The tendency to cancel appointments at short notice in favor of supposedly better alternatives is referred to as “social zapping”. Social zapping is positively associated with maximizing tendencies and problematic social networks use. However, empirical investigations on which additional personality characteristics predict social-zapping behavior are yet missing. In this study, a sample of N = 190 adults performed a questionnaire-based survey assessing different personality facets and social zapping tendency. Measures included the Dark Triad - Dirty Dozen scale, Barratt Impulsiveness Scale, Maximization scale, Pure Procrastination Scale, Fear of Missing Out (FoMO) scale, and the Social Zapping Scale. On a bivariate level, social zapping correlated positively with all other measures except for trait FoMO. The results of the multiple regression analysis showed that social zapping was mainly predicted by two dimensions of the Dark Triad, i.e. Machiavellianism and narcissism, as well as attentional impulsivity and the timeliness dimension of procrastination. Based on the results, social zappers can be characterized as individuals who tend to make self-serving and/or impulsive short-sighted decisions at the expense of others. Social zapping is a phenomenon of inherent self-interest, where individuals cancel appointments spontaneously (at the last minute) with others to pursue options they deem best for themselves.
