This article discusses the fear of missing out (FOMO) on rewarding experiences, an important psychological construct in contemporary times. We present an overview of the FOMO construct and its operational definition and measurement. Then, we review recent empirical research on FOMO's relationship with levels of online social engagement, problematic technology and internet communication use, negative affectivity, and sociodemographic variables. Additionally, we discuss theoretical conceptualizations regarding possible causes of FOMO and how FOMO may drive problematic internet technology use. Finally, we discuss future directions for the empirical study of FOMO.

Understanding individual differences in attitudes towards Artificial Intelligence (AI) is of importance, among others in system development. Against this background, we sought to investigate associations between personality and attitudes towards AI. Relations were investigated in samples from two countries—Germany and China—to find potentially replicable, cross-culturally applicable associations. In German (N = 367, n = 137 men) and Chinese (N = 879; n = 220 men) online surveys, participants completed items on sociodemographic variables, the Attitudes Towards Artificial Intelligence (ATAI) scale, and the Big Five Inventory. Correlational analysis revealed among others significant positive associations between Neuroticism and fear of AI in both samples, with similar effect sizes. In addition to a significant association of acceptance of AI with gender, regression analyses revealed a small but significant positive association between Neuroticism and fear of AI in the German sample. In the Chinese sample, regression analyses showed positive associations of acceptance of AI with age, Openness, and Agreeableness. Fear of AI was only significantly negatively related to Agreeableness in the Chinese sample. The association of fear of AI with Neuroticism just failed to be significant in the regression model in the Chinese sample. These results reveal important insights into associations between certain personality traits and attitudes towards AI. However, given mostly small effect sizes of relations between personality and attitudes towards AI, other factors aside from personality traits seem to be of relevance to explain variance in individuals’ attitudes towards AI, as well.

Health anxiety has been linked with fear and anxiety regarding COVID‐19. Higher levels of health anxiety likely increased social distancing and self‐isolating during the pandemic. We investigated relations among health anxiety, fear of missing out (FOMO) on rewarding social experiences from social distancing, and consequential levels of problematic smartphone use (PSU) and gaming disorder (GD). We surveyed a broad sample of 812 U.S. and Canadian participants during the pandemic, in late‐May 2020, using the Short Health Anxiety Inventory, FOMO Scale, Smartphone Addiction Scale‐Short Version, and GD test. Significant bivariate relationships were found among health anxiety, FOMO, PSU, and GD severity. Using structural equation modeling, FOMO mediated relations between health anxiety and both PSU and GD severity. We discuss FOMO as an important variable explaining problematic digital technology use to compensate for unmet social needs from social distancing. We discuss these findings within the context of the Interaction of Person‐Affect‐Cognition‐Execution theoretical model of problematic internet use. Results offer novel insight into the role of health anxiety on FOMO from unmet social needs during the COVID‐19 pandemic, and consequential problematic internet use.
