Perhaps I'm misusing the term. In conditional probability I use the term a priori to speak of P(A) before one calculates P(A|B) which can be calculated as P(B|A) * P(A) / P(B) by Bayesian analysis.
So it appears I have misused the term we have not used Bayes' formula in our discussion. However, if one simply removes "a-priori" my point
If I claim an alien just visited my house, and gave me a text related to extraterrestrial planets and beings, would you find it worth your time to look for evidences of the truthfulness of the text? Or would my claim regarding the 'production' of the text be enough to warrant your dismissal of it?
Depends in part on how much effort it would be for me to examine it and what I think hangs in the balance. While I find extraterrestrials to be unlikely, I still consider it interesting enough to look now and then. Of course with many purported cases of this sort of stuff I certainly can't examine them all so it becomes necassary for me to ask which ones are most interesting to study further.
Still, I figure that as long as critics are examining the Book of Abraham, they may as well examine the text too. Similarly I would imagine that I may as well examine your text if I go through the trouble of examining your home for forensic evidence of extraterrestrials--or of your handwriting on the papers.
