What people learn from punishment: A cognitive model

Date: Friday, Oct 10
Time: 15:00 UTC+2 Vienna / 9 am NYC

Sign up: list.ku.dk/postorius/li...
Abstract: Authorities, from parents of toddlers to leaders of formal institutions, use punishment to communicate disapproval and enforce social norms. However, punishment is often interpreted in contrasting ways: at times it teaches and enforces norms, but at other times it fails or even backfires, undermining the authority’s legitimacy. We show that these seemingly contradictory effects of punishment can only be understood by considering the cognitive processes in the minds of human observers of punishment. In a series of experiments, we showed the systematic variability in how adults and children interpret punishment. We developed a formal cognitive model, derived from a standard model of how people make sense of each others’ actions (Inverse Planning), that captures and explains these inferences quantitatively and parsimoniously. This work reveals the rational logic behind how people learn from punishment, and a key constraint on the function of punishment in establishing shared social norms.

I had the great pleasure of spending the past week with Jörg Gross’s group in Zurich. Inspiring conversations, exciting projects, and a wonderful atmosphere throughout. Zurich itself was absolutely stunning.

Added 3 slides to my "dear students, don't use LLMs" slidedeck. Here's how it works:

1. Generated map of <our country/city> from prompt "Generate an image: a schematic map of the <X> with major roads, cities, and landmarks."
Discuss how obviously wrong it is. Very fun, many lolz, silly LLM. 🤣

When asked who beyond my immediate circle has shaped my thinking the most, I often point to two names: Toshio Yamagishi and Gary Bornstein. It was an honour for me to write this short piece to pay tribute to Bornstein's classic work on intergroup conflicts.

Overcoming the social dilemma of climate change

Friday, Sep 26, 15:00 UTC+2 Vienna / 9 am NYC

Sign up: list.ku.dk/postorius/li...
Abstract: Mitigating the increasing threat of climate change poses a uniquely challenging cooperative problem. Multiple strategic features of climate change impede coordinating around successful action. For example, there is uncertainty about the timing and dynamics of climate change impacts. Different actors vary in their historic contribution to the problem and vulnerability now. There are many solutions available to mitigate climate change, but they differ in their effectiveness and probability of success. And, compounding all of this, there are asymmetries in information between elite decision-makers and the publics that they govern. In this talk, I argue economic games are well-suited to understand both how these strategic features delay successful climate action and provide insights into how to overcome these problems through public policy. Focusing on the case of governing emerging mitigation technologies, I will present the empirical evidence that people are willing to pay costs to avert climate disaster. While mistrust between the public and policymakers erodes cooperation, I will also present solutions that emerge from these experiments. I conclude by discussing how insights from the lab can inform real-world messaging and policymaking to encourage successful climate change mitigation.

My PhD student @qinyuxiao.bsky.social has written a wonderful tribute to Gary Bornstein’s influential paper on team games (doi.org/10.1207/S153...) — a paper that remains as relevant today as it was over 20 years ago. You can read Qinyu’s short piece here: doi.org/10.1038/s441...

Normative expectations of reciprocal negotiators

Friday Sep 12, 14:00 UTC+2 (Vienna) / 8 am NYC

Sign up: list.ku.dk/postorius/li...
Abstract: This paper develops a theoretical framework to examine how normative expectations--what one considers others should do based on their fairness perceptions--in shaping the behavior of players with reciprocal preferences in a public goods game. Standard reciprocity models typically assume uniform, exogenously determined, and moderate expectations. By contrast, I allow players to (i) vary in how demanding they are of others, (ii) disagree about what counts as fair, and (iii) form self-centered normative expectations endogenously. In noncooperative play, strong reciprocal concerns transform the payoff structure from a material payoff dilemma into a coordination game in utilities, with one exception. In coalition formation, three central results emerge: (i) the empty coalition is always stable, (ii) the grand coalition becomes stable once reciprocal concerns are sufficiently strong, and (iii) partial coalitions can be stable under specific conditions. Exogenous expectations create distinct effects on cooperation: lower expectations facilitate the stability of the grand coalition, whereas higher expectations increase the size of partial coalitions, potentially leading to a majority coalition. This latter finding is more consistent with empirical observation.
