Importantly, we also show that decoding accuracy holds whether or not you think the trait describes that person (ie trait endorsement). This suggests that when thinking of others, parts of your brain may be generating a general representation of them that is less sensitive to contextual information.

We don’t just lock on to our first impression of someone and call it a day. Instead, we regularly revise our appraisals as we learn more about them. But *how* do our brains make this process possible? Check out this fresh pre-print to see how we went about answering this question!
Excited to share this new preprint from @lindseytepfer.bsky.social, @chujunlin.bsky.social, and me, in which we investigate the different ways our brains allow us to change our minds about people! "The neurocomputational mechanisms of naturalistic trait impression updating" osf.io/preprints/ps...

A refreshingly sober view on important issues in mental health science that I think about a lot... I'm not as pessimistic/nihilistic as I come across sometimes, but I do worry deeply that we are often not meeting the challenges where they are.
Putting the two together: The mushy imprecision of our methods leaves room for almost any theory to be substantiated and for any 'mechanism' to find some kind of operational instantiation, but not really. Not at all, in fact, from where I stand. It's all so impossibly noisy and imprecise.
Ed Yong used to do amazing science journalism at The Atlantic... Now we get this: www.theatlantic.com/magazine/202...
Three psychologists use QRPs on dubious projects, grossly underpay participants, make coercive and sexist remarks, have their grants revoked, lose their lab space, and wrestle with the possibility of having to work in the private sector... And that's all in just the first 15 minutes of Ghostbusters.

Now in press at Cortex! "False discovery rate correction promotes confounded neuroimaging designs" Paper 🔓: www.sciencedirect.com/science/arti...
After 5 years, I finally carved out time to turn this blog post on FDR (markallenthornton.com/blog/fdr-pro...) into a manuscript. The preprint features a much broader range of simulations showing how FDR promotes confounds, and how this effect compounds with publication bias: osf.io/preprints/ps...

I am a neurodivergent neuroscientist. My bipolar brain brings struggle but it also helps me think off-the-map ideas. To help others who are similarly different, I co-founded the Neurodiversity Innovation Center for Excellence in Neuroscience (niceinneuro.org) with Leah Blankenship and Lila Kaye.

SCOOP: So remember Dialog, Peter Thiel's private society that doesn't have a public website and no public list of members? I (along with a number of other journalists) have just been tipped off that embedded in the code of their closed off website there IS what seems to be a list of some members.

Person identity drives neural similarity more than action and valence during dynamic emotion perception https://www.biorxiv.org/content/10.64898/2026.06.01.728854v1
Big congratulations to undergrad RA superstar Debbie Okeke for successfully defending her honors thesis "Investigating Neural Patterns In Dynamic Facial Processing Using Representational Similarity Analysis." Debbie started as a freshman in my lab and we are so proud of all that she has accomplished
I agree, but It's sad to me that people think we we do is "looking for __ in the brain." And the problem goes both ways. If you are interested in understanding brain, basing it on conceptually vague, poorly measured, or otherwise flawed ideas from psychology isn't helping make progress either.
This...the fetishizing of unreplicable neuroscience in order to legitimize our work is self-defeating. We don't need to know that depression is in the brain (as opposed to what???) to know it is problematic. How much money have we wasted proving something like depression is "real"?

Fortunate to be a part of this! Moriah had an incredible dissertation and I was lucky to be on her dissertation committee.
Excited to share our latest paper on computational mechanisms of self-enhancement with links to mental health. We used hierarchical Bayesian drift diffusion modeling to decompose choices on a social comparison task and relate them internalizing symptoms. journals.sagepub.com/eprint/GPFSV...
Also, after 19 years into my career, this is my very first empirical publication that is purely behavioral and has zero neuroscience... I'm officially a real psychologist!

At a different point in my life, this would have been shocking and disappointing. The only shocking part now is how numb I feel to this kind of news, and the disappointment is with myself for feeling that way. www.nytimes.com/2026/03/18/u...

A nice, level-headed post about the motivations and outcomes of using technology (including LLMs) in research that you care about.
New post! "Valuing the Process vs. the Product in Research," in which I try to describe some of the tensions around using GenAI/LLMs in scientific research, and why it can be so difficult to have productive conversations on the topic. getsyeducated.substack.com/p/valuing-th...
This also dovetails with thoughts I have had the topic too. People are using AI tools for lots of things in academia, and that's often perfectly fine. But I think it is important to be mindful about both what you are getting and what you are giving up. robchavez.substack.com/p/a-vibe-cod...

Five classes I took in college: - Styles of Scientific Argument - Analysis of Variance - Probability & Statistics for Engineers - Intelligence & Creativity - Advanced Data Analysis II That statistics minor is really pulling its weight... but man, most of my classes sounded so generic.
Oliver Sacks has always been one of my favorite writers, & I've tried to emulate him for a long time. However, anyone who has spent any real effort trying to translate their real-world experience into a compelling narrative knows how unstructured, anticlimactic, and uninteresting reality really is.
Incredible piece on Oliver Sacks. If you were ever awed at his supposedly true stories (I remember being stunned by the account of the autistic twins who rattled off large prime numbers), read this. He told wonderful stories, but they were in large part fiction. www.newyorker.com/magazine/202...
