Amazing new paper analysed 10 million news posts on 7 social media platforms in January 2024 - they found that most content posted is high quality and politically moderate, including on Twitter/X. The problem is that engagement is much higher for the relatively small portion of low quality content.

1)Right-leaning platforms=lower quality news
2)Echo-platforms: Right-leaning news gets more engagement on right-leaning platforms, vice-versa for left-leaning
