I've also found this to be true, but also only in relatively modern times. For instance during the Cold War there was an obscene amount of propaganda, but it was mostly true. For instance the wide array of cheap affordable goods in American shelves was constantly flaunted, but not in the least bit misleading.

I don't understand the modern effort to engage in 'information warfare' as a thing in and of itself. Each time it collapses and people sees what was 'really' happening, it just makes them that much less likely to believe you next time. And you also create a significant number of perpetually jaded people who will basically never believe you again, even when you're telling the truth. Countless politicians have proudly paraded around their pristine, seemingly untouched, copies of Meditations, but perhaps they should go for more foundational works, like The Boy Who Cried Wolf.
