"But wait," you say. "Scientology didn't invent that; they probably just pulled it off of some '10 Tips to Work Better' email forward. It's just common sense!"
Right, and so is virtually everything on their course list. Their process for how to organize a group project is probably identical to one you're already using at the office, and it works great:
But here's the key: When a Scientologist (or Muslim, or Christian, or yoga enthusiast) says it works for them, this is what they're talking about. The mythology isn't important -- if these rituals have saved your life and later on a teacher says, "Yeah, this technique works because of the ancient thetans that live in your asshole," you're going to shrug and say, "Sure, sounds good." If you tell the lady in yoga class that the reason she feels better afterward is because negative spiritual energies tend to pool in the hip joints, you'll get the same reaction.
"Yoga pants contain these energies so you can attack them. That's why it's so important to visit my Etsy shop."
Then if you, as a cool, rational person, butt in and say, "Actually, yoga is just engaging the endonomic nervous system and reducing cortisol levels," all they're going to hear is you replacing a very easy-to-understand explanation with a very complicated one that sounds like gibberish. If you smirk and roll your eyes at these gullible lemmings, then go grab a mirror and smirk at yourself, partner, because you do it too.
You physically don't have room in your brain to keep track of how everything in your world works (shit, you don't even really know how your brain works) so you can feel all superior to a Christian who doesn't believe in evolution, but somewhere there's an engineer who feels superior to you for not knowing how your iPhone works (and you know "endonomic nervous system" is just a nonsense phrase I made up, right?). The reality is that you don't know how your iPhone works because knowing that wouldn't change your day-to-day use of it at all. Likewise, thinking the Earth is only 6,000 years old doesn't make it any harder to have, say, a career repairing air conditioners. But believing that self-discipline, patience, and hard work are sacred virtues from God definitely makes it easier.
