Yes and no. For example, the e-meter pinch test does work and is true.The e-meter and what the reads and reactions mean is a complete deception.
You can say or imagine anything, even run Bugs Bunny cartoons and you will eventually find something humorous or get bored enough and the needle will F/N. That's how so many people can run lifetimes of having been Jesus. You can make it up, you can run cartoons, you can even run abstract art. I'm not kidding, I'm totally serious! The e-meter and the reads have nothing to do with running things in or out. It has nothing to do with blowing charge and is no sort of verification of past lives or anything like that. The e-meter and the definitions of needle reactions are a hoax.
That's not to say that it isn't helpful to talk about your problems to someone who listens. You don't need an e-meter for that, though.
The logical fallacy of this is if A implies B does that mean that, therefore, B implies A? No.
All chevy camaros are automobiles but this does not logically imply that all automobiles are, therefore, chevy camaros.
If you get an e-meter read on some item, which is correct, does that mean, therefore, that everything that reads is historically correct? No.
