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....

The Science of Chilling Effects

How can we know if a law or policy has chilled people’s free expression? Can we use science to find out?

Excited to join @penney.bsky.social, author of a new book on Chilling Effects, & @katygb.bsky.social on Dec 10th to discuss the science of civil liberties

From concerns about social media addiction to urgent civil liberties issues, courts are asking scientists to be arbiters of alleged technology harms. How can scientists reliably inform courts and how can courts interpret our work?

Except this authoritarian regime is too stupid to do so, and in fact is adopting policies to do the opposite, and will accelerate those prices.

Their advantage is their ruthlessness, shamelessness, and wealth; their disadvantage is their stupidity.

A classic authoritarian move is to go after judges. I honestly did not think we would see it in the US because the system is already so politicized and Trump has a 6-3 majority. But here we are.

Opinion: The TikTok ban is already dead in the water No matter what happens next, Donald Trump has already completely undermined the law’s efforts to protect national security from Chinese interference

President Trump delayed the U.S. #TikTok ban, but is his executive order legally sound? The Citizen Lab’s @penney.bsky.social writes for the @theglobeandmail.com, questioning whether the move addresses privacy issues or is purely about political power.

it really is appropriate to view this as potentially the biggest privacy and cybersecurity scandal in American history

Others like @taylorowen.bsky.social, who I link therein, have written similarly about this new era. It requires a different approach to tech regulation but also democratic governance. The law that enacted the TikTok ban weaponizes rather than restrains this new tech/state power.

I wrote about the the TikTok ban in the @theglobeandmail.com. I argue the ban is dead for a few reasons, but mostly because its' design failed to account for the new era that Trump's admin represents: persistent weaponization of tech and state power: www.theglobeandmail.com/opinion/arti...

that Korea does this, immediately, in the face of actual soldiers trying to impose martial law - when members of our own congress voted for a coup hours after the J6 mob stormed congress, and the coup instigator won the next election - is about as scathing an indictment of America as I’ve ever seen

I'm at the National Assembly building. The army is here. And I just saw two soldiers in fatigues getting pushed around by belligerent ajusshis. and they looked legit scared.
