If you’re wondering why your friends in academia are a little on edge right now, it’s because an eighteen-year-old who hasn’t done the reading, doesn’t look at the assignment, and has does no critical thinking skills more complex than “because I think it’s in the Bible” can literally end your career
The University of Oklahoma has removed an instructor who was accused by a student of religious discrimination over a failing grade on a psychology paper in which she cited the Bible and argued that promoting a “belief in multiple genders” was “demonic.” https://cnn.it/4b6g3rd

1/4 New preprint! We designed an open-source system for auditory brainstem response (ABR), a research & clinical auditory test. Costs $400 to build (vs $10K to buy a proprietary one) and works great! All open-source if you want to make one for your lab or classroom. www.biorxiv.org/content/10.6...

Hey, @collabrapsychology.bsky.social , I love what you're doing overall! But... rejecting review requests is too hard! Declining requires logging in (why?!), and nobody seems to monitor email replies to your requests. Instead, I keep getting automated reminders for a paper outside of my expertise.

If you’re asked to review please feel free to postpone until January. (It’s what I’m doing, and journals usually happily accept. If not, less work for us 🤷)

Would you eat insects, or is that disgusting? @jonaspotthoff.bsky.social used mobile eye-tracking as people browsed a buffet. They looked longer at insect and unfamiliar snacks, but only rated insects as disgusting. This suggests disgust isn't always avoided when foraging decisions have to be made!

This paper is now out in Artificial Intelligence Review
Bottom line: using LLMs to "simulate humans" sits in a no-man’s-land between theory and empirics—too opaque to function as a model, too ungrounded to count as evidence.
Validation remains the core challenge.

The perceived embodiment of proper disgust is entirely different than that of “political disgust”, which actually closely overlaps with anger. Excellently timed preprint, with @disgust-nerds.bsky.social starting tomorrow. Hope someone brings this up in the “Is moral disgust really disgust?” debate!
