For many years, studying human behaviour and the decision-making process was limited to observing the outcomes or to analysing small samples. The so-called digital revolution is offering us new data sources (such as posts on social media or health apps) and data analysis tools that make it possible to start studying the behaviour of large numbers of individuals, enabling the emergence of large-scale quantitative social research.

We are using such data and developing new methods to improve our understanding of human actions from a theoretical and first-principles perspective, with applications to science communication and public policy.
