Misinformation

Misinformation is information that is incorrect, but not because of a deliberate attempt to mislead. Believers in misinformation are said to be misinformed but not lying. It is commonly confused with disinformation. The spreading of disinformation is a purposeful attempt to spread a known falsehood, whereas misinformation is the result of ignorance.
