Come join this exciting workshop on social network analysis and social transmission, all within a Bayesian framework!! 💻

And many thanks to @danielredhead.bsky.social and @mchimento.bsky.social for conducting it, I'm looking forward 🤩

Did cooperation evolve because of conflict? Or is conflict an (avoidable) ‘by-product’ of evolved capacities to cooperate. I think the latter—>

Retraction Watch has covered the problem of the “national IQ” database. Should be noted I’m far from alone in working to remove these publications. The spreadsheet of pubs which use NIQ - linked to in the article - was started by @kohngregory.bsky.social; a project also worked on by Cathryn Townsend

Inferring the causes of animal social network structure from time-series data Behavioural ecologists aim to understand the causes of animal social structure. Connecting theoretical models of social structure with empirical observations remains, however, a for-midable challenge....

New Paper!

A chapter of my dissertation looking at the time dynamics of friendship has been published! We find decreasing emphasis of demographic characteristics over time, in favour of friendships based on interests. Interesting implications on clustering!

"Models casting egalitarian societies as crucibles of equality perpetuate the factually uninformed notion that foragers are somehow more noble. Critiques portray egalitarianism as romantic fantasy. Neither characterization is wholly justified."

Social behaviour happens over time - so we can gain insights if we analyse it as it happened:

Behavioral data can be very detailed but are usually aggregated and normalized in ways that smother the dynamics. Ben wrote a continuous-time Markov model to improve on this, and also wrote simulations for exploring and validating pipelines. All the code is here: github.com/BenKawam/ASN...

Each dyad (a, b) moves through four discrete states over time, represented by coloured circles. The dyad remains in a given state for a certain duration, or "holding time", before transitioning to a new state according to state-specific transition probabilities, indicated by arrows showing all possible (non-zero) transitions.

New paper!

We propose a framework to empirically study animal social relationships by modelling social network (SN) data as time-series—that is, without the need to aggregate them over time.

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.

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.

We ran extensive experiments to show that making the rules of some canonical economic games looser, makes people more cooperative

Are you studying animal sociality? Confused about the "non-independence" of social network data: what on earth are they? are they threatening your results? should you attempt to get rid of them?
