No. The average Democracy Index of Western Europe is 8.05 (full democracy), while the US scores 7.65 (flawed democracy, trending downwards). Just below Poland, just above Botswana.

You might shrug and say "well pobody's nerfect", but the disparity between the American narrative and the reality is actually quite extreme.

I don't think this index holds much value TBF.

Look at the what The Economist is and promotes. I'd have about as much trust in Faux News Independent Press index.

I used to work and live in Poland for almost a decade (I visit friends there often), and I live and work on the UK and to be fair Poland seems far more democratic. Actual independence of the Judiciary, proportional representation Parliament, vacatio legis (as opposed to UK's "hey, that's your new tax code, effective immediately"), growing local democracies (despite 50 years of Soviet occupation, thanks to the betrayal from the West).

Is the index measuring how wealth distribution minimize disparity? How policies debates are driven by spontaneous needs from general public, and how solutions are proposed and refined through open to everyone debates, how programs (not some random face) are voted be it as whole or per compatible submodules? How imperative mandate are dully applicated and how any tentative of corruption is punished with several years of being forbidded of taking any mandate?

That index is a product of the institute itself. Funded by non democratic values. Worthless junk / progoganda piece if you ask me.
