I was trained as a theoretician in evolutionary biology, and I’m interested in understanding behavior, in particular human behavior, based on an evolutionary perspective. My work focuses on two major questions:
(1) Why is human cooperation universally constrained by the logic of fairness? To answer this question, I develop models in collaboration with Nicolas Baumard and Stéphane Debove. We show that, whereas pairwise reciprocity per se is undertermined (what economists call the folk theorem), the evolution of reciprocal cooperation becomes constrained by fairness principles when individuals can freely engage in a diverse range of social interactions, and choose among them.
(2) Why is reciprocal cooperation so rare among non humans but so frequent in humans? To answer this question, with the help of models, I show that reciprocal cooperation is not a regular form of adaptation that can evolve by natural selection. Rather its evolution, like the evolution of communication, requires the recycling of functions evolved intially for a different purpose. I’m interested in showing how this constraint explains both the rarity of reciprocal cooperation among non-humans, and the form that it takes in humans.
I am interested in using evolutionary and psychological approaches in the social sciences, in particular in economics.
More specifically, I use:
- Biological market theory to explain why moral judgments and cooperative behaviors are based on considerations of fairness;
- Life-history theory to explain behavioral variability across culture, history, social classes and developmental stages;
- Dual process theory to explain the content of human reflections and religious thinking (in particular on morality and gods);
- all of the above to explain why some public policies naturally work better
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 cognition. More recently I have worked on the way stress, environmental harshness, and uncertainty impact a range of social and non-social decisions:
- prosociality and social trust
- political attitudes and religion
- health attitudes, fertility and parenting
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.
I am an evolutionary and cognitive psychologist working on the function and workings of reasoning. With Dan Sperber, we have developed the argumentative theory of reasoning, which offers a new function for human reasoning: to find and evaluate arguments so as to convince others and only be convinced when it is appropriate. I also study the cognitive mechanisms with which people evaluate communicated information.
I am interested in the cognitive mechanisms underlying social and political behaviour, notably leader choice and cooperation. In particular, I adopt an ecological and evolutionary approach to better understand the inter-individual differences in these domains, across both space and time. To do so, I rely on behavioral data, social surveys, computational modeling and, more recently, cultural artifacts such as paintings and books.
I am a cognitive neuroscientist interested in explaining social cognition, and in particular conformism, using evolutionary lense. My project in the Evolution and Social Cognition aims at using life-history theory to study how risk-taking explains inter-individual variability in social learning.

I am interested in using nudges and behavioural approaches more generally to promote sustainable behaviour and cooperative behaviour in Paris. I'm interested in applying both economics and psychology to produce more efficient public policies.
I'm interested in the evolution of cooperation. I am using evolutionary robotics as a modelling and simulation tool in order to introduce a more realistic genotype to phenotype mapping.
Fascinated by apparently irrational beliefs and behaviors, I study the cognitive mechanisms underlying information transmission and evaluation. I try to predict what type of information is more likely to be accepted, transmitted, and memorized. Additionally, I’m working on new techniques of counter-argumentation to change people’s minds efficiently.
I am interested in understanding evolutionary bases of human social behaviors. More specifically I study local adaptations in behaviors. My beginning PhD is about the evolution of social trust throughout History based on the trustworthiness of figurative portraits.
I am trained in social and evolutionary psychology. Therefore, I am interested in explaining social phenomena from an evolutionary perspective. I am particularly interested in human cooperation, morality and mismatch theory. Currently I am using life-history theory to explain human variability in cooperative behavior.
I’m interested in the cognitive adaptations underlying the emergence of human social and moral norms. In particular, I am currently working on the cognitive and evolutionary roots of the cross-culturally recurrent intuitions about moral purity.
I am currently studying the cognitive and evolutionary determinants of individual interest for environmental issues and motivation to engage in pro-environmental behaviour . I'm interested in the application of behavioural sciences to produce more successful public policies, especially in the domain of sustainable development.

I am interested in understanding the determinants of consumption and in particular materialism. Are individuals who are exposed to harshness, unpredictability or inequality as children more likely to have materialistic values later in life? If we want people to reduce their consumption for environmental reasons, it is useful to understand what are factors of consumerism.
I am postdoctoral researcher for the FRONTSEM ERC project (directed by Philippe Schlenker, in collaboration with Emmanuel Chemla and Klaus Zuberbühler) and I work on the semantics of primate alarm calls
I am interested in how psychology can help to better understand and to improve institutions. Particularly, I am studying how advances in decision-making science can inform public policy in general and the institutional design of the judicial system.
