A very good research! I wonder how this would replicate for other languages.
People often claim they know when ChatGPT wrote something, but are they as accurate as they think?
Turns out that while general population is unreliable, those who frequently use ChatGPT for writing tasks can spot even "humanized" AI-generated text with near-perfect accuracy 🎯

Dear, @bsky.app , please, implement bookmarks right away.
New paper: Do social media algorithms shape affective polarization?
We ran a field experiment on X/Twitter (N=1,256) using LLMs to rerank content in real-time, adjusting exposure to polarizing posts. Result: Algorithmic ranking impacts feelings toward the political outgroup! 🧵⬇️
