A quantum of self: A study of self-quantification and self-disclosure

Abstract

An increasing number of people are tracking their fitness activities, work performance and leisure experiences using body sensors (e.g., wristbands or smartwatches) and mobile applications. This trend, referred to as self-quantification, is driven by various motivations, from curiosity to a desire to improve performance. As self-quantification by means of digital devices is a new behavioural trend, the phenomenon has only recently received academic attention. Neither antecedents nor the implications of this phenomenon have been thoroughly investigated. This paper aims to address these gaps. Based on the literature on self-quantification, privacy and self-disclosure, we empirically test the relationship among personality traits, privacy, self-quantification and self-disclosure. The findings suggest that conscientiousness and emotional stability are associated with self-quantification. In addition, we find a significant effect of self-quantification on self-disclosure in the survey context, indicating that individuals who habitually use self-tracking applications and wearable devices are also more likely to disclose personal data in other contexts.
