Telling article on #AIEthics (yep, that’s irony 😆) which among its many contributions explains why people (eg comp sci but also physicians!) can brand themselves as “AI ethics experts”, going so far as to give talks, provide “advice,” even run academic courses! theintercept.com/2019/12/20/m...

How Big Tech Manipulates Academia to Avoid Regulation

“AI ethics” is a field that barely existed before 2017. It’s become a Silicon Valley-led lobby to avoid legal restrictions of controversial technologies.

Cool cool. This forced social experiment is certain to end well. Anybody know the DSMB we can talk to? 😩

'Research published...in Science suggests that receiving excessive approval from artificial-intelligence systems could encourage uncouth behaviour.....participants who received highly flattering feedback from chatbots tended to be more certain of their own correctness during social conflicts'. 1/2

What is a silent evaluation in #HealthAI ? And how do you do one? 👀 check out our new paper! We performed a scoping study re published practices in silent evals for AI/ML tools - everything from hospital-based prediction algos to regulatory-approved medical devices www.nature.com/articles/s44...

it is worth remembering that cigarette companies also spent decades selling products they knew would harm and kill people and marketed them specifically to young people to create dependence. let's stop this without having to go through a generation of death and several class actions.

1.This is not the only known example we know of ChatGPT cheering on a vulnerable young person to die by suicide, this time it is a recent Texas A&M grad 2. Every single university that has invited OpenAI into our midst should be asked to account for their choices. www.cnn.com/2025/11/06/u...

Shamblin’s conversation partner wasn’t a classmate or friend – it was ChatGPT, the world’s most popular AI chatbot. A CNN review of nearly 70 pages of chats between Shamblin and the AI tool in the hours before his July 25 suicide, as well as excerpts from thousands more pages in the months leading up to that night, found that the chatbot repeatedly encouraged the young man as he discussed ending his life – right up to his last moments.

And the fact that they even think this is possible shows they have absolutely zero understanding of any concepts and principles related to “bias” 🤨 If they cannot understand the very concepts they invoke, then they have zero credibility to address the problem and should sit this one out.

Luke Steuber@coolhand.bsky.social · 10mo ago

We took every personal, cultural, and institutional bias in our language and baked it into the foundation of this tech. I would say good luck with that, but they know damn well this is marketing People don’t get that their output is derived from *us.* It’s not just biased, bias is in its genes

I've yet to see a single discussion of "Canadian digital sovereignty" include any Indigenous experts, at best we're given a token mention that at some point they'll "consult with Indigenous Peoples" like we're some sort of monolith. Umm, y'all need to consider all our lands, and our distinctiveness.

Turns out that #Google was publicly logging ChatGPT conversations that people had shared (privately, or so they thought) with friends. There are conversations about mental health, sex, etc. Do you still think #OpenAI take #privacy seriously? By @stokel.bsky.social fastcompanyme.com/technology/g...

Google could be reading your ChatGPT conversations. Concerned? You should be

Thousands of shared ChatGPT chats are now appearing in Google search results.

I have seen this!! We tested some models with dummy data and found that someone calling someone or something “deadly” was ALWAYS coded as negative sentiment (it’s the opposite!) We ended up deciding the sentiment function will be useless and scrapped it.

A new study shows large language models find it much harder to understand the nuances of Indian, British and Australian English.

It was so much fun chatting to @dsilvaphd.bsky.social on SHE Pod about all things #AIEthics! We chatted about a recent paper I wrote with Mjaye Mazwi and Lauren Oakden-Rayner where we asked, when is an accurate model a bad thing? And why? www.cell.com/patterns/ful...

Can an accurate model be bad?

Outcome-prediction models can harm patients even when they have good accuracy, as shown in a recent Patterns paper by Van Amsterdam et al. In this preview, we consider the ethical and empirical implic...

🥳 New SHE Pod is up! This episode, I chatted with the awesome and funny @mdmccradden.bsky.social about #AI, #bioethics and whether we can have too much diagnostic precision (and what would that even look like). We also talked about the potential of bioethics whitewashing re: AI hype/reaity.
