Thrilled that we were awarded a LISS panel grant, with @rensec.bsky.social & Beate Völker! With the grant we realize survey time in the LISS panel to measure change in extended networks that include both strong and weak ties. We apply a new instrument: the network scale-up method in the panel

It combines longitudinal register data on salaries and, uniquely, matches that to survey data on PhD holders to follow their careers. This enables to precisely pinpoint how gender inequities in salaries develop after a PhD both within and outside the university.

This was a very cool paper to write and combines complicated Bayesian NSUM models and vignette experiments with a very important sociological topic – i.e., discussing politics is a vehicle to de-polarize society. Here is the open replication website to the paper: politicaltalk.netlify.app

-Homophily on gender, ethnic background, or political opinion similarity surprisingly has little effects - Whether you know someone well, and friends much more so than family, seems more important than whether you look alike
100
Bas Hofstra @bashofstra.bsky.social · 12/12/2025
🧐 What do we find? - The overwhelming majority of people in the Netherlands (>70%) disclose political opinions or engage in substantive debate - Men do so more often than women, as do theoretically educated rather than practically educated people

Bas Hofstra @bashofstra.bsky.social · 12/12/2025
🔭What do we study? - We ran an experiment with thousands of people in the Netherlands as to how they choose political discussion partners - We consider dyadic similarity and extended networks using network scale-up methodology

Knowledge lost, parity gained? COVID-19 and gender gaps in Dutch academia - Scientometrics
We investigated the extent to which the COVID-19 pandemic impacted long-standing gender inequalities in Dutch academia. Dutch academia is an ideal case to gain insight on exacerbated gender differentials due to COVID-19 on employees, because men and women face comparable institutional contexts and any COVID-19 impact becomes visible and measurable fast through potentially decreased yearly publications. We reconstructed the complete publishing careers up till 2022 of more than 8000 Dutch scientists who received a PhD from 1990 onwards and still had an active publication career before the pandemic started. We compared the publication dip between men and women during COVID-19. Our data allowed us to investigate whether the gendered impact of COVID-19 varied across research domains, different PhD cohorts and type of research output. We consistently find that COVID-19 did not have more severe consequences on research output for women than for men.

This is a key paper in the growing literature on the effects of COVID-19 on academia. It is done purely with webscraped data, and it is a showcase how you can do fine-grained analyses if you put in the work.

📖 What did we find? - During COVID-19, scientists published about 33% fewer papers - Dutch science was hit hard: “lost” around 20,000 publications - Scientists with childcare responsibilities struggled to maintain productivity - Researchers with a migration background were also hit harder

Additionally, we find a pretty strong presence for gender and educational homogeneity. These findings have important implications for Dutch social structure as to who is at risk to become socially isolated and as to where social barriers between groups exist.
