I think it's all about intent.
If we're on the same team and you lie to me to protect me or to throw off my enemies, that's disinformation
>"The Tooth Fairy left that money under your pillow, Billy"
>"The company is doing fine" even though stocks dropped 50% after the CEO resigned
>"Oh your hair looks so good today"
Misinformation comes from malicious intent.
Whether it be to harm a person or populace, or if it's to cover up wrongdoing.
>"Covid will kill everyone if you don't wear the mask"
>"No pressure to sign up, just come down and talk to our sales reps" who work on commission
>"Russia Russia Russia"
There are caveats for both but that's how I understand it.
