We live in a world dominated by marketing, and marketing above all loves to feed narcissism, because narcissists are needy. If you want to believe that you are special, when you are not, and by definition being special is rare, then you will need constant fake evidence of that, to keep away the doubts. And, buy my product, because, people who own this are special. Is always the number one marketing ploy, whether it be a manufactured physical product, like a car, or an immaterial one like a belief system. So that our marketing culture does all that it can to normalize narcissism.

While sadly the one thing that narcissists are least happy with, is the plain, truthful and honest answer to the vast majority of questions, indeed nearly all questions, which is. "I don't know." The narcissist has to have the answers to the big questions, (And even small ones.) because they are surrounded by people who pretend they do, and you can not be, even a bit, less knowing than your neighbor if you are really someone special. While the more extreme the answers, the more special to a mind kept unnaturally immature by indoctrination, they will seem.

So that in a sales and marketing based culture, yes, the number of people who believe in crystals, UFOs, ghosts, Bigfoot, and even, "I am a victim of conspiracy." will increase and multiply.
