Bayesian probability, like frequentist probability, is a model-based activity that is mathematically anchored by physical randomization at one end and calibration to a reference set at the other

OUR BLESSED mixed models vs THEIR BARABAROUS fixed effects OUR GLORIOUS Mundlak device vs THEIR WICKED demeaning OUR GREAT variance components vs THEIR PRIMITIVE dummy variables OUR NOBLE partial pooling vs THEIR BACKWARD unbiased estimates OUR HEROIC maximum likelihoos vs THEIR BRUTISH least squares

I could have sworn I created this before on our Previous Parish, but couldn't find it so made it fresh.

I present:

I've been working on a new tool, Refine, to make scholars more productive. If you're interested in being among the very first to try the beta, please read on.

Refine leverages the best current AI models to draw your attention to potential errors and clarity issues in research paper drafts.

Great news! congrats:)

Nice new paper in PNAS providing further evidence that random/long ties help social contagions — even many that would be labeled "complex contagions"

Postdoctoral Position | Center for Adaptive Rationality

We are hiring, @arc-mpib.bsky.social a postdoc for a project to investigate why citizens feel alienated from liberal democracy and how a shared sense of reality can be restored.

Cognitive representations of social networks in isolated villages - Nature Human Behaviour Feltham et al. develop a sampling strategy to evaluate social network cognition across 82 Honduran villages, systematically mapping the underlying village networks.

New by @ericfeltham.bsky.social, Laura Forastiere, and @nachristakis.bsky.social: an extraordinarily ambitious effort to scale up and bring Krackhardt's classic work on cognitive social structures (CSSs) into the 21st century. Super excited to see it in print. www.nature.com/articles/s41...

People not only form social networks, they construct mental maps of them. People think about the ties between other people, including ties among individuals to whom they are not themselves directly connected. These “cognitive social networks” have rarely been studied. 1/

in a sequential social learning scenario, a sequence of agents make binary decisions on the basis of their private signals and information available to them from past choices. information cascade in this scenario refers to discounting of new private information in favor of past public actions

@yuxin-pitt.bsky.social presenting shortly in responsiblecomputing.org/forc-2025/ (extended abstract: drops.dagstuhl.de/entities/vol... - working paper: arxiv.org/abs/2502.19525) also last month at the Network Science in Economics conference, both in beautiful Stanford bsky.app/profile/yuxi...

smooth randomized response guarantees learning at log(n) rate that is much faster than the sqrt(log n) rate in the non-private case & achieves finite expected times to the first correct action and last incorrect action, both of which are infinite in the non-private case + same eps can minimize both

a simple randomized response that flips actions with constant probability will prevents any cascade and asymptotic learning, but we can use a smooth version that hides signal locations within a range; this way, actions can be flipped with a probability that decays smoothly outside the range
