"Dunbar's Number" is a zombie that lives forever in the science press it seems. Estimates of Dunbar's Number with 95% intervals, for a range of model specifications (from doi.org/10.1098/rsbl... ):

Against Publishing: universonline.nl/nieuws/2025/...

Preprints are read, shared, and cited, yet still dismissed as incomplete until blessed by a publisher. I argue that the true measure of scholarship lies in open exchange, not in the industry’s gatekeeping of what counts as published.

Replication science isn't always fun, but this one is. Help a guy out:

Ian Hussey @ianhussey.mmmdata.io · 2d

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.

If correlation was causation, many of us wouldn't have jobs

it does kinda suck that every pre-4.0.0 ggplot2 plot that set theme(base_size) will look different now

I'm in an earnest kinda mood. So it goes...

I find it hard to understand how finding the model that best captures your understanding of the data is somehow a bad use of your time.

Solomon Kurz @solomonkurz.bsky.social · 6d

Disagree. Even when you pay a hefty premium for insurance, it's best to never use it.

Also, my fondness for the self-deprecating humor aside, I don't like this take. Learning proper missing data techniques are never a waste of time.

The key part is that the value is negative, though -0.2 is a good starting point

Solomon Kurz @solomonkurz.bsky.social · 6d

Set `position = position_dodge(height = -0.2)` within the point-interval geom so that the vertical ordering in plot matches the vertical ordering in the key.

I’ve been invited to interesting Slack groups, I’ve received job offers, I’ve been invited to give presentations, and I’ve gotten a book deal.

@matthewbjane.bsky.social, thoughts on any of this?

Solomon Kurz @solomonkurz.bsky.social · 8d

I think we agree.

One *can* interpret sigma from y ~ group + some_covariate, but such a sigma is no longer the population pooled SD in the conventional sense, and is therefore not a great choice for a standardizer of a standardized mean difference (at least not in the typical sense).

In other words, sigma from y ~ group + some_covariate is no longer an estimator of the population pooled SD. It's just a statistical artifact at that point.
