...I've usually put up my own red flag, when a non-classical theory framework is discussed, (subjects like 'Quantum' physics are notorious, in other threads.)
Listened, recently, to some 'medical' descriptions, blatent abuse of terms like 'frequency'...as in "Bad frequencies must be purged...by flooding the Patient's body, with cancellation waves...".
Those frequency cancelling effects seem to forget, about wave phase relations, in other material I've seen.
Just reminded me, as seen elsewhere.
