📢Can free academia withstand democratic backsliding? Why some universities wither while others survive. Read the recently published article in #ISPR. Together with Katrin Kinzelbach and @silindberg.bsky.social (Open Access): doi.org/10.1177/0192...

We find an average treatment effect of a 20% decline in research performance when academic freedom declines substantially. But we do not find any statistically significant effect on the top 10% or top 1% publications, as measured by citation counts in their subject category and publication year. 8/

We found a positive and statistically significant effect of the ‘between AF’ variance on bibliometric indicators with a pooled effect size of 1.7969 (95%-CI = 1.4647; 2.1290]). ‘within AF’ has a positive pooled effect size of 0.0266 but is statistically not significant at conventional levels. 5/

Is research performance related to academic freedom? A preprint co-authored with @lutzb.bsky.social conducts a large-scale empirical analysis on the national level to this question. osf.io/2mh8f #academicfreedom #AcademicFreedomIndex Short 🧵
