A lot of psych is already conducted with online convenience samples & ppl are probably excited about silicon samples bc it would allow them to crank out more studies for even less 💸 How about we reconsider the idea that sciencey science involves collecting own data. www.science.org/content/arti...

Hi all! I'm on sabbatical this year and have bandwidth to zoom into lab meetings to talk about open science in cog psych and speech research and/or how to implement practices that reduce research errors! (www.carleton.edu/perception-l...). Email me if that sounds fun to you too!

I've been an AE at AMPPS for almost 5 years so happy to answer any questions - It's a fantastic opportunity to help shape methodological innovation and dissemination (and get the first glimpse of exciting new work!)

Life satisfaction mostly declines with age. Previous findings (esp. the famous U-shaped age-SWB trajectory) were artifacts of misspecified models. doi.org/10.1093/esr/...

Excited to share that I’ll be the incoming Editor of AMPPS. My first priority is building a diverse team of Associate Editors and Editorial Board members. If you’re interested, DM me or add your name via this super simple survey. cornell.ca1.qualtrics.com/jfe/form/SV_... Please share!

I am getting a lot out of this exchange about p-curve -- both on the substance of the debate, and on different approaches to thinking about it. Thanks to Uri and Richard for such an interesting back-and-forth.

Simonsohn has now posted a blog response to our recent paper about the poor statistical properties of the P curve. @clintin.bsky.social and I are finishing up a less-technical paper that will serve as a response. But I wanted to address a meta-issue *around* this that may clarify some things. 1/x

I am preoccupied with a workshop this week, gave a plenary this morning on scientific workflow. I am going to write this up as a paper - but for now here are some slides. Nobody break anything while I am offline please

A video of a class I gave at ELTE Budapest now online: "Credible science, evaluating science, & need for a science reform" Amazing they have an open-science "Defense Against the Dark Arts" course, and that they invited me to give a session. www.youtube.com/watch?v=y4Af... Details 👇🧵

Two new preprints on multilevel HMMs! Time series data is now pervasive in psychology and new methods are needed to model the dynamics in such data. Hidden Markov Models (HHMs) are powerful models for dynamics in which a system is switching between a number of discrete states.

`tinyplot` 0.5.0 is now available from CRAN & R-universe. Alongside bug fixes & internal improvements, this release includes some cool new features like bubble chart + dual legend support, element dodging, & ephemeral themes. Detailed changelog: grantmcdermott.com/tinyplot/NEW... #rstats #dataviz

Tidy simulation: Designing robust, reproducible, and scalable Monte Carlo simulations #StatsSky arxiv.org/abs/2509.11741 It is not formally linked to the {tidyverse}, bit affinity is obvious. The paper does a solid job in describing the simulation workflow, could be useful for intros to simulation

Noah's matching chops are completely out of control. What a chad.

Public appreciation post for @juliabottesini.com! The community doesn't know the great lengths Julia has gone to restabilize operations at PsyArXiv. We're all incredibly lucky to have her. Many, many hours and a great deal of thought/care have gone into the task. Thank you, Julia!

Looking forward to teaching a workshop at VU FEBA in Vilnius on “Sensitivity Analysis for Causal Regression & Mediation Designs” 🧑‍💻 📅 Oct 9–10 📍 TechHub 35-30 We’ll dive into robustness checks for causal inference + do some hands-on work in R & Stata. Excited for two days of learning + discussion!

A new paper I worked on is out in Justice Quarterly! I won't speak on the substantive nature of the paper as I worked solely as the methodologist, but I developed a new matching method not otherwise described in the literature, and I want to tell you about it! #statssky #casualsky

I got sucked into a great conversation and missed a talk I was excited for.... but luckily, @clauswilke.com puts all his work online in the most clean, organized, and helpful ways!!! 🥰 I've been using Claus's course sites as my templates for years, he is the best. 💙 clauswilke.com/PositConf2025/

Our preprint on our translations of CRediT into 36 languages. We've come a long way with this project! osf.io/preprints/me... If you know of non-English academic journals that don't have a policy on saying who did what, get in touch - CRediT may be part of the answer.

How is that not sci-fi

Do you want to get serious about specifying your random-effect structures? This paper might be for you.. plus lots of good stuff about multilevel and dyadic modeling: doi.org/10.1177/2515...

New blog post! Ever wonder what geom_histogram is actually doing? How about geom_boxplot? In celebration of the release of #ggplot2 4.0.0 (ggplot8?), I explore the relationships between the “geoms” and “stats” offered by the core {ggplot2} functions. #rstats

It has been loads of fun and is super popular (full auditoriums). It also happens to be very little work to organize. If you'd like to offer Guess Lectures at your institution, I wrote up a set of instructions to make it easier for you. Reach out with questions! docs.google.com/document/d/1...

LAUNCH DAY 🚀 Today I’m launching a new podcast, Hard Drugs, with Jacob Trefethen (@jacobtref.bsky.social) Our first episode is about lenacapavir — a new HIV drug that blocks infections with an efficacy rate of nearly 100%, and which could completely change the fight against HIV worldwide.

The new {marginaleffects} release for #RStats (0.30.0) comes with two new vignettes: 1. Speed up computation with automatic differentiation (often 10x gains) marginaleffects.com/bonus/perfor... 2. Power analyses with {marginaleffects} and {DeclareDesign}. marginaleffects.com/bonus/power....

I haven't used {DeclareDesign} before, but I have been using {marginaleffects} in my simulation-based power analyses for the past year or so, and I recommend you do too.
