"Chilling effects can be subtle, but today they are everywhere. And it’s not just students who are chilled by Trump administration threats." @penney.bsky.social, author of Chilling Effects, on Donald Trump and free speech for @theconversation.com #LawSky #PoliSky https://cup.org/4fIEAFl

Chilling effects of Trump’s war on free speech extend far beyond campus walls – and that’s the point

A persistent government strategy to sow fear through punitive measures has corroded freedom and democracy.

Curtailing freedoms is the *point* of authoritarian policies and the desire of authoritarian politicians.

Bruce Schneier (@schneier.com) and I have a new essay in @theconversation.com on the Trump administration's strategy of weaponizing law, technology, & surveillance to chill protest, dissent, & political opposition. In short, the chilling effects are the point. theconversation.com/chilling-eff...

Researchers say fear of arrests, deportations and retaliation is creating a “chilling effect” that’s keeping many students from protesting — even as young Americans sour on Trump. theconversation.com/chilling-eff... #polisky

@salon.com has picked up my essay (co-authored with Bruce Schneier) on the Trump's admin's weaponization of law, tech, and surveillance to chill protest and opposition. We link recent reporting on lack of student protests/activism to this broader Trump admin strategy. www.salon.com/2026/05/28/t...

"We believe students aren’t protesting for a very simple reason: They are afraid. They are self-censoring and disengaging from campaign activism to avoid punitive measures," says senior research fellow Jon Penney @penney.bsky.social in his new essay for @theconversation.com.

Most chilling effects scholarship focuses on law's direct inhibition of speech. @penney.bsky.social new book asks a harder question: what about the indirect effects on conformity and power? We discuss on this week's Law Bytes podcast.

"Chilling effects" is a term everyone uses and few people interrogate. @penney.bsky.social joins the Law Bytes podcast to discuss his new book and why we may be understating the issue, with implications for surveillance, content moderation, and AI regulation.

What does it take to prove causality in tech harms cases? After rulings in NM & CA, commentators are throwing around causality in arguments both for & against the results. If you’re frustrated by the causality maze, don’t worry- @penney.bsky.social & I have you covered tsjournal.org/index.php/jo...

Chilling effects are hard to measure or document. They are what doesn't get said over here, because of some gvt action over there. But pieces like this are a small part of making visible what is obvious: right now, chilling effects are everywhere www.nytimes.com/2026/03/16/u...

More transparency is a critical component that in theory should be relatively easy to implement. Along with @penney.bsky.social & Niamh Leonard, we argued that such transparency is critical to the system's functioning: www.sciencedirect.com/science/arti....
