I made a video about the shutdown, and why this government worker won’t be a pawn.

When the president and Supreme Court are both acting lawlessly, Congress must stand up and stop it.

US science is collapsing and Congress needs to act.

How does the brain decide? 🧠

Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.

After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.

I'd like to commend the lawyers who wrote this complaint on behalf of the professors and employees of the University of California against the Trump administration.

It's a sober legal document with strong claims, but also, this is a fight for public opinion, and this reads like the writers know it.

The conditions that have led to what’s happening in the US today exist in democracies around the world.
They are an inevitable outcome of our collective failure to adapt to fundamental changes in the information ecosystem on which our democracies were originally built.

Check out our new study by @atabk.bsky.social! He tweaked a word list memory task to have hidden rules at encoding, which shifted and created “event boundaries.” People recalled pre-boundary words more, and post-boundary words less. Other fun bits in the paper include a reinforcement learning model!

beautiful, heartbreaking words in this judge's rejection of trump's request

The Executive may succeed for a time in weakening the courts, but over time history will script the tragic gap between what was and all that might have been, and law in time will sign its epitaph.
chrisgeidner.bsky.social Chris Geidner @chrisgeidner.bsky.social · Apr 17
It is an astounding opinion written by an 80-year-old, conservative Reagan appointee who — along with his former colleague, Judge J. Michael Luttig (a note that makes its own point about this moment) — once led what many considered to be the most conservative appeals court in the nation.
It is difficult in some cases to get to the very heart of the matter. But in this case, it is not hard at all. The government is asserting a right to stash away residents of this country in foreign prisons without the semblance of due process that is the foundation of our constitutional order. Further, it claims in essence that because it has rid itself of custody that there is nothing that can be done. This should be shocking not only to judges, but to the intuitive sense of liberty that Americans far removed from courthouses still hold dear. The government asserts that Abrego Garcia is a terrorist and a member of MS-13. Perhaps, but perhaps not. Regardless, he is still entitled to due process. If the government is confident of its position, it should be assured that position will prevail in proceedings to terminate the withholding of removal order. See 8 C.F.R. § 208.24(f) (requiring that the government prove "by a preponderance of evidence" that the alien is no longer entitled to a withholding of removal). Moreover, the government has conceded that Abrego Garcia was wrongly or "mistakenly" deported. Why then should it not make what was wrong, right? "Facilitation" does not permit the admittedly erroneous deportation of an individual to the one country's prisons that the withholding order forbids and, further, to do so in disregard of a court order that the government not so subtly spurns. "Facilitation" does not sanction the abrogation of habeas corpus through the transfer of custody to foreign 3 detention centers in the manner attempted here. Allowing all this would "facilitate" foreign detention more than it would domestic return. It would reduce the rule of law to lawlessness and tarnish the very values for which Americans of diverse views and persuasions have always stood. The Executive possesses enormous powers to prosecute and to deport, but with powers come restraints. If today the Executive claims the right to deport without due process and in disregard of court orders, what assurance will there be tomorrow that it will not deport American citizens and then disclaim responsibility to bring them home?* And what assurance shall there be that the Executive will not train its broad discretionary powers upon its political enemies? The threat, even if not the actuality, would always be present, and the Executive's obligation to "take Care that the Laws be faithfully executed" would lose its meaning. U.S. CONST. art. II, § 3; see also id. art. II, § 1, cl. 8. Now the branches come too close to grinding irrevocably against one another in a conflict that promises to diminish both. This is a losing proposition all around. The Judiciary will lose much from the constant intimations of its illegitimacy, to which by dent of custom and detachment we can only sparingly reply. The Executive will lose much from a public perception of its lawlessness and all of its attendant contagions. The Executive may succeed for a time in weakening the courts, but over time history will script the tragic gap between what was and all that might have been, and law in time will sign its epitaph. It is, as we have noted, all too possible to see in this case an incipient crisis, but it may present an opportunity as well. We yet cling to the hope that it is not naïve to believe our good brethren in the Executive Branch perceive the rule of law as vital to the American ethos. This case presents their unique chance to vindicate that value and to summon the best that is within us while there is still time.

Discussions this weekend made it clear that folks don't necessarily realize that our existing "scientific pipeline" of federal funding for basic research didn't just happen. The entire approach was deliberately designed to work this way, on purpose

Meet Vannevar Bush

He's midway through a stack of paperwork + has a call bell nearby http://hdl.loc.gov/loc.pnp/ds.11801 Vannevar Bush (/væˈniːvɑːr/ van-NEE-var; March 11, 1890 – June 28, 1974) was an American engineer, inventor and science administrator, who during World War II headed the U.S. Office of Scientific Research and Development (OSRD), through which almost all wartime military R&D was carried out, including important developments in radar and the initiation and early administration of the Manhattan Project. He emphasized the importance of scientific research to national security and economic well-being, and was chiefly responsible for the movement that led to the creation of the National Science Foundation (NSF). https://en.wikipedia.org/wiki/Vannevar_Bush

Seeing a lot of anger over people in ICE detention having to eg file habeas claims on their own.

There are existing efforts to support these folks: not just full legal rep, but partial assistance (easier to scale).

When a person is abducted, there's a number to call to report & identify. A habeas petition challenging the abduction is electronically filed in that district, by a lawyer admitted in that district, within 30 minutes of the call. Anywhere in the country, 24 hours a day.

Nothing else is good enough.
