Really enjoyed & honoured to be part of the Critical AI Literacy Symposium yesterday. Also @lucyavraamidou.bsky.social & @miquelpt.bsky.social (and others) spoke about their wonderful work too. Big thanks to @irisvanrooij.bsky.social, Leo & Barbara for organising. ✨

Please help us, #MetaScience community!

It's time to decide on a forever name for papercheck (scienceverse.github.io/papercheck/). We don't want it to be confused with papercheck.ai, and we plan to check other research artifacts like repo contents, data, code, and prereg. Any suggestions?
Check Scientific Papers for Best Practices
A modular, extendable system for automatically checking scientific papers for best practices using text search, R code, and/or (optional) LLM queries.

The computer scientist Daniel Spielman likens research to gambling. “It’s a big endorphin rush when you think you’ve solved something. And even if the usual outcome is that you’re wrong, that feeling of excitement is motivating.” www.quantamagazine.org/the-computer... #science #philsky

Research by Lee et al suggests LLMs exhibit human-like cognitive-behavioural biases characteristic of gambling addiction😬—like illusion of control, gambler's fallacy, and loss chasing; increasing models’ autonomy amplified risk-taking and bankruptcies:

A thought-provoking piece in Nature Neuroscience by many neuroscience colleagues: "Science must break its silence to rebuild public trust". Lots to think about here.

www.nature.com/articles/s41...
Public engagement: building common ground
How can we help to bridge this divide? Simply producing more excep­ tional science will not be enough to rebuild public trust. Rather, we must adopt a new model that recognizes communication and advocacy as core pillars of science, on a par with rigor and reproducibility. Public engagement efforts should be valued for faculty promotions, much like obtaining grants and publishing our findings in scientific journals. Researchers should be recognized and rewarded for activities such as giving public talks, working with local schools, engaging with policy­ makers, developing social media campaigns and platforms or writing accessible articles for general audiences. Developing these skills must be an integral part of scientific training, reinforcing the notion that the responsibility to champion science lies with us. Courses that teach graduate students and postdocs to communicate complex ideas clearly, to use social media effectively and to advocate for evidence­based policies must be deemed critical and supported by our universities. These efforts should not be viewed as distractions from research but woven into the fabric of what we do as scientists. Rebuilding public trust requires a cultural paradigm shift: scientists must see themselves not just as producers of knowledge, but also as its ambassadors and translators. Such a fundamental change will occur only if it is embraced by our scientific leaders and institutions, emphasizing the critical role of public engagement for science to succeed.

🌍 Carbon offsets largely fail to cut emissions

A 25-year review found most carbon offset schemes do not reduce global heating, with systemic flaws like double counting and temporary projects undermining real progress.

Carbon offsets fail to cut global heating due to ‘intractable’ systemic problems, study says
Analysis of 25 years of evidence shows most schemes are poor quality and fail to lower emissions

In 2018, Charles Murray challenged me to a bet: "We will understand IQ genetically—I think most of the picture will have been filled in by 2025—there will still be blanks—but we’ll know basically what’s going on." It's now 2025, and I claim a win. I write about it in The Atlantic.
Your Genes Are Simply Not Enough to Explain How Smart You Are
Seven years ago, I took a bet with Charles Murray about whether we’d basically understand the genetics of intelligence by now.

It can be hard to spot manipulative nudges on commercial websites, causing you to pay for something you didn’t want, locking you into a subscription etc.

On Wed Dec 10 join me to learn about what a regression model is, and what a regression model is not, while raising funds for World Central Kitchen and United Farm Workers. For details on how to register, sponsored registration possibilities, and more see betanalpha.github.io/courses/.
A slide with the text “Predicting a missing variate for a fully observed covariate, however, is not always the relevant predictive task.”, a probabilistic graphical model for predicting a missing variate given a partially observed covariate, and a corresponding equation for the posterior prediction distribution.

Make an effect size prediction!

@jamiecummins.bsky.social and I are replicating Balcetis & Dunning's (2010) "chocolate is more desirable than poop" (Cohen's d = 4.52)

Let us known in the replies what effect size you think we'll find. Details of the study in the thread below.
