How Journalists and Social Media Users Perceive Online Fact

How Journalists and Social Media Users Perceive Online Fact

While services for fact-checking and verification to counter fake news in social media have increased, little research has investigated how journalists and the public perceive such services. This study reflects the outcomes of REVEAL, a three-year European Union research project investigating the use and impact of services for fact-checking and verification. Based on interviews with 32 young journalists and content analysis of social media users’ online conversations, we contribute new knowledge about the ways that journalists and social media users perceive online fact-checking and verification services. The findings suggest that, while young journalists were largely unfamiliar with or ambivalent about such services, they judged them as potentially useful in the investigative journalistic process. Yet, they were unwilling to rely exclusively on these tools for fact-checking and verification. A comparison of journalists’ perceptions with those of social media users reveals social media users are similarly ambivalent. Some accentuated the usefulness of such services, while others expressed strong distrust. However, the journalists displayed a more nuanced perspective, both seeing these services as potentially useful and being reluctant to blindly trust a single service. Design strategies to make online fact-checking and verification services more useful and trustworthy are suggested.


The joint first authors, Brandtzaeg and Følstad, contributed equally to this work. We would like to thank our colleagues in the REVEAL project and all the journalists attending the interviews.

Tools That Fight Disinformation Online

RAND researchers developed a searchable online database that provides information about tools that fight online disinformation, particularly on social media.

Tools That Fight Disinformation Online

Adblock Plus is a browser extension and app that blocks advertisements and websites through the use of filtering lists. The tool automatically whitelists ads that meet the “acceptable ads” standards — so ads can avoid being blocked on this platform by adhering to those standards. Users can opt out of even these ads by adjusting the default settings. The tool, while initially an adblocker, has increasingly seen itself as a way for users to protect themselves not only from harmful ads, but also from other harmful sites, including those that spread disinformation.

This tool intended to build user understanding of the techniques involved in the dissemination of disinformation. This game exposes players to fake news tactics used against them by putting them in the position of a news baron for fake news. Players win by publishing headlines that attract the most followers.

Bot Sentinel is a free platform developed to detect and track trollbots and untrustworthy Twitter accounts. Bot Sentinel uses machine learning and artificial intelligence to study Twitter accounts, to classify them as trustworthy or untrustworthy, and to identify bots. It then stores those accounts in a database to track each account daily. Developers use the data they collect to explore the effect of bots and their propaganda on discourse and to explore ways to counter the spread of bots and the information they disseminate. Classifying untrustworthy accounts is a manual process. They review hundreds of tweets and retweets during the review process. If an account has a large number of followers and a high percentage of misleading and/or factually incorrect tweets, they might classify that account as untrustworthy.

Botometer is a web-based program that uses machine learning to classify Twitter accounts as bot or human by looking at features of a profile including friends, social network structure, temporal activity, language and sentiment.

How is the fact

Salud con lupa designed a methodology to fact-check health issues.

How is the fact

The COVID-19 pandemic has revealed one unquestionable truth: information is power. But we need to ask ourselves: What type of information? Recently, fake news and misrepresented scientific data have caused as much, or perhaps even more, damage than the coronavirus itself. Thinking about health, people form habits based on the news they consume, believe and share, and those habits impact their well-being. That is why this section of our website, called “Comprueba” (or “Verify” in English) offers our readers a variety of relevant health news stories, all based on rigorously verified information. While scientists work to find the cure for the coronavirus, the rest of us can learn how to keep ourselves well-informed, a habit we need to continue forming every day.

Reliable sources are the foundation of everything we do, and our “Verify” section combines the strengths of journalism and science. For all the articles in this section of our site, our journalists at Salud Con Lupa work in collaboration with scientists from the Epistemonikos Foundation, a Chilean nonprofit specialized in the systematic review of scientific information related to health. The Epistemonikos Foundation is supported by a community of science experts and also has a collaborative, multilingual database of health evidence comprised of more than 100,000 studies. The health and science information provided by the Epistemonikos Foundation helps us detect lies being circulated about public health and determine which topics we should be investigating.

The content we create for “Verify” can be broken down into two categories: explainers and fact-checks. An explainer is an article that allows readers to clearly understand scientific facts. Sometimes, in their quest to simplify science data, media organizations end up misrepresenting the original information. Our explainers will show our readers the bigger picture related to a specific topic and clearly state the scientific evidence related to that topic. The goal with these explainers is to provide our readers the essential information they need to make responsible decisions. Here is one of our explainers about the coronavirus (in Spanish): You Can Open Your Windows, The Coronavirus Isn’t An Invisible Cloud In The Air

A fact-check, on the other hand, is an article with a more specific purpose – to prove if something is true or false. By nature, it isn’t always possible to come up with a straightforward answer to this question. Acknowleding this reality, for our verifications we will review all available scientific evidence to provide readers with fact-checks well supported by scientific information. As an example, here is one of our fact-checks (in Spanish): There Is Not Evidence To Support That Two Malaria Medications Work To Treat COVID-19

For both our explainers and fact-checks, we will provide links to the sources we analyzed so that our readers can look further into any given topic themselves.

Health information is perhaps the information with the most direct impact on our lives; based on what we know about health, many of us decide what to eat, what medications we want to trust and what healthcare treatments we want to choose. That is why it is crucial that we make those decisions with information that is “healthy” too, free from lies and manipulation.

The “Verify” section of our site will also feature a project called the Lupa Colectiva (or “the Magnifying Glass Collective”, in English). With this project we will create a community of specialized, Spanish-language fact-checkers. Soon, we will launch a virtual whiteboard where journalists, scientists, health professionals and citizen contributors who are interested in rigorous fact-checking can share the information they review. They will also be able to propose topics for further verification.

We do not intend for Salud Con Lupa to become a source for medical advice. We understand that everyone has a unique medical history and it is critical that everyone seeks guidance from doctors and other medical professionals. Our goal with Salud Con Lupa is to discredit false claims about public health, which are all over the internet, and provide rigorously verified information. The health topics we decide to fact-check will be determined both directly and indirectly by input from our Spanish-speaking readers.

Salud Con Lupa is part of the #CoronaVirusFacts/ #DatosCoronaVirus Alliance created by the Poynter Institute’s International Fact-Checking Network. More than 100 fact-checking organizations worldwide are part of this initiative, working to fight misinformation related to the COVID-19 pandemic. Salud Con Lupa is also a part of the LatamChequea (Latin American Fact-Checking) Network, a collaborative initiative designed to provide verified, clear information to the public.
