I am devastated because our cat Trasno is critically ill and needs urgent treatment to survive, but it’s financially overwhelming. If we’ve ever made you smile or feel supported, please consider sharing or contributing: gofundme.com/f/help-save-...
Thank you from the heart,

Our experience at @pci-regreports.bsky.social was great - Really helpful and collaborative reviews and editors, made for a refreshing change from the usual grind of the academic review/publishing process!

If any folks are PCI-curious, would totally recommend! 😊

Caveat 2) We measured climate *concern*, not climate *anxiety*. It's possible that reactions to the climate crisis which are more extreme than mere 'concern' have an impact on mental health - We simply can't infer anything about this from our paper
djsmith90.bsky.social
Many caveats though (ofc!)

1) Just because we *tried* to estimate a causal effect, doesn't mean we *succeed*. Our causal estimand was our target, but our aim may have been terrible, but we at least tried to be open about these issues (unmeasured confounding, selection bias, measurement error, etc.)
djsmith90.bsky.social
What did we find? Pretty much nada!

In this UK population of young adults (~30 years old) there was essentially no relationship between climate concern and subsequent mental health/well-being
djsmith90.bsky.social
Using the wonderful longitudinal ALSPAC data, we tried to answer whether concern over climate change causes subsequent mental health.

Lots of previous work has looked at climate anxiety/concern and mental health, but most is X-sectional, so is almost impossible to learn anything about causality

The world may be a burning shit-storm, but we're trying to do our little bit to make science slightly better - Our new Registered Report on climate concern and mental health was just recommended/accepted at @pci-regreports.bsky.social

📣 New paper by myself @djsmith90.bsky.social and colleagues published today in @royalsociety.org Proc B 📣

Grandmothers are often seen as key carers, but this isn’t always the case.

We explore why in Agta forgers reflecting on the implications of demography for evolution of grandmothering 👵🌍

AnthroTools 2.0 is live! Nine new functions that propagate, plot, and summarize uncertainty around item and cultural salience values. @djsmith90.bsky.social @bgpurzycki.bsky.social @rcc-au.bsky.social

As a side note, even if you don't give a hoot about free-list data, check out the paper for the sweet use of LaTeX - Looks pretty legit, right? (What are we paying journals the big bucks for again...?)
djsmith90.bsky.social
We focus on salience scores, starting simple with bootstrapping methods, followed by more principled/bad-ass Bayesian ZOIB and ordered Beta models (they sound scary, but are super-cool).

This approach can be also applied to other free-list metrics as well (Jaccard's similarity, cultural FST, etc).
djsmith90.bsky.social
Are you into free-list methods and want to incorporate uncertainty into your group-level estimates (eg Smith's S)?

Of course you do!

Then @bgpurzycki.bsky.social and I have a new preprint for your delectation!

No clear co-causal evidence of religion and mental health! Hot off the digital press from RCC's @djsmith90.bsky.social!

New blog post!

Sometimes, when reviewing a manuscript, it's really unclear to me what precisely the authors are trying to do -- which makes it hard to evaluate the work properly.

So, here's some advice for how to ensure that readers don't get lost.

Reviewer notes: Avoid any ambiguity about analysis aims
For any central statistical analysis that you report in your manuscript, it should be absolutely clear for readers why the analysis is being conducted in the first place – that is, the analysis goal s...

1/ 🧵 New preprint out today 🤩

With @djsmith90.bsky.social and co we have done deep-dive into grandmothering in the Agta to unpick the role of demography in shaping the role of grandmothers in direct childcare 👇🧪🏺

Did not expect my first inclusion in a starter pack to be "people named Dan Smith with PhDs"! 😅

Still, at least you now know where to find us!

Everybody should have a few Dan Smith, PhDs in their feed.

I found @djsmith90.bsky.social's figure about ethical publishing so helpful for students I added it to my guide to academic reading/writing/publishing (osf.io/p37zj)
Screenshot from article including meme and figure of more and less ethical academic publishing options
djsmith90.bsky.social
Yeah, I'd reckon probably somewhere around there, or a bit to the left with the 'society' journals - technically AAAS is non-profit, and it doesn't act as much like a commercial publisher than CUP and OUP.
djsmith90.bsky.social
Ace, thanks Pat!

And very cool (I mean, depressing as hell, but still very cool) - Thanks for sharing 😅
djsmith90.bsky.social
Alas, I agree with @drbeth.bsky.social that it's still super-common (eg, anecdotes about hiring decisions made on having a Nature/Science/Whatever paper)... Hopefully will start changing more soon though! 🤞

V. interested to know what you find if you do a deep-dive into this 🙂
djsmith90.bsky.social
A lot has been written about this recently, but I think it's still useful to remind ourselves just how warped and unfair the academic publishing system is

The blog goes through:
- How the system is unfair
- How it got that way
- What we can do to (try and) change it

Hope it's of some use! 🙂
