2025 update because I'm not seeking to hire anyone or sponsor any new students right now. Possible exceptions for people who are *really* allied with my funded work (e.g., on mpox vax, vax misinfo) and/or have access to external funding (e.g., fellowship, home nation). Lab is at capacity for now.

Prospective students: Here's what you need to know if you think you might want to work with me (a thread):

1. I'm not looking to recruit new students at the moment. (There could be some exceptions, especially for research-oriented Master's students in my school or interdisciplinary studies.)

Yet another study finds vaccination associated w lower odds of persistent post-Covid conditions (PCC), even after mild Covid. New Thai study looked at impact of mRNA vaccination on PCC after mild cases; found vaccination is protective & 3 doses were better than 1. doi.org/10.1016/j.va...

Wildly different things, tasks, techniques, subspecialties being lumped into "AI" and then being conflated with each other, doesn't help. Different types of models vs the techniques to train them vs the tasks they are supposed to accomplish, all under "AI".

The first few weeks in Canada were confusing. Need an air mattress until your bed arrives? Go to the tire store. Left your computer cord behind in the move? Go to the drugstore. *Obviously* 🤷🏻‍♂️

Do you know if there is individual- or community-level association between consumption of conspiracy media (X-files, Matrix, etc.) and involvement in contemporary, more threatening, conspiracy movements?

Devon Greyson @greyson.bsky.social · 5d

Yeah. As someone who was kind of raised on conspiracy theories (that seemed harmless, like Kennedy assassination & UFO stuff), I miss when conspiracy theories were fun. I wonder a lot about the turn that led to violent action as response rather than intellectual delving into archives etc.

I have heard of senior authors who didn’t realize their coauthors to whom they delegated writing the lit review, for example, were using genAI (& didn’t even realize to ask). So I am not advocating for super harsh lifetime bans. But enough to incentivize attention seems necessary.

Devon Greyson @greyson.bsky.social · 6d

And don’t even *start* suggesting that so-called “AI” is the solution to the peer reviewer shortage.

That way lies recursive model collapse; the last thing we need in science today.

Devon Greyson @greyson.bsky.social · 6d

In my worldview, yes. While it is possible to use (some) LLMs in writing in ways that are not misconduct, sloppy GPT type trash is not it. I honestly don’t know why journals give so much grace to academic bad actors.

Devon Greyson @greyson.bsky.social · 6d

Many forms of writing using LLMs are plagiaristic, but not all. However, flirting w plagiarism while also wasting editor/reviewer time, in our current crisis of reviewer availability, w machine-generated fast trash is certainly unethical, and no journal/publisher owes such “authors” their attention.

Devon Greyson @greyson.bsky.social · 6d

I’ve said it before & will again: wasting editor & reviewer time by submitting egregiously plagiaristic uses of genAI w/o even fact-checking should be grounds for being barred from submitting articles to that journal for a period of time (1-2y for first offense?)

I’m sorry, but it is disgraceful to be an academic who uses this technology to conduct research. It should be prohibited in all of our scholarly institutions, including universities and journals.

Given the context-specificity of vaccination schedule recommendations, I hope he’ll also be recommending the Danish universal welfare system, including high minimum wage, gender equality, paid parental leave, subsidized childcare, state retirement pension, no-user-charge universal healthcare, etc.

RFK Jr. is expected to announce in the new year that American children should be immunized according to the schedule followed by Denmark — which is much smaller, mostly homogenous and has universal health care.

To be clear, evidence based practice has significant limitations as it has been practiced to date. But those limitations have largely to do with the evidence base and the lack of diversity in professions, not the basic idea that scientific evidence matters as much/more than individual views.

Devon Greyson @greyson.bsky.social · 10d

The gutting of peer scientific review, more broadly, is about the deconstruction of expertise and traditional scientific metrics of credibility. Trying to lower the curtain on the era of evidence-based practice.

Mark Histed @markhisted.org · 10d

Well, this is an utter disaster for science.

This gutting of peer review is very likely driven by Project 2025/OMB/Vought, very likely is about funding junk science, and very likely is coming for #NIH and biomedical research next.

NEWS: NIH will pause new funding for grants that include "misaligned" terms like "health equity" and "structural racism."

Agency staff are required to use a "computational text analysis tool" to identify grants that include the unsanctioned terms.
