Misinformation is false/misleading information spread with no ill intent. Disinformation is false and usually propaganda that was created to mislead people.
Misinformation is spread with no ill intent while disinformation is spread with the intent to deceive people.
Misinformation could spread misleading statistics accidenally from a public figure, and disinformation could warp peoples opinions and thoughts on many things.
Both types of information are being spread on social media through public figures, the algorithm, and other ways social media can promote this information to benefit themselves.
AI can be used in many ways to help spread the disinformation/misinformation by creating fake accounts and changing content to their favor.
Video and audio are large parts of the problem because they can use this to create fake videos and audios that show people sayin or doing things that never really happened.
The spread could start off with something someone said like a celebrity or public figure or even somebody random, then people who get influenced or look up to the person can start spreading it, leading to more peple following the crowd and doing the same.
Fake news is related to the two types of information because it could be classified as either one of them due to it being fake stories/news on the internet.
These types of fake news on the internet are hard to tell if they are credible due to the way social media is set up which leads to one person believing and then many more joining.SOURCE SOURCE
