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!

dplyr 1.2.0
dplyr 1.2.0 fills in some important gaps in dplyr's API: we've added a new complement to `filter()` focused on dropping rows, and we've expanded the `case_when()` family with three new recoding and re...

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 🚀

#rstats #dataviz #phd
library(tidyplots) gene_expression |> head(n = 180) |> tidyplot(x = group, y = expression, color = group) |> add_mean_bar(alpha = 0.3) |> add_sem_errorbar() |> add_data_points_beeswarm(white_border = TRUE) |> adjust_size(width = 25, height = 25) |> split_plot(by = external_gene_name, ncol = 3, nrow = 3)

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)

On Jan 19th, we held the first Replication Games of 2026 at the University of Zurich! We had 47 participants reproducing papers from economics, political science, and psychology with great success. Many thanks to local organizers Johannes Ullrich and Joanna Rutkowska!

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.

How many versions of the Iowa Gambling Task (IGT) exist? And how much does this affect research using the IGT? More than you might think. 🧵

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 📈

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!
https://www.pewresearch.org/2026/01/16/seeking-research-using-recent-pew-templeton-global-religious-futures-datasets/
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.
