The test is right 90% of the time. It doesn't have a 90% chance of being right when it pronounces someone sick.

You're obviously right mathematically, I'm not trying to say the number is wrong. This is a question of semantics... I was mereley arguing that the following series of words is also a correct and logical statement:

A test is right 90% of the time. Someone takes the test and receives a result. Therefore, 90% of the time, the result is right.

I make no attempt to disprove Bayes Theorem, but argue that syntax and semantics are valid components for logical theory.
