Obviously, the interviewer is implying about loyalty to the state (“state” as in country, not a US State) or to an administration, and I know that they are implying that. But I am not loyal to an administration. But I know that’s what they actually meant.
How would the polygraph interpret it if I say “Yes”, because I’m answering based on my interpretation of loyalty to the constitution, but deep down, I full well know the implied question the interviewer is asking.

They don’t work.
They measure a bunch of vital information, but they are wrong almost as often as they are right. They’re total garbage
Not only are they made up indicators, they are operated by someone who does a subjective reading of the output!
They’re actually only about 48% accurate, meaning that they’re more often wrong than right and you are 2% more likely to guess the right answer.
For this reason, they are inadmissible as evidence in court in Canada and the US, and possibly other places too.
Wait what are the Bayesian priors? Are we assuming that the baseline is 50% true and 50% false? And what is its error rate in false positives versus false negatives? Because all these matter for determining after the fact how much probability to assign the test being right or wrong.
Put another way, imagine a stupid device that just says “true” literally every time. If I hook that device up to a person who never lies, then that machine is 100% accurate! If I hook that same device to a person who only lies 5% of the time, it’s still 95% accurate.
So what do you mean by 48% accurate? That’s not enough information to do anything with.
