A Chess Scandal Revisited – Why Nakamura is Right About Cherry-Picking

Recently I was attended to a paper by Maharaj, Polson, and Sokolov, in which they provided a statistical analysis of a chess cheating allegation. Their abstract: We provide a statistical analysis o…

I am happy to announce the publication of our new work on the impact of arbitrary analytical choices on type I and type II error rates. We simulated reaction time data in a conflict task and analyzed the notable CSE effect in a multiverse manner. Worrying results:

I often see papers using GPower for power analysis in repeated measures factorial ANOVA designs. I don’t know what it’s doing, but it’s definitely giving wrong answers: substantially underestimates required sample size. MorePower seems like a much better alternative github.com/LewisPeacock...

I've spent the past weeks publishing my flankr package on CRAN for R. Users who've only installed the first version will notice SIGNIFICANT improvements in model fit speed.

Plus, I made a hex sticker for it.

Well this is a delightfully clever study. Check it out.

On the left is a rabbit. On the right is an elephant. But guess what: They’re the *same image*, rotated 90°!

In @currentbiology.bsky.social, @chazfirestone.bsky.social & I show how these images—known as “visual anagrams”—can help solve a longstanding problem in cognitive science. bit.ly/45BVnCZ

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 · Jul 28

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 · Jul 28

Your post has been at the back of my mind for the past couple of days. I 100% think you should start writing again. I've certainly valued your writing.

I only started running properly around my 40th. I've just turned 44, and training now for my 5th marathon. A half mara is a gateway drug to the full mara, so see you on the start line of a full marathon soon :)

Reminds me of this paper from Andrew Bayliss (now UEA):

The amber indicator lights on cars are designed to enable road users to efficiently predict the driver's next manoeuvre. Among other factors (e.g. luminance), the spatial configuration of these light...

Can I ask what the format of the (half) day was? Always interested in how other departments approach research away days. (Currently planning our research week here for early Sept.)

Jim Grange @jimgrange.bsky.social · Jul 14

Unlike standard publishing you absolutely CAN send the same proposal to multiple publishers to try and get the best deal. We had 3 publishers on board for our book proposal and were therefore able to choose the one we preferred.

Not only is this a *superb* paper, I'm learning so much from the code posted online. Thank you @gidon-frischkorn.bsky.social!

I use this format in all my documents & spreadsheets much to the dismay of my colleagues. (I'm in the UK.)

A short (let’s see!) blog post about leadership, which has been on my mind lately. But first, a digression. Regular readers will have noticed I’ve not been posting much. This is because…

Hot take: Some computational modellers don't share readable, complete code—or offer help when asked—because gatekeeping methods gives them a professional edge. It's bad for science and worse for collaboration.

Jim Grange @jimgrange.bsky.social · Jun 16

I'm therefore committed to only sharing usable software and readable model code. And if there's something that's not clear to someone, I will do everything I can to help.
