Exactly. The way you get people to eventually adopt a whole new paradigm is by nudging them one tiny bit at a time, seek to change like 1% of their world view — whatever the lowest hanging fruit you can find.

Rinse and repeat, slowly as culture changes. Over many years, decades.

One generation later, the then-normalized world view can be diametrically opposed to what it had been for centuries, in many regards, even core aspects.

Such socio-cultural phenomena rarely last beyond 3-ish generations in history, though. More like 25 years. Usually the whole thing collapses under its own contradictions (not without friction, sometimes violent). But beyond a certain time under the spell, and/or if experienced too young, most people don't come back (not fully, not really). To this day you may hear old US politicians still believe old US propaganda (now all but officially acknowledged as such) that they simply can't shake off their world view.

It's one of those things that, when pushed too far for too long, society only moves on once most people who lived under that era have passed away, and new unaffected generations take over.
