Um, ICE just coldly shot an unarmed PRIEST in the head w a pepper ball when he (and everyone around him) clearly posed no threat.

For the crime of … complaining about government policy.

Core 1A speech.

With cameras rolling, they’re sniping priests for sport.

This is out of hand. These agents are there to cause trouble and violence, not to keep people safe. These are the scenes that play out in war torn, destitute countries - not America.

Emergency Triad: The Chicago Rubicon and What Comes Next We aren’t at the worst-case scenario yet. But if you squint, you can see it looming out there, just over the horizon.

As alarmed as people may be, they aren't alarmed enough. Trump just escalated this crisis from a fight between the federal government and a state, to a situation where one state is deploying armed forces to impose its will on another state. www.thebulwark.com/p/emergency-...

Dealing with dangers like this is why it’s completely clear that police need far harsher powers to deal with protest.

Really enjoyed my weekend read on 𝐚𝐜𝐭𝐒𝐯𝐞 𝐟𝐒π₯𝐭𝐞𝐫𝐒𝐧𝐠: local recurrence amplifies natural input patterns and suppresses stray activity. This review beautifully argues that sensory cortex itself is a site of memory and prediction. Food for thought on hallucinations!

Imagine an apple 🍎. Is your mental image more like a picture or more like a thought? In a new preprint led by Morgan McCartyβ€”our lab's wonderful RAβ€”we develop a new approach to this old cognitive science question and find that LLMs excel at tasks thought to be solvable only via visual imagery. 🧡

Stop blaming migrants and tackle UK’s real problems, 100 charities tell home secretary A letter warns Shabana Mahmood that β€˜targeting refugees will do nothing to tackle’ problems with housing and the NHS

Can we all just shout about how despicable it is to scapegoat migrants for everything? Can we just stop being too polite or shy about it? Can we condemn it at work, with friends, family, on SM, everywhere? Can we just not keep calm & carry on until it’s too late?

What does postdiction show about the speed of consciousness? In this forth. piece in BBS, I respond to @smfleming.bsky.social + @matthiasmichel.bsky.social's claim that postdiction shows consciousness is slow -- too slow for its purpose to be online action guidance. 1/3 philpapers.org/rec/PHIPAT-14

My photo shows a mosaic fragment from the floor of a Roman villa in Spain, dated AD 100-200s. It depicts a cartoon-like, stylised octopus using red, yellow, white, and black limestone tesserae, against a white background. The front-facing octopus has a large red and white head/body outlined in black. Its yellow circular eyes are outlined in black with a central black dot. Below the head/body are eight writhing tentacles

You’re not an β€œopen, tolerant, generous country” unless you welcome people on equal terms. Five years residency is a fairly standard condition for citizenship, as is being able to support yourself financially. But these additional requirements are performative and unnecessary.

Mahmood demands migrants earn right to settlement in UK New tests will include learning English to a high standard, paying National Insurance and not claiming benefits.

Once again, a UK government seeks to impose conditions upon immigrantsβ€”β€œnot taking a penny in benefits”, volunteering in your communityβ€”that it doesn’t demand of its own citizens. That’s discriminatory. Racist even. www.bbc.com/news/article...
