Résumé : People tend to believe that their internal states are transparent to others (e.g., illusion of transparency), and even more when they are self-centred. Would it be the case for narcissistic individuals who are highly self-centred? Three studies investigated whether narcissists feel more transparent because they are egocentric, or whether they feel less transparent because they are socially skilled. Using a vignette method, Study 1 showed that the more participants were narcissists, the less they felt transparent with regard to their emotions, values and behaviour. Study 2 further showed that this association was stronger when narcissistic characteristics were valorised. In addition, the negative link between narcissism and felt transparency was mediated by self-monitoring. Using a face-to-face interaction, Study 3 provided evidence that participants high on narcissism were less prone to illusion of transparency. Overall our studies suggest that narcissists’ meta-perception is more accurate, less egocentric because they are socially skilled.
