Types of misinformation or disinformation


a. Clickbait:  Stories deliberately fabricated to gain website visitors and increase advertising revenue for websites.  Use sensationalist headlines and the words shocking, amazing, unbelievable or you won’t believe what happened next. Can involve celebrities or mysterious stories.  May challenge your IQ or guess your personality type based on what you eat (drink, wear, your pets, etc.). 


b. Fabricated content is more interesting.  And deceiving.  According to Pew, about 1 in 4 reported sharing fabricated news, whether aware at the time or not.

Where to find reputable news sites:  An online tool

Best sites for news

The best news sites are those with high levels of truth and low levels of bias.  Newspapers, magazines and news sites which are Pulitzer Prize publications include Associated Press, Center for Public Integrity, Chicago Tribune, Reuters, The New York times, The New Yorker, the Wall Street Journal and Washington Post. 

News sites and online news magazines are less likely to have fake news, although they may be biased.  If a source is reliable, they will let you know their point of view.

To clearn things up, you can check your sources for truth and bias on the Media Bias/Fact Check site. (https://mediabiasfactcheck.com/)  This site analyzes websites, using a rating system to determine media and truth.

Media Bias/Fact Check

View Interactive chart which outlines facts and bias on a number of publications.  Note that results are found by taking one story and evaluating it.  As a result, some ratings may change periodically.  Click here for an interactive view of this chart.

After going to the site online, look at some of your trusted news sources.  Are you surprised?

Tips to tell if information is correct:  

•     Check the source:  Do you recognize the website, is the source reliable, can you find more about the author?

•     Go beyond the headline:  Read the entire story, as sometimes they use sensational headings to grab attention.  Be wary of headlines in all caps and using exclamation points.  Look at the quotes.  Are they from professionals (academics, experts)?  Double check their credentials using Google search

•     Check other sources:  Is anyone else reporting on this?  Are there sources in the story?  Are they reliable?  Do they even exist?

•     Check the facts:  Check when article was published; is it current, or an old news story?

•     Check your own biases:  Are your own views and beliefs affecting your opinion of a news feature or report?  The source mentioned above (Media Bias/Fact Check) can help guide your understanding.

•     Check the website:  Many people have trouble recognizing sites that are satire.  Satire sites include The Onion and ClickHole. Check the About Us section, which should tell you about the company that runs it, the members and mission statement.

You can also use this tool to determine the validity of the information.

Deep Fakes and the upcoming election

The landscape has changed in recent years, reflecting a combination of real and fake videos and images.  While in the past, it may have been easier to spot fake media, this has become much more challenging with AI.  And if you have difficulty spotting AI deep fakes, don't feel bad.  Research has suggested that nearly 2/3 of people can't tell the difference between AI-generated images and voices.  So what can you do?  Here are some practical tools to help you decipher what is real and what is not:

Viral posts on social media:  You would think that if a post is shared by millions of people, it must be true.  Unfortunately, this is not the case.  There are automated accounts which are creating and spreading misinformation to lead public opinion.  It is virtually impossible to identify all of them.  So, before sharing something on social media, look deeply into the source.  If you can't verify it is authentic, do not repost.

Look for other coverage:  Perhaps the scammer has put together a convincing image or video.  But they cannot fake the context.  So if you hear something which is outlandish or far fetched, look for other sources.  If you are unsuccessful, then double check with resources such as Google Fact Check Explorer, Verify this or Snopes.  

Reverse image search:   If there is a picture on a potentially fake news site, do a reverse image search.  Use Google image to help.  To access Google Image search, go to www.google.com/images.  Click on the little camera icon on the right of the search bar, next to the microphone. You will be prompted either to enter the URL of a photo you've found online or to upload a photo from your computer. Then your results will appear. Often you'll be able to get additional information about when and where the photo first appeared, along with the people who appear in the photo, if they're well-known.  OR, try TinEye, which can be used as a browser attachment for a quick search.

Another excellent video outlines the effects of deep fake video and voice.  

Spotting AI in video and images

AI has made it very difficult to spot deep fakes.  However, if you pay attention to details, you may have some helpful ways to help you determine if what you are seeing is actually real.

Criteria for spotting deep fakes:

A research project at MIT came up with a list of criteria for spotting deep fakes.  It includes:

Practice spotting deep fakes:

Northwestern University has set up a site with over 600 images where you can indicate if an image is real or fake.  They will use your results to determine how often people can figure out what is real.  If you don't want to go through them all, go through several to see how you do.

Fact checking sites 

There are a number of ways that you can check the accuracy on a site.  Some options: 

Testing yourself

Game:  Cranky Uncle is a fun but challenging game that helps us to understand the techniques used to mislead.  It is useful in helping us to point out the fallacies of what we learn. 

Game:  Bad News is a game where you are the one posting misinformation.  You are led through techniques that are used to spread misinformation and the ways that they achieve this.  

Game:  Spot the troll is unlike the others in that it uses real social media accounts.  A troll is Internet slang for a person who intentionally tries to instigate conflict, hostility, or arguments in an online social community. Platforms targeted by trolls can include the comment sections of YouTube, forums, or chat rooms.  Trolls often use inflammatory messages to provoke emotional responses out of people, disrupting otherwise civil discussion. Trolling can occur anywhere that has an open area where people can freely post their thoughts and opinions.  Unfortunately, some trolls are not who they seem to be.  In this game, you identify which are real people and which are not.
