Rumor
A rumor is an unverified claim that circulates from person to person or account to account, often about a matter of public concern, without confirmation from a reliable source.

How rumors form and travel
Rumors tend to appear when a subject is important, the facts are unclear, and official information is slow or absent. People fill the gap. A layoff, a product incident, a merger or a safety event are typical triggers. Once a claim is stated in a concrete, easily repeated form, it can travel faster than the organization can gather facts.
The rumor may be true, false or partly true. That uncertainty is what defines it: the claim is not yet confirmed. If it is false and repeated, it becomes misinformation. If someone is pushing it on purpose, it is disinformation.
Examples
A hypothetical example: employees of a large retailer begin sharing a screenshot of an internal memo that says a set of stores will close. The memo might be real, edited, or invented. Local news accounts pick it up, and customers ask store staff about it. The company has to decide quickly whether to confirm, deny or say that it will provide information by a given time.
Why it matters to communications and risk teams
A rumor is a leading indicator. It often shows up in comments, forums and messaging groups before it reaches journalists. Tracking early mentions of a claim, and the phrasing people use for it, gives a team time to prepare a response and to decide whether to correct it publicly. A public correction can spread a rumor to people who had not heard it, so the size of the audience already exposed is part of the decision.
Teams that publish a regular, reliable stream of facts during an incident give rumors less room. That is a core theme of crisis communications.
How teams measure a rumor
Useful measures are first appearance, growth rate, the number of distinct accounts, the channels involved and whether journalists or officials have picked it up. Comparing the rumor's wording across posts shows which version is winning. Tracking the same measures after a statement is published shows whether the statement reached the people who saw the rumor, which is more informative than the volume of replies alone.
Common misconceptions
Silence does not make a rumor go away; it usually leaves the field to others. Denying a claim that is partly true also carries a risk, since a later confirmation of the true part undermines the denial. Rumors are not confined to fringe corners of the internet. They frequently move through workplaces, customer support channels and professional networks.
The volume of a rumor is not a measure of its truth, and the fact that many accounts repeat a claim is not evidence that they observed it independently.
