📘 With the release of our textbook "Bayesian Workflow" (avehtari.github.io/Bayesian-Wor...), I figured I'd also share the content of my graduate course on the topic at UBC. 🌎 charlesm93.github.io/stat547/ The course contains overlapping and complementary material, homeworks and reading.

someone reminded me, I had forgotten, that I put this crazy curve in as a practice problem in my book, page 236
7H1. In 2007, The Wall Street Journal published an editorial (“We’re Num-
ber One, Alas”) with a graph of corporate tax rates in 29 countries plot-
ted against tax revenue. A badly fit curve was drawn in (reconstructed
at right), seemingly by hand, to make the argument that the relationship
between tax rate and tax revenue increases and then declines, such that
higher tax rates can actually produce less tax revenue. I want you to actu-
ally fit a curve to these data, found in data(Laffer). Consider models
that use tax rate to predict tax revenue. Compare, using WAIC or PSIS, a
straight-line model to any curved models you like. What do you conclude
about the relationship between tax rate and tax revenue?

How not to defend science. A Decalogue for science defenders
SVEN OVE HANSSON
ABSTRACT
The public defence of science has never been more important than now.
However, it is a difficult task with many pitfalls, and there are mechanisms that can make it counterproductive. This article offers advice for science defenders, summarized in ten commandments that warn against potentially ineffective or even backfiring practices in the defence of science: (1) Do not portray science as a unique type of knowledge. (2) Do not underestimate scientific uncertainty. (3) Do not describe science as infallible. (4) Do not deny the value-ladenness of science. (5) Do not associate with power. (6) Do not blame the victims of disinformation. (7) Do not aim at convincing the anti-scientific propagandists. (8) Do not contribute to the legitimization of pseudoscience. (9) Do not attack religion when it does not conflict with science. (10) Do not call yourself a "sceptic".

213. The twentieth-century Catholic author J.R.R. Tolkien, in the words of a protagonist in one of his novels, described our responsibility in this way: “It is not our part to master all the tides of the world, but to do what is in us for the succour of those years wherein we are set, uprooting the evil in the fields that we know, so that those who live after may have clean earth to till.”

An XKCD-style webcomic featuring two characters against a yellow background. On the right, a wild-haired character in a lab coat stands next to a large mechanical device resembling a laser or death ray with a control panel. On the left, a blue-shirted character questions them.
The dialogue boxes read:
•	Blue-shirted character: "Why did you build a death ray?"
•	Lab-coat character: "To take over the world."
•	Blue-shirted character: "No, I mean what mad hypothesis are you testing? Are you just making mad observations? You at least are going to leave some of the world as a mad control group, right?"
•	Lab-coat character: "Look, I'm just trying to take over the world. That's all."
The caption at the bottom reads: "Sad truth: Most 'mad scientists' are actually just mad engineers".

I am still working on my analysis but tomdonoghue.bsky.social mosameen.bsky.social compared fixed and knee mode for sleep data, their discussion of the paper is here bsky.app/profile/tomd...

Daniel Borek @danielborek.bsky.social · 23/05/2026
When the data has more visible knee-like characteristics, as in some intracranial data, the models start to diverge. The knee model clearly wins in BIC evaluation, but the fixed model can still have quite high goodness of fit. One additional issue is that the knee model can sometimes “eat up” alpha.
110
Daniel Borek @danielborek.bsky.social · 23/05/2026
This is true even though, in principle, the exponents from these two models (knee and fixed) are not directly comparable, something akin comparing apples to oranges.
100
Daniel Borek @danielborek.bsky.social · 23/05/2026
My observation is that when the data looks much closer to 1/f “by eye” — for example, resting-state EEG — the knee and fixed-mode fits on the same dataset are much closer to each other in terms of model evaluation, such as BIC, and in exponent correlations.

Daniel Borek @danielborek.bsky.social · 23/05/2026
If the results are robust, great. If not, then we may be dealing with a garden of forking paths. I don’t think we yet have a fully settled community practice around this.
010
Daniel Borek @danielborek.bsky.social · 23/05/2026
I don’t have clear-cut advice here, but my recommendation would be to do some kind of sensitivity analysis before publishing: check whether the results hold with different parameters and slightly different fitting ranges, and report that as well.

Daniel Borek @danielborek.bsky.social · 23/05/2026
What happens when your specparam model specification doesn’t match your actual neural signal? I built a small WASM Python app to explore on simulations how model misfit can skew PSD shape and parameter estimates. Try it online here: danielborek.me/code-spectra... #EEG #MEG #Python #shiny
Screenshot of an interactive SpecParam knee simulation dashboard. The app shows controls for simulated spectral parameters, an explanation of knee parametrisation, and a log-log PSD plot comparing the true spectrum, noisy spectrum, knee model fit, and fixed 1/f fit. The knee model follows the curved spectrum, while the fixed model fit deviates as a straight line.

A terrific illustration of the trickiness in this space; thank you for it. To paraphrase Joe LeDoux: When researchers call a gene "hedgehog", no one confuses the gene/protein and the animal. But call it a "fear" circuit, and all manner of chaos ensues ... +1 for belief and its neural correlates.

This #infographic by Stephanie Phung is always a favorite example during my workshops. ✅ What WORKS in this infographic? • Consistency: colors, fonts, font sizes and illustration style are the same throughout the entire visual. Everything in the visual belongs together. 1/7
Infographic titled "Ocean Pollution" from worldoceannetwork.org, presenting key statistics about marine pollution across three visual layers representing the ocean surface, water column, and seabed.

Surface level highlights four facts: poisonous algal species have increased threefold; 1 in 20 adults will become ill after a single exposure to contaminated water; cigarettes are the most collected item during beach clean-ups; and 15% of our annual food intake consists of microplastics.

Mid-water level shows three statistics illustrated with silhouettes of marine animals: 267 marine species are prone to ingesting plastic debris (illustrated with a sea turtle); 55% of the fish we eat have ingested plastic (illustrated with fish among plastic bags); and 100,000 marine creatures die per year from plastic entanglement (illustrated with a seal tangled in debris). Two additional facts are noted: 70% of litter sinks to the seabed, and the average lifespan of a plastic bag is just 12 minutes.

From an old slide deck on replication research. Rewatching this episode of the Big Bang Theory hit differently after my own experiences with conducting replication research ;)
Image of a scene from the Big Bang Theory. Leonard is showing his mother Beverley around his University. When she learns that his recent research is attempting to "replicate" the research of an Italian group, Beverley is not very impressed. Beverley asks, "So, no original research?". Leonard says "no". Beverley responds, saying "Well, what's the point in my seeing it? I could just read the paper the Italians wrote."
