LLMs excel at mimicking individual text, but what about collective conversations? 🤔
In our recent paper 📄, we conducted a Turing Test to see if GPT4 and Llama 3-generated social media conversations can fool humans into believing they're authentic!

Misinformation research has a causality problem: lab experiments are limited; observational studies confounded.
We used causal inference on 9.9M tweets, quantifying effects in the wild while blocking backdoor paths.
Does misinfo get higher engagement? Are following discussions more emotional? 🧵

Honest people don’t lie. Or do they? Liars aren’t honest. Or are they?
One puzzling conundrum in contemporary politics is that politicians who seem to be estranged from facts and evidence are nonetheless considered honest by their followers.

How politicians communicate shapes online discourse in ways we might overlook.
Our new paper shows that their choice between a fact-based (evidence-driven) and a belief-based (sincerity-driven) honesty creates a "contagion" effect, influencing how users engage and respond. ⬇️(1/8)

It's supercool that Deepseek v3 is open, but it's pretty censored at least through the Android app. It refused to answer about Tiananmen and when asked about the capital of Taiwan, it deleted the output mid-generation.
