The Ability to Judge the Romantic Interest of Others

Abstract

The ability to judge another individual's ro- mantic interest level—both toward oneself and toward others—is an adaptively important skill when choosing a suitable mate to pursue. We tested this ability using videos of individuals on speed dates as stimuli. Male and female observers were equally good at predicting interest levels, but they were more accurate when predicting male inter- est: Predictions of female interest were just above chance. Observers predicted interest successfully using stimuli as short as 10 s, and they performed best when watching clips of the middle or end of the speed date. There was consid- erable variability between daters, with some being very easy to read and others apparently masking their true intentions. Variability between observers was also found.
