Study: Women view other women wearing red as a sexual threat

Pazda and his colleagues found another effect—that the women who were exposed to the photo of the woman wearing red engaged in “mate-guarding” and “derogation”; in other words, they were more likely to speak negatively about the woman wearing red (“I would guess that this women cheats on men”, “I would guess that this woman has no money”, etc.) and more likely to protect their significant others from her.
