You think #deepfakes are the most common type of visual misinformation?
Nope, it's using pristine media *out of context*. That is, take a real image/video and caption it with a different story.
That kind of #cheapfake makes >40% of visual misinfo, deepfakes only <20%

Yes, #AI will and already *is* influencing elections. We see #disinformation campaigns (like "Doppelganger") that aim to deform even entire political landscapes 😓

Turns out, #LLMs tend to generate more false or unsupported claims in later sentences of long outputs.
So, better double-check when you ask #ChatGPT to write your next essay. 😉
