You Should Be Skeptical Your Faith Passes the Outsider Test for Faith

I have heard from several Christians who claim to have bit the bullet by admitting their faith should pass the Outsider Test for Faith (OTF), only to conclude that it does. Surprise! The fullest presentation of it online is to be found here. Having received this feedback I revisited the argument again in a chapter for The Christian Delusion. One of the many things I do in that chapter is to argue that Christians ought to be just as skeptical their own faith passes the OTF as they are when Mormons or Muslims claim the same thing. Why not, right? That's what outsiders do.
