 These observers correctly identified to what degree said interviewees were socio-sexual, even when controlling for the physical attractiveness of the person being interviewed.Another set of studies found that observers were able to reliably judge how likely it was for a man to sexually harass women he encountered by showing the observers a short, silent clip that lasted less than three minutes of him being interviewed by an attractive woman.Additional research has examined how reliably observers can estimate if individuals are in a romantic relationship.
