@sjwithnell.bsky.social
Clinical Psych PhD at Western University, Canada. I study biopsychosocial weight factors related to #eatingdisorders.
THANK YOU for this paper! I've been losing my mind wondering why nobody is discussing how the black box of AI models might be a threat to years of open science efforts
New preprint 🌟 Psychology is core to cognitive science, and so it is vital we preserve it from harmful frames. @irisvanrooij.bsky.social & I use our psych and computer science expertise to analyse and craft:
Critical Artificial Intelligence Literacy for Psychologists. doi.org/10.31234/osf...

To be honest I think the global workforce in call-center-like scam factories has already made online surveys without ID verification untenable - if anything LLM's are just putting the people working in these factories out of job
new paper by Sean Westwood:
With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research

Would be great to see some more Canadian profs on this list for students looking for clinical psych programs! I think @kvonranson.bsky.social is the only one I spotted 👀

It's becoming clear that, if I want to finish my dissertation, I can no longer avoid learning how to run for/while loops in R. If anyone has any resources on this topic, please let me know! I briefly learned python loops in an undergrad programming class but am extremely rusty!

🚨New paper alert!
In my first first-author paper for my #PhD, we explored free-text responses from 1,600+ people with #eatingdisorders to better understand the diverse behaviours used to lose weight, many of which fall outside diagnostic criteria
Here's what we found👇

I'm so excited to attend #ICED2025 this week, I might finally install bluesky on my phone! On Thursday I'll be presenting a newly published paper looking at within-person assocs btw weight suppression, weight loss intentions and ED outcomes. Hope to see some folks there!

🚨 New study reveals that when used to summarize scientific research, generative AI is nearly five times less accurate than humans.
Many haven't realized, but Gen AI's accuracy problem is worse than initially thought.

You guys don’t need to try to convince me that any form of AI has merit. It doesn’t. It is boring and half-assed. I am fine getting by with human brain power. If the world nears its end and AI has one hater left, good news! I am still alive.
