Three-way contrast
| Term | Truth value | Intent | Example sketch |
|---|---|---|---|
| Misinformation | False or misleading | Not required to prove intent | Sharing a wrong dosage chart you believed |
| Disinformation | False or misleading | Deliberate deception | Fabricated "official" notice meant to confuse voters |
| Malinformation | Based on reality | Shared to cause harm | Leaking a private medical detail to shame someone |
The World Health Organization's infodemic materials discuss the flood of information during health emergencies, including false and misleading content that can harm health decisions. Secondary explainers in journalism education popularized the mis/dis/mal split for classrooms; always check whether a given agency uses all three labels or only the first two.
Why intent is hard on a deadline
Reporters can often show falsity faster than they can prove a speaker's private intent. That is why careful outlets describe a claim as false first, and reserve "disinformation" for cases with strong evidence of coordinated deception.
Malinformation disputes are often legal and ethical (privacy, harassment) rather than fact-checkable true/false questions.
Workflow for readers
1. Separate "is this accurate?" from "why was it posted?"
2. Find a primary document or dataset when the claim is quantitative.
3. If the post uses a real document, ask whether the framing omits context that flips the meaning.
4. Only then guess at intent, and keep that guess labeled as uncertain.
Overlap with propaganda devices
Disinformation campaigns often borrow bandwagon language or transfer symbols. The taxonomy here is about truth and intent; propaganda device lists are about rhetorical technique. Use both lenses.
What this page is not
It is not a criminal statute. Legal definitions of fraud, defamation and illegal threats differ by country.
It is not a license to dismiss every disagreeable claim as disinformation. Overusing the word drains it.
Teaching note
Give students three cards: a wrong rumor shared in good faith, a forged screenshot, and a true but doxxing post. Have them sort the cards before you reveal the labels. The sorting conversation matters more than memorizing Greek prefixes.
Health emergency context
During outbreaks, WHO and partner agencies warn about infodemics: too much information, including false and misleading advice that can cause people to reject vaccines, take unproven drugs, or ignore contact guidance.
A neighbor forwarding an outdated mask chart is often misinformation. A forged ministry letter inventing a fake curfew is disinformation if created to confuse. Doxxing a nurse's home address after a shift, using real data, fits malinformation patterns even when every digit is accurate.
Platform labels vs scholarly labels
Social networks may use "false information," "altered media," or other product-specific tags. Those tags will not always map 1:1 onto mis/dis/mal. When you quote a platform label, say which system produced it.
Academic papers sometimes collapse malinformation into broader "information disorder" frameworks from First Draft and related research groups. If you teach the three-term split, show students a second framework once so they do not think the vocabulary is universal law.
Evidence ladder for writers
Tier A: primary documents, raw datasets, on-the-record admissions of fabrication.
Tier B: reputable secondary reporting that links to Tier A.
Tier C: anonymous rumor screenshots.
Do not call Tier C "disinformation" in a headline. Call it unverified. Upgrade the word when the evidence upgrades.
Repair moves after you shared something false
Delete is not enough if the post already spread. Issue a correction with the same channels and a plain statement of what was wrong.
Link the better source above the fold, not in a buried comment.
If you harmed someone with true private information, corrections will not undo the privacy loss; seek legal and ethical counsel rather than compounding the post.
Assignment ideas
Have teams redesign a false health meme into a corrected graphic with citations.
Have another team map a rumor to the three labels and defend why intent is or is not knowable.
End with a discussion of overuse: when "disinformation" becomes a slur for ordinary disagreement, the taxonomy fails its public purpose.
Boundary cases that stress the three labels
A neighbor forwards a fabricated clinic closure notice that she believes is real. The content is false, but her intent is warning, not sabotage. Under the Wardle and Derakhshan information-disorder axis, that is misinformation until you can show she knew it was false and still pushed it to panic people.
A political shop edits a real video clip to invert who threw the first punch, then seeds it through cutouts. The clip has a documentary root, but the package is built to deceive. That pattern sits closer to disinformation because falsity and coordinated intent travel together.
A dump of a genuine private medical file, published to humiliate someone who told the truth in public, is the classic malinformation shape: the facts can be accurate while the use is weaponized. Debunking "falsehood" alone will miss the harm mechanism.
Hybrid cases are normal. A rumor can start as honest error, then be amplified by actors who later learn it is false and keep pushing it. Label the stage you can evidence, not the entire lifecycle with one word.
Intent evidence: what is enough on a deadline
Intent is a claim about minds. Newsrooms rarely have courtroom-grade proof of what a poster "really meant" in the first hour. The safer reporting move is to separate (1) what is false or out of context, (2) how it spread, and (3) what evidence of coordination or knowing falsehood you actually hold.
Useful intent signals include: repeated posting after corrections, fabricated documents with deliberate metadata, sockpuppet networks, paid amplification, or internal messages that show planning. Weak signals include: the poster belongs to a disliked group, the claim is popular, or the claim helps a side you oppose.
If intent evidence is thin, say "false claim" or "unverified rumor" instead of jumping to "disinformation." Reserve the stronger word for when circulation patterns plus knowing falsity (or organized deception) are documentable. That discipline is part of the same media-literacy frame that defines the three terms.
Malinformation needs a different proof load: show the material is substantially genuine and show the publishing choice is aimed at harm (doxxing, revenge leaks, selective true quotes stripped of context to destroy someone). Accuracy of the underlying fact does not cancel the ethics problem.
How this maps to propaganda devices and FRAME
Propaganda device lists (bandwagon, transfer, card stacking, and neighbors in Hollowvane's FRAME-linked pages) describe rhetorical moves. Mis/dis/mal describe truth status plus intent. A bandwagon appeal can carry true turnout numbers or fake ones; the device label and the information-disorder label answer different questions.
Use both layers when teaching. Ask: which persuasive device is visible in the copy? Then ask: is the payload false, and can we evidence intent to deceive or to weaponize something true? Students who only learn device names under-detect sincere error. Students who only learn mis/dis/mal under-detect classic persuasion tricks on true claims.
FRAME-style example indexes are useful for spotting techniques in the wild. They do not replace the Wardle and Derakhshan axis for classifying information disorder. Keep the Council of Europe / First Draft lineage citation in sources when you teach the trio, and do not hang the page on unrelated psychology dictionary entries about memory effects.
In practice: open with the three-way table, then drill one propaganda device that often rides along (for example transfer of authority), then run a labeling exercise that forces students to withhold "disinformation" until intent evidence appears.
Newsroom and classroom micro-drills
Drill A: give three cards (false sincere share; false coordinated campaign; true revenge leak). Require a one-sentence label plus the missing evidence that would change the label.
Drill B: take a viral post and write two graphs: one that only verifies facts, one that only asks about intent and harm. Compare which graph would stop a share.
Drill C: rewrite a headline that says "disinformation spreads" into a headline that states what was false and what is known about the distributors. Precision usually shortens the word and lengthens the usefulness.
These drills stay inside the same definition axis. They add practice volume without inventing a fourth category or smuggling in unrelated "misinformation effect" memory research.
