Err, no. You are wrong here and Claus is right. Let me try to explain by way of analogy.
Suppose you were testing the hiss from two different sets of speakers in a car. You wanted to know which one was "quieter", had less hiss. But while you were testing, the car was being run through a carwash, then through heavy traffic, all with the radio on full blast. Out of all the measurements you get from in or near the speakers, which of it is the "hiss" you are trying to measure? It is literally drowned out by the background noise from and around the speakers. To get valid results you need to do it in a perfectly quiet place, don't you. Eliminate all but one variable in the test.
Now, back to PEAR's REGs. They are supposed to produce a perfectly random series of bits when they are not being influenced by "global consciousness". When they ARE being influenced, the random series of bits they produce supposedly becomes non-random - that's the nature of the experiment they are running: to find that non-randomness.
The problem is that this "global consciousness" cannot be turned off. It is omnipresent and ubiquitous, and therefore it MUST affect the REGs all the time. There is no switch to eliminate it, no lead shield thick enough, etc. So how can the REGs be "calibrated" in the first place under all this external influence of the very effect it is supposed to be measureing...?? And if they can't be calibrated, what good is the data they ultimately produce?
