It absolutely matters. If you get nervous because of a question, even though you answer it honestly, it could flag you as lying. Like in my example. Baseline was fine, then they asked if he did drugs. He had, and admitted so, nervously.
And yet, you don't know if the machine indicated deception or not. He might have been rejected for admitting to doing drugs. It does not "flag you as lying" at all; the information it gives is not yes/no. It requires a trained operator to read it, and part of the operator's job is to ferrett out false positives. I know of one instance of a woman spiking the indicators through the roof at the question "have you ever committed a serious crime?" The reason was that she had been raped and so the reference to "serious crime" caused her to massively stress out. She was still hired for the position because the operator figured out what was going on.
It is entirely possible your friend had a shitty operator. That's my beef with the tests; not the concept but the fact that it requires a very, very skilled operator and yet it is not all that hard AFAIK to get certified to operate one. It is also possible that he was rejected because whoever commissioned the test in the first place had unrealistic expectations of it.

Furthermore, another individual was rejected because he was too nervous to even have a baseline developed.
Really? And this is a problem because...? If a person is so nervous about a polygraph that they can't even take the test, it's probably because either A) they know they have something to hide or B) they can't handle stress at all, in which case it's very questionable if they should be in any position that requires on in the first place.

Sure, but the application of the combination of the machine and operator is horrendous.
Except that it isn't. the technological premise is quite sound, although the technology will probably continue to experience significant improvement in coming years. There's nothing wrong with the "combination of operator and machine, either." The
operator himself can be horrendous, and that certainly is a problem with it, and one of my big issues with their use in more sensitive arenas; I believe operators are susceptible to developing an attitude that they expect deception. That isn't a problem with the technology; it's an issue of training, and that operators need their work checked by someone else for quality control.
A standalone machine, by the way, is not susceptible to operator bias.

No, and again these are multiple people, they did not fail for answering the question. The follow-up discussions were along the lines of "we KNOW you are lying about this" etc.
Look, I'm not going to just take your word for it. You're giving me one-line information about circumstances and people I don't know, about a process that takes hours and hours, and for which you probably weren't present wither and about which you already demonstrated several basic misconceptions. Sorry, your anecdotal evidence just doesn't cut it and I'm not going to waste time trying to talk about examples where you can just selectively dole out whatever facts you choose from those that you happen to remember even IF you were given truthful and complete information to begin with.
If you want to discuss the technological issues, fine, but I'm not going to spend any more time on your anecdotes. As far as I'm concerned they don't exist.

While true, recent applications of similar technology can at least establish your baseline. And right now, that baseline is "suck".
This line doesn't even make sense. In fact, unless you're just engaging in pointless snark, it indicates you don't even understand what baseline I'm talking about. The baseline I'm talking about is the baseline "level of arousal" (yes yes, sexual puns here) a person exhibits before any questions are asked, and how those baselines compare to specific questions later on. I'm not talking about the baseline level of performance of the technology. Furthermore, I don't see that you're in any position to say that it "sucks" beyond some exceedingly vague send-hand anecdotes.
There's an effect, the wikipedia link to it has been linked in the past, about Americans assuming they know far more about subjects they are ignorant on than they actually do.
