"Stealth religions": interesting essay on objectivism, atheism, and other non-standard "religions" from a well-defined functional perspective.
The main purpose of a religion or a stealth religion, however, is not to describe the real world but to motivate a given suite of behaviors. One way to do this is by creating a stylized world without tradeoffs, in which the prescribed behaviors are portrayed as good, good, good for everyone and the prohibited behaviors are portrayed as bad, bad, bad for everyone. Behaviors with mixed effects are absent from the stylized world because they do not clearly tell the believer what to do.
This might be a good working definition for the work of a "false prophet" (see Matthew 24:11).

"The presentation or 'gift' of the Holy Ghost simply confers upon a man the right to receive at any time, when he is worthy of it and desires it, the power and light of truth of the Holy Ghost, although he may often be left to his own spirit and judgment." --Joseph F. Smith (manual, p. 69)
