(The last image isn't from Leiden — it's a photograph of mine from Prague. On a post about romantic love, it felt like it belonged.)

Special thanks to the wider project team at IJN (@edgardubourg.bsky.social, Arman Prangere, Charles Planque, Zoé Zhong Ying, Valentin Thouzeau), and to Kristoffer Nielbo & Nicolas Legrand at CHC Aarhus for the support that made both this work and this trip possible.

I presented preliminary results from an ongoing project on the variation of romantic love through history in France using the tools of computational humanities within a behavioral ecology framework.

Joint work w/ Nicolas Baumard & collaborators at Institut Jean Nicod (ENS, PSL).

Abstract:
Most research on social media considers them as supports for transmission of information, explaining online success (and pathologies) by focusing on consumers’ biases and interests. This article takes a different perspective, applying ideas from an ecological approach to culture to social media informational dynamics. It argues that success online depends both on the intrinsic appeal of content to receivers and on how well content serves producers’ strategic goals within the constraints and affordances of specific platforms. These goals include reputation management, coalition building and identity management, and coordination or participation in shared activities. Transmission is often a by-product of these motivations, and replication fidelity plays a limited role compared with transformations that adapt content to local incentives. Finally, the article suggests that platforms and communities can be understood as distinct ecological niches, each characterised by different audience structures, affordances, metrics, and algorithmic pressures. This perspective offers novel insight to persistent debates on social media dynamics, such as misinformation, radicalisation and polarisation, and the reasons behind online success.

Are there ways to fit agent-based models (ABMs) to empirical data and compare models, as we do in computational (cognitive) neuroscience?

I highly recommend this summer school to anyone looking to deepen their knowledge at the intersection of machine learning and probabilistic modeling — and to meet wonderful, kind people. Huge thanks to the organizers and to everyone I had the pleasure of meeting!

I had the chance to explore the work of fellow participants and to dive deeper into inference algorithms I’ve been using over the past few years.

What are some equations or modeling approaches that are from different communities and are applied to different phenomena but you find them similar, the same, or very similar?
Example: a paper showed how replicator dynamics in evolutionary models are somewhat isomorphic with Bayes equations.

If you could recommend a book or article from your discipline/specialty in cognitive science, artificial intelligence, or evolutionary anthropology for 2024 trends, what would it be? Looking forward to your suggestions!

My internships at RITMO, associated with the University of Oslo, gave me hands-on experience in various research methods, including mobile and stationary eye-tracking and motion capture. Before my academic journey, I dabbled in music production and collaborated with artists.
