Except literally every data analysis or model I've ever asked AI to build has contained at least one error: www.nature.com/articles/d41...

Common response: "But someone just needs to give AI detailed instructions..."

But who is the "someone" in that sentence? And how did they get their expertise?

the Epstein files are really devastating because they remind me of how many girls and women miss out on professional opportunities, mentorship and careers because of how many powerful, rich and influential men only view girls and women β€” and interactions with them β€” through the lens of sex

it is not just that there are no "levers" language is a huge barrier to understanding

If you or anyone you know has missed their vaccination, it’s never too late to get caught up for FREE on the NHS. You protect you and everyone around you.

Want to get the data out of a PDF figure? As in, the actual data – not a rough trace-along-the-lines version?

I made an app you might like: adamkucharski.github.io/pdf2plot/

This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!

The government's keenness to protect "good jobs" in manufacturing contrasts with its inaction in the face of the destruction of "good jobs" in universities. What's going on here is something other than economics.

NEW! 🦠🦧 We revisited a perplexing paradox: do wildlife really pose less of a risk to human health as they become more endangered?

RFK Jr.’s Miasma Theory of Health Is Spreading The agency is picking up Robert F. Kennedy Jr.’s argument that a healthy immune system can keep even pandemic germs at bay.

Relying on personal nutrition and exercise as the main pandemic strategy is a nice idea, but it leaves huge swaths of the pop exposed. Individual agency just isn’t equitable! people don’t all have the same time, resources etc to β€˜optimise’ themselves to safety

You cant parachute asylum seekers into deprived areas, in completely inappropriate housing, then say those migrants are 'dividing our country'. You divided the country because you can't organise a basic service and process claims in a timely way

Opinion | Jamal Khashoggi: What the Arab world needs most is free expression The Arab world needs a modern version of the old transnational media so citizens can be informed about global events.

I will never forget having to edit Jamal’s final, posthumous piece for the Washington Post, after he was murdered.

He was calling for free expression in the Arab world. You can read it here :

Kids have a right to vaccinations. Let's bring in the lawyers Children suffering from diseases that should have been consigned to history is a moral failure. Access to vaccines is a human right.

Kids rely on adults for safety, but when adults & governments are intentionally spreading anti-vax misinformation, or actively reducing access to essential vaccines, who is to protect kids and safeguard their rights?

Important to understand the Epstein stuff and the fascism and the corruption are, in a lot of ways, really all the same story from different angles: powerful men who can and do abuse vulnerable people around them because they can, and because systems of elite accountability catastrophically failed

In rural Liberia, reaching every child means crossing rivers by raft and navigating miles of dangerous, mud-slicked roads. But due to a lack of funding, many of these vaccinators do it without pay. 🧡

EVERY left-leaning media outlet contributes to thisβ€”most are instigators.

+ most Dem politicians, especially ones who pass legislation sponsored by groups like EWG.

Selective science denialism crosses ALL ideologies β€”bc strong opinions replace logic even with those who think they follow data.

Their parents never got them vaccinated. As young adults, they faced a choice. Falling vaccination rates around the country mean more will grow up without protection from debilitating diseases until they are old enough to decide for themselves, typically at age 18.

Another risk of a vax-hesitent population: folks don't realize they're missing vaccines.

Those in this story found out after enlisting in the military or starting hc jobs that require proof of immunity, or the hard way - by catching vax-preventable diseases.

I don't know where this revisionism has come from about the suffragettes - people saying "if the suffragettes were around today, they'd be considered terrorists."

The suffragettes were arrested and tortured, sexually assaulted and beaten by the state. They *were* considered terrorists!

It’s easy to disregard the value of vaccines and modern medicine and science when 9 out of 10 of your siblings didn’t die prematurely. How do we convey that to people - that the absence of tragedy is not the absence of risk
