You must be tempted to tell the story like this: phil. sci. and the core of analytic epistemology drifted apart; things got so bad that the residual "core" started to see "inquiry" as largely unstudied; by turning back to science we can set the record straight and solve the allegedly new problems.

Abundant Eocene fossils of plants and animals are found in the Green River Formation of Wyoming, Colorado and Utah. This fossil Pseudosalix Hanleyi, with stems, leaves and flowers preserved, is harder to find than a T-rex tooth!

This thread shows the extraordinary work that the Patient-Led Research Collaborative (working on Long COVID and other infection-associated chronic conditions) has done, incl. scientific work that has challenged and massively improved the research that people without Long COVID do on the disease 1/
Thank you to everyone who made our work possible this year! Here's a thread on some of the highlights from PLRC's research, advocacy and education efforts in 2025.

All of this work is carried out by a team living with #LongCovid 🧵 /1

In our latest, we look back at 2025, a year where normalization slipped into naturalization, as a cadre of villains who rose to prominence on the back of covid denial took the reins of the federal government to play out their revenge fantasies.

It’s Covid Year Six.

In my new paper, I argue that conditionalisation, qua rule of inference, cannot be justified independently of the priors.

In a nutshell, the argument is this. Conditionalisation says: stay as close as possible to your priors! This is good advice only if your priors are good priors

Great comment from @jefflubellc19.bsky.social in @annfammed.bsky.social.

He argues for the value of patient and caregiver observations and hypotheses, saying journals should publish more case studies and hypothesis papers from those groups.

Feat. @patientled.bsky.social!

This trial enrolled this many participants this quickly because it’s designed to meet the needs of people with Long COVID, and it’s this well designed because it was designed by the amazing @julialmv.bsky.social who lives with Long COVID herself

Patient participation in research is essential

500 enrollees in *less than two weeks*! So many clinical trials would take months, or even years, to enroll this number of people.

This is what happens when you plan a trial that meets participants where they are, is not overly onerous, and tests something people think is worth trying.
Our randomized, placebo-controlled trial of tirzepatide (Zepbound) for #LongCovid has already enrolled 500 participants of 1000 planned in less than 2 weeks!

LoCITT-T trial was covered by Wired today:

My comments include:
"For the long Covid population...if you’re requiring people to come into a clinic, you’re systematically excluding the most severely affected folks who are housebound or bedbound."
Weight-Loss Drug Zepbound Is Being Tested as a Treatment for Long Covid
GLP-1s are being studied for a wide range of conditions. Now, scientists will test whether their anti-inflammatory properties can help alleviate symptoms of long Covid.

I’d be grateful if more were written on RFK’s AIDS denialism—important context IMO when we hear him say things like, Long Covid docs are being ignored like docs were ignored in the AIDS crisis. I think he’s dog-whistling alternative therapies that posited lifestyle and not HIV caused AIDS.

This is why pwME get so upset when newcomers to the field don’t engage existing experts. We have lost so, so much time, and critical information, to people who refuse to build on existing knowledge.

Every now again it’s useful to repeat advice about accessing papers that are behind a paywall that excludes you. Email the author. My estimate is that 90% of academics are so thrilled that a living, breathing, possibly even reading, person shows interest that they will swiftly send you a copy.
