These datasets, along with the rules governing them, are a bit more complicated than weighing 4chan and wiki equally. They absolutely weigh peer-review journals and white-listed encyclopedia sources higher. Once they establish a baseline of credibility and identifying a certain grade-level of communication, along with identifying critical-thinking patterns (fallacies, formal logic, etc.)., then you can quite easily filter out the noise.

Every single time I’ve used a GPT to analyze a conversation with a Trump supporter and myself, it has identified their fallacies I had already identified, and rightfully pointing out fallacies of my own at times – but almost always concludes their argument is far, far worse.
