Le «Prix senior Maurice Chalumeau 2020» a été décerné à Léïla Eisner, pour la thèse de doctorat en psychologie sociale qu’elle a soutenue à l'Université de Lausanne, sous le titre:

Social change and perceived societal norms: An application to the sexual minority context in Switzerland 

This thesis aims at providing a better understanding of when and why people misperceive others’ opinions toward LGBTIQ+ issues, the impact that these misperceptions have on their willingness to act up for social change, and the impact of new laws on perceptions of the status quo. To achieve this goal, Léïla Eisner gathered representative data of the population in the canton of Vaud using the random-route method, initiated a large-scale LGBTIQ+ national survey that is now part of the Swiss LGBTIQ+Panel, and investigated the impact of a new law on step-child adoption on individuals.
This research does not only have a strong impact on the scientific community, but also on LGBTIQ+ individuals and the wider society.
