Getting nervous for the talk I'm about to give at a workshop about "using AI to drive impact" which features slides such as these.

@srhastraea.bsky.social is a humble & busy guy so the aussie will announce his successful #marsden Unpacking how we choose who to trust for knowledge in complex, contentious issues with the potential for misinformation @scicomguy.bsky.social @matthewmatix.bsky.social @rachelprozac.bsky.social

Are you interested in thinking about which studies are worth replicating? Then you have 10 articles to dig into in Meta-Psychology, representing a very wide range of viewpoint on this topic, out now: open.lnu.se/index.php/me...

We built the openESM database: ▶️60 openly available experience sampling datasets (16K+ participants, 740K+ obs.) in one place ▶️Harmonized (meta-)data, fully open-source software ▶️Filter & search all data, simply download via R/Python Find out more: 🌐 openesmdata.org 📝 doi.org/10.31234/osf...

Extremely pleased to see this work published! Thank you so much to my excellent collaborators @fmsmallfield.bsky.social @scicomguy.bsky.social @srhastraea.bsky.social @lingtax.bsky.social @mdmarques.com @matthewmatix.bsky.social onlinelibrary.wiley.com/doi/10.1111/...

Papers from July to Sept 2025 at AMPPS are killer. We don't have formal print issues, but we have this-- journals.sagepub.com/toc/ampa/8/3

The existential threat model suggests stress & anxiety can lead to belief in conspiracy theories. And prior studies have showed they are *correlated* with belief in CTs. But do they *cause* belief in CTs? Find the answer here... (Or apply Betteridge's law of headlines, if you're pressed for time)

Results of the replication are in! Chocolate is more desirable than poop: Cohen's d_rm = 6.20, 95%CI [5.63, 6.78] N = 486, two single item 1-7 Likert scales of desirability. w/ @jamiecummins.bsky.social

I think words are valuable when they describe some things but not others.

Should statistical software that estimates causal effects also tell you the causal assumptions under which that estimate can be interpreted as causal? I don't know but my PhD student Maurice Korf has some thoughts (and software) to get the conversation going: academic.oup.com/ije/article/...

PCI Psychology is open for submissions! Did you know that you can easily submit your recommended preprint to any of the 20+ PCI Psych friendly journals? See all friendly journals here: psych.peercommunityin.org/about/pci_fr... #PsychSciSky #SciPub

My article "Data is not available upon request" was published in Meta-Psychology. Very happy to see this out! open.lnu.se/index.php/me...

Excited for my doctoral research to be published, thanks to the support of @matthewmatix.bsky.social @srhastraea.bsky.social

I'm joining the brilliant @jkarl.bsky.social as co-EIC at Europe's Journal of Psychology. ejop.psychopen.eu/index.php/ejop EJOP is a generalist psych journal, and applies a diamond open access model (no APC). I'd love to see more submissions with rigorous methods & well-calibrated conclusions!

PhD holder who didn't collect any original data for my thesis checking in 🙋 The world isn't short of data to analyse! (I did collect data for my Masters... pen-and-paper surveys from primary school kids... back in the olden days!)

Some researchers don't discuss their future research plans for fear of being scooped. Not me. I drop bad ideas for unscrupulous people to 'steal'. - What are the neural correlates of Open Science practices? - What is the role of habits in learning a new skill through repetitive practice?

BEWARE: Surveys that allow anyone to "opt in" are vulnerable to those who create many accounts (using VPN to bypass IP limits) & use automated tools to generate bogus responses (such as saying "yes" to question about being licensed to operate nuclear submarines). www.pewresearch.org/short-reads/...

PsyArXiv's amazing team of 100+ moderators has now approved all preprints that meet the requirements outlined in the updated PsyArXiv policies (is.gd/paxpolicy). Thank you to everyone who volunteered, this was a true community effort! #PsychSciSky

If you have submitted a preprint to PsyArXiv in the last year or so and it *isn't* currently accessible, there's a good chance it's due to the document listing authors whom you haven't entered in the metadata.

Great list for all kinds of claims, not just autism.

PsyArXiv is now down to only ~40% of the backlog we started with, thanks to our amazing moderators 🎉 To all mods: thank you so much for your hard work! Did one of your preprints get approved recently? Help us show our thanks by liking and sharing this post :) #PsyArXiv #PsychSciSky

Papers often conclude "more research is needed" without explanation. This is a missed opportunity. You are the expert. This is your time to shine. Explain what the remaining uncertainties are, and give justified recommendations on what the research needed to resolve them should look like.

It's blimming awesome that AMPPS is a PCI RR -friendly journal. @pci-regreports.bsky.social The peer reviews for this paper were impressively rigorous and constructive; one of the reviewers even suggested code for an improved analysis. I'd love to see more journals become PCI RR friendly.

I love @peercommunityin.bsky.social because it gives the best of both worlds. Peer review is free, public, and relatively quick (especially if you use PCI-RR's scheduled review). It's then up to the authors whether to publish diamond OA or pay APCs to publish in more prestigious journals.

If researchers find Cohen’s d = 8, no they didn’t. (probably.) Thoughts on the distribution of Cohen's d values in psychology and why we should think about their plausibility when reading articles.

"In particular, it seems reasonable that, at a bare minimum, senior management should not systematically and rigidly pursue a philosophy and policies that harm the institution and the community who make it up." Damn, does this resonate.

it's wild that R, the ubiquitous statistical computing language, was co-created by a Māori prof (Ross Ihaka) — and yet the vast majority of scientists who use R don't know this is like inventing the toaster. possibly the largest impact of a single member of an indigenous community on modern science

In February 2024, I wrote Scientific Reports about a published meta-analysis claiming that mindfulness interventions affect neural plasticity, 'cementing the neuropsychological basis of mindfulness-based interventions'. The paper was retracted yesterday—here a little summary of the process.🧵

Friends, if you say that one thing "fosters" or "fuels" or "leads to" or "impacts" or "produces" some other thing... you are making a claim about causality.

Fun party trick: open a paper that strongly implies causality in the title, [CTRL + F], search for “causal” and read all hits.

I think it is a mistake to think that if we cannot detect then we cannot forbid. Fraud & plagiarism are forbidden. Often they may go undetected (like people may drive too fast or through a red light), does not mean they are not violations of scientific integrity (or law, in case of the examples).

EMDR didn’t do that: Inconsistent numeric findings in Gauhar (2016) osf.io/preprints/ps... In which I discuss how an RCT that claimed an enormous effect of EMDR on depression (d = 1.97) includes statistics that should not be possible given the sample sizes and scale types.

New blog post! Let's say you've measured two variables repeatedly and want to investigate how one affects the other over time. Here are some recommendations for how to do that well. www.the100.ci/2025/06/25/r...

A few months ago, Nature published how-to guide for using ChatGPT to write your peer reviews in 30 minutes. This is, of course, a horrible idea. Here’s my response with @jbakcoleman.bsky.social .

This is bad news for editors at Wiley journals. Editors at PCI RR friendly journals don't have to burn as much time searching for reviewers, since PCI recommenders shoulder that duty (and do an amazing job). But thanks to Wiley you may now find it even harder to secure reviewers than it was before..

Springer-Nature launched a series of "Discover" journals that closely mimic MDPI titles -- sharing *identical* journal names, and likely similar business model. What is going on, and why researcher will - as always - fall for it? A 🧵 the-strain-on-scientific-publishing.github.io/website/post...

Every week I'm reminded of how measurement, statistics, design, bias and error are so often treated as sidecars to "the science" in clinical research. It seems like the funders are coming around on this, which is great. Will institutions respond by investing in methods expertise?

I’d like to take this one step further: poor communication & hype often already start in sci papers. “Because this study was only observational, no causal conclusions can be drawn” followed by a discussion of policy implications and theorizing based on a causal conclusion.
