Q1. Which of the following best describes misinformation?
  • A. Information that is deliberately created to deceive people for political gain
  • B. False or inaccurate information shared without the intent to deceive ✓
  • C. Any opinion that differs from the majority view of experts
  • D. Information that has been removed from a social media platform

Why: Misinformation is false or inaccurate information spread without necessarily intending to mislead. Deliberately deceptive content is better classified as disinformation, and opinions or removed content are not defined by falsity.

Q2. What is the main difference between misinformation and disinformation?
  • A. Misinformation is always spread by bots, while disinformation is spread by humans
  • B. Misinformation is false but shared without intent to deceive, while disinformation is false and deliberately spread to mislead ✓
  • C. Misinformation appears only on social media, while disinformation appears in news outlets
  • D. Misinformation is always true in part, while disinformation is entirely fabricated

Why: The key distinction is intent. Misinformation is false content shared without intent to deceive, such as a person sharing a fake news story they believed was real. Disinformation is false content created or shared with the deliberate aim of misleading.

Q3. Which psychological tendency makes people more likely to believe and share information that confirms what they already think?
  • A. Availability heuristic
  • B. Confirmation bias ✓
  • C. Bandwagon effect
  • D. Dunning-Kruger effect

Why: Confirmation bias is the tendency to seek out, interpret, and remember information that supports existing beliefs. It makes confirming content feel more credible and more worth sharing, which helps misinformation spread within like-minded groups.

Q4. Why does emotionally charged content, such as content that provokes anger or fear, tend to spread faster online?
  • A. Emotional content is always more accurate than neutral content
  • B. Platform algorithms and human psychology both tend to reward strong emotional reactions with more engagement and sharing ✓
  • C. Emotional content is automatically flagged as true by fact-checkers
  • D. Governments require emotional content to be promoted more heavily

Why: Strong emotions like outrage and fear prompt quick reactions, and people are more likely to share content that stirs them. Engagement-driven algorithms then amplify content that gets many reactions, regardless of whether it is accurate.

Q5. Which of the following is a good habit to reduce the spread of misinformation before sharing a post?
  • A. Sharing quickly so your followers see it first
  • B. Trusting content more if it has many likes or shares
  • C. Checking the source and looking for corroboration from reliable outlets before sharing ✓
  • D. Assuming a post is true if a friend shared it

Why: Verifying the original source and checking whether reliable outlets report the same information helps catch false content. Likes, shares, and recommendations from friends do not indicate accuracy, since misinformation often spreads widely through those very signals.

Q1. What is the main purpose of a recommendation algorithm on a social media platform?
  • A. To verify whether posts are factually accurate
  • B. To predict and show content that will keep a user engaged ✓
  • C. To delete posts that break platform rules
  • D. To send every user the same chronological feed of posts

Why: Recommendation algorithms are designed to predict what content a user is likely to engage with (clicks, likes, watch time, shares) and prioritize it, which helps keep the user on the platform. They are not primarily designed to verify accuracy or to show identical feeds.

Q2. Why can engagement-based ranking sometimes help misinformation spread?
  • A. Misinformation is always labeled, so algorithms avoid it
  • B. Content that provokes strong emotions like surprise or anger often gets more engagement, regardless of whether it is true ✓
  • C. Algorithms only recommend content from verified government sources
  • D. False posts are automatically shown to fewer people than true posts

Why: Because algorithms reward engagement, emotionally charged or sensational content tends to get more clicks and shares. Accuracy is not a built-in ranking signal, so false but provocative content can outperform accurate, less exciting content.

Q3. What is a 'filter bubble'?
  • A. A security tool that blocks all external websites
  • B. A situation where personalized algorithms mostly show users content that matches their existing views ✓
  • C. A type of fake account used to spread advertisements
  • D. A method of compressing videos to load faster

Why: A filter bubble describes the isolation that can occur when personalization repeatedly shows users content aligned with their past behavior and beliefs, reducing their exposure to differing perspectives and making misinformation within the bubble seem more widely believed.

Q4. Which of the following is a good habit when you notice a post that seems designed to make you angry or shocked?
  • A. Share it immediately so others can see it
  • B. Pause and check the source and whether other reliable outlets report the same claim ✓
  • C. Comment with insults to correct the person who posted it
  • D. Assume it is true because the algorithm showed it to you

Why: Emotionally charged content is a common vehicle for misinformation. Pausing, checking the original source, and looking for corroboration from reliable outlets helps you avoid amplifying false claims. Being shown something by an algorithm is not evidence that it is accurate.

Q5. What does it mean that an algorithm 'personalizes' your feed?
  • A. It shows every user exactly the same posts in the same order
  • B. It uses data about your past behavior, such as likes and watch history, to tailor what you see ✓
  • C. It asks you to write your own posts before you can see others'
  • D. It removes all advertisements from your feed

Why: Personalization means the platform uses signals from your past activity, like what you liked, watched, or lingered on, to choose what appears in your feed. This is why two people can see very different content on the same platform.

Q1. Which of the following is a common sign that a post is trying to manipulate your emotions rather than inform you?
  • A. It cites specific, verifiable sources with links
  • B. It uses extreme language like 'outrageous' or 'you won't believe this' to provoke a strong reaction ✓
  • C. It presents data with clearly stated limitations
  • D. It acknowledges uncertainty about the facts

Why: Emotionally manipulative content often relies on loaded or sensational language designed to trigger anger, fear, or excitement before you have time to think critically. Accurate reporting usually describes events plainly and invites evaluation rather than demanding an immediate emotional response.

Q2. What is 'fear appeal' in the context of misinformation?
  • A. Presenting a balanced view of both risks and benefits of a policy
  • B. Warning of a dire threat, often exaggerated, to push people toward a particular belief or action ✓
  • C. Encouraging readers to verify claims before sharing them
  • D. Explaining how to protect yourself from scams using official guidance

Why: Fear appeals exaggerate or invent dangers to make people feel threatened, which can short-circuit careful judgment and make them more willing to accept a claim or share it quickly. Recognizing a fear appeal means asking whether the threat is proportionate and supported by evidence.

Q3. Why do emotionally charged posts tend to spread faster online?
  • A. Platforms are legally required to promote emotional content
  • B. Strong emotions like anger and outrage motivate people to react, comment, and share without verifying ✓
  • C. Emotional posts are always factually accurate
  • D. Calm posts are automatically hidden by algorithms

Why: High-arousal emotions such as anger and anxiety increase the likelihood that people engage and pass content along. Because engagement signals often drive visibility, emotionally provocative content can spread widely regardless of whether it is true.

Q4. A post says: 'They don't want you to know this, so share before it gets deleted!' Which manipulation tactic is being used?
  • A. Peer-reviewed citation
  • B. Appeal to a fabricated conspiracy combined with urgency ✓
  • C. Neutral fact-checking
  • D. Transparent disclosure of methods

Why: The message pairs a claim of hidden secret knowledge (a conspiracy framing) with time pressure ('before it gets deleted'). Both features are designed to make you act quickly and feel special for sharing, rather than pausing to check the claim.

Q5. Which response is the best first step when you notice a post making you feel intensely angry or scared?
  • A. Share it immediately so your friends can react too
  • B. Pause, notice the emotional reaction, and check the claim against reliable sources before sharing ✓
  • C. Comment with the most inflammatory response you can think of
  • D. Assume it is true because it matches your existing beliefs

Why: Simply noticing a strong emotional reaction is a useful signal to slow down. Pausing and verifying with reliable sources gives your rational judgment a chance to catch up before you spread or respond to potentially manipulative content.

Q1. Which of the following is the most useful first step when you encounter an unfamiliar news website making a surprising claim?
  • A. Share the article quickly so your friends can see it before it disappears
  • B. Check who runs the site and whether established, reputable outlets report the same claim ✓
  • C. Assume it is true because the headline uses specific numbers and quotes
  • D. Trust the site if its design looks professional and modern

Why: Lateral reading, checking what others say about a source, is a core evaluation skill. Professional design and specific details can be easily faked, so verifying the source's reputation and corroboration from independent outlets is the most reliable first step.

Q2. What does it mean to 'read laterally' when evaluating online information?
  • A. Reading the article from left to right while scanning for typos
  • B. Leaving the original page to open other sources that reveal who is behind a claim and how reliable they are ✓
  • C. Reading only the comments section beside the main article
  • D. Skipping to the end of an article to see its conclusion first

Why: Lateral reading means moving away from a page to investigate it using other sources. Professional fact-checkers use this approach because a site's own 'About' page can be misleading, while independent sources give a more accurate picture.

Q3. A study is cited in a viral post as proof of a health benefit. Which factor most directly indicates the evidence may be weak?
  • A. The study was published in a peer-reviewed journal
  • B. The study was conducted on a very small sample and has not been replicated ✓
  • C. The study has been cited by several other researchers
  • D. The study's authors are affiliated with a university

Why: Small sample sizes and lack of replication are major warning signs that a finding may not hold up. Peer review, citations, and university affiliation are generally positive signals, though none guarantees accuracy on their own.

Q4. Why is a claim that appears in many places online not necessarily more credible?
  • A. Repetition always indicates the claim has been disproven
  • B. Online content can be copied, shared, and amplified without any independent verification, so repetition may reflect spread rather than evidence ✓
  • C. Search engines only show false information
  • D. Claims that appear often are always written by experts

Why: Information can circulate widely through sharing and algorithms without ever being checked. Many copies of a claim may all trace back to one unreliable original, so counting repetitions does not measure truth.

Q5. Which question is most important to ask when assessing whether a photo accompanying a news story is authentic?
  • A. Is the photo in color or black and white?
  • B. Does the photo's original source and date match the event described, and can you find where it first appeared? ✓
  • C. Is the photo high resolution?
  • D. Does the photo make me feel angry or sad?

Why: Images are often reused out of context, with old photos presented as recent events. A reverse image search and checking the original source and date help confirm whether the image actually matches the claimed event.

  • B. The video may have been edited or manipulated, and you should verify it with reliable sources
  • C. The video is definitely authentic because it was recorded in a professional setting
  • D. The audio was added by the platform to improve viewer engagement
Q4. Which of these is an example of 'cheapfakes' or 'shallowfakes' rather than AI-generated deepfakes?

  • C. A face swap generated by a neural network
  • D. A fully computer-generated image of a person who does not exist
Q5. Why is it important to check the original source of a video before sharing it?
  • A. Original sources always have higher video resolution
  • B. Videos are often reposted out of context, and the original source can show the date, location, and full situation
  • C. Platforms require source verification before any video can be shared
  • D. Original uploaders are legally required to label all edits they make

Q1. Which of the following is a common sign that an online account may be a bot rather than a real person?
  • A. It posts detailed personal stories about its daily life over several years
  • B. It posts at extremely high frequency, around the clock, with little variation in content
  • C. It has a profile photo and a bio describing its hobbies
  • D. It replies to comments on its posts in a conversational tone
Q2. What is a 'coordinated inauthentic behavior' campaign?
  • A. A group of people who independently share the same opinion on a public issue
  • B. A deliberate effort by networks of accounts, often hidden in their origin, to manipulate public discussion while appearing to be unconnected users
  • C. A fact-checking organization collaborating with social media platforms
  • D. A viral trend that spreads naturally because many users find the content entertaining
Q3. Why do fake accounts often use stolen or AI-generated profile photos?
  • A. Platforms require all profile photos to be professionally produced
  • B. It makes the account look more trustworthy and harder to trace back to a real identity
  • C. Profile photos are needed to access advertising tools
  • D. Stolen photos load faster on mobile devices
Q4. Which practice is a useful step when you suspect a cluster of accounts is part of a coordinated campaign?
  • A. Immediately reposting the content to warn your followers before checking anything
  • B. Checking whether the accounts were created recently, posting nearly identical messages, and following or amplifying each other in a tight network
  • C. Assuming the accounts are real because they have many followers
  • D. Reporting only the single account with the most posts and ignoring the rest
Q5. Why can a large number of accounts posting the same message be misleading about public opinion?
  • A. Platforms always hide duplicate posts from other users
  • B. Repetition from a small set of coordinated or fake accounts can create the false impression that many independent people hold a view
  • C. Identical posts are automatically flagged as spam and removed, so they reflect majority support
  • D. Only real people are able to post identical messages

Q1. Before sharing a surprising news headline, what is the most useful first step?
  • A. Share it quickly so your friends see it first
  • B. Check whether other reliable sources report the same story ✓
  • C. Add a caption saying you're not sure it's true
  • D. Wait for someone else to share it before you do

Why: Confirming a claim with multiple independent, reliable sources is one of the simplest ways to catch false or misleading stories before they spread.

Q2. Which detail is the strongest sign that a website may not be a trustworthy news source?
  • A. It uses a simple, clean design
  • B. It has no author, contact information, or clear editorial policy ✓
  • C. It publishes stories every day
  • D. It includes photos in its articles

Why: Reliable outlets usually identify their authors, provide contact details, and explain how they correct errors. A lack of these is a common warning sign of unreliable sites.

Q3. A post shows a photo with the caption 'Breaking: this happened today.' What should you check first?
  • A. Whether the photo is attractive enough to share
  • B. Whether the image has appeared online before with a different date or location ✓
  • C. How many likes the post has received
  • D. Whether the caption uses capital letters

Why: Old or out-of-context images are often recirculated as if they are recent. A reverse image search can reveal whether the photo is actually from a different time or place.

Q4. Why is it a good habit to pause before sharing content that makes you feel angry or afraid?
  • A. Strong emotions make content more likely to be accurate
  • B. Emotional content is often designed to spread quickly, and strong feelings can reduce careful thinking ✓
  • C. Platforms require a pause for emotional posts
  • D. Emotional posts are always fake

Why: Misinformation often relies on triggering strong emotions because they encourage immediate sharing. Pausing gives you time to evaluate the claim rather than react to it.

Q5. What is a responsible way to share a post you later realize was false?
  • A. Delete your own copy quietly and say nothing
  • B. Leave it up and hope nobody noticed
  • C. Post a correction that links to reliable information and, if possible, update or remove your earlier share ✓
  • D. Share a different false story to balance it out

Why: Publicly correcting your mistake with a reliable source helps others who saw the original post, and updating or removing it limits further spread.
