Tinder, #metoo, and cyberharassment: Evolutionary and behavioural perspectives on unsolicited sexual images

The internet has enabled the exchange of graphic, sexual images, however there is a fundamental lack of empirical research conducted on the motives for sending self-taken sexual images. The incentives are unknown, as well as the prevalence of the behaviour in general. We created a predictive model for the sending of unsolicited nude images for both men and women.

Our results suggest that, for men, this behaviour is predicted by psychopathy, self-rated mate value, and an accepting attitude towards sending nudes, whereas in women it is predicted by narcissism and a liberal attitude towards sending nudes. We conclude that female senders can be characterised as sex-positive individuals, and that male senders may have darker intentions and motives. This has implications for how this behaviour is viewed in both legal and sexual health contexts.
