Check out our new paper, where we used 7T fMRI to map out a brain system central to sensing and regulating the body! Based on prior animal studies - which tracked white matter traveling to/from the body - we mapped this system from cerebral cortical networks down to subcortex and brainstem nuclei.

Excited to share our work making an "allostasis-first" case that brain function is most productively framed in terms of its core regulatory function. We also introduce some new ideas in the context of metabolism and cognitive function in Alzheimer's.

I would LOVE to do this!

What percentage of publicly funded studies have serious, but entirely avoidable, methodological flaws?

Sadly, I don't think any of the big funders would be courageous enough to support this.

We should do a study on how much of the funded applied research suffers from problems that the unfunded methods research could have helped prevent or resolve

Announcing such a major change to NSF GRFP this late in the cycle is incredibly cruel. 2nd yr students (mine included) have been working so hard on their proposals despite ongoing uncertainty. They are driven and passionate about being outstanding scientists and helping those coming up behind them.
This means individuals in the following statuses at the time of application are eligible: Undergraduate in the final (senior) year of a bachelor’s degree program Bachelor’s degree-holder with NO enrollment in a graduate degree program (non-degree graduate coursework allowed) Individual enrolled in a joint bachelor’s-master’s degree program with at least three undergraduate years completed First-year graduate student in their first graduate degree program with less than one academic year completed in the degree program (according to institution’s academic calendar) Individuals enrolled in joint bachelor’s-master’s degree programs are considered graduate students. For GRFP, joint bachelor’s-master’s degrees are defined as degrees concurrently pursued and awarded. Not be a current NSF employee. Applications that do not meet eligibility requirements will be returned without review as being ineligible for a fellowship.

Wherever a researcher comes down on natural kinds, constructs & Operationalization, I agree it would be great for more to realize it’s a thing to think through it all wrt “What are we doing here?” This book (especially the Intro start) is good to get the gist.

Really pleased with how this turned out, giving new insight into the linguistics of therapy: Found that LLMs estimate psychological distance better than dictionary-based methods used in prior work (www.pnas.org/doi/10.1073/...), also finding that therapists who *encourage* distance fare better

🚨 New paper alert 🚨 Using LLMs as data annotators, you can produce any scientific result you want. We call this **LLM Hacking**.

Paper: arxiv.org/pdf/2509.08825
We present our new preprint titled "Large Language Model Hacking: Quantifying the Hidden Risks of Using LLMs for Text Annotation". We quantify LLM hacking risk through systematic replication of 37 diverse computational social science annotation tasks. For these tasks, we use a combined set of 2,361 realistic hypotheses that researchers might test using these annotations. Then, we collect 13 million LLM annotations across plausible LLM configurations. These annotations feed into 1.4 million regressions testing the hypotheses. For a hypothesis with no true effect (ground truth $p > 0.05$), different LLM configurations yield conflicting conclusions. Checkmarks indicate correct statistical conclusions matching ground truth; crosses indicate LLM hacking -- incorrect conclusions due to annotation errors. Across all experiments, LLM hacking occurs in 31-50\% of cases even with highly capable models. Since minor configuration changes can flip scientific conclusions, from correct to incorrect, LLM hacking can be exploited to present anything as statistically significant.
