“…In sum, the expectations about SNS in general are mixed and this is also reflected in the literature. Whereas some studies found positive effects of social network use (Beam, Hutchens, & Hmielowski, 2016;Lee & Oh, 2013;Yoo & Gil de Zúñiga, 2014), others found negative or null effects (Dimitrova et al, 2014;Gil de Zúñiga, Weeks, & Ardèvol-Abreu, 2017;Lee et al, 2017;Shehata & Strömbäck, 2018). Besides differences in research design (i.e., ability to disentangle causality) or operationalizations of knowledge, the contradictions in findings may partly relate to the measurement of independent variables (Ohme, 2018): Logically, general time measurements yield less positive findings than those measurements that tap the intention to acquire information online.…”
