It's no more a "comforting lie" than your driving instructor telling you to check your blind spot. Not everyone does it, and bad things happen as a result, but all the more important to teach it.
I'm actually surprised to hear of high school teaching good scientific practice. I don't remember ever being taught that. Widely may it spread.
Hold on -- there's a category confusion here: "check your blindspots" isn't a comforting lie; it's a command. Converting it to "checking your blindspots will avoid collisions with careless drivers" would make it no longer a lie.
I was pointing out the category confusion. Science teachers don't purport to tell you what scientists actually do (history or sociology teachers might, I suppose, but they don't usually "make such a big deal" out of the scientific method). They purport to teach science.
As you say - it's not a comforting lie, it's a command.
