What are the determinants of social choices? Why does it matter?

I am a behavioural scientist studying the evolutionary and cognitive determinants of social cognition. I have mainly focused on the way motivational factors affect people’s social behaviours. I am especially interested in the way stress, environmental harshness, and uncertainty impact a range of decisions:

- Cooperation and social trust

- Health attitudes

- Political and religious attitudes

- Parental investment

The central hypothesis behind my work is that environmental and motivational factors alter individuals’ minds in significant ways and should be targeted upstream to improve people’s lives.

In addition, I apply behavioural and cognitive insights to questions that have direct implications for public policies (attitudes towards climate change mitigation, attitude towards air pollution, health attitudes). I co-founded the Behavioural Insights Agency, which brings together researchers from JPaL, Sciences Po, ENS and the CEPREMAP, to help public administrations to design better public policies.

I'm currently at ENS, in the Laboratoire de Neurosciences Cognitives et Computationnelles (INSERM U960), where I co-lead the Evolution and Social Cognition group. I can be found on Google Scholar and Twitter.
