered one of the goals of education ( van Gelder, 2005 ). Despite its importance, there is not a clear consensus on how to better promote CT in science instruction, and teachers often find it unclear what CT means and requires from them in their teaching practice ( Vincent-Lacrin et al., 2019 ). CT is understood in this study as a set of skills and dispositions that enable students and people to take critical actions based on reasons and values, but also as independent thinking ( Jiménez-Aleixandre and Puig, 2021 ). It is also considered as a dialogic practice that students can enact and thereby become predisposed to practice ( Kuhn, 2019 ). We consider that CT has two fundamental roles in SSI instruction: one role linked to the promotion of rational arguments, cognitive skills and dispositions; and the other related to the idea of critical action and social activism, which is consistent with the characterization of CT provided by Jiménez-Aleixandre and Puig (2021) . Although research on SSIs has provided us with empirical evidence supporting the benefits of SSI instruction, particularly argumentation and students’ motivation toward learning science, there is still scarce knowledge on how CT is articulated in these contexts. One challenge with promoting CT, especially in SSIs, is linked to new forms of communication that generate a rapid increase of information and easy access to it ( Puig et al., 2020 ).

The study was developed in an unprecedented scenario, during the lockdown in Spain (March–May 2020), which forced the change of face-to-face teaching to virtual teaching, involving students in online activities that embraced the application of scientific notions related to COVID-19 and CT for assessing claims published in news headlines related to it. Previous studies have pointed out the benefits of virtual environments to foster CT among students, particularly asynchronous discussions that minimize social presence and favor all students expressing their own opinion ( Puig et al., 2020 ).

In this research, we aim to explore students’ ability to critically engage in the assessment of the credibility of COVID-19 claims during a moment in which fake news disseminated by social media was shared by the general public and disinformation on the virus was easier to access than real news.

Theoretical Framework

We will first discuss the crucial role of CT to address controversial issues and to fight against the rise of misinformation on COVID-19; and then turn attention to the role of argumentation in students’ development of CT in SSI instruction in epistemic education.

Critical Thinking on Socio-Scientific Instruction to Face the Rise of Disinformation

SSIs are compelling issues for the application of knowledge and processes contributing to the development of CT. They are multifaceted problems, as is the case of COVID-19, that involve informal reasoning and elements of critique where decisions present direct consequences to the well-being of human society and the environment ( Jiménez-Aleixandre and Puig, 2021 ). People need to balance subject matter knowledge, personal values, and societal norms when making decisions on SSIs ( Aikenhead, 1985 ) but they also have to be critical of the discourses that shape their own beliefs and practices to act responsibly ( Bencze et al., 2020 ). According to Duschl (2020) , science education should involve the creation of a dialogic discourse among members of a class that focuses on the teaching and learning of “how did we come to know?” and “why do we accept that knowledge over alternatives?” Studies on SSIs during the last decades have pointed out students’ difficulties in building arguments and making critical choices based on evidence ( Evagorou et al., 2012 ). However, literature also indicates that students find SSIs motivational for learning and increase their community involvement ( Eastwood et al., 2012 ; Evagorou, 2020 ), thus they are appropriate contexts for CT development. While research on content knowledge and different modes of reasoning on SSIs is extensive, the practice of CT is understudied in science instruction. Of particular interest in science education are SSIs that involve health controversies, since they include some of the challenges posed by the post-truth era, as the health crisis produced by coronavirus shows. The COVID-19 pandemic is affecting most countries and territories around the world, which is why it is considered the greatest challenge that humankind has faced since the 2nd World War ( Chakraborty and Maity, 2020 ). Issues like COVID-19 that affect society in multiple ways require literate citizens who are capable of making critical decisions and taking actions based on reasons. As the world responds to the COVID-19 pandemic, we face the challenge of an overabundance of information related to the virus. Some of this information may be false and potentially harmful [ World Health Organization (WHO), 2020 ]. In the context of growing disinformation related to the COVID-19 outbreak, EU institutions have worked to raise awareness of the dangers of disinformation and promoted the use of authoritative sources ( European Council of the European Union, 2020 ). Educators and science educators have been increasingly concerned with what can be done in science instruction to face the spread of misinformation and denial of well-established claims; helping students to identify what is true can be a hard task ( Barzilai and Chinn, 2020 ). As these authors suggest, diverse factors may shape what people perceive as true, such as the socio-cultural context in which people live, their personal experiences and their own judgments, that could be biased. We concur with these authors and Feinstein and Waddington (2020) , who argue that science education should not focus on achieving the knowledge, but rather on gaining appropriate scientific knowledge and skills, which in our view involves CT development. Furthermore, according to Sperber et al. (2010) , there are factors that affect the acceptance or rejection of a piece of information. These factors have to do either with the source of the information – “who to believe” – or with its content – “what to believe.” The pursuit of truth when dealing with SSIs can be facilitated by the social practices used to develop knowledge ( Duschl, 2020 ), such as argumentation understood as the evaluation of claims based on evidence, which is part of CT development.

We consider CT and argumentation as overlapping competencies in their contexts of practice; for instance, when assessing claims on COVID-19, as in this study. According to Sperber et al. (2010) , we now have almost no filters on information, and this requires a much more vigilant, knowledgeable reader. As these authors point out, individuals need to become aware of their own cognitive biases and how to avoid being victims themselves. If we want students to learn how to critically evaluate the information and claims they will encounter in social media outside the classroom, we need to engage them in the practice of argumentation and CT. This raises the question of what type of information is easier or harder for students to assess, especially when they are directly affected by the problem. In this paper we aim to explore this issue by exploring students’ arguments while assessing diverse claims on COVID-19. We think that students’ arguments reflect their ability to apply CT in this context, although this does not mean that CT skills always produce a well-reasoned argument ( Halpern, 1998 ). Students should be encouraged to express their own thoughts in SSI instruction, but also to support their views reasonably ( Puig and Ageitos, 2021 ). Specifically, when they must assess the validity of information that affects not only them as individuals but also the whole society and environment. CT may equip citizens to discard fake news and to use appropriate criteria to evaluate information. This requires the design and implementation of specific CT tasks, as this study presents.

Argumentation to Enhance Critical Thinking Development in Epistemic Education on SSIs

While the concept of CT has a long tradition and educators agree on its importance, there is a lack of agreement on what this notion involves ( Thomas and Lok, 2015 ). CT has been used with a wide range of meanings in theoretical literature ( Facione, 1990 ; Ennis, 2018 ). In 1990, The American Philosophical Association convened an authoritative panel of forty-six noted experts on CT to produce a definitive account of the concept, which was published in the Delphi Report ( Facione, 1990 ). The Delphi definition provides a list of skills and dispositions that can be useful and guide CT instruction. However, as Davies and Barnett (2015) point out, this Delphi definition does not include the phenomenon of action. We concur with these authors that CT education should involve students in “CT for action,” since decision making – a way of deciding on a course of action – is based on judgments derived from argumentation using CT. Drawing from Halpern (1998) , we also think that CT requires awareness of one’s own knowledge. CT requires, for instance, insight into what one knows and the extent and importance of what one does not know in order to assess socio-scientific news and its implications ( Puig and Ageitos, 2021 ).

Critical thinking and argumentation share core elements like rationality and reflection ( Andrews, 2015 ). Some researchers suggest understanding CT as a dialogic practice ( Kuhn, 2019 ) has implications in CT instruction and development. Argumentation on SSIs, particularly on health controversies, is receiving increasing attention in science education in the post-truth era, as the coronavirus pandemic and denial movements related to its origin, prevention, and treatment show. Science education should involve the creation of a dialogic discourse among members of a class that enable them to develop CT. One of the central features in argumentation is the development of epistemic criteria for knowledge evaluation ( Jiménez Aleixandre and Erduran, 2008 ), which is a necessary skill to be a critical thinker. We see the practice of CT as the articulation of cognitive skills through the practice of argumentation ( Giri and Paily, 2020 ).

This article argues that science education needs to explore learning experiences and ways of instruction that support CT by engaging learners in argumentation on SSIs. Despite CT being considered a seminal goal in education and the large body of research on CT supporting this ( Dominguez, 2018 ), debates still persist about the manner in which CT skills can be achieved through education ( Abrami et al., 2008 ). Niu et al. (2013) remark that educators have made a striking effort to foster CT among students, showing that the belief that CT can be taught and learned has spread and gained support. Therefore, CT has slowly made its way into general school education and specific instructional interventions. Problem-based learning is one of the most widely used learning approaches nowadays in CT instruction ( Dominguez, 2018 ) because it is motivating, challenging, and enjoyable ( Pithers and Soden, 2000 ; Niu et al., 2013 ). We see active learning methodologies and real-word problems such as SSIs as appropriate contexts for CT development.

The view that CT can be developed by engagement in argumentation practices plays a central role in this study, as Kuhn (2019) suggested. However, the post-truth condition poses some challenges to the evaluation of sources of information and scientific evidence disseminated by social media. According to Sinatra and Lombardi (2020) , the post-truth context raises the need for critical evaluation of online information about SSIs. Students need to be better prepared to assess science information they can easily find online from a variety of sources. Previous studies described by these authors emphasized the importance of source evaluation instruction to equip students toward this goal ( Bråten et al., 2019 ), however, this is not sufficient. Sinatra and Lombardi (2020) note that students should learn how to evaluate the connections between sources of information and knowledge claims. This requires, from our view, engaging students in CT and epistemic performance. If we want students to learn to think critically about the claims they will encounter on social media, they need to practice argumentation as critical evaluation.

We draw on research on epistemic education ( Chinn et al., 2018 ) which considers that learning science entails students’ participation in the science epistemic goals ( Kelly and Licona, 2018 ); in other words, placing scientific practices at the center of SSI instruction. Our study is framed in a broader research project that aims to embed CT in epistemic design and performance. In Chinn et al. (2018) AIR model, epistemic cognition has three core elements that represent the three letters of the acronym: epistemic Aims, goals related to inquiry; epistemic Ideals, standards and criteria used to evaluate epistemic products, such as explanations or arguments; and Reliable processes for attaining epistemic achievements. Of particular interest for our focus on CT is that the AIR model also proposes that epistemic cognition has a social nature, and it is situated. The purpose of epistemic education ( Barzilai and Chinn, 2017 ) should be to enable students to succeed in epistemic activities ( apt epistemic performance ), such as constructing and evaluating arguments, and to assess through meta-competence when success can be achieved. This paper attends to one aspect of epistemic performance proposed by Barzilai and Chinn (2017) , which is cognitive engagement in epistemic assessment. Epistemic assessment encompasses in our study the evaluation of the content of claims disseminated by media. Aligned with these authors we understand that this process requires cognitive and metacognitive competences. Thus, epistemic assessment needs adequate disciplinary knowledge, but also meta-cognitive competence for recognizing unsupported beliefs.

Goal and Research Questions

This paper examines students’ competence to engage in argumentation and CT in an online task that requires them to critically assess diverse information presented in media headlines on COVID-19. Competence in general can be defined as “a disposition to succeed with a certain aim” ( Sosa, 2015 , p. 43) and epistemic competence, as a special case of competence, is at its core a dispositional ability to discern the true from the false in a certain domain. For the purposes of this paper, the attention is on epistemic competence, being the research questions that drive the analysis of the following:

1. What is the competence of students to assess the credibility of COVID-19 information appearing in news headlines?

2. What is the level of epistemic assessment showed in students’ arguments according to the criteria appealed while assessing COVID-19 news headlines?

Materials and Methods

Context, participants, and design.

A teaching sequence about COVID-19 was designed at the beginning of the lockdown in Spain (Mid-March 2020) in response to the rise of misinformation about coronavirus on the internet and social media. The design process involved collaboration between the first and second author (researchers in science education) and the third author (a biology teacher in secondary education).

The participants are a group of twenty secondary students (14–15 years old), eleven of them girls, from a state public school located in a well-known seaside village in Galicia (Spain). They were mostly from middle-class families and within an average range of ability and academic achievement.

Students were from the same classroom and participated in previous online activities as part of their biology classes, taught by their biology teacher, who collaborated on previous studies on CT and learning science through epistemic practices on health controversies.

The activities were integrated in their biology curriculum and carried out when participants received instruction on the topics of health, infectious diseases, and the immune system.

Google Forms was used for the design and implementation of all activities included in the sequence. The reason to select Google Forms is that it is free and a well-known tool for online surveys. Besides, all students were familiar with its use before the lockdown and the teacher valued its usefulness for engaging them in online debates and in their own evaluation processes. This online resource provides anonymous results and statistics that the teacher could share with the students for debates. It needs to be highlighted that during the lockdown students did not have the same work conditions; particularly, quality and availability of access to the internet differed among them. Thus, all activities were asynchronous. They had 1 week to complete each task and the teacher could be consulted anytime if they had difficulties or any question regarding the activities.

The design was inspired by a previous one carried out by the authors when the first case of Ebola disease was introduced in Spain ( Puig et al., 2016 ), and follows a constructivist and scientific-based approach. The sequence began with an initial task, in which students were required to express their own views and knowledge on COVID-19 and health notions related with it, before then being progressively involved in the application of knowledge through the practice of modeling and argumentation. The third activity engaged them in critical evaluation of COVID-19 information. A more detailed description of the activities carried out in the different steps of the sequence is provided below.

Stage 1: General Knowledge on Health Notions Related to COVID-19

An individual Google Forms survey around some notions and health concepts that appear in social media during the lockdown, such as “pandemic”, “virus,” etc.

Stage 2: Previous Knowledge on Coronavirus Disease

This stage consisted of three parts: (2.1) Individual online survey on infectious diseases; (2.2) Introduction of knowledge about infectious diseases provided in the e-bugs project website 1 and activities; virtual visit to the exhibition “Outbreaks: epidemics in a connected world” available in the Natural History Museum website (blinded for review); (2.3) Building a poster with the chain of infection of the COVID-19 disease and some relevant information to consider in order to stop the spread of the disease.

Stage 3: COVID-19, Sources of Information

This stage consisted first of a virtual forum in which students shared their own habits when consulting scientific information, particularly coronavirus-related, and debated on the main media sources they used to consult for this purpose. Secondly, students had to analyze ten news headlines on COVID-19 disseminated by social media during the outbreaks; six corresponded to fake news and four were true. They were asked to critically assess them and distinguish which they thought were true, providing their arguments. Media sources were not provided until the end of the task, since the act of asking for the source was considered as part of the data analysis (see Table 1 ). The second part of this stage is the focus of our analysis.

Table 1. COVID-19 News Headlines provided to students.

Stage 4: Act and Raise Awareness on COVID-19

The sequence ended with the creation of a short video in which the students had to provide some tips to avoid the transmission of the virus. The information provided in the video must be supported and based on established scientific knowledge.

Data Corpus and Analysis

Data collection includes all individual surveys and activities developed in Google Forms. We analyzed students’ individual responses ( N = 28) presented in Stage 3. The research is designed as a qualitative study that utilizes the methods of discourse analysis in accordance with the data and the purpose of the study. Discourse analysis allows the analysis of the content (implicit or explicit) of written arguments produced by students, and so the examination of the research questions. Our analysis focuses on students’ arguments and criteria used to assess the credibility of COVID-19 headlines (ten headlines in total). It was carried out through an iterative process in which students’ responses were read and revised several times in order to develop an open-coded scheme that captures the arguments provided. To ensure the internal reliability of our codes, each student response was examined by the first and the second author separately and then contrasted and discussed until 100% agreement was achieved. The codes obtained were established according to the following criteria, summarized in Table 2 .

Table 2. Code scheme for research questions 1 and 2.

For Research Question 1, we distributed the arguments in two main categories: (1) Arguments that question the credibility of the information ; (2) Arguments that do not question the credibility of the information.

For Research Question 2, we classify arguments that question the credibility of the headline in accordance with the level of epistemic assessment into three levels (see Table 2 ). The level of epistemic assessment (basic, medium, and high) was established by the authors based on the criteria that students applied and expressed explicitly or implicitly in their arguments. These criteria emerged from the data, thus the categories were not pre-established; they were coded by the authors as the following: content (using the knowledge that each student has about the topic), source (questioning the origin of the information), evidence (appealing to empirical evidence as real live situations that students experienced), authority (justifying according to who supports or is behind the claim) and scientific procedure (drawing on the evolution of scientific knowledge).

Students’ Competence to Critically Assess the Credibility of COVID-19 Claims

In general, most students were able to distinguish fallacious from true headlines, which was an important step to assess their credibility. For those that were false, students were able to question their credibility, providing arguments against them. On the contrary, for true news headlines, as it was expected, most participants developed arguments supporting them. Thus, they did not question their content. In both cases, the arguments elaborated by students appealed to different criteria discussed in the next section of results.

As shown in Table 3 , 147 arguments were elaborated by students to question the false headlines; they created just 22 arguments to assess the true ones. This finding was expected by the authors, as arguments for questioning or criticality appear more frequently when the information presented differs from students’ opinions.

Table 3. Number of students who questioned or not each news headline on COVID-19.

Students showed a higher capacity for questioning those claims they considered false or fake news , which can be related to the need to justify properly why they consider them false and/or what should be said to counter them.

The headlines that were most controversial, meaning they created diverse positions among students, were these three: “The COVID-19 virus can be transmitted in areas with hot and humid climates,” “Skin manifestations (urticaria, chilblains, rashes…) could be among the mild symptoms of coronavirus” and “Antibiotics are effective in preventing and treating coronavirus infection.”

The first two were questioned by 11 students out of 28, despite being real headlines. According to students’ answers, they were not familiar with this information, e.g., “I think the heat is not good for the virus.” On the contrary, 17 students did not question these headlines, arguing for instance as this student did: “because it was shown that both in hot climates and in cold climates it is contagious in the same way.”

A similar situation happened with the third headline, which is false. A proportion of students (9 out of 28) accepted that antibiotics could help to treat COVID-19, showing in their answers some misunderstanding regarding the use of antibiotics and the diseases they could treat. The rest of the participants (19 out of 28) questioned this headline, affirming that “because antibiotics are used to treat bacterial infections and coronavirus is a virus,” among other justifications for why it was false.

Levels of Epistemic Assessment in Students’ Arguments on COVID-19 News Headlines

To analyze the level of epistemic assessment showed in students’ arguments when dealing with each headline, attention was focused on the criteria students applied (see Table 2 ). As Table 4 summarizes, almost all arguments included only one criterion (139 out of 169), and 28 out of 169 did not incorporate any criterion. These types of arguments can be interpreted as low epistemic assessment, or even without epistemic assessment if no criterion is included.

Table 4. Arguments used by students to assess the credibility of each COVID-19 headline.

In the category of Basic Epistemic Assessment , we include all students’ arguments that included one criterion: Content or Empirical Evidence. Students assessed the content of the claim appealing to their own knowledge about that piece of information or to empirical evidence, without posing critical questions for assessing the credibility of the source of information. These two criteria, content and evidence, were included in students’ arguments with a frequency of 86 and 23, respectively, with this category the most common (109 out of 169) when questioning false and true headlines. In the case of true headlines, arguments under this category were identified in relation to headlines 2 and 4, whose credibility were questioned by appealing to the content, such as: “those are not the symptoms (skin manifestations) ” . Examples of arguments assessing the content of false headlines are provided below:

“Because the virus is inside the body, and even if you injected alcohol into the body it would only cause intoxication”

This student rejects headline 5, appealing to the fact that alcohol causes intoxication rather than the elimination of coronavirus.

“I know a person who had coronavirus and they only gave him paracetamol”

In this example, the student rejects headline 6 and appeals to his/her own experience during the pandemic, particularly a close person who had coronavirus, as evidence against the use of antibiotics for coronavirus disease treatment.

The category Medium Epistemic Assessment gathers arguments that make critical questions, particularly those asking for information about the authority or the source of information. For us, these criteria reflect a higher level of epistemic performance since they imply questioning beyond the veracity of the headline itself to its sources and authorship. There are 20 out of 169 arguments coded within this category.

The assessment of true headlines includes arguments that question the authority and source, e.g., “because they said it on the news” (headline 2), “that news does not seem very reliable to me” (headline 4). It is also an ordinary category in questioning false headlines, since students appealed to the source (16), “because in the news they clarified that it was a fake news and because it is not credible either” (headline 10) or the authority (4), “because the professionals said they were more vulnerable (people over 70 years old) but not that it only affected them” (headline 7).

For the highest category, High Epistemic Assessment , we consider those arguments (12 out of 169) in which students appealed to the scientific procedure (11) to justify why the headline is false, which manifests students’ reliance on epistemic processes, e.g., “because treatments that protect against coronavirus are still being investigated” (headline 9). Also, under this category we include arguments that combined more than one criterion, content and scientific procedure “Because antibiotics don’t treat those kinds of infections. In addition, no medication has yet been discovered that can prevent the coronavirus” (headline 6). Students’ arguments included in this category were elaborated to assess false headlines.

Lastly, a special mention is afforded to those arguments that did not include any criteria (28), which are contained in the category Non-Epistemic Assessment. It appears more frequently in students’ answers to headlines 8 and 10, as these examples show: “I don’t think it’s true because it doesn’t make much sense to me” (headline 8) or “I never heard it and I doubt it’s true” (regarding drinking alcohol, headline 10).

The findings of our study indicate that students were able to deal with fake news , identifying it as such. They showed capacity to critically assess the content of these news headlines, considering their inconsistencies in relation to their prior knowledge ( Britt et al., 2019 ). As Evagorou (2020) pointed out, SSIs are appropriate contexts for CT development and to value the relevance of science in our lives.

The examination of RQ1 shows that a proportion of students were able to perceive the lack of evidence behind them or even identified that those statements contradict what science presents. This is a remarkable finding and an important skill to fight against attempts to diminish trust in science produced in the post-truth condition ( Dillon and Avraamidou, 2020 ). CT and argumentation are closely allied ( Andrews, 2015 ) but as the results show, knowledge domain seems to play an important role in assessing SSIs news and their implications. Specific CT requires some of the same skills as generalizable CT, but it is highly contextual and requires particular knowledge ( Jones, 2015 ).

Students’ prior knowledge influenced the critical evaluation of some of the COVID-19 headlines provided in the activity. This is particularly relevant in responses to headline 6 (false) “Antibiotics are effective in preventing and treating coronavirus infection.” A previous study on the interactions between the CT and knowledge domain on vaccination ( Ageitos and Puig, 2021 ) showed that there is a correspondence between them. This points to the importance of health literacy for CT development, although it would not be sufficient to provide students with adequate knowledge only, as judgment skills, in this case regarding the proper use of antibiotics, are also required.

We found that the level of epistemic assessment (RQ2) linked to students’ CT capacity is low. A big majority of arguments were situated in a basic epistemic assessment level, and just a few in a higher epistemic assessment. One reason that might explain these results could be related to the task design and format, in which students worked autonomously in a virtual environment. As CT studies in e-learning environments have reinforced ( Niu et al., 2013 ), cooperative or collaborative learning favors CT skills, particularly when students have to discuss and justify their arguments on real-life problems. The circumstances in which students had to work during the outbreak did not allow them to work together since internet connections were not good for all of them, so synchronous activities were not possible. This aspect is a limitation for this research.

There were differences in the use of criteria, and thus in the level of epistemic assessment, when students dealt with true and false headlines. This could be related to diverse factors, such as the language. The claims are marred by language and they are formulated in a different way. Particularly, it is quite nuanced in true statements while certain and resolute in false headlines. The practice of CT requires an understanding of the language, the content under evaluation and other cognitive skills ( Andrews, 2015 ).

In the case of false headlines, most arguments appealed to their content and less to the criteria of source, authority, and the scientific procedure, whereas in the case of true headlines most of them appealed to the authority and/or source. According to the AIR model ( Chinn and Rinehart, 2016 ), epistemic ideals are the criteria used to evaluate the epistemic products, such as claims. In the case of COVID-19 claims, students need to have an ideal of high source credibility ( Duncan et al., 2021 ). This means that students acknowledge that information should be gathered from reliable news media that themselves obtained information from reliable experts.

Only few students used the criterion of scientific procedure when assessing false headlines, which shows a high level of epistemic assessment. Promoting this type of assessment is important since online discourse in the post-truth era is affected by misinformation and by appeals to emotions and ideology.

Conclusion and Implications

This research has been conducted during a moment in which the lives of people were paralyzed, and citizens were forced to stay at home to stop the spread of the coronavirus disease. During the lockdown and even after, apart from these containment measures, citizens in Spain and in many countries had to deal with a huge amount of information about the coronavirus disease, some of it false. The outbreak of COVID-19 has been accompanied by dissemination of inaccurate information spread at high speed, making it more difficult for the public to identify verified facts and advice from trusted sources ( World Health Organization (WHO), 2020 ). As the world responds to the COVID-19 pandemic, many studies have been carried out to analyze the impact of the pandemic on the life of children from diverse views ( Cachón-Zagalaz et al., 2020 ), but not from the perspective of exploring students’ ability to engage in the epistemic assessment of information and disinformation on COVID-19 under a situation of social isolation. This is an unprecedented context in many aspects, where online learning replaced in-person teaching and science uncertainties were more visible than ever.

Participants engaged in the epistemic assessment of coronavirus headlines and were able to put into practice their CT, arguing why they considered them as true or false by appealing to different criteria. We are aware that our results have limitations. Once such limitation is that students performed the activity independently, without creating a collaborative virtual environment, understood by the authors as one of the e-learning strategies that better promote CT ( Puig et al., 2020 ). Furthermore, despite the fact that teachers were available for students to solve any questions regarding the task, the remote and asynchronous process did not allow them to guide the activity in a way that helped the students to carry out a deeper analysis. CT development and epistemic cognition depends on many factors, and teachers have an important role in achieving these goals ( Greene and Yu, 2016 ; Chinn et al., 2020 ).

The analysis of arguments allows us to identify some factors that are crucial and directly affect the critical evaluation of headlines. Some of the students did not question the use of antibiotics for coronavirus disease. This result highlights the importance of health literacy and its interdependency with CT development, as previous studies on vaccine controversies and CT show ( Puig and Ageitos, 2021 ). Although it is not the focus of this paper; the results point to the importance of making students aware of their knowledge limitations for critical assessment. A key instructional implication from this work is making e-learning activities more cooperative, as we have noted, and epistemically guided. Moreover, CT dimensions could be made explicit in instructional materials and assessments. If we want to prepare students to develop CT in order to face real/false news spread by social media, we need to engage them in deep epistemic assessment, namely in the critical analysis of the content, the source, procedures and evidence behind the claims, apart from other tasks. Promoting students’ awareness and vigilance regarding misinformation and disinformation online may also promote more careful and attentive information use ( Barzilai and Chinn, 2020 ), thus activities oriented toward these goals are necessary.

Our study reinforces the need to design more CT activities that guide students in the critical assessment of diverse aspects behind controversial news as a way to fight against the rise of disinformation and develop good knowledge when dealing with SSIs. Students’ epistemological views can influence their performance on argumentation thus, if uncertainty of knowledge is explicitly address in SSI instruction and epistemic activities, students’ epistemological views may be developed, and such development may in turn influence their argumentation competence and consequently their performance on CT.
