Does news literacy help combat misinformation? The interplay of news literacy, political ideology, and ideological media use on COVID-19 misperceptions

The COVID-19 pandemic heightened the urgency of working across lines of political difference to combat misinformation. This paper asks: Does having news literacy matter in reducing misperceptions, and importantly, for whom does having news literacy matter? Using a national survey of US adults (N = 1700) that included the largest set of COVID-19-related misperceptions examined to date (k = 84), we tested how the effects of news literacy on misperceptions vary across ideology and ideological media consumption. Although holding a higher level of news literacy is associated with fewer misperceptions in general, it helps conservatives less than it helps liberals. Moreover, although news literacy is associated with mitigating the misperception-inducing effect of ideological media consumption on both ends of the political spectrum, this potential benefit appears to be weaker for conservative media use than for liberal media use. Finally, the benefit of having news literacy is maximized among cross-cutting consumers of ideological media but dampened among like-minded consumers, particularly conservatives with heavy conservative media consumption. We discuss the implications of our findings for identifying subgroups for future news literacy interventions and understanding the potentials and challenges of using news literacy to combat misinformation in a polarized climate.
