“…According to contemporary wisdom, political knowledge “promotes political participation” (Galston, 2001, p. 224), and the same applies to internal political efficacy, as many studies report a positive impact of political efficacy on a range of political activities (Balch, 1974; Steinbrecher, 2009; Vecchione et al, 2014; Verba, Schlozman, & Brady, 1995). While much empirical research was concerned with voting behaviour, showing that political knowledge increases the likelihood to vote (e.g., Amadeo, Torney-Purta, Lehmann, Husfeldt, & Nikolova, 2002; Delli Carpini & Keeter, 1996; Howe, 2006; Krampen, 2000b), research has also focused on other kinds of political participation, however. On the one hand, scholars find the influence of political knowledge to be smaller with respect to other political activities (Milner, 2007; Oesterreich, 2003), and others even suggest that internal political efficacy might be the more robust predictor of unconventional political activities in comparison to the impact of political knowledge (Kuhn, 2006; Schulz et al, 2010).…”
