New paper w/ @verwirrt.bsky.social and @lottybrand.bsky.social. We use agent-based modeling w/ NK landscapes to help theorize about role of analogies in language/cultural evolution, and how they solve problems associated with the transmission of complex information. www.cambridge.org/core/journal...

Of all the professions AI might make obsolete, mathematician is the one I’m most relaxed about. But i’m biased, I know a lot of mathematicians.

"It is time to demand that our courts open the black boxes of algorithmic decision-making. We need to shift the burden of proof to the party that actually has access to the algorithm, and design procedural rules for effective systematic redress." #AIEthics #AIAct #AILaw #digitalGovernance #RuleOfLaw

This pair of episodes (Mandelson and New Labour as a five act history play) is so so so so good. I kinda want to write an essay about how we should fund academia properly just so these two people can meet and talk to each other

This week's Cooperation Colloquium: Aron Szekely @aronszekely.bsky.social Measuring social norms with surveys Date: Friday, April 24 Time: 15:00 UTC+2 (Vienna) / 9am ET (NYC) Sign up: list.ku.dk/postorius/li...
Abstract: Accurately measuring social norms is crucial both for explaining cooperation and prosociality and for designing effective policy measures that support these. While established laboratory-based approaches represent “gold-standard” approaches, their practicality and widespread use are limited by the restrictions involved in their implementation. In contrast, non-incentivised survey measures are simple and widely used yet remain unvalidated, leaving it unclear what they truly capture. We address this gap by validating a popular set of non-incentivised measures against incentivised benchmarks across two diverse contexts—one WEIRD (Italy) and one non-WEIRD (India)—using student and general-population samples (N≈1,400) in laboratory and lab-in-the-field environments. Every measure is validated in seven settings representing a range of interaction domains including cooperation (e.g. Public Goods Game, Dictator Game). From these results, we assemble a menu of validated survey measures, highlighting their respective strengths and offering guidance for best practice across different research contexts and constraints.
