Emotion and novelty attract attention, trusted messengers encourage acceptance, and repetition makes a claim familiar even after its source fades. These mechanisms help explain diffusion without proving that every person who shares the item believes it.

Start with the original claim and independent evidence. Then trace exposure, belief, recall, sharing, and correction separately; each is a different outcome, and the coexistence of rumor and belief does not establish causal direction.

Correction effects depend on source, timing, repetition, and what replaces the false explanation. A correction may improve factual accuracy without changing a connected policy preference, so belief and political judgment should be measured separately. Analysts should also avoid assuming that every sharer believes a claim; people may repost to criticize, ridicule, signal identity, or attract attention.

A false election notice shows why intent and effect must be separated. A post says that the city canceled an election, while the original notice merely moves one polling location. The notice establishes falsity. A misunderstanding would make the post misinformation; evidence that its author knowingly altered the notice to deceive would support disinformation. Researchers must still distinguish who encountered, believed, repeated, or abandoned the claim after correction.

A disputed prediction or value judgment is not automatically misinformation. The label belongs to a claim that can be checked against evidence, not merely to an argument the analyst rejects. Corrections also need not erase every consequence: a person may accept the factual correction while retaining a policy preference based on other reasons. Sharing alone does not prove belief or deceptive intent. Independent corroboration and original context establish accuracy; evidence of the communicator's knowledge is needed before inferring deliberate deception. An experiment that varies correction exposure can estimate the correction's effect on measured belief, while the simple coexistence of rumor and belief cannot establish which caused which.
