I am trying to locate the person who did the University test with me and see if he will volunteer for some more tests on a GSR I have which is as accurate as the one at the University.
I am willing to buy the polygraph as soon as I have enough funds but need a partner to help with the experiments to hone then to perfection before making a claim to the JREF.
Self testing would indeed be a good idea. The ability to reproduce results on demand is the most important thing.
On the philosophical side, I'm curious how you've come to the conclusion that a GSR or polygraph in any way indicate a person's honesty. Certainly many people claim to believe GSRs and polygraphs will detect lies, but what if they are themselves lying and these machines don't work at all? Given your trouble with finding a single honest person in the world, I'm surprised you'd so willingly accept the word of others that these machines are useful in detecting lies. I suggest you test a machine yourself, see how the measurements change when you lie and tell the truth. If you have access to a computer that could record the results, you could have it randomize them and present them back to you. If in such a test you cannot correctly identify your own lies, you'd have to assume the machine doesn't work at all. Until you perform such a self-test, I don't see how you can just blindly accept that the machine works.
