The Risks of the 'Observer Effect' from Being Watched by AI | TechPolicy.Press Dr. Koustuv Saha says if users begin to feel their privacy is compromised, they may stop using AI in the very ways that make it useful.

One reason LLMs are so popular is the promise of seemingly private, judgment-free interaction. But once users internalize that their data is being recorded, studied, or reused, it could lead to a shift in how people think, speak, and even feel when using AI, says computer scientist Koustuv Saha.

I'll never forget the moment my first #ICWSM paper was accepted in my PhD's 2nd year. I told @munmun10.bsky.social, "I can't explain how happy I am." I was overjoyed to be a part of this community. Each ICWSM has been so enlightening and emotional---and this recognition brought it all back. ❤️

So honored to receive this recognition. Can't thank enough those who supported me along the way. Feels like a dream to receive an award named after two legends, @ladamic.bsky.social @nglance.bsky.social. #ICWSM is special to my heart, sad to have missed it this year. Thank you, @icwsm.bsky.social. ❤️

In another #CHI2025 paper led led by Charlotte Lambert, in collaboration with @kous2v.bsky.social, we conducted a quasi-experimental study and found that Reddit users who received “high scores” and “gold” made more frequent and higher quality posts (i.e., higher scores and fewer removals).

Continuing our work on LLMs for content moderation, our #NAACL2025 shows that SLMs can outperform LLMs with higher accuracy, better recall, and easier fine-tuning for community norms—making them a scalable, convenient, and cost-effective choice. /w @agam-goyal.bsky.social @ceshwar.bsky.social
