No, it doesn't make more sense.  It just shows how gullible you are to believe everything you read on this site.  Keep in mind the vast majority or posters here are those who failed their poly for any number of reasons, INCLUDING being deceptive or attempting to pass by dishonest means (countermeasures).

Comparing polygraph training to barber training is a George Maschke-ism, someone who failed not one, but two polygraph exams with two different agencies, and attempted to use countermeasures (a fact he still continues to deny after 15+ years).  Again, keep in mind those who make this ridiculous analogy-people who failed their polygraph.

Finally, I don't know what download you refer to regarding so-called red flags for saying one is religious, but I can assure you that the Department of Defense does not tolerate the probing of religious beliefs as part of any polygraph test.
