Spectacularly so in the case of the Waterfall software development process. It's as if the "classic" in question had said "Drowning kittens" at the end of page 1, and of course the beginning of page 2 goes right on to say "...is evil, don't do it". But everyone reads page one which has a lovely diagram and goes, "Oh yeah; drowning kittens. Wonderful idea, let's make that the official government norm for feline management."
