Psychological research consistently demonstrates that stable dispositional traits, such as trait jealousy and neuroticism, are strong positive predictors of experiencing frequent romantic and sexual jealousy.
The claim posits a positive correlation between trait jealousy and the frequency of experiencing sexual jealousy. Papers [1], [8], and [10] explicitly discuss dispositional proneness to jealousy, trait jealousy, and related personality variables as antecedents and predictors of romantic jealousy experiences. No papers refute this link. Thus, the balance of evidence strongly supports the claim.
