Delighted and thankful that our study "Election Polls on Social Media: Prevalence, Biases, and Voter Fraud Beliefs" (attached thread) received Best Paper Honorable Mention at @ICWSM'25! Congratulations @StephenAI @vijayalaks26304 @hide_yourself @yang3kc @junghwanyang! 🙏🎊
First paper🔬 on social polls!!!🗳️
Over 100k polls gauged support for 2020 US presidential candidates on @X, and gathered >20m votes. They favored Trump by >10% (on average). Many were used to reinforce voter fraud beliefs and were likely manipulated by bots and fake votes.

Our bias-corrected estimates of support for US presidential candidates based on @X polls were more accurate than traditional polls! 🎊🎉
We estimated 52% for Trump vs 48% for Harris. So far there are 72,641,564 votes for Trump (51.7%) and 67,957,895 for Harris (48.3%)!

Don't believe everything you see on social media.
Informal political polls conducted on X during both the 2016 and 2020 U.S. presidential elections were significantly skewed by questionable votes.

Do you ever get bored of seeing same recommendations from @YouTube? By developing OtherTube, @snaglee2401 @tanmit @carlosabauti and I studied how swapping recommendations with strangers can help burst algorithmic filters #CHI2022 arxiv.org/abs/2201.11709 youtu.be/Br4ZEVG_tsk

This NudgeCred paper took only 4 yrs to be published. Still one of my favorite papers! The idea was hatched in 2017, after 3 yrs of rejections, it finally found its home at CSCW this year. Today seems to be the day to talk about paper rejections turning into acceptances #CHI2022
Excited to present two #CSCW2021 papers with my co-authors @tanmit @snaglee2401 @mhorning in the Misinformation, Conspiracies, and Manipulations session today. Links to the pre-recorded presentations: youtube.com/watch?v=TQpeRpcD… and youtube.com/watch?v=oC9thtav…
