The last few years there has been a rapid rise in the amount of fake news that is shared online, especially on Twitter (McGonagle, 2017; Lazer et al., 2018). This can be seen as a serious issue, since fake news can manipulate the public’s perception of reality and change attitudes (Damico, 2019). With the rise of the COVID-19 pandemic, it is of importance that the public is informed with accurate information (Hou et al., 2020). However, the amount of fake news that is spread about the coronavirus has increased (Apuke & Omar, 2020). This is problematic, since it can endanger public health (Europol, 2020; Waszak et al., 2018). Therefore, we investigated whether tweets about COVID-19 contain accurate information.
Information overload and digital images
The last few years, there has been a rapid rise in number of posts that are shared online. Social media users receive an endless flow of information. This can lead to an information overload, which has become a major problem in modern society (Zhang, Ding & Ma, 2020). “Information overload occurs when the amount of input to a system exceeds its processing capacity” (Toffler, 1984, p. 21). In order to gain attention from users, content needs to stand in some way. Almost 3.2 billion digital images are shared every day (Meeker, 2016). Multiple studies state that adding images or videos to a social media post help to stand out from text-only posts. In addition, the presence of a photo in a tweet will increase the amount of likes and number of retweets (Li & Xie, 2020). For example, a tweet containing a photo gets 18% more clicks, 89% more likes, and 150% more retweets than those without a photo (Cao et al., 2020). In addition, visualizations may help consumers with processing the content a lot easier (Cook & Lewandosky, 2011).
Images and retweets enhance credibility
Information that contains photos is perceived as more credible. This is because people often believe that photos provide evidence of an event being occurred, even though it might provide a false claim (Kelly & Nace, 1994; McCabe & Castel, 2008). Unfortunately, this advantage is also taken by fake news. Fake news usually contains misrepresented or tampered images, or videos to attract and mislead consumers (Cao et al., 2020). In addition, users asses the credibility of tweets by looking at the number of retweets. According to Morris et al. (2012), a high number of retweets increases the perceived credibility. Consequently, tweets that contain photos, even tampered ones, will receive more retweets whereas these retweets are used as a measure to asses credibility. In the context of fake news, this is worrisome since people asses credibility by the number of retweets, and not by the accuracy of provided information. Therefore, we investigated to what extent the visuals (i.e., images and videos) in COVID-19’s most retweeted tweets are credible.
Fact-checking
During the pandemic, a lot of tweets were posted about the Corona virus in the Netherlands. On the basis of a file containing COVID-19 related tweets by Pointer, we first draw a sample of the most retweeted tweets that contained visuals. Second, we analysed and evaluated each visual on their credibility. We aimed to find the original source of the each visual. To do this, we used Google reverse image search, TinEye, and Wolframalpha. In the case of a video, we fact-checked it by means of Google. If needed, screenshots of the video were put through image reverse search engines.
Fact-checked tweets results
In Figure 1, an overview is given of the results (i.e., true, mostly true, half true, false, mostly false or no evidence) of the analysed tweets. The results show that more than half of the fact-checked tweets are true (60%), which is striking because we did not expect that due to the amount of fake-news that is spread nowadays (McGonagle, 2017). The number of tweets that were mostly true, half true, mostly false and false were almost evenly distributed with an average of 9.1%. In addition, a small part of the tweets had no evidence (3.0%), which means that the tweets couldn’t get linked to confirming or contradicting evidence.
Tweets that were true
As earlier stated, 60% of the fact-checked tweets appeared to be true, which means that the photo or video was related to the context of the tweet, and there was nothing significant missing. An example of a reliable photo that is used in a tweet is shown in Figure 2. We labelled it as true, since the source of this picture (Rijksoverheid) is credible, the photo provides accurate information (e.g., the date of both the picture and the tweet corresponded), and it was tweeted by the Dutch Prime Minister, which makes perfectly sense.
Tweets that were mostly true
8% of the tweets we fact-checked were mostly true, which indicates that the photo or video of the tweet was accurate but needs some clarification or additional information. An example of such tweet is a from Wilders (2020), which can be seen in Figure 3. The photo, added to the Tweet, mentioned a motion and the outcome of the motion. However, it did not show the arguments that other parties had given, neither further explanations were shown.
Tweets that are mostly false
11% of the fact-checked tweets were mostly false, because the visuals within the tweets contained elements of truth but ignored critical facts that would have given a different context. For example, in a video of a tweet from Wilders (2020), which is shown in Figure 5, he states that Minister de Jonge gives no information about how many intensive care beds will be available. However, in a debate Minister de Jonge did say that there will be 1600 IC beds and that this will be enough to cover the care. So, the statement in this video is mostly false, since Minister de Jonge did give this information. However, the video of Wilders does not show this statement of minister de Jonge.

So, the statement in this video is mostly false, since Minister de Jonge did give this information. However, the video of Wilders does not show this statement of minister de Jonge.
Tweets that were false
9% of the fact-checked tweets were false, because the content of the visual was not accurate. For example, a tweet of Lavie Jan Roos (2020) is labelled as false, since the photo visualized how political parties voted for the motion of Baudet. As can be seen in Figure 6, the data in the picture says that political party ‘50PLUS’ voted in favour. However, according to Tweede Kamer.nl, they voted against the motion (Tweede Kamer.nl, 2020). In addition, the use of photoshop has been also found regularly, which makes the tweet automatically false.
Tweets that had no evidence
3% of the fact-checked tweets were labelled as no evidence, because they could not be linked to confirming or contradicting evidence. An example of such a non-fact-checkable video is shown in Figure 7. In the tweet, someone claims that she is arrested and that her head was beaten against the wall by the police. However, there was no evidence found that this person in the video is the person who makes these claims in the tweet itself.
Are the most retweeted tweets, that contain visuals, about COVID-19 reliable?
Fortunately, our results showed that the major part of the analysed tweets turned out to be true information (60%), and therefore cannot be labelled as misinformation. However, the other 40% of the analysed tweets contained visuals that are either mostly true, half true, false, mostly false or had no evidence. This raises concern, since fake news can manipulate the public’s perception of reality and is able to change attitudes (Damico, 2019). Especially news and information spread concerning the COVID-19 virus should be reliable and accurate. That this is not fully the case is alarming. Mainly, because visuals shared in a post receive more likes, clicks and retweets and are perceived as credible storytelling (Cao et al., 2020) (Morris et al., 2020). As a result, this could go viral and lead to a digital wildfire (Lewandosky et al., 2017).
With this article, we hope to make the public aware of the fact that not all the information about COVID-19, shared on Twitter, is accurate. Always be critical and cautious with the information that comes across. It’s crucial to fact-check information, before we decide what we believe or what is true or false. Especially when it has such a large impact on our lives, as the COVID-19 pandemic.
