The #ABCT2025 panel on gambling led by @joshuagrubbsphd.bsky.social is giving me so many great ideas and also making me very worried for what is coming as sports gambling continues to grow.

Shoutout to the Fox Sports crew for showing some actual emotion when discussing the death of Marshawn Kneeland during this Minnesota Vikings game. Instead of just reading the card and moving on, they addressed the real impact of these losses and concrete steps people can take to support each other.

My week has been deeply affected by the death of Daniel. More than a chess streamer/commentator he was a lifeline during many dark times and I spent hundreds (thousands?) of hours 'with' him over the years. I will miss his humor, his passion, his joy. RIP Danya. www.chess.com/news/view/gr...

Given that people are using LLMs as therapists (even though they should not, of course), it has made me wonder if trained clinicians would use these tools differently than the general public? That is, would they ask different questions, better prompts, etc? Free research idea!

If I was still a college professor, I would assign my students this thread and have them each pick one topic to explore and then do a brief presentation on what the problem is and why it affects the field. Of course, then I would have to grade it...
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.

If you read my thread, make sure to read the retracted paper’s last author’s response. As I highlighted on pubpeer & my thread, authors have been very responsive, transparent & collegial all the way through. I was surprised myself seeing a retraction as I had asked for a correction.
Hi I’m the last author of the retracted study; the first author is my PhD student. I don’t disagree with the retraction note. However, it missed out on some important context that I had written in my author’s response, which was not published with the retraction note. Here’s my side of the story

Journal publishers have guts, I will give them that. I spent 5-6 hours formatting an article to meet the criteria for a particular journal, it sat on the editors desk for a month and was desk rejected. Now they want me to complete a survey about it, but fear not, it will only use 10 min of my time!

Let's say my wife gave me a research idea and she ends up as an author on the paper (I mean, counts as conceptualization, right?). However, she works in the private sector in a field unrelated to research. How would I handle the "affiliation" part of the article submission?

I've been spending some time working out the Stan code underlying simple brms models, and I think I'm going to write a few #rstats blogs walking out the topic.
Who'd be interested in peer reviewing the posts?
Basic fluency with brms and rstan would be required.
