People today are drowning in awareness of suffering with nowhere productive to put it. This is a problem that social technology research can and should tackle! At our #CSCW2026 workshop, we’ll spend the day exploring how to design toward sustainable care. Apply by Aug 3: positech.github.io/cscw2026

Our new article in @science.org enables social media reranking outside of platforms' walled gardens. We add an LLM-powered reranking of highly polarizing political content into N=1256 participants' feeds. Downranking cools tensions with the opposite party—but upranking inflames them.

i think it is a sign of low character to post something controversial knowing it will get angry comments and then insult the people who responded to your ragebait

AI companions aren’t science fiction anymore 🤖💬❤️ Thousands are turning to AI chatbots for emotional connection – finding comfort, sharing secrets, and even falling in love. But as AI companionship grows, the line between real and artificial relationships blurs.

As infuriating as the conservative SCOTUS is, never forget that America’s genocide against its trans population is the child of “moderate” liberal outlets like the Atlantic and the New York Times, and especially Jesse Singal and Katie Herzog, who made healthy careers out of polishing bigotry.

I'm excited to announce that I’ll be joining the Computer Science department at Johns Hopkins as an Assistant Professor this Fall! I’ll be working on large language models, computational social science, and AI & society—and will be recruiting PhD students. Apply to work with me!

As Mariam Kaba said, "hope is a discipline." As Václav Havel said (well before he helped liberate his country from totalitarianism), “Hope is … is not the conviction that something will turn out well but the certainty that something is worth doing, regardless of how it turns out.”

BREAKING: We're sending an open letter to universities across the country, offering support and urging them to reject pressure to punish international students and faculty for exercising their First Amendment rights. Schools must hold firm against the Trump administration's censorship attempts.

I just sent our university president and provost an urgent request to defend First Amendment freedoms at Stanford, given this administration’s willingness to punish those who disagree with it. I urge you to do the same with your university leaders.

Dear President Levin and Provost Martinez:
 
In light of the recent arrest of a former student at Columbia University and the ongoing threats to fundamental freedoms posed by the current administration, I urge you both to clearly and publicly denounce these dangerous attacks on First Amendment rights. Silence or neutrality in this critical moment risks complicity. Students and faculty urgently need reassurance that Stanford will vigorously protect our community members against threats of arrest, censorship, or sanctions for engaging in constitutionally protected expression.
 
You have consistently emphasized the importance of free speech and academic freedom as foundational to our institution. Now is the time to unequivocally reaffirm those commitments. Our community must know that Stanford stands firmly behind them, ready to use every resource available to safeguard their right to express themselves freely, without fear of intimidation.
 
I urge you to act swiftly and decisively to demonstrate our unwavering dedication to protecting constitutional rights, especially as threats against these freedoms escalate.
 
I have cc’d the Stanford Daily on this correspondence because I believe our entire community should be engaged in encouraging decisive action from our administration at this crucial moment.
 
Sincerely,
 
Hakeem Jefferson
Assistant Professor of Political Science
Faculty Director of the Program on Identity, Democracy, and Justice at the Center on Democracy, Development, and the Rule of Law

Zuck positioned these changes as a return to history practice but, for these policy changes, that is untrue. The specific examples I called out above have been prohibited on the site since I wrote the first set of hate speech standards in 2009. 🧵 8/11

My advisor warned me that academics trend towards bitterness. He encouraged me to intentionally resist this, remember where I came from, and never forget the privilege of getting to spend a life working with knowledge and ideas. He too said that bitterness and resentment is easy.

In high school, my social studies teacher took me aside and told me that "cynicism was the easy path" and that I needed to resist it. It's probably the most important thing I learned in school.

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! 🧵⬇️
