That's why I called it "relative". (and it's not applied to nations, but to governments and government policy, which can cange with time - our social democrats lost so much of their previous social-liberal profile during the last years of grand-coalition, it's not even funny)
It's still overly simplified and an average of several policies, so a very liberal government who "just" has the death penalty on the smallest crimes wouldn't end up that badly.
You might think the UK is not that "authoritarian".
The relative honesty of a news outlet, it's willingness to omit certain facts and/or overrepresent other facts, and its propensity to try to push an agenda though, are somewhat more linear.
Unless you arrive from Germany (standing an hour in line at the EU passport queue, where in Frankfurt, Athens, Paris, Bukarest they just wave you trough) to live there and notice all the CCTV everywhere. Literally everywhere. And you "know it's just for your own good and your protection"

Even the commie dictatorship I was born in wasn't able to surveil you in that detail, since surveillance was still done by people and technical means where limited.
Then there's policies about basic human rights, , same gender marriage, etc. etc.
