Did you actually read what you quote? It aligns with what I said - Chinese feel mostly satisfied with their government and don’t want the democracy, and don’t feel that their government is democratic. Claiming that Chinese believe that their country is democratic is not what Harvard did in the document that you’ve provided.
Regarding “not only possible but likely”: please do the math. If the share of population believing in X is 90%, the chance that none of the five selected people do X is (1 - 0.9)^5 = 0.001% (i.e., 1 in 100,000), assuming independence across people. That’s what you call likely?
PS. Why is this always the .ml instance 😀
Poland has no nukes. Russia does. If Poland were to somehow march to Moscow and the threat was real, Poland would cease to exist
