So very excited [these](www.foundationalpapersincomplexityscience.org) arrived today!! I doubt I'll ever get through them all, but I always get inspiration and ambition from the complex systems perspective.

Harvard has set an example for other higher-ed institutions - rejecting an unlawful and ham-handed attempt to stifle academic freedom, while taking steps to make sure students can benefit from an environment of intellectual inquiry, rigorous debate and mutual respect. Let’s hope others follow suit.

Today I lost an NIH grant training clinicians to do research about intimate partner violence with perinatal women.
More women are murdered in the perinatal period than die of obstetric complications.
I didn't just lose a grant. We lost an entire cohort of people building careers to prevent that.

I think we have enough evidence to now argue that AI is not getting exponentially better, or even linearly better. It is asymptotically converging on a level of inadequacy, and even that is only happening because the data thieves are still stealing everything that isn’t nailed down.
I’ve lost patience with the claims that (a) AI will somehow get better (b) there are patterns of use that are genuinely useful. Maybe so, but those are not what I’m seeing.
And the cheerleaders who tell my students that AIs are the future are, I think, morally culpable.

Have not been able to tear myself away from exploring these just received spatial transcriptomics data from the septum and surrounding nuclei in human 🧠. Fascinating to explore since there are no comprehensive spatial gene expression data across these regions yet available in human brain.

Hallucination is totally the wrong word, implying it is perceiving the world incorrectly.
But it's generating false, plausible sounding statements. Confabulation is literally the perfect word.
So, let's all please start referring to any junk that an LLM makes up as "confabulations".

petition to change the word describing ChatGPT's mistakes from 'hallucinations' to 'confabulations'
A hallucination is a false subjective sensory experience. ChatGPT doesn't have experiences!
It's just making up plausible-sounding bs, covering knowledge gaps. That's confabulation

Students should study the humanities not because it makes them better workers but because it rips you open and breaks your brain and changes everything you thought you knew. I *promise* you this. I *promise* it has this ability, no matter how smart you think you are. I have seen it countless times.
Hearing the president of KU say that the way the humanities can protect itself - a question asked by a humanities professor of Spanish - is that her field should direct its public voice to how the Spanish language can impact AI versus the third study of an obscure play…. Just sigh.

We've been analyzing emotion regulation patterns of brain activity lately. Depressed people who regulate more when asked, after seeing negative images, regulate better. But those who regulate more when not asked think more about suicide after stress.
