Studying social sciences & humanities makes students more left-leaning, controlling for initial views & major preference, driven by cultural views. Implies that if all students majored in business, college–noncollege ideological gap would shrink by 1/3

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.
