This is how science actually works. It’s less the parade of decisive blockbuster discoveries that the press often portrays, and more a slow, erratic stumble toward ever less uncertainty. Our understanding oscillates at first, but converges on an answer. 1/ theatlantic.com/health/archive… This is how science actuall...
There’s a lot of expertise around, but fewer tools than ever to distinguish it from everything else. Pure credentialism doesn’t always work. People have self-published terrible pieces on Medium, but some of the best early explanations for laypeople were from tech guys. @zeynep 2/ We hunger for information, ...
The issue is that modern expertise tends to be deep, but narrow. But pandemics demand both depth and breadth of expertise. No one knows it all, and those who claim to should not be trusted. @edyong209 3/ The issue is that modern ex...
The pandemic's length traps people in a liminal space. To clarify their uprooted life & indefinite future, they try to gather as much information as possible-and can't stop

Pandemics actually unfold in slow motion & there's no event that changes the whole landscape on a dime 4/ The pandemic's length traps...
“Journalists still think of their job as producing new content, but if your goal is public understanding of COVID-19, one piece of new content after another doesn't get you there. It requires a lot of background knowledge to understand the updates" @jayrosen_nyu 5/ Rosen also argues that the ...
Case counts don't show how many people have been infected on any given day. They reflect insufficient testing, reporting lags, and false negatives. 6/ Those numbers do not show h...
"I think people underestimate how difficult it is to measure things. For us who work in public health, measuring things is like 80 percent of the problem." @nataliexdean 7/ The numbers still matter; t...

Friends with no previous interest in AI ethics have been asking me about it recently, so I want to share several underlying concepts about AI & power that are important to understand. 🧵 1/
AI and Power: The Ethical Challenges of Automation, Centralization, & Scale

Based on 20-min talk:

Blog post version: rachel.fast.ai/posts/2023-05-…
2/
In Australia, automation was used to scale putting poor people into debt (often illegally). The govt went from creating 20,000 new debts PER YEAR to creating 20,000 new debts PER WEEK, many of them bogus, but hard for people to appeal. 3/

Viruses: The Silent Triggers of Autoimmune & Neurodegenerative Diseases (how a simple cold can lead to life-changing disease) 1/

My new post: rachel.fast.ai/posts/2023-03-…
Rheumatoid arthritis, Crohn's disease, Multiple sclerosis, Type 1 Diabetes, Lupus, Hashimoto's, & Psoriasis impact a range of body systems, but all are autoimmune diseases.

Developing a lifelong autoimmune disease is often first triggered by an infection. 2/
Medicine is very siloed, and autoimmune diseases have often been treated in separate silos, based on which body system they impact, limiting our broader understanding of common threads. 3/

Even common viruses can have long-reaching, surprising, & devastating consequences. Fortunately, there are simple steps we can take to reduce transmission. 1/

My new post: rachel.fast.ai/posts/2023-03-…
The idea that a common childhood virus can quietly hang out in your nervous system, reactivate decades later to cause shingles, and then months AFTER shingles blisters clear up cause blood clots & strokes is mind-boggling to me 2/

theconversation.com/chickenpox-and…
VZV (chickenpox virus) is not just linked to strokes, but also linked to multiple sclerosis or vascular dementia (my note: possibly through reactivating other viruses).

Numerous common viruses increase risk of Alzheimer's or Dementia. 3/ cell.com/neuron/fulltex…

After 12 years working as a data scientist & AI researcher, I have gone back to school for a Masters in Immunology. When I become fascinated by a topic, I want to learn as much as I can. 1/

rachel.fast.ai/posts/2023-02-…
My ultimate goal is to apply my machine learning & data ethics skills to immunology, but I want to make sure I fully understand the underlying domain & relevant context first. (With ML, it’s important to not just be a hammer searching for a nail). 2/
Immunology is a complex and vast field, full of open questions and not-yet-fully-understood phenomena.

Viral infections have been significantly associated with many neurodegenerative diseases, including Alzheimer’s. 3/

I made a mastodon account a few weeks ago: @math_rachel@mastodon.social (in case twitter falls apart)

I haven't used it yet and have mostly been taking a social media break prior to this. 1/
I used to post a lot on twitter (about machine learning, working in tech, algorithmic harms, & later covid). I loved this place and I learned a lot from others here. Thank you to those I met & learned from. (I plan to stick around, but who knows what will happen.) 2/
Being high-risk during an ongoing pandemic, not being able to safely access healthcare, seeing how many people I used to respect are going along with the erasure & destruction of disabled people-- all this has shattered my previous worldview. 3/

This is a thorough, incredibly well-researched explanation of the Qld government's unscientific & unethical pursuit of a "wall of immunity", which was doomed to failure before it had even begun. by @ColinKinner

Please watch the embedded video of Chief Health Office Dr. Gerrard. Note that when he repeatedly says that it is inevitable & necessary for us to all catch covid, he is speaking as someone with significant political power. 2/ Photo of Dr. Gerrard at a press conference, wearing a white Photo of Dr. Gerrard at a different press conference.

Messaging from @qldhealth continues to focus on social distancing & hand-washing, even now in 2022.
