Two-group pre/post data are deceptively simple, and you could analyze them in many different ways, depending on your goals. Here are three blog posts on the topic: solomonkurz.netlify.app/blog/2022-06... solomonkurz.netlify.app/blog/2020-12... solomonkurz.netlify.app/blog/2023-06...

Okay, here are some first reflections on Watson. Watson's life is a tragedy, really of Shakespearean proportions. He did not, as most bios will tell you, do one great thing when he was young and then collect laurels for it for the next 60 years. His career arc was unlike any in science.

My Shiny app containing 3530 Open Science blog posts discussing the replication crisis is updated - you can now use the SEARCH box. I fixed it as my new PhD Julia wanted to know who had called open scientists 'Methodological Terrorists' :) shiny.ieis.tue.nl/open_science...

The entire "editor writes headline" tradition is a stupid remnant of print journalism where it was necessary for physical layout purposes. It never has made much sense for online journalism, let alone online op-eds.

Overwhelming evidence of research fraud and he still earns 190k/year www.ontariosunshinelist.com/people/steve...

My reviewing style has changed over time. Rather than litigate every little thing, and pushing my own ideas, I focus only on 2 things: (1) Are the claims interesting/important? (2) Does the evidence support the claims? Most of my reviews these days are short and focused.

Youyou Tu's work on anti-malarial compounds that saved millions of lives (w/Nobel+Lasker recognition) wins the low citation/huge impact cell. The original paper has 87 citations as of today: pubmed.ncbi.nlm.nih.gov/11721477/ Hopefully she can get to 100. What for huge citations and moderate impact?

Haha, this from the New Yorker is getting passed around the math dork community. I did a comic about this kind of thought a few years ago: www.smbc-comics.com/comic/commut...

Exactly! Which makes the real climate shift way scarier. Like shown by the data from svs.gsfc.nasa.gov/5452/

I appreciated the debate yesterday about how to interpret the results of the cognitive dissonance replication study Scroll up to read the points made by researchers on both sides

Oops. Ooooooooooooops. I do hope that nobody has been given or denied a job/promotion based on their SpringerNature citation counts in the past 15 years. arxiv.org/pdf/2511.01675 h/t @nathlarigaldie.bsky.social

A recent redesign of OSF by @cos.io led to widespread access failures. What began as a few broken download links became for me a total disappearance of eight years of DOI-registered work. What happened, how was it resolved, and what it reveals about trust and infrastructure in open science

There’s growing evidence that something was going seriously wrong in the classic early work on cognitive dissonance Latest revelation: The story in When Prophecy Fails seems to have been fabricated in the most egregious way But this is not the only one… onlinelibrary.wiley.com/doi/abs/10.1...

I strongly recommend @hugoreasoning.bsky.social's book "Not Born Yesterday" if you've been exposed to too much social psychology about irrationality in your youth. press.princeton.edu/books/hardco...

This unexpectedly blew up when I was sleeping. Just a few precisions to (hopefully) be a bit clearer: 👇 bsky.app/profile/nath...

Ok, just wow. If the content of this article is right, this is depressing. We're slowly reaching the point where ~100% of what I was taught in Social Psych was either innocently wrong or plainly frauded onlinelibrary.wiley.com/doi/abs/10.1...

I’ve spent the last 8 years(!) working from the position that HiTOP relies too much on analyses of traditional diagnoses, baking in limitations of the DSM, and that we need to move to symptom-level analyses to fix it It turns out that rebuilding HiTOP from the ground up doesn’t change much 💀 1/

@lakens.bsky.social pointed out on twitter that these text-mining studies (on mostly abstracts) are biased to overestimate the problem because exact test-statistics are more often reported for significant tests while non-significant tests are just described in words.

So a recent Veritasium video on natural selection explains kin selection and does the unavoidable thing of saying that a parent shares "half of its genes with the child". This is wrong, because for any 2 humans, we share almost all of our genes. We share more than 95% with chimpanzees ffs. >>

The package formerly known as papercheck has changed its name to metacheck! We're checking more than just papers, with functions to assess OSF projects, github repos, and AsPredicted pre-registrations, with more being developed all the time. scienceverse.github.io/metacheck/

Richard Lynn was criticised for using a sample of children with intellectual impairment to calculate the "national IQ" of Equatorial Guinea in 2002. In 2019, he calculated the IQs of Native Americans from children referred for psychoeducational evaluations, including those with learning difficulties

There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >

Exciting new addition to the AsPredicted and ResearchBox research infrastructure toolbox: AsCollected ascollected.org A platform to document results provenance - where did data come from, who collected it, and who cleaned and analyzed it. So important!

Is social media dying? How much has Twitter changed as it became X? Which party now dominates the conversation? Using nationally representative ANES data from 2020 & 2024, I map how the U.S. social media landscape has transformed. Here are the key take-aways 🧵 arxiv.org/abs/2510.25417

If Schrödinger's classic 'What Is Life?' is important to you, grab this book (free for 1 more day?). It's short, and although it throws shade on the genetic program concept ('m still a fan), it provides lots of interesting context and a fair assessment of the impact of What is Life? 🧪

34. Europeans shouldn't feel guilty about using electricity for airconditioning, it'll all come from the sun anyway by 2030. Solar generation times and seasons match airconditioning demand pretty well, which is good news for really hot countries as well.

The most challenging part of writing is coming up with a good continuation for what I've already written. The underlying message was never the problem. That's literally what an LLM excels at. I don't get why people hate them so much.

I laughed about Huel being “spiritually bad.” I also wish one could just trust media outlets that break news about supposedly troubling contamination to not lean into the story at the cost of scientific accuracy.

When I was an undergrad, I saw a talk by Oliver Sacks about music. During the Q&A, someone asked Sacks if he thought science would reveal the deepest mysteries of art. Sacks (a rare humanist among scientists) said that he doubted it, at which Eric Kandel (the host) leaped up and grabbed the mic.

Academia is supposed to be an open environment where people can disagree with each other, but people are happy to keep your work invisible if they disagree with some minor thing. I suspect many rejected papers are perfectly fine and rejection is wasting everyone's time and mental health.

Next time an institution tells you how seriously it takes research misconduct, ask them if it's *this* seriously. www.bmj.com/content/297/...
