ANSWER: 0 (yes, ZERO!) This is a result of an analysis done by a student in my grad seminar, using a large dataset (N=307,313). What this result might mean: Nobody's personality is truly "average," and people's personality profiles (at least Big 5) might be more "jagged" than we think. (🧵 1/5)

As part of the Pilot Reporting Task Force, founded at @improvingpsych.org conference 2023, I would like to share a preprint with you: osf.io/preprints/ps.... We are looking for feedback on our perspective piece, promoting more transparency in the reporting of piloting in psychological science. 1/4

"Don't seat the baby near the door" 👶 Thanks to @infantstudies.bsky.social for the chance to discuss our task force work on making pilot study insights more transparent to improve psyc science! @agataboch.bsky.social #OpenScience #DevPsySky #PilotStudies #PsychScience #Transparency

For those interested, here's our full preprint on the call for more transparent pilot study reporting: osf.io/preprints/ps... @ihandleyminer.bsky.social #OpenScience #PilotStudies

New 📰 Demand characteristics are a fundamental methodological concern in research with humans Yet little is known about the magnitude and consistency of these effects In a new paper, I, M. Wyatt, and @mcxfrank.bsky.social take stock of what we’ve learned via meta-analysis doi.org/10.1525/coll...

Funding opportunity for SIPS members! The Society for the Improvement of Psychological Science and Peer Community In Registered Reports invite researchers to submit research projects for consideration for research funding from SIPS and a recommendation decision from PCI-RR. buff.ly/AigqCod

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

I'm working on PaperCheck today, and would love to take queries about whether it could do something you'd like to accomplish more easily in your metascience workflow. I'll try to show you how, and maybe even get you to collaborate on adding a module! scienceverse.github.io/papercheck/

Many-analysts approaches can help uncover analytical insecurity. The Journal of Robustness Reports publishes short reports that check alternative analytical approaches for articles. Very cool! 💪 #SIPS2025 @improvingpsych.org #OpenScience

We're back, with a fresh new lineup of talks and workshops! Get your place while you still can to learn about how to make your research more robust and how to deal with scientific fraud! This event is free and open to all: tinyurl.com/3ewaduvm

My editorial on how journals can earn trust. We often use journal names as proxies for quality. This is bad bc it’s not valid. But it could be. Editors could make journal name a valid signal. And we could place value on journals that show us how they do that. journals.sagepub.com/doi/full/10....

What is the future of Open Science? Join @annemscheel.bsky.social @nicholascoles.bsky.social @szaszibarnabas.bsky.social @aufdroeseler.bsky.social and @stephaniemlee.bsky.social for an exciting discussion during the Keynote Panel at the #SIPS2025 Online.

🔬 Want to improve research transparency? Join this webinar with experts from @plosbiology.org! Learn how this format enhances reproducibility & benefits science. 🎤 Dr. @npariente.bsky.social & Dr. Nikki Osborne from @rrr-research.bsky.social 📅 April 30, 3 PM CEST #OpenScience

Some nice new papers hitting the AMPPS website-- check 'em out! @psychscience.bsky.social

If you want scholarly publishing to be more aligned with scholarly values, then try out Lifecycle Journal. If you embrace transparency, then you can do your research in the Lifecycle Journal without risking publishing in the existing system if you later decide to do so. A🧵 lifecyclejournal.org

In the latest blog of the Meta-Research Center, I wonder if meta-scientists should hold themselves to higher standards. Do we lose credibility if we don't always follow all best practices we advocate for? #metascience #statcheck #psychscisky metaresearch.nl/blog/2025/3/...

An excellent investigation highlighting the value of sharing code, in addition to data, for establishing reproducibility.

🚀Very excited to finally see our paper on nonsignificance misinterpretations published! 📈 Together, @smurphee.bsky.social, Aurelio Fernández, Linda Reimann and I investigated the prevalence of "p > .05 = absence of an effect" interpretations. (1/4) doi.org/10.1098/rsos...

I can't really see any downsides to sharing code -- it's very simple and many concerns that apply to data sharing don't apply at all -- so I really hope we can get that number up all the way, until it's just a no-brainer.

How can we reduce conceptual clutter in the psychological sciences? @ruimata.bsky.social and I propose a solution based on a fine-tuned 🤖 LLM (bit.ly/mpnet-pers) and test it for 🎭 personality psychology. The paper is finally out in @natrevpsych.bsky.social: go.nature.com/4bEaaja

After a long wait, the working paper for the Many-Economists Project: The Sources of Researcher Variation in Economics.

Visual Analogue Scales are often used to measure short-term changes in body dissatisfaction. But how much change (out of 101 points) represents a meaningful change? 20 points? 10? 5? In our new (open access) paper, we try to find out: www.sciencedirect.com/science/arti...

After my first year as EiC of Collabra: Psychology, I wrote an editorial with my reflections so far. Featured are some observations about submission triage, author geolocation data, and a registered revisions experiment. @collabrapsychology.bsky.social @improvingpsych.org doi.org/10.1525/coll...

We love to share new papers on here. But how many of the studies that scientists preregister on the Open Science Framework are never shared publicly? In a new paper in AMPPS we estimate 40% of preregistered studies are never shared. That’s a lot. journals.sagepub.com/doi/10.1177/... 🧵⤵️

It’s insane that I got all the way through getting a PhD before I encountered equivalence tests. These should be part of every intro stats curriculum that covers NHST.

If you are a psychology researcher, please consider taking this survey about pilot studies: research.sc/participant/... Our team is hoping to learn how researchers approach the process of piloting. 20 randomly chosen participants will receive $50 gift cards! #PsychSciSky #MetaScience #OpenScience

The Lifecycle Journals project will test a publishing model that aligns rewards with research rigor and transparency. If it works as hypothesized, it should: * engage review across the lifecycle * facilitate self-correction * diversify rewards for authors and reviewers www.cos.io/lifecyclejou...

I would want that coding disclosed in a prereg so that I can try and replicate this in the future. I helped put together the secondary data prereg as well. I want to know the decision-making process for all studies--so I can replicate and also understand the reasoning behind choices.

There are two critiques in the Science Magazine story of the prospective replication project that are worth taking seriously. A short thread... www.science.org/content/arti...
