Prosocial behavior among familiars in the context of "spontaneous requests for immediate, low-cost assistance (e.g., to pass a utensil)" reveals that "cultural variation is limited, pointing to a common foundation for everyday cooperation around the world." www.nature.com/articles/s41...

Climate change terminology does not influence willingness to take climate action
Our new paper (N=6,132, across 63 countries) suggests that focusing on subtle terminology in climate messaging is not an effective use of resources.

Why are blue-collar voters drifting from the Democratic Party? Is it due to shifts in voter preferences or shifts in party positions? What role do cultural versus economic policies play? My Job Market Paper presents an empirical model that unpacks these dynamics.

Plot of engagement versus time for the same post on Bluesky and Twitter shows significantly higher engagement on Bluesky.
as an experiment, I posted the same post to twitter and bluesky.
here is the time series of engagements (sum of comments, reposts, likes) from the two platforms.
Note that I have 39K followers on twitter and 7K here, so engagement per follower here is more than 10 times higher here on bluesky.
This paper is a year old but I like it so much that I’m reposting :)

“Disclaimers such as “we are simply describing cross-sectional associations” are common, but they do little to prevent causal interpretations when the motivating research question is causal.”
I’d also add that… (cont’d)

Does social media use impact mental health? A principled re-analysis of Rausch and Haidt’s re-analysis. Short answer: no evidence that reductions in social media time improve adolescent mental health.
A favorite paper, with great coauthors. Birthweight inequalities were surprisingly similar in FR, UK, US, but mechanisms were very different. Income was important in the US but not at all in FR. In FR: mostly due to smoking, which was not important for US. And the UK? Somewhere in the middle!
This is the best Dennett obituary so far, not least because it mentions this perfect passage from 'Consciousness Explained'

I take you through what it's like to explore data through data visualization, focusing on causes of death.
How do you decide which chart is best? What do different visualizations tell you about the data? And why does dataviz matter at all?

Preregistering a one-sided test when you test a directional prediction increases statistical power with on average ~11% at no cost whatsoever compared to doing a (logically incoherent) two-sided test. You are welcome.
