Very lucky to have @jamiecummins.bsky.social as a STAR editor at Psych Science, helping us navigate these kinds of issues. This is such important work.

Can large language models stand in for human participants?
Many social scientists seem to think so, and are already using "silicon samples" in research.

One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.

The threat of analytic flexibility in using large language models to simulate human data: A call to attention
Social scientists are now using large language models to create "silicon samples" - synthetic datasets intended to stand in for human respondents, aimed at revolutionising human subjects research. How...

Another chapter in the book of “Sometimes There’s Nothing There & Using Fancy Stats to Find Something Can Be a Bad Idea”

Do you wish we could understand causality by finding lagged effects in longitudinal data?
Bad news - lagged effects are probably rare, & even the RI-CLPM is an ill-suited test.

Interested in models used to estimate lagged effects in panel data? We (@rebiweidmann.bsky.social, Hyewon Yang) have a new paper looking at patterns of stability and their implications for bias and model choice: osf.io/preprints/ps... [1/x]

We speak to @simine.com, @wchiggins.bsky.social and Laura Conlon about MetaMelb. This lab studies what is essentially ‘the psychology of psychology research’ – examining practices and norms across psychology.

If I’m understanding right, Aaron Clauset at Peer Review Congress showing that the strongest correlate of peer review outcomes at Science and Science Advances is the prestige of authors’ institutions. Also pretty big association with author geography, not much with author gender. #PRC10

At the Peer Review Congress #PRC10, @maclomaclee.bsky.social talks about flaws in meta-research. Often only points out problems, doesn’t test solutions, & often uses suboptimal methods (observational design, convenience samples).
Great points, but imo, pointing out problems can be big contribution.

A meta-perspective by Malcolm Macleod on the presentations at #PRC10.

Are we going for low hanging fruit too much in research on peer review / publication?

Michael was my undergraduate thesis advisor. I have been moved to write some reflections on his life, and my time with him open.substack.com/pub/alexholc... #visionScience A hashtag seems gauche, but Michael should be more widely known - he didn't attend conferences much.

Yikes. My blog is on Typepad. I have one month to rescue it. Any tips on what I should do? I’d like to keep it active (not just back it up, but host it somewhere else in case I ever get around to writing more posts). I’d love recommendations, esp ones that require little/no technical skills 😂

A letter to the editor from @alexh.bsky.social et al. about an error in a published paper led to retraction. Great to see the record corrected, but also raises tricky issues about what the right form of correction is, how to credit the error detectors, and how to reduce future chances of same error.

“This simple experiment gives objective evidence for Stroud’s perceptual moment theory.” It does no such thing, and now, the article has been RETRACTED.

We called for its retraction in a letter we wrote to the Attention Perception & Psychophysics editor in 2023, and now posted on PubPeer.
RETRACTED ARTICLE: Insights into the perceptual moment theory: Experimental evidence from simultaneity judgment - Attention, Perception, & Psychophysics
The perception appears to flow in a continuous pattern but evidence suggest that perception may involve discrete temporal sampling of peripheral cues. Stroud’s perceptual moment theory proposes that p...

I know it’s gauche to share good news on here, but our university’s IRB (ethics office) just declared that low risk applications will no longer be reviewed by 4 people & then go to a committee. They’ll be reviewed by 1 person.
I almost can’t believe a change this positive is possible in this world.

"Preregistration" lumps three distinct practices into one:

- Study registration
- Protocol
- Analysis plans (SAPs)

To advance open science, it's critical that we distinguish them.
