Figure 1. Association between factuality score adjusted by country mean, parties’ left-right ideology (right), and populism (middle), and government participation (left) with 95% confidence intervals.
I think this means that the y axis represents the deviation from the mean score, not the actual 'factuality score'.
A more important issue is not "fake news" but rather highly biased and tightly framed news that purports to be neutral. The hegemonic narrative is actually extremely biased but never criticized. This is completely normalized and widespread in the imperial core, especially among both flavors of politicians.
I always like the "they're both the same" people who say things like, "they would oppress queer people too if they had the power!" And then you point out that they did have the power and didn't do anything near to the level the right does and they just shoo you away like a fly.
