New paper out now! We (w/ @rmcelreath.bsky.social and @gregork.bsky.social) start from the observation that among adolescents in Leipzig, the gender gap in life satisfaction has doubled over time and ask: why?> link.springer.com/article/10.1...

Why Did the Gender Gap in Adolescent Life Satisfaction Grow? Evaluating Methodological and Demographic Explanations

The city of Leipzig in Germany conducts large-scale school surveys of adolescents in secondary schools. While in 2010 and 2015 girls were somewhat less satisfied than boys, in 2023 this gender gap had doubled. Why? When asking such a reverse causal question, answers often focus on broad narratives, such as the psychological impact of social media. Here, we illustrate how to probe alternative explanations, such as demographic changes and methodological issues. First, we rule out that the observed pattern is a simple scaling artifact. Second, we find that the widening of the gender gap is much more pronounced among students with a migration background. This could plausibly be explained by a shift in the composition of the underlying population, with a strong increase in the proportion of Syrian students, and a relative decrease of Vietnamese students. Third, part of the increasing gender gap could potentially be attributed to survey mode: In 2023, for the first time, the survey was conducted on tablets—and unexpectedly, girls (but not boys) reported significantly lower satisfaction when surveyed on tablet rather than on paper. Lastly, beyond these patterns, we still find significantly widening gender gaps in satisfaction with leisure time activities and relationships to friends. Thus, there may be a substantive increase in the gender gap in satisfaction in those two domains that is not readily attributable to changes in demographics and survey mode.

Plot showing mean life satisfaction among female and male adolescents over time. In general, boys show higher levels than girls; from 2010 to 2015 the lines for the two genders are pretty much parallel. In 2023, both boys and girls decline -- but girls much more so, effectively doubling the gender gap.

“we are trapping 21st-century minds inside 19th-century academic hierarchies.” This essay gets a lot right about problems with German science. I would add that the hierarchies and precarious contracts lead also to systemic abuse and scientific misconduct. open.substack.com/pub/realimag...

Germany does not lack talent, and it does not lack funding. But we are trapping 21st-century minds inside 19th-century academic hierarchies. We are asking brilliant young scientists to build the future of the German economy, but refusing to give them the lab space, the job security, or the scientific independence to actually do it. If we want to reclaim our place as an industrial superpower, we have to stop the rat race of trying to keep every technology and structure alive that made us successful in the 20th century. Instead, we must fix our system that pushes our most ambitious scientists away. The money is there. The talent can be there. Now, we also need the courage to fix what’s broken.
