The bar isn't "too" high, it's somewhere in the 347th E8 lie algebra dimension high. We already live among "ministries of truth", they're just called science journals and studies. No matter how objective a field may seem to outsiders (mathematics, physics, astrology and life sciences), it is often plagued by dogma. The best people can do is pick their battles on what to educate themselves about, and even then the validity of information they find is often suspect. This is the natural outcome of living in the gap after the information explosion yet before fully autonomous verification.
