Excited to share our new paper in Cognitive Development! We replicate that children punish for both retributive and consequentialist reasons — and, surprisingly, intergroup context doesn’t change these effects. tinyurl.com/ycyhcn5a Check in out! ✨
Motivational context does not influence children’s third-party punishment in intergroup contexts
Children punish to reciprocate harm (retributive motives) and to prevent future wrongdoing (consequentialist motives). Building on this idea, we wante…

The Multi-Capital Leadership Theory - Human Nature
Human leadership and followership take many forms, shaped by the social, economic, political, and cultural contexts of our groups and societies. Underlying this complexity, we argue, are key elements of human social psychology regarding social comparison and the resolution of coordination and collective action problems. The Multi-Capital Leadership (MCL) theory posits that leader emergence and effectiveness depend on perceptions of individuals’ abilities to provide benefits or impose costs in solving challenges of group living, through the deployment of different forms of capital: material, social, somatic (e.g., physical formidability, height, immune functionality), and neural (e.g., knowledge, intelligence, personality, supernatural abilities). We integrate this framework with a review of leadership across human societies, including in non-state and non-industrial contexts, and with novel comparative analyses of ethnographic data. This synthesis highlights how context-specific demands for coordination and collective action, and the accuracy of social comparison, shape the structure and dynamics of leadership and followership across cultures.

How much do people really reject science?

New paper out doi.org/10.1177/0963...

In four studies, we asked Americans—including flat Earthers, climate change deniers and vaccine skeptics—whether they accepted basic scientific facts.

The result? A surprisingly high level of agreement. 👇

From ancient Greece to the Arabic golden age, scholars have been driven by their curiosity to investigate astronomy, history, philosophy, and sundry other disciplines. Is there a structure to that curiosity? Are astronomers as likely to also be historians or to also be philosophers?

Here's the run down of my talk at #EHBEA2025 entitled 'Analysing the Form and Function of Rituals Using Large Language Models: Fasting'. I illustrate how we can use LLMs to measure the constituent properties of rituals across ethnographic texts to test theoretical models on a large-scale.

Why do 70% of Pashtuns say that honour killings are justified?

The UNFPA estimates that 5000 women are killed every year over ‘honour’.

Is this related to cousin marriage?

Tremendous new paper, combining surveys & DNA!

Insight can arise from a wide range of experiences, from making groundbreaking discoveries to reading a whodunit. Are some people more interested in this feeling?

When doing computational conscience, I feel there are many ways to p-hack during model building. One solution to increase transparency would be to do multiverse analysis and report all possible reasonable analyses to test your hypothesis.

Do you happen to know computational papers doing that?

For a project I will soon be collecting some online survey data from participants outside US/UK and won't be able to use Prolific. Any recommendations on best providers to talk to? I've used Lucid before, but not sure what other options might be worth looking at.

In my beh sci seminar today, we explored Self-Determination Theory. Why do social psychologists focus so much on proximate mechanisms without asking why they exist? Evolutionary frameworks aren’t required, but how can the ultimate 'why' behind 'basic psychological needs' be so easily overlooked?
