According to the American Psychological Association, "Misinformation is false or inaccurate information — getting the facts wrong."
The main difference between misinformation versus disinformation is that even though the facts are wrong, misinformation is not being spread deliberately to support a certain agenda. However, the outcome can be the same in that many individuals will make important life decisions based on inaccurate information that can have negative real-world consequences. It often spreads from not taking the time to vet sources and facts.
