New twin study (N=7,199) by @joshtybur shows good genetic correlation between 'disgust proneness' (thinking yucky things are yucky) and 'contamination sensitivity' (worrying about infectious diseases).
Supports the idea that disgust evolved to protect us from infectious diseaseshttps://twitter.com/sentientist/status/1257701987572871172 …

Preprint out on the behavioral genetics of disgust @joshtybur shows 54% of covariance attributable to genetic factors and no evidence for shared environment -surprisingly parent modeling likely doesn't contribute to individual differences in disgust https://psyarxiv.com/qghbc
