The worse part though is that as their costs go up for adding these nonsense features, they inevitably offload it onto us, the consumers. 😡 I’m now looking into old school options again to get away from this stuff.

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.

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
OpenAI is trying to clamp down on ‘bias’ in ChatGPT
GPT-5 is better at resisting liberal ‘pressure,’ the company says.

Not arrogant - 100% accurate. The very fact that these folks can switch up their buzz words on a dime shows they don’t understand the words in the first place.

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.

We’ve also pre-registered our study on OSF to encourage transparency and sharing with the scientific community

This is a feasible, generalizable approach to evaluating commercial scribe tools to make an informed decision about where they fit (and don’t fit) & building clinical procedures to share the accountability between physicians and their health institution

Do you know what I find wild tho? Nearly a decade of being an ethicist - raising concerns, questions, challenges in a plethora of contexts has been my job. This is different. I’ve never felt so at risk personally for doing this as I do for LLMs. People get personally offended, get nasty even.

“is it just everybody is scared to say this and pleased I did?”

^^^* YES, we are!!!

Hey #AIEthics people (and all people as well!), got a question for you…

Is anyone else 100% completely and totally fed up with AI ethics?
mdmccradden.bsky.social
I think it’s kinda fascinating to see the epistemic struggle in this write-up between the beliefs espoused about LLM “capabilities” versus the considerations re ethics violations… 🤷🏼‍♀️

I hate that I believe you are 100% correct on this prediction 🫠
mdmccradden.bsky.social
Always stunning how the scientific standards for study designs and the claims one can make from them get thrown out the window when it involves AI. Any study that is not longitudinal is meaningless given we are now seeing the long term effects of AI use = worse learning and performance.

I will believe AI has PhD-level knowledge when every response is concluded with a suggestion of a local seminar or talk that has free food 🍕☕️

Our preprint is up! Ever heard of the silent phase of AI evaluation for medical AI? Well, now we’ve summarised the current state of research!
mdmccradden.bsky.social
We are also SO excited to release our preprint for our scoping review reporting on current #silenttrial practices for #HealthAI

@lanatikhomirov.bsky.social did an amazing job leading this work all the way through ❤️

Please get in touch if you do or are interested in the silent evaluation phase - we want to hear from you!

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

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.
‘Are you joking, mate?’ AI doesn’t get sarcasm in non-American varieties of English

I have also wondered whether using the common name (eg ChatGPT, Gemini) in papers (esp titles) instead of the actual model name/version is like using the brand name of the drug rather than the substrate… probably not gonna look good down the line
