📣 PSA I've been wanting to say for a while. Not everyone is an expert programmer or coder, and that's okay. People can still do good, reproducible research without using the fanciest methods or the coolest tools. Low tech tools ≠ You can't do good work

At the FORRT Replication Hub, our mission is to support researchers who want to replicate previous findings. We have now published a big new component with which we want to fulfill this mission: An open access handbook for reproduction and replication studies: forrt.org/replication_...

If you are preparing your bachelor statistics course and would like to add optional material for students to better understand statistics on a conceptual level (see topics in the screenshot) my free textbook provides a state of the art overview. lakens.github.io/statistical_...

thrilled that our guides for #OpenScience in developing countries is now published in AMPPS of @psychscience.bsky.social: journals.sagepub.com/doi/10.1177/... Please see the thread for details

🌍 Glad to see our paper out! How researchers in developing countries & other resource-constrained contexts (can) practice #OpenScience, with free tools, training, success stories, & more. 🔓 doi.org/10.1177/2515... 🛠 osf.io/gu7v4 More in this thread by @hcp4715.bsky.social 👇 #AcademicSky #PsychSky

🌱 Let's dream of better OS communities together! 🌱 Nominate yourself or someone else here: forms.gle/vNwrUWvkZAMj... (The survey has just ONE short question: tell us who they are and what they could bring and contact info. We’ll work together to find the best fit.)

If you think your library or institution might be willing to become a supporting member of PsyArXiv, we would be very grateful if you can reach out to [email protected] [email protected], the PsyArXiv funding chair, will follow up and do the rest of the work :)

One of our members is conducting a study about instructors using government data. You can read more about her work on today's post: www.datarescueproject.org/teaching-wit...

PsyArXiv is seeking new moderators to help combat an increase in AI submissions! If you've ever posted a preprint to PsyArXiv, please consider joining. Minimum commitment 1h/month, there's a training session this Monday @ 1pm ET. More info here: forms.gle/9LB1rEtxHAeZ... #PsychSciSky

I often need to filter data in #rstats based on many variables. The dplyr::if_any() and dplyr::if_all() functions are really handy for this. More examples here: cghlewis.github.io/data-wrangli...

Help request. Qualtrics question: Need a script that would download surveys (.QSF/.DOCX) and their data (.CSV/.SAV) from a Qualtrics account. I have hundreds. I remember someone posting a script they did a while back. Know a solution? What's the easiest way to go about it?

Second, beyond career implications, doing open science & especially replications often comes with immense emotional burden & affects mental health. Ongoing harsh criticism, suspicion, & hostility, from senior scholars with immense power in the field, isn't something people normally want or look for.

This is good advice: "Whenever possible, avoid learning in isolation. And once you have given yourself permission to seek help, the next step is to choose carefully where that help will come from." It's also why I post and blog about statistics. Those are part of how I learn along with others.

New episode! @paulbloomatyale.bsky.social interviews Yoel about when to give up on a theory, and which of his own findings he no longer believes. But it's not all doom and gloom! We also talk about findings we think are solid, and, of course, Sydney Sweeney. share.fireside.fm/episode/Ah1O...

APS's journal AMPPS has accepted its first manuscript through a collaboration with a nonprofit that offers decentralized, community-driven peer review. @dsbarra.bsky.social 

I'm putting together some datasets relevant to the UN Sustainable Development Goals (for teaching purposes) and wondered if anyone has suggestions for interesting datasets on these themes. You can see what I'm aiming at in the first chapter. psyteachr.github.io/sdg-data/

In our next episode of Nullius In Verba we will dive into the history of metascience. The first mention of 'metascience' in the literature we could find is Morris, 1938. Do you know of an earlier mention of the term 'metascience'?

#RStats #Mplus help There is one model that is just not running (have had code checked by another person, no apparent issues), noticed that each time I try it results in a fort.16 file. Not finding guidance on forums about this + problem replicating btwn comps- any thoughts on if it's related?

My new PLOS Bio piece about when one's work is misrepresented: "[T]here is a normative expectation within scholarly research that all parties are well-intentioned and truth-seeking...when invitations to engage genuinely are not accepted..scholarly discourse is ill-equipped to resolve the conflict."

“This paper unpacks the concept of citation politics and its role in sustaining epistemic hierarchies within scholarly communities.” osf.io/qjecy_v2

Data Management in Large-Scale Education Research talk with @cos.io cghlewis.com/talk/cos/

Psychologists & related fields: what is a big methods question that you believe remains somewhat unanswered & that you'd love to see adressed? There may be an opportunity for a large-scale meta-science project with many teams trying to figure out a question. Any thoughts welcome! #psychscisky

We’re beyond honored to receive the SIPS Mission Award 🏆 & thrilled to have received 5 SIPS Commendations 🏆 for projects across our 4 core pillars: Metascience, Social Justice & DEIA, Community, and Education in OS. We are so grateful to all contributors who made this possible 💜 [All links below]

here’s a positive suggestion for academic publishing. Journals need to be accredited as meeting integrity standards in order to qualify for APCs enviromicro-journals.onlinelibrary.wiley.com/doi/full/10....

Reflecting on a comment I got as a student that using ratio scores as predictors is analogous to an inverse interaction term Wanted to sink my teeth into this a bit more after seeing a ratio score used but am surprised I'm not finding anything on Google Anyone aware of papers that dig into this?

A lot of discussions about open science in psychology happened on blogs. I have been archiving them and will make their content available. I remember 37 blogs (with 2827 posts!) but which blogs did I forget, and are not on my list? Please share and reply with any that are missing!

A consulting service where I read your applied methods book and just mark all the paragraphs that are so mathematically complex that if the reader had the stats background required to understand them, they wouldn’t need your book.

New blog post: Checking Data and Code in Repositories with Papercheck daniellakens.blogspot.com/2025/06/chec... We show how our Papercheck tool can automatically check and list files in data repositories linked to in a scientific manuscript.

💡Every open practice (data, code, prereg) is a spectrum! 🛠️ Begin with LOW-EFFORT practices. No "all or nothing"! Small steps build confidence, experience, & community 🤝. 🍔Detailed resources, guides, & tips are in the supplementary: osf.io/gu7v4 *(3/4)*

🔍 Key insight? Barriers are real (resources, access, incentives) – but actionable solutions exist! We propose a gradual engagement ladder 📈: Start small → build/lead communities. 💡 Remember: You can engage in community at any time! *(2/4)

🎉 After 2 years of work, our #OpenScience guide for researchers in developing countries is LIVE! Check out our new preprint: osf.io/preprints/ps... We map the opportunities 🌟 + barriers 🧱 facing Global South researchers. *(1/4)*
