Dokoni naučnici su pre desetak godina radili istraživanje i utvrdili da muškarci iz siromašnijih i nižih društvenih slojeva u principu više vole velike grudi kod žena.
A study published in the journal Archives of Sexual Behavior in 2013 found that men with lower socioeconomic status were more likely to prefer women with larger breasts. The authors suggested that this preference might be tied to perceptions of resource abundance, where larger breasts are seen as a sign of better nutrition and health. Research has also investigated how personality traits relate to breast size preference. For example, a study published in the journal Personality and Individual Differences in 2017 found that men who preferred larger breasts tended to score higher on traits associated with sexism and objectification of women. In contrast, men who preferred smaller breasts were more likely to value emotional connection and intelligence in a partner.
