International Collaboration on the Social & Moral Psychology of COVID-19
At the peak of the Covid-19 pandemic, more than 200 researchers joined their forces behind Jay Van Bavel to run the biggest international collaboration in social and moral psychology ever. I was team leader of data collection in France, as well as Morocco and Senegal, which were among the very few African countries covered. The three papers and the scientific blog post below emerged from this large-scale collaboration. The website of the international collaboration is here.
