The present study examined the link between neuroticism, extraversion, as well as presentation of the real, the ideal, and the false self on Facebook. Self-reports were collected from 261 young adults (ages 18–30) about personality, online self-presentation, and Facebook use. Level of extraversion was positively associated with Facebook activity level. A series of regression analyses revealed that young adults high in neuroticism reported presenting their ideal and false self on Facebook to a greater extent whereas those low in extraversion reported engaging in greater online self-exploratory behaviors. Findings suggest that young adults who are experiencing emotional instability may be strategic in their online self-presentation perhaps to seek reassurance, and those who have self-doubt further explore their self online.
