This paper by Dominika Perdoch Sladká and Martin Kreidl (2025) re-investigates the association between sexual disagreements and union instability in light of traditional gender ideologies, which suggest that such disagreements should be more strongly linked to instability among men than among women. Previous research on this topic relied primarily on a single U.S. panel survey initiated in the late 1980s and produced inconsistent findings. Using data from the Generations and Gender Survey, a more recent longitudinal study of 19,446 individuals (43.3% men, 56.7% women) in mixed-sex partnerships across seven European countries, the authors re-examine this relationship. The results indicate that sexual disagreements are more strongly associated with separation proneness among women than among men. These findings contradict expectations derived from traditional gender ideologies and suggest that the role of sexual disagreements in union instability departs from conventional assumptions.
