Research examining victimization risk has demonstrated that personality variables like psychopathy may be advantageous in accurately predicting vulnerability from behaviour (Book et al., 2013). There is evidence suggesting certain behaviours and personality traits may be associated with vulnerability to victimization (Ellrich & Baier, 2016; Hall et al., 2006). The current studies aimed to assess differences in behaviours (verbal/nonverbal) in relation to perceptions of vulnerability (Study 1). Additionally, it examined the role of psychopathy and gender in accurately predicting perceived future vulnerability, and the use of behavioural cues in making vulnerability predictions (Study 2). Results from Study 1 suggest people with neurotic traits view themselves as more vulnerability to future sexual victimization, and women (vs. men) feel more vulnerable to victimization. Study 2 indicates those scoring higher on psychopathy make less accurate vulnerability predictions, and use more behavioural cues to predict vulnerability. Implications and future research avenues examining vulnerability are discussed.
