Well, yes. It's not a new concept; it was a staple of Cold War sci-fi like The Three Stigmata, and we know from studies of e.g. Pentacostal worship that it is pretty easy to broadcast a suggestion to a large group of vulnerable people and get at least some of them to radically alter their worldview. We also know a reliable formula for changing people's beliefs; we use the same formula in sensitivity training as we did in MKUltra, including belief challenges, suspension of disbelief, induction/inception, lovebombing, and depersonalization. We also have a constant train of psychologists attempting to nudgelord society, gently pushing mass suggestions and trying to slowly change opinions at scale.

Fundamentally your sneer is a little incomplete. MKUltra wasn't just about forcing people to challenge their beliefs via argumentation and occult indoctrination, but also psychoactive inhibition-lowering drugs. In this setting, the drugs are administered after institutionalization.
