There is no way to “align” human brains to your preferences. The Soviets tried it, the Chinese tried it, the Americans tried it. Nobody succeeded. The best you can do is attempt to sway the masses, but you’d better rely on positive messaging, because mass culture’s failure modes are even scarier than small subcultures.
Attempting to stamp out competing worldviews leads a certain kind of (relatively common) person to dig even harder for forbidden knowledge. If you’re not careful this will lead people directly to the arms of your geopolitical enemies, as it’s not possible to fully stamp out their narratives—they have a big budget!
You can’t escape fringe beliefs, but admittedly it seems like there were fewer of them in the USSR. Or maybe they were just ignored, poorly documented, or still untranslated.
I'm talking mostly from a East German perspective in the late 70s and 80s (so quite late). I actually need to find out whether Lysenkoism was taken seriously in 1950's East Germany or whether it was silently ignored (open rebellion wouldn't have gone well with the 'Big Brother' in the East).
But the communists are smarter than the free world, at least the Americans, which I take it to represent the peak of capitalism and western liberal traditions. The PRC literacy rate is 96.67%, the USA is 79%. In 1937 the Soviet literacy rate was 75%, the USA appears to have been 97% literate then? [1] so somehow the Americans have become nearly as illiterate as a recently industrialized nation of peasants.
Ah, apparently late 70s literacy rate in the Soviet Union was 99.7%. [2].
> but nobody believed in communism either
I really recommend reading some Mao/Stalin era publications, not just from folks like Lenin but general notes from standing committees or national congresses. Even today the national congress of the PRC will get into all sorts of debates about communism. I don't believe their current system is socialist, but they sure do, and there's no doubt that there were a lot of true believers around Mao. I strongly doubt the cultural revolution or red guard could have happened without a lot of peasants genuinely believing in the cause.

Edit: Cuba's literacy rate is 98% lol https://data.worldbank.org/indicator/SE.ADT.LITR.ZS?location...
This should be obvious if you’ve ever been to a restaurant or airport in the USA, do you really think 1 in 5 adults can’t read a menu?
