This is called “chain refoulment” and it’s illegal under both U.S. and international law. And the State Department and ICE know very well what Ghana is doing and simply don’t care.

A third infant in Kentucky has died of whooping cough this year.

Reminder: The best way to protect against whooping cough is to get vaccinated. Adults should get a Tdap booster every 10 years, so please check, you may be overdue!

Administrators gave themselves uncapped "performance" raises while the rest of us have a 4/4 load, no research or travel support, and no way to fill lines left empty by retirements.

Administrators got housing stipends while most of us can't afford to live near the institutions we work at.

You can think of decisions as evidence accumulation, and the accumulator as an RL policy. Then, dopamine in the basal ganglia works by dynamically changing policy to maximize reward rate 🤯 A tour de force modeling paper by @tdverstynen.bsky.social and team! journals.plos.org/ploscompbiol...

So we now have likely mammal-to-mammal transmission of the bird flu at the same time that our national health agencies leadership is actively attacking public health.

This is a bit terrifying.

Air Pollution From Industrial Facilities Is Far Worse Than Estimated The Trump administration has put a stop to EPA rules that would have required more than 130 industrial facilities to install air monitors to measure pollution. Millions of people living near these pla...

About 90,000 people living near larger chemical plants face an unacceptable risk of developing cancer, the EPA says.

New rules adopted last year could’ve cut that number to 3,000 residents — a drop of 97%.

But Trump has halted those efforts.

Our new paper is out in Nature Communications! nature.com/articles/s41...

We combined psychophysics, 7T fMRI, and computational modeling of vision with placebo, 5mg, and 10mg psilocybin, in the same group of participants, to clarify the computational mechanisms of psychedelics. 🧵

I remember talking to Michael Silver (UC Berkeley) a long time ago about how he found a similar effect in people with schizophrenia. Not sure if he published it or not, but it was really puzzling him at the time.

In other words, we found that psilocybin altered a fundamental computational building block of contextual processing in the human brain: divisive normalization, particularly in the form of visual surround suppression.

Enter the divisive normalization population receptive field model. The parameter governing surround suppression systematically dropped with psilocybin! This could not be explained by noise or HRF changes alone, which are also included in the model. 🤖

This paper provides guidance and tools for conducting open and reproducible systematic reviews in psychology. It emphasizes the importance of systematic reviews for evidence-based decision-making and the growing adoption of open science practices. Open science enhances transparency, reproducibility, and minimizes bias in systematic reviews by sharing data, materials, and code. It also fosters collaborations and enables involvement of non-academic stakeholders. The paper is designed for beginners, offering accessible guidance to navigate the many standards and resources that may not obviously align with specific areas of psychology. It covers systematic review conduct standards, pre-registration, registered reports, reporting standards, and open data, materials and code. The paper is concluded with a glimpse of recent innovations like Community Augmented Meta-Analysis and independent reproducibility checks.

There is no reason why systematic reviews can't be open. The data used for synthesis is *already* open and there are many excellent open source tools that can facilitate the easy sharing of analysis scripts.

Here's a nice guide for performing open systematic reviews doi.org/10.1525/coll...

A friend who teaches theology shared with me a post about CS Lewis's Mere Christianity, which discusses foundational Christian logic across denominations. It reminded me of Dale's tweet below, and I wanted to share some thoughts here regarding modesty and respectability, which are often hot topics.

I don't understand how anyone can watch how blatantly Grok is manipulated to answer the way ownership desires it to and then act like the other LLM chatbots couldn't possibly be similarly but less obviously compromised to produce responses in whatever way corporate interests and priorities dictate.
