A Word With a Department Behind It
Disinformation is false or misleading information deliberately spread to deceive people, or to secure economic or political gain, and which may cause public harm.
The word's history is unusually revealing. It derives from the Russian дезинформация (dezinformatsiya), apparently taken from the title of a KGB black propaganda department. The term appeared in English print as early as 1887, but only entered major dictionaries in 1985 — Webster's New College Dictionary and the American Heritage Dictionary — and had fully established itself in English political vocabulary by 1990.
So the concept arrived in English as an import, and specifically as the name of a job someone was employed to do. Disinformation is defined as an orchestrated adversarial activity in which actors use strategic deceptions and media manipulation tactics to advance political, military or commercial goals.
Three Words People Use Interchangeably
The field draws a sharp line between three things that ordinary speech blurs together, abbreviated collectively as DMMI:
- Disinformation — false information spread intentionally, designed to cause public harm
- Misinformation — inaccurate information spread unintentionally, stemming from inadvertent error
- Malinformation — information that is factually true, deliberately spread in order to cause harm
The distinction that matters most is intent. Misinformation can become disinformation the moment known falsehoods are purposefully and intentionally disseminated — the content need not change at all, only the knowledge and motive of whoever is spreading it.
"Fake news" has sometimes been classed as a type of disinformation, but scholars distinguish the two. Some researchers caution against using the term in academic writing because of its lack of precision and its contested use in political discourse; others note it remains in use both for demonstrably false information and, more loosely, as a political weapon whose meaning is itself disputed.
Truths Are Ammunition Too
The most counterintuitive part of the definition is what campaigns are actually made of.
Disinformation is implemented through coordinated campaigns that "weaponize multiple rhetorical strategies and forms of knowing — including not only falsehoods but also truths, half-truths, and value judgements — to exploit and amplify culture wars and other identity-driven controversies."
That single sentence dismantles the popular model of disinformation as simply lying. A campaign can run almost entirely on accurate facts, selected and arranged to produce a false impression, and be more effective for it — because every individual claim survives fact-checking. Which is also why malinformation needed its own name: true information, deployed as a weapon, is not covered by any definition built around falsehood.
Seeding, Then Echoing
Research identifies four main seeding methods by which disinformation is introduced online:
- Selective censorship
- Manipulation of search rankings
- Hacking and releasing information
- Direct sharing of false content
Notice that only the last is what most people picture. The others work by controlling what is *visible* rather than by adding anything false at all.
Studies describe the spread as happening in two stages. First seeding, where malicious actors insert the deceptions. Then echoing, where ordinary audiences disseminate the material as their own personal opinions. The second stage is what gives a campaign its reach and its credibility, because the message stops arriving from a stranger and starts arriving from someone you know. Defensive strategies discussed in the field include prebunking and inoculation theory — attempting to expose people to weakened forms of a manipulation in advance, so they recognise it later.
