Ethics of ChatGPT and AI YouTube video by gwenvarley

Do you find it difficult to understand why LLMs — like ChatGPT and the like — are a form of ‘automated plagiarism’?

Take 3 min and listen to this excellent explanation by @gwenvarley.bsky.social

Excited to share our newest publication. Here we test a central hypothesis in cannabis use, does use alter a person's emotions in a theoretically expected way, and if so for whom and under what conditions is that observable. We found that cannabis use was linked to complex changes in emotions.

We're excited about SAS 2026! Mark your calendars to check out our lab's latest work.
Beginning with the Thursday preconferences, we have two lab members presenting at the Dev Precon and the Clinical Precon!

This is bait for a screenshot table response for my tenure packet

Looking forward to expanding our small team a bit as the lab prepares for its 2nd year.

We will be hiring 2-3 more volunteer, in-person RAs for our team to start in the fall. Details and application info are at our website.

Four more days left to apply for a Postdoctoral Research Fellowship in the Social Science Collaborartory.

For the right candidate, I'm upping the offer: I will double the supply of toy dinosaurs that come with this position 🦕

I'm sorry I usually try not to pile on but if you are going to (1) make a "challenge" post then (2) block responses and quotes but (3) allow people to repost you....

Graph of award probability of R35 and R01 from NIH factbook as a function of review rank percentile. As is apparent, 2025 is a significant departure, with lower award probabilities at all scores <40 and significant departures from norm, where even being in the top 10% is no longer a nearly certain indicator of success. Data source: https://report.nih.gov/nihdatabook/report/302

The data is in: the NIH goalposts have shifted.

What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards.

Another manifestation of how HHS policies have led to fewer awards and less science.

Thrilled that this first empirical paper out of the lab is posted, led by Sandarsh Pandey, asking:

Depression (and other internalizing disorders) involve profound changes to sense of self. How can we study these differences using rigorous decision-making methods?

Not just spontaneous remission: Time-dependent and independent effects in pre-intervention symptom reduction Psychological symptoms tend to change over time, even in the absence of clinical intervention. For example, self-ratings are often higher at screening…

🎉 I just published my second paper! Woo!
In psychotherapy trials we often see that symptoms reduce between screening and start of treatment. A plausible idea about that is that patients self-refer when their fluctuating symptoms are extra bad. We checked! (we tried to check) //

Attending @affectscience.bsky.social #SAS2026 and interested in interoception, emotion, and development? I'll give 2 presentations on March 12th on these topics!⬇️

To my health researcher colleagues: when you're looking at routinely collected data (over many years) and you're interested in the relationship b/w two kinds of events (say, diagnosis for diseases A and B), how do you best deal with time gaps (eg people moving)? Obviously these introduce time bias >

Data Visualization A Practical Introduction

@kjhealy.co has a new version of his data visualization book coming out and 1) you’d be a fool not to get it especially if you do R stuff 2) it’s gonna be even more beautiful than the first one, which is truly lovely book 3) he put the ENTIRE content on his website for free, you lucky so-and-so

Pooh meme: bored, I don't know anything about this... smug: this is beyond the scope of the paper

editing some writing atm...

Embarrassing, but also validating that embracing these practices will improve the value of the work my lab does while I am lucky enough to have one.

Very appreciative of Carmine for supporting this work, and Sara and Andrea for an amazing job during an intensive review process. @pnirs.bsky.social

A paper I led was also under review at BBI- one that had a coding error. I had forgotten to concatenate when calculating means, but since there was no error message I missed it. Thankfully this was caught in our open code/preprint by an interested reader + we added this anecdote to the review 5/6

To be clear, this review wasn't designed to point fingers at anyone- rather to see the level of engagement in a leading PNI journal + discuss opportunities and rationale for increased use of transparency practices.

Funny enough, the universe had some observational humor rolling my way 4/6

Almost half of papers were published open access (up from 2.9% in 2014), but the other transparency practices we reviewed were fairly uncommon.

Inspired by some of @tomhardwicke.bsky.social descriptive analyses on various open science practices, we evaluated the rate of open access publication, open code, open data, shared statistical output, and pre-registered hypotheses in empirical pubs from 2024 2/6

First PPDI Lab paper of the year, led by our amazing lab manager Sara Schwind (🚨she's on the PhD market next year🚨)! we reviewed the transparency practicesat BBI. #OpenScience 1/6

This story is nuts

The journal ‘Pediatrics and Child health’ has been published an article type, for case reports, that are made up and fictional without having any clear notice 😱

Have it saved to review on Friday. As much as I'm sure people will have lots of opinions I have been waiting to find a paper that comes with set expectations and guidelines to make these things a bit more concrete
