🚨 The Economist has been telling you for years that polygamy causes civil war by locking men out of marriage. A new article with @rebeccasear.bsky.social and @anthrolog.bsky.social explains that the demography of marriage markets doesn't actually work that way. 🧵

High rates of polygyny do not lock large proportions of men out of the marriage market | PNAS

There is a widespread belief, in both the scholarly literature and the popular press, that polygyny prevents large numbers of men from marrying by ...

Are you studying animal sociality?

My (now published) first PhD chapter proposes a Bayesian + causal framework to infer the factors shaping the social relationships that animals form with one another.

A causal framework for the drivers of animal social network structure

Author summary Behavioural ecologists ask mechanistic questions about behaviour—causal questions. When studying animal societies, these questions often concern the drivers of social network structure....

New paper in NHB 📄🚨
We ran extensive experiments to show that making the rules of some canonical economic games looser, makes people more cooperative

Social networking agency and prosociality are inextricably linked in economic games - Nature Human Behaviour

Jia et al. experimentally show that when individuals can tailor their actions to each neighbour—a freedom termed social networking agency—they display higher levels of cooperation, trust and fairness in economic games.

3/ We show how generative network models provide an important tool for people in ASNA. They can handle uneven sampling and measurement issues, produce biologically meaningful estimates about network structure (not just p-values ‼️), and can flexibly incorporate other covariate data.

Daniel Redhead @danielredhead.bsky.social · Aug 4

2/ Typical methods in ASNA rely on ratio indexes (e.g., SRI, DSI) and permutation tests to deal with these dependencies, plus other issues related to imbalanced sampling. However, there’s been quite some (growing) evidence showing the pitfalls of relying on such methods.

Daniel Redhead @danielredhead.bsky.social · Aug 4

1/ ASNA often treats statistical dependencies in networks as problems to eliminate. But these dependencies are part of the biology that we’re interested in!

We show how to model them directly, not try to control them away.
