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.

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.

[Mattia Samory @hide_yourself]

@enfascination Curious of your choice, but more so of the parameters you used for deciding

[Mattia Samory @hide_yourself]

@indiiigosky Woot congratulations!

[Mattia Samory @hide_yourself]

@asbruckman It follows a different solution path to your question, but I found “unpleasant design” to be a refreshing critique to interventions that ignore or antagonize user goals https://t.co/7mRwe5XEGo
