I mean, it’s a little more than that, but only a little. There’s a literal meter in your screenshot of how left or right the source is. “Credibility rating” requires us to trust MediaBiasFactCheck’s credibility rating system, which I don’t know enough about at the moment and so default to not trusting it.

That’s why I say calling out the problematic structures would be more helpful - people could see it for themselves, right there in the article text, and then maybe also identify then without help later. This would foster healthier discussion than an echo chamber where people ignore a source based on its biases.

Of course some sources would be more note than content, but then some sources have argued in court they’re not really news.
