I started making this R package 6 years ago. I finally have it in a state I'm happy with, thanks to Claude Code #Rstats github.com/MattCowgill/...

The Decision Process Scale (DPS): Self-report measures of reliance on rules, cost–benefit reasoning, intuition, and deliberation in (moral) decision-making - Behavior Research Methods Understanding how people make decisions in specific situations is a central challenge in (moral) psychology research. Yet there are no existing self-report scales for measuring the process of decision...

Now out in Behavior Research Methods! With @maxmaier.bsky.social & Falk Lieder, we developed the 12-item Decision Process Scale, which measures how much people rely on rules vs. cost-benefit reasoning and intuition vs. deliberation in individual dilemmas.

Dear colleagues - we want to better understand perceptions of data fraud and its detection and need your support! Are you currently a #researcher in #psych (or related fields) working with #data? Perfect - please respond to & share this short study (7min): sosci.rlp.net/detection/?r... Thank you!! 🫶

Also, been using this to find people to follow for a while:

Just realised that it's also from @theo.io, nice work, and thanks!

Nice bluesky tool!

Next Wednesday (Feb 11th) Dr @thecomplexbrain.bsky.social will join to guide us on how to uncover cognitive processes from open-text box data (full details: surl.li/mqtofs). All welcome (in person)!

dplyr 1.2.0 is out now and we are SO excited!

- `filter_out()` for dropping rows

- `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools

These are huge quality of life wins for #rstats!

Don't you f**king dare.

Researchers often present participants with stimuli that are assumed to reliably and exclusively evoke one, and only one, emotion category. This study shows that this is rarely the case for some widely used stimuli.

I built a basic shiny app to check doi's (with help of LLM, Claude Opus). The use case is for when students submit work with fabricated references (I used to randomly check, this will systematically check). Note it comes with no warranties,... . tvpollet.github.io/2026-01-30-D...

This is how you can split a plot into multiple subplots using #tidyplots 🚀

Join us for the LOVE REPLICATIONS WEEK from March 2 - 6 with talks on reproductions, replications, how to find them, how to conduct them, how to have them conducted on your study, where to publish them, and much more!

Really nice paper by @neillewisjr.bsky.social doi.org/10.1037/amp0...

Why Risk it, When You Can {rix} it: A Tutorial for Computational Reproducibility Focused on Simulation Studies

May be of interest to the reproducibility folks: New tutorial on computational reproducibility for simulation studies just dropped! felipelfv.github.io/Why-risk-it-...

by @felipefv.bsky.social, Jason Geller & @brodriguesco.bsky.social

Highly recommend Replication Games!

Key takeaways:
1. Great way to learn about other psych methods
2. Improve on stats
3. More enjoyable with others
4. Realised my own code needs improving after being on the other side of a paper (replicating)

Thanks @fialalenka.bsky.social @rujoanna.bsky.social

The Iowa Gambling Task is an extreme example of Jingle Fallacy and schmeasurement.

In 100 articles we found 244 different ways of scoring it, 177 were never reused. Correlations between them range -.99 to .99.

At the same time, we show meta-analyses combine these results as if they’re equivalent.

RegCheck RegCheck is an AI tool to compare preregistrations with papers instantly.

Comparing registrations to published papers is essential to research integrity - and almost no one does it routinely because it's slow, messy, and time-demanding.

RegCheck was built to help make this process easier.

Today, we launch RegCheck V2.

This paper in Management Science has been cited more than 6,000 times. Wall Street execs, top govt officials, and even a former U.S. Vice President have all referenced it. It’s fatally flawed, and the scholarly community refuses to do anything about it.

Most popular decision-making models assume that cognitive processes are static over time. In our new paper in Psych Review, we offer a simple extension to evidence accumulation models that lets researchers account for systematic changes in parameters across time 📈

To encourage reuse of our data, Pew Research Center, with support from the John Templeton Foundation, invites researchers to submit proposals for new research publications that use one or more of the following datasets (collectively, Datasets) from the Global Religious Futures (GRF) project: Global Restrictions on Religion 2007-2022 dataset. This cumulative dataset includes measures of government restrictions on religion and social hostilities involving religion in nearly 200 countries and territories. Spring 2024 Survey. This dataset includes measures of religion and spirituality in 35 countries. (Comparable data was also collected in 2023 and 2024 for the United States. The downloadable materials which accompany the international dataset include additional information about U.S. data.) Dataset of Global Religious Composition Estimates for 2010 and 2020. This dataset includes estimates of the size of seven major religious groups in more than 200 countries and territories. We encourag

Please share: Pew Research Center will provide $3,000 each for 19 new papers using our recent global datasets. We encourage reuse of our Pew-Templeton Global Religious Futures data!
