At the bank I was told "pick your four digit pincode but it can't be a year." "Aren't they all years?" I asked. We sat in silence for a bit.

New article out this month on how doctors become fascists.

50% of German physicians joined the Nazi Party––twice the proportion of any other profession. US doctors today are arguably the most conservative in the world, and we're heading along a similar path.

This text book situation is an extreme example (and a particularly horrific one) but we already see future doctors struggle with learning the critical thinking that is a staple of the humanities. Much of AI use deprives people of that meta cognition so essential to higher learning.

A student on TikTok has been documenting her journey with a professor who “wrote” the anatomy textbook and it’s all a bunch of AI hallucinations.

She’s saying that, understandably, the students are doing super poorly!

Behold what we’re teaching the healthcare professionals of tomorrow:
A diagram of the bones and (some) deep muscles of the hand and forearm. AI says that we only have four digits. It’s also identified a tendon as the median nerve, another tendon as the ulnar nerve, among other issues. An AI generated diagram of the muscles of the neck. It hallucinated the “ennocleidomasid” muscle, and the “anterior scalpalin muscle”. An AI generated diagram of the muscles of the lateral thigh. It says that the gluteus Maximus (the big juicy butt muscle) is on the anterior side. It also points to the quadriceps muscle and says “attattment”. It also says that the same structure is the tibia AND the deep fascia of the leg. An AI generated diagram of the bones of the hand and forearm. This time AI says we have 6 digits. It also says that the radius is the ulnar artery. Among other many issues.

As I argue in #PlatypusMatters, Australia has the world's best mammals, but is sadly the worst place on Earth to be a mammal, with the planet's worst #extinction rate.
The Christmas Island shrew is now the latest species to be officially declared extinct.

And then there were none: Australia’s only shrew declared extinct
The tally of Australian mammals extinct since 1788 is now 39 species – far more than for any other country

This is an exact encapsulation of why I moved to Bluesky.

No amount of handwringing in the Atlantic about how I owe some eternal Promethean suffering to the discourse is going to make me stay on a site I hate, that stopped doing anything for me professionally years ago.
Well – no. Bluesky may or may not be, as one centre-right friend who felt unwelcome put it, “self-righteous island”. But the idea that’s why we went is nonsense. That I’ve largely stopped posting on a site that’s done more to shape my career and social circle than the rest of the internet combined is less about avoiding rival opinions (I love arguing with people who are wrong!) than with the fact the site simply became unusable. It stopped generating the things (good jokes, interesting debate, clicks) I wanted; it became extremely good at generating the things (racists, pornbots, racist pornbots) I did not.

It’s been brought to my attention that it’s World Migratory Bird Day. I can think of no better excuse to share four of my best pictures of the undisputed king of migratory birds - the kuaka (bar-tailed godwit), which boasts the longest non-stop migration on the planet. Alaska-Aotearoa. 🪶🇳🇿

In related news I am presently transcribing a podcast episode covering the OECD's report "Tax Policy Reforms 2025". And guess what Denmark did? Introduce a carbon tax on agriculture aimed at reducing CO2 emissions from agriculture & forestry by 30% by 2030.

I think my data science scripts in 1995 were applescripts connecting a data source in Excel or Filemaker to Adobe Illustrator for plotting maps. It was a few more years before I began processing data in python.

Currently it looks like trade moving away from the US (so likely less US demand being matched by other markets) except some seafood industries maybe be in decline and not finding substitute markets. But I'll get the full notes out in a week or so.

For the NZ Trade Data I am writing a guide for, This is my current standard commodity panel. 1st - monthly change in dollars (h/t @schiff.nz) which suggests if movements between US and non-US amounts are replacements, 2nd (I may yet drop) is US as % of non-US, & 3rd unit value- checks if oversupply

Citations formatting has been highly automated for decades, but most teaching allocate marks for formatting but no teaching time for teaching the tools, and even less technical support for setup and operation. So there is a gap, which in an ideal world would be filled by teaching what is marked.

Even if OpenAI claims it's reducing political partiality in LLM outputs to satisfy conservative agitators, since science is now so politicized that basic sociological concepts like structural privilege are coded "woke", etc etc, then these models must undermine fundamental educational values.

I've strong concerns about online the social licence/trust/ transparency.
Personally, I would rather see synchronisation with general where you get the local a month out (basically as now) and you can drop them off anywhere with advanced voting or on the day. Noting election date (snap etc) issues.

Genuine question: for those enthusiastically pushing AI tools into every part of our education system—what checks/guardrails are there around algorithmic biases like this?

The administration “is currently pressuring OpenAI and other AI companies to make their models more conservative-friendly.”
OpenAI is trying to clamp down on ‘bias’ in ChatGPT
GPT-5 is better at resisting liberal ‘pressure,’ the company says.

Epidemiologists of Bluesky: do you know of any papers that developed statistical models to infer Covid (or something else) incidence or mortality at scale based on survey data about contacts (i.e., “has someone you know died?”)

They are repeating a self-description. In general, I support media describing people the way they describe themselves without editorialising, because the main alternative is the RNZ/Alex situation.

That said, I expect that @thepress.co.nz will have the opportunity to bear witness to lots of local government news stories being generated out of Selwyn over the next few years.
