Media literacy tips typically encourage people to be skeptical of the news despite the small prevalence of false news in Western democracies. Would such tips be effective if they promoted trust in true news instead? A pre-registered experiment (N = 3919, US) showed that Skepticism-enhancing tips, Trust-inducing tips, and a mix of both tips, increased participants' sharing and accuracy discernment. The Trust-inducing tips boosted true news sharing and acceptance, the Skepticism-enhancing tips hindered false news sharing and acceptance, while the Mixed tips did both. Yet, the effects of the tips were more alike than different, with very similar effect sizes across conditions for true and false news. We experimentally manipulated the proportion of true and false news participants were exposed to. The Trust and Skepticism tips were most effective when participants were exposed to equal proportions of true and false news, while the Mixed tips were most effective when exposed to 75% of true news - the most realistic proportion. Moreover, the Trust-inducing tips increased trust in traditional media. Overall, we show that to be most effective, media literacy tips should aim both to foster skepticism towards false news and to promote trust in true news. Media literacy tips promoting trust in true news, skepticism of false news, or a mix of both, were all effective in improving discernment between true and false news stories relative to a control condition without tips.
