Theists, are you immune to being decieved?

Usually delusional people show signs of their problem in multiple contexts, like interpersonal relations. I don't see how you could claim that an otherwise competing person is delusional just because they have interpreted a very small number of experiences differently than you would.

True. There is a difference between being mistaken about something and being delusional. 'Squirrels report my activities to the NSA' is a delusion. 'I believe what I was raised to believe and what most people important to me believe' may be a mistake, it may reflect a failure to examine the belief closely and objectively, but it's not a delusion in the sense of being a symptom of mental illness.

Until fairly recently, I believed Daddy Longlegs were dangerously poisonous. If I trusted my parents and pastor more than anonymous scientists on such matters, I might still believe it.
