Brilliant research requires a rested mind. Taking breaks isn't procrastination - it's part of the process.

Hi James - Do the puzzles have Sudokupad links in the book, or is just for pencil solving? Thanks!

As the attached illustrates, even when both paired samples come from the same distribution, BF₀₁ doesn't reach 10 with N=100. Am I thinking about it incorrectly?

Jim Grange @jimgrange.bsky.social · 19/08/2026
Can I ask a possibly silly Bayesian design question? If using a t-test Bayes factor as a sequential stopping rule, is it defensible to use asymmetric thresholds (say, BF₁₀ > 10 but BF₀₁ > 5)? This would require strong evidence for a novel effect but moderate evidence to stop pursuing it.

This could be done by (1) embedding open outputs in promotion criteria, valuing rigour & transparency over "high-impact" publications; (2) recognising data sets, pre-prints, and replication reports as valuable; (3) highlighting exemplars of researchers publishing negative results

Jim Grange @jimgrange.bsky.social · 14/10/2025
It's also interesting the piece calls for "a couple of high-profile funders or institutions" to provide momentum for a tipping point in promoting the publishing of negative results. This seems something an agile University could look to implement to lead the way.

Write for yourself, first & foremost. Use writing as a tool for thinking. I find t's not until I start writing that I realise my thoughts on a matter. Not just that, the process of writing helps sharpen my thoughts and signals where my thinking is not yet developed enough.

Jim Grange @jimgrange.bsky.social · 28/07/2025
The reason it's been on my mind is I feel a similar way: I used to write a lot a few years ago and feel strong hesitation in starting again. But a feel a piece of me is missing by not doing it. Maybe that's how you feel; maybe it's not. But I think—whether you publish it or not—you should write.

Jim Grange @jimgrange.bsky.social · 28/07/2025
