Spitting FIRE holy shit 🔥
A series of tweets from Politico senior legal affairs reporter Kyle Cheney: BREAKING: A federal judge in Massachusetts (the Reagan-appointed William Young) has declared the Trump administration's cuts to NIH grants — ostensibly over Trump's EOs on gender ideology and DEI — are "illegal" and "void." He's ordering many grants restored. YOUNG: "I am hesitant to draw this conclusion, but I have an unflinching obligation to draw it – that this represents racial discrimination. And discrimination against America’s LGBTQ community. That’s what this is. I would be blind not to call it out. My duty is to call it out." MORE YOUNG: "It is palpably clear that these directives and the set of terminated grants here also are designed to frustrate, to stop, research that may bear on the health – we’re talking about health here, the health of Americans, of our LGBTQ community. That’s appalling." YOUNG still going: "I’ve never seen a record where racial discrimination was so palpable. I’ve sat on this bench now for 40 years. I’ve never seen government racial discrimination like this ... I ask myself, how can this be?" "I have the protection that the founders wrote into the constitution, along with imposing upon me a duty to speak the truth in every case. I try to do that. What if I didn’t have those protections. What if my job was on the line, my profession... Would I have stood up against all this? Would I have said, 'you can’t do this?' You are bearing down on people of color because of their color. The constitution will not permit that." "Have we fallen so low? Have we no shame?"

This is, weirdly, the most purely fascist shit anyone in the administration has said so far

- Your health is an asset of the fatherland
- Illness is a failure or a moral failing
- You have a duty to maintain your health
- Healthcare is not a right, it's a finite resource
- Die for the fatherland

amazing how grasping this seems in response to someone doing something, how much he needs to be able to rewrite what you saw. the lesson is to do more things

Legit the best thing any Dem has done to date in response to Trump and it happened because he cared more about serving his constituents than public polling about immigration.

I said my main goal of this trip was to meet with Kilmar. Tonight I had that chance. I have called his wife, Jennifer, to pass along his message of love. I look forward to providing a full update upon my return.

🌟🤖📝 **Boosting human competences with interpretable and explainable artificial intelligence**

How can AI *boost* human decision-making instead of replacing it? We talk about this in our new paper.

doi.org/10.1037/dec0...

#AI #XAI #InterpretableAI #IAI #boosting #competences
🧵👇
Article information Title: Boosting human competences with interpretable and explainable artificial intelligence. Full citation: Herzog, S. M., & Franklin, M. (2024). Boosting human competences with interpretable and explainable artificial intelligence. Decision, 11(4), 493–510. https://doi.org/10.1037/dec0000250 Abstract: Artificial intelligence (AI) is becoming integral to many areas of life, yet many—if not most—AI systems are opaque black boxes. This lack of transparency is a major source of concern, especially in high-stakes settings (e.g., medicine or criminal justice). The field of explainable AI (XAI) addresses this issue by explaining the decisions of opaque AI systems. However, such post hoc explanations are troubling because they cannot be faithful to what the original model computes—otherwise, there would be no need to use that black box model. A promising alternative is simple, inherently interpretable models (e.g., simple decision trees), which can match the performance of opaque AI systems. Because interpretable models represent—by design—faithful explanations of themselves, they empower informed decisions about whether to trust them. We connect research on XAI and inherently interpretable AI with that on behavioral science and boosts for competences. This perspective suggests that both interpretable AI and XAI could boost people’s competences to critically evaluate AI systems and their ability to make accurate judgments (e.g., medical diagnoses) in the absence of any AI support. Furthermore, we propose how to empirically assess whether and how AI support fosters such competences. Our theoretical analysis suggests that interpretable AI models are particularly promising and—because of XAI’s drawbacks—preferable. Finally, we argue that explaining large language models (LLMs) faces similar challenges as XAI for supervised machine learning and that the gist of our conjectures also holds for LLMs.

Going to try and watch Deadwood. In order to incentivize my paying attention to the show, I've decided to count the number of times the word cocksucker is said by a character. I'm calling it the Deadwood cocksucker counter. Ten minutes into the first episode:

Disgusting but hardly surprising that the click-chasing press is sharing off the record comments I made to the dumbest rich people in New York City about the role that Ashkenazi Jews played in inventing nightshades (tomatoes, eggplants, etc). I will continue, undaunted, on my presidential campaign.
