We can laugh at the use of a piecewise regression to justify improvements post Palantir deployment. But also realise that so many public sector claims like that rely on shaky statistics and bad science, without any transparency of methods.

Bd science behind NHS push for Palantir “The evaluation used […] is a method known as interrupted time series (ITS) analysis. ITS looks at performance before an intervention, assumes that the performance trend would continue, and then attributes post-intervention change to the intervention itself.”

Many voters who use big, old platforms may rarely see age verification practices and not be aware of invasiveness, as such platforms (Apple already does) use age of account as a proxy and never check more. Younger users get no such benefit. good for data minimisation, but keeps people in a bubble.

I'm not joking when I say mRNA technology is more important than "AI" and it's a tragedy we're throwing billions into one while our government is aggressively defunding the other.

New BMJ Editorial out today from @rocher.lc and me: www.bmj.com/content/393/... - Biobank's response to the news that researchers have accidentally uploaded data to GitHub multiple times is insufficient & risks trust in the UK's health data ecosystem. Everyone needs to feel responsible for privacy.

We warn that institutions must demonstrate humility, a commitment to listening to privacy experts, and a willingness to learn. As the govt bets on health data and AI in its 10y health plan, which commits to making the NHS “the most AI-enabled health system in the world,” time is running out.

UK Biobank DMCA Tracker Tracking DMCA takedown notices filed by UK Biobank against GitHub repositories where researchers accidentally published participant health data.

After the Guardian successfully re-identified a participant from two pieces of data, UK Biobank has sought to downplay the importance of this exposure, stating that the data posted to GitHub are “de-identified”. This term has no legal meaning in the UK.

Here's the map with 1/3rd of the votes counted. Tisza = blue; Fidesz = orange. The strength of the color tells you how far ahead the lead party is. It's a blow-out. Fidesz strongholds are falling to Tisza.

LSE: We’ve filed a case over their investigation into sexual misconduct | Good Law Project The university fumbled their response to a series of complaints over sexual misconduct – so we’re pushing back

"When five women made formal complaints of sexual misconduct against a senior professor at the LSE, the university carried out a botched investigation and kept him in post."

"We’re supporting one woman as she takes action over the way they bungled her complaint."

Thanks @emollick.bsky.social! We found that older generations of models already did well on benchmarks and very simple evaluations, but fared poorly in conversations.

The obvious takeway is that evaluating AI models is not easy and cutting corners results in poor, harmful evaluations of risks.

Too many students are convinced by their own universities, by some of their teachers and professors, and by the AI companies themselves that ‘using ai to study is getting ahead of the game’
But the process they seek to get ahead of is the point.

Confidential health records from UK BioBank project exposed online Exclusive: Guardian investigation finds data from flagship medical research leaked dozens of times

UK Biobank records on hundreds of thousands have been exposed online, and will keep being exposed as students and researchers accidentally re-upload data.

I reviewed several of these datasets for The Guardian and can attest to the severity of the data exposed.

Anonymization: The imperfect science of using data while preserving privacy Safe anonymization and sharing of personal data will be achieved by combining formal privacy methods with red-teaming.

Colleagues and I have spent years showing that stripping names or addresses isn't enough to protect privacy. It seems like lessons are not being learned, which means public health research will continue to suffer from a genuine lack of trust.

It's nearly impossible to go through life without sharing details like a birth date or a workplace injury. Just this could identify a colleague or neighbour in UK Biobank data. Once identified, their records could reveal a psychiatric diagnosis, an HIV test result, or a history of drug abuse.
