My very first paper has just been published in Nature Human Behaviour!

In it, we demonstrate that both a chatbot and a more traditional pedagogical intervention can help improve adolescents' knowledge of vaccines and their attitudes towards vaccination.

"From this point of view, fairness really may be a universal law."

Morality Is in Our Brain, in Our Genes, and Even in the Structure of the Universe

In defense of "Natural Law", Nicholas Baumard explains how modern scientific understanding of evolution actually supports the idea of a moral sense.

the functional form of moral judgment is (sometimes) the nash bargaining solution

new preprint👇

figure 2 from our preprint, reporting the results from two experiments

we measure moral judgments about dividing money between two parties and manipulate the degree of asymmetry in the outside options each party has

we find that moral judgments track predictions from rational bargaining models like the nash bargaining solution and the kalai-smorodinsky solution in a negotiation context

by contrast, in a donation context, moral intuitions completely reverse, instead tracking redistributive and egalitarian principles

We often hear from reviewers: "what about demand effects?" So we developed a method to eliminate them. Something weird happened during testing: We couldn’t detect demand effects in the first place! (1/8)

Summary of design and results from our three studies. (A: Design) Each study used a similar experimental design, measuring both positive and negative demand in an online experiment, with three commonly-used task types (dictator game, vignette, intervention). Our experiments had ns ≈ 250 per cell. (B: Results) Observed demand effects were statistically indistinguishable from zero. The plot shows means and 95% confidence intervals for standardized mean differences derived from frequentist analyses of each experiment and an inverse variance-weighted fixed-effect estimator pooling all experiments (solid bars). Prior measurements of experimenter demand from a previous dictator game experiment (de Quidt et al., 2018; standardized mean difference from regression coefficient) and a meta-analysis primarily including small-sample, in-person studies (Coles et al., 2025; Hedge’s g statistic) are also shown for comparison (striped bars). The main text includes Bayesian analyses that quantify our uncertainty.

Why do societies reliably develop strikingly similar traditions like dance songs, hero stories, shamanism & justice institutions?

In a new BBS target article, I propose a theory for such "super-attractors" + cultural evolution more broadly. Now open for commentary: www.cambridge.org/core/journal...

📈New meta-analysis reveals when "moral licensing" really happens. After good deeds, people act less morally only when being watched by others, not when alone. This explains why many online studies failed to replicate the effect.
