Happy to share a new paper led by the terrific Anzhi Sheng. We find that allocation policies that promote cooperation tend to concentrate benefits among the well-connected. And so structured societies must weigh collective success against the inequality it generates. www.nature.com/articles/s41...

Cooperation conflicts with equality when allocating public goods

Anzhi Sheng, Qi Su, Alex McAvoy, Long Wang & Joshua B. Plotkin
Nature 655, 1217-1225 (2026)

Cooperation is typically seen as the ideal outcome in a social dilemma. Because cooperators are vulnerable to exploitation, much of the literature has focused on mechanisms, such as spatial structure, that support prosocial behaviour and the production of public goods1,2,3,4,5,6,7,8,9,10,11. Yet the rules for distributing these goods also shape behaviour and long-term prosperity. Here we study policies for allocating public goods, comparing equitable allocation, in which returns are proportional to potential contributions, with uniform allocation, in which all individuals receive equal shares. For most social networks, we find that uniform allocation facilitates the spread of cooperation compared with equitable allocation. But this success comes with a cost. Uniform allocation concentrates resources in a small number of highly connected individuals12, whereas peripheral individuals receive fewer benefits and may even be worse off than in a non-cooperative society. We develop a theoretical analysis of the tension between cooperation and equality, and we identify this conflict across diverse empirical social networks. Our results show that inequality may be an unavoidable consequence of allocation policies designed to foster cooperation in spatially heterogeneous populations. The question of how to promote cooperation is therefore incomplete: because policies that facilitate cooperation can also generate social stratification, we must weigh the benefits of cooperation against the inequality that accompanies it.

Learning from the most successful people makes sense? We show that social learning, and especially payoff bias, is bad when choice outcomes are dependent on prior success💰 As such "rich-get-richer" dynamics are everywhere, this shows fundamental boundary conditions for the benefits of SL!

A Demographic Theory of Similarity-Biased Social Learning. Now out in PNAS, led by the incomparable @apvelilla.bsky.social . We use modeling to explore conditions for the (cultural) evolution of parochial (and anti-parochial) learning biases. www.pnas.org/doi/10.1073/...

Humans adapt by learning from others, but risk acquiring maladaptive behaviors when learning from individuals facing different conditions. We present an evolutionary model exploring how individuals use social identity markers to select learning targets in diverse populations. Learners evolve biases that track reliable information sources: preferring similar individuals when in-group knowledge is adaptive, and dissimilar individuals when in-group behaviors are disadvantageous. Our framework demonstrates that this adaptive bias makes social learning viable even when it is costlier than individual learning. Additionally, we show that a minimum threshold of reliable cultural information is required for social learning to spread, providing a mathematical explanation for how demographic diversity drives population-level patterns of cultural segregation and assimilation.

I wasn't able to attend #CogSci26 this year, but happy to share that a paper I presented there two years ago is now published in journal-length form 😊 The paper studies how people can rationally infer others' goals in open-ended spaces, and yet do so rapidly and spontaneously.

Original Article
Open Access
Infinite Ends From Finite Samples: Open-Ended Goal Inference as Top-Down Bayesian Filtering of Bottom-Up Proposals
Tan Zhi-Xuan, Gloria Kang, Vikash Mansinghka, Joshua B. Tenenbaum

Open-ended goal inference as top-down Bayesian filtering of bottom-up proposals. We model inference in open-ended goal spaces as the combination of two processes: (a) Bottom-up sampling—you (observer) see your friend (agent) enter the kitchen and come up with several plausible goals (making tea, getting a snack, grabbing drinks, checking the pot, and so on) based on the context cue that your friend is in the kitchen. (b) Top-down filtering—your friend opens the fridge, which would be irrational if they were making tea or checking the pot; these goals are hence filtered out as poor explanations. By repeating these processes as actions unfold, we can model how people draw broadly rational inferences about others' goals even when the space of possibilities is infinite or just too large for explicit enumeration.

I really like this paper I did with @nathan-gabriel.bsky.social and @avbell.bsky.social, now out in EHS. It's an unusual paper because we tried to model the emergence of complex, multidimensional and intersectional identity structures from a signaling perspective. www.cambridge.org/core/journal...

The evolution of identity signals for co-ordination in diverse societies
Individual social identities indicate group affiliations and are typically associated with group-typical preferences, signals that indicate group membership, and the propensity to condition actions on the social signals of others, resulting in group-differentiated interaction norms. Past work modelling identity signalling and co-ordination has typically assumed that individuals belong to one of a discrete set of groups. Yet individuals can simultaneously belong to multiple groups, which may be nested within larger groupings. Here, we introduce the generalized Bach or Stravinsky game, a co-ordination game with ordered preferences, which allows us to construct a model that captures the overlapping and hierarchical nature of social identity. Our model unifies several prior results into a single framework, including results related to co-ordination, minority disadvantage, and cross-cultural competence. Our model also allows agents to express complex social identities through multidimensional signalling, which we use to explore a variety of complex group structures. Our consideration of intersectional identities exposes flaws in naive measures of group structure, illustrating how empirical studies may overlook some social identities if they do not consider the behaviours that those identities function to afford.

Figure 1.

We recover many empirical results and generate new hypotheses:

Poor people may be slower to adapt to environmental change, creating the appearance of “poverty traps”
