Study of 8k Posts Suggests 40+% of Facebook Posts are AI-Generated

Originality.AI looked at 8,885 long Facebook posts made over the past six years.

Key Findings

  • 41.18% of current Facebook long-form posts are Likely AI, as of November 2024.
  • Between 2023 and November 2024, the average percentage of monthly AI posts on Facebook was 24.05%.
  • This reflects a 4.3x increase in monthly AI Facebook content since the launch of ChatGPT. In comparison, the monthly average was 5.34% from 2018 to 2022.

  • Keep in mind this is for AI generated TEXT, not the images everyone is talking about in this thread.

    Also they used an automated tool, all of which have very high error rates, because detecting AI text is a fundamentally impossible task

    • Yeah. This is a way bigger problem with this article than anything else. The entier thing hinges on their AI-detecting AI working. I have looked into how effective these kinds of tools are because it has come up at my work, and independent review of them suggests they're, like, 3-5 times worse than the (already pretty bad) accuracy rates they claim, and disproportionatly flag non-native English speakers as AI generated. So, I'm highly skeptical of this claim as well.

    • AI does give itself away over "longer" posts, and if the tool makes about an equal number of false positives to false negatives then it should even itself out in the long run. (I'd have liked more than 9K "tests" for it to average out, but even so.) If they had the edit history for the post, which they didn't, then it's more obvious. AI will either copy-paste the whole thing in in one go, or will generate a word at a time at a fairly constant rate. Humans will stop and think, go back and edit things, all of that.

      I was asked to do some job interviews recently; the tech test had such an "animated playback", and the difference between a human doing it legitimately and someone using AI to copy-paste the answer was surprisingly obvious. The tech test questions were nothing to do with the job role at hand and were causing us to select for the wrong candidates completely, but that's more a problem with our HR being blindly in love with AI and "technical solutions to human problems".

      "Absolute certainty" is impossible, but balance of probabilities will do if you're just wanting an estimate like they have here.

      • I have no idea whether the probabilities are balanced. They claim 5% was AI even before chatgpt was released, which seems pretty off. No one was using LLMs before chatgpt went viral except for researchers.

  • If you want to visit your old friends in the dying mall. Go to feeds then friends. Should filter everything else out.
