That (3) is a very interesting issue. My suspicion is, it basically says "knowing logics is good for your well-being". The skill of logical inference — even at the level of very basic syllogisms — is both very much underappreciated and underdeveloped in the American college population, at least from my personal experience.

I predict it will do much good... and if I'm wrong, it certainly won't do any harm!
