Oh, I didn't realize your OP was actually a satire. I intentionally ignored that part because well, you can always take whatever meaningful informations out of anything including stupidly apparent ads. As the other comment said, the whisper part is a well-known strategy as well.

If I take this concept seriously for a few seconds, it's one massive exercise in begging the question. The argument boils down to "notice when you do something wrong" while simultaneously admitting that people don't do that. And the ad's advice for doing it? Do it. What?!
That's profoundly stupid as a concept, where "profoundly stupid" here is defined specifically as an argument with a clear reasoning issue.
